◇ In April 2018, General Secretary Xi Jinping emphasized during his inspection in Hainan that the National Nanfan Scientific Research and Breeding Base is a valuable agricultural scientific research platform for the country, and it must be built into a national service that integrates scientific research, production, sales, scientific and technological exchanges, and achievement transformation."Nanfan Silicon Valley".

◇Bearing in mind the General Secretary's ardent instructions and fully implementing the national plan, Hainan anchors the goal of self-reliance in science and technology in the seed industry and independent control of seed sources, and makes every effort to promote the construction of Nanfan Silicon Valley-lay out a major national scientific and technological innovation platform, improve systems and mechanisms to gather resource elements, cultivate modern seed industry clusters by "striving to strengthen seeds", promote the rapid implementation of good varieties and good technologies, and help secure Chinese seeds and secure China's rice bowl.

◇"There is no need to make special appointments with breeders here. You can find people to communicate with when you walk to the fields." She said happily that the number of WeChat friends added here in one day is more than in the past month.

◇At the Potian Yangnanfan Service Station in Yazhou District, Sun Jixian, the person in charge, opened the Nanfan Shared Land Service Platform, and the area, rent, supporting water conservancy, and road facilities of each plot were clearly visible. He said: "We have built an information service platform to find farmland, agricultural machinery, and workers online."

◇Guo Xiayu, associate researcher at the National Salt-Tolerant Rice Technology Innovation Center, said that the center has joined forces with 18 salt-tolerant rice scientific research units across the country to establish the "Salt-Tolerant Rice Regional Test Consortium" to organize and implement the independent test of special types of national salt-tolerant (alkali) rice varieties to provide variety support to achieve the promotion and application goal of 100 million acres.

◇The cultivation of major tropical crops in my country has achieved a replacement from introducing trial varieties to independently selected varieties.

◇With the arrival of the "Breeding 4.0" era where new biotechnology, big data, artificial intelligence and other technologies are integrated, the creation of new varieties is constantly accelerating.

Located at 18 degrees north latitude, the alluvial plain along the Yazhou Bay has sufficient heat and heat and no winter all year round, making it an ideal place for breeding and additional generations. In the vast fields, the innovation highland of the seed industry is accelerating.

In Sanya Yazhou Bay Science and Technology City, scientific researchers travel between laboratories and experimental fields to carry out scientific research, teach graduate students in the teaching building, and participate in academic exchanges in the conference room. "Working here is like being a visiting scholar." Xu Miaoyun, a researcher at the Institute of Biotechnology, Chinese Academy of Agricultural Sciences, lamented that experts from different units and disciplines gather together. In an open and inclusive innovation atmosphere, sparks of collision of ideas frequently burst out.

Since the 1950s, scientific researchers from all over the country have begun to carry out southern breeding in Sanya, Lingshui, Ledong and other places in Hainan. The Nanfan base located in these three cities and counties has become the largest agricultural science and technology experimental area in my country. From Yuan Longping's discovery of the magical wild rice and opening a breakthrough in hybrid rice research, to thousands of breeders who "pursue the light and heat" scientific research and breeding, each improved seed has gone through thousands of tempering and has opened branches and leaves across the country.

More than 70% of the newly bred crop varieties in my country have been bred and bred in southern China. Nanfan has made important contributions to building a solid rice bowl in China. It has become an "incubator" for my country's agricultural science and technology innovation, an "accelerator" for new variety breeding, a "voltage stabilization library" to ensure production seeds, and an "appraisal room" for natural seed quality.".

In 2015, the "National Nanhua Scientific Research and Breeding Base (Hainan) Construction Plan (2015-2025)" was issued, delimiting a 268,000-acre scientific research and breeding reserve. The construction of Nanfan base has since become a national strategic project.

In April 2018, General Secretary Xi Jinping emphasized during his inspection in Hainan that the National Nanfan Scientific Research and Breeding Base is a valuable agricultural scientific research platform for the country, and it must be built into a "Nanfan Silicon Valley" that integrates scientific research, production, sales, scientific and technological exchanges, and achievement transformation to serve the whole country.

In January this year, the "National Nanfan Silicon Valley Construction Plan (2023-2030)"(hereinafter referred to as the "Plan") was issued, proposing that efforts should be made to build Nanfan Silicon Valley into a national-level seed industry innovation base, a new engine for high-quality development of the seed industry, a large platform for international cooperation in science and technology and a pilot zone for deepening reform and opening up in the seed industry.

Bearing in mind the General Secretary's ardent instructions and fully implementing the national plan, Hainan anchors the goal of self-reliance in science and technology in the seed industry and independent control of seed sources, and makes every effort to promote the construction of Nanfan Silicon Valley-lay out a major national scientific and technological innovation platform, improve systems and mechanisms to gather resource elements, cultivate modern seed industry clusters by "striving to strengthen seeds", promote the rapid implementation of good varieties and good technologies, and help secure Chinese seeds and secure China's rice bowl.

At the scientific research and test base of the Yazhou Bay Headquarters of the National Salt-Tolerant Rice Technology Innovation Center in Sanya, a high-standard experimental field, a salt pond for accurate identification of salinity (alkali) properties, an automatic rain-proof steel shed, and an intelligent monitoring system for water and soil salinity have been built.

Connect the entire chain of industry, academia and research

Nanfan Silicon Valley is accelerating the construction of a seed industry innovation and development system integrating industry, academia and application, gathering a number of seed industry innovation scientific research units and leading enterprises, laying out and building a major seed industry innovation platform, and gradually taking shape in modern seed industry industrial clusters.

Build a platform and gather talents, and there is a strong atmosphere of collaborative innovation. The Yazhou Bay Laboratory has been put into operation, the National Key Laboratory of Tropical Crop Biological Breeding and the Key Laboratory of Gene Editing and Innovative Utilization (Hainan) have been launched in Hainan, and the National Nanfan Crop Phenotype Research Facility and the National Wild Rice Germplasm Resource Garden have been completed and put into operation. The construction of Sanya International Corn Transformation Center and Soybean Horticultural Crop Germplasm Innovation Center projects has been accelerated... Focusing on building a national-level seed industry innovation base, Nanfan Silicon Valley has laid out and built a number of major scientific research platforms. Introduce scientific research forces from 21 agriculture-related scientific research institutes and universities such as the Chinese Academy of Agricultural Sciences, China Agricultural University, and Nanjing Agricultural University, and carry out in-depth cooperation around basic theoretical research, key technology research and development, and major new varieties cultivation in the seed industry field.

Since the beginning of this year, Yazhou Bay Laboratory has recruited many times from around the world, recruiting outstanding scientists in the fields of rice, corn, wheat, soybeans and other crops breeding, as well as agricultural multidimensional omics, nutritional synthetic biotechnology and other fields. For more than a year, Li Jiayang, director of the laboratory and academician of the Chinese Academy of Sciences, has been busy expanding the talent team and promoting various scientific research projects. He said: "It is necessary to speed up the cultivation of new strategic varieties and strive to make my country's seed industry innovation reach the international leading level in a short period of time."

At the end of 2020, Li Huihui, chief of the big data intelligent design and breeding team of the Chinese Academy of Agricultural Sciences, came to Sanya to work. She hopes to use big data, artificial intelligence and other technologies to shorten the breeding process. To this end, she must fully understand the needs of breeders. "There is no need to make special appointments with breeders here. You can find people to communicate with when you walk to the fields." She said happily that the number of WeChat friends added here in one day is more than in the past month.

Build mechanisms, promote cooperation, and integrate enterprises and science to accelerate the transformation of results. To open up R & D and market, Hainan actively promotes the "unveiling and leading the list" project system in the field of seed industry, establishes relevant mechanisms such as enterprise formulation, institution formulation, achievement sharing, and benefit feedback, and promotes the integrated development of enterprise and science and accelerates the transformation of scientific research results in southern China.

Since 2021, the Hainan Province Seed Industry Laboratory and China Seed Group, a subsidiary of Syngenta Group China, BGI and other companies have jointly carried out multiple batches of "unveiling the list and taking charge" project cooperation. Huang Hefei, director of the Industry Promotion Department of the Seed Industry Laboratory of Hainan Province, said that the entire process of the project from project establishment, execution to acceptance highlights the result-oriented approach. The assessment indicator is not to issue papers or apply for patents. The key depends on whether the results can be used by the industry.

Since the launch of the first batch of "unveiling the list and taking charge" projects in early 2023, China Seed Group has launched a number of cooperation projects with 67 scientific research units. So far, 8 patents have been applied, 8 variety rights have been accepted, and 6 varieties have been approved.

The "Unveiling" project team of corn lodging resistance gene mining and germplasm innovation led by Xu Miaoyun, a researcher at the Institute of Biotechnology, Chinese Academy of Agricultural Sciences, has unearthed 8 genes with clear lodging resistance functions. "With traditional scientific research methods, it takes as early as 5 years to go from mining genes to verifying the effects in production, verifying that the genes are effective and then looking for companies to discuss cooperation." She said that now that all parties cooperate closely and all tasks are carried out simultaneously, the time for industrial breeding can be shortened by half.

Feng Weizhe, dean of the Sanya Research Institute of China Agricultural University, said that the research institute has established a complete technology transfer system to ensure that scientific research results can be smoothly transformed and applied to actual production. A number of new varieties of fresh corn with high yield, disease resistance and stress resistance cultivated by Professor Li Jiansheng of China Agricultural University have been quickly promoted to many cities and counties in Hainan through technology transfer. Currently, the planting area in the province reaches hundreds of thousands of acres.

Extend, supplement and strengthen chains, and cultivate and strengthen seed industry clusters. In order to implement the Plan's proposal to strive to build Ninfan Silicon Valley into a new engine for high-quality development of the seed industry, Hainan promotes the upgrading of the Ninfan industry from simple breeding to the entire industry chain of the seed industry, and accelerates the cultivation of modern industrial clusters in the Ninfan industry. At present, Hainan has gathered more than 2800 innovative enterprises in the seed industry. Last year, the output value of Nanfan Seed Industry exceeded 12 billion yuan, a year-on-year increase of 50%.

In 2021, the headquarters of China Seed Group will move to Sanya Yazhou Bay Science and Technology City, which has now led to the arrival of more than ten strategic business units in the seed industry. "From front-end breeding research and development to back-end achievement transformation, we have gathered various entities to actively open up innovation chains and industrial chains." Zhang Xiaoqiang, director of strategy and government affairs of China Seed Group, said that the main entities involved include R & D institutions such as Syngenta Group's National Key Laboratory of Germplasm Innovation and Molecular Breeding of Corn and Other Crops, Jianghuai Horticulture Research Institute, Quan Yin Wuxing Seed Co., Ltd. Seed industry enterprises, as well as industry enabling entities such as Syngenta Group's Biological Breeding Industry Training Center.

The accelerated layout of Zhongzhong Group is the epitome of the accelerated construction of Ninfan's modern seed industry system. Using Sanya Yazhou Bay Science and Technology City as a carrier, Hainan continues to introduce domestic and foreign high-quality seed industry enterprises and related industries enterprises and R & D teams, and opens up a NANFAN industry chain that integrates testing front-end, field services, laboratory management, achievement transformation, and operating income generation. Guo Liezhong, director of the Seed Industry Management Division of the Department of Agriculture and Rural Affairs of Hainan Province, said that Hainan is also exploring the development of the modern service industry of Nanfan with CRO (Contract Research Organization) as the core. Last year, 15 CRO entities of Nanfan seed industry with a certain output value were identified for the first time, providing scientific research services such as purity identification, DNA extraction, and variety testing for Nanfan units.

While a large number of enterprises are stationed, a number of innovation leaders are emerging at an accelerated pace. Five years ago, when Longping Biotechnology (Hainan) Co., Ltd. was registered and established in Yazhou Bay Science and Technology City, the entrepreneurial team had less than 10 people. Now the team size has expanded to 130 people. The company has pioneered the research and development technology of multi-gene molecular superimposed trait products in China. As of the end of 2023, it has obtained a total of 91 authorized invention patents at home and abroad, and has grown into a "national intellectual property advantage enterprise."

"Nanfan Silicon Valley industrial clusters continue to gather in Yazhou Bay, driving the coordinated development of the seed industry chain." The relevant person in charge of Sanya Yazhou Bay Science and Technology City Administration Bureau said that from the Nanfan base to the Nanfan Silicon Valley, from the gathering of seed industry talents to the breeding of innovative seed varieties in the seed industry, to the establishment of technology-based seed industry companies for domestic and international markets, Hainan is comprehensively promoting the integration of industry, academia and application in China's modern seed industry, injecting new momentum into the national seed industry revitalization action.

Serving national seed industry innovation

In order to serve the revitalization of the national seed industry, Hainan continues to improve the "software and hardware" level of Nanfan, focuses on major needs to ensure food security, and actively builds an open platform for international cooperation in the seed industry.

Improve the level of "software and hardware" to ensure the scientific research needs of various places in Nanfang. In the past, people from Lao Nanfan often rushed around looking for land and workers. Today, at the Potian Yangnanfan Service Station in Yazhou District, Sun Jixian, the person in charge, has opened the Nanfan Shared Land Service Platform. The area, rent, supporting water conservancy, and road facilities of each plot are clear at a glance. He said: "We have built an information service platform to find farmland, agricultural machinery, and workers online."

The reporter saw at the Large-scale Instrument Public Service Center of the Seed Industry Laboratory of Hainan Province that various advanced instruments and equipment were busy running. After making online reservations, scientific researchers from various units could scan the code on site and start using it. From its start of operation in December 2021 to the end of last year, the laboratory has accepted more than 2100 appointments for shared instruments and equipment, with a total use of more than 25,000 hours.

In recent years, Hainan Province and the Ministry of Agriculture and Rural Affairs have worked closely together with relevant departments and provinces engaged in Nanfan scientific research to continuously improve the "software and hardware" guarantees of the Nanfan scientific research and breeding base:

--Nanfan scientific research and breeding land is "protected". 268,000 acres of protected areas have been designated and 53,000 acres of core areas have been built, fundamentally resolving the contradiction between other industries and Nanfan's "land competition".

--Infrastructure is "built". High-standard farmland in the reserve has been fully built, multiple scientific research, production and living supporting service areas have been "carried in", and a 5000-acre biological breeding area has been put into use; all provinces have increased financial support and built a stable provincial-level southern breeding base with high standards.

--Nanfan's management service level has been "improved". The "Regulations on the Management of Crop Seeds in Hainan Province" and "Measures for the Registration of Southern Farms in Hainan Province" were issued and implemented; the Intellectual Property Special Zone Trial Court and the New Agricultural Plant Variety Review and Cooperation Center were successively established to promote the "five-in-one" comprehensive management system reform of patents, trademarks, copyrights, geographical indications and intellectual property rights of new plant varieties.

The relevant person in charge of the Rural Economics Department of the National Development and Reform Commission stated that it will focus on improving the capabilities of scientific research and breeding, improved seed production, management services and safety management and control, and then lay out and build a number of major infrastructure, focusing on major scientific research facilities, high-standard breeding and seed production bases, seed industry support and guarantee systems, transfer of crop germplasm resources, and quarantine and isolation facilities for southern breeding plants.

Focus on ensuring food security and gather forces to coordinate key problems. At the scientific research and test base of the Yazhou Bay Headquarters of the National Salt-alkali-tolerant Rice Technology Innovation Center in Sanya, researchers plant various salt-alkali-tolerant rice varieties and materials under different salinities. An internationally leading salt-alkali-tolerant rice identification facility in an outdoor field environment has been built here. It is characterized by multi-salinity, large-scale, and intelligence. The annual accurate identification capacity reaches more than 100,000, and the annual variety test scale reaches more than 10,000.

There are 1.5 billion acres of saline-alkali land in my country, and tapping the potential of saline-alkali land is of great significance to ensuring food security. In view of the wide distribution and diverse types of saline-alkali land in my country, the National Salt-alkali-tolerant Rice Technology Innovation Center is constructed in the model of "headquarters, research center, regional sub-centers and test station/base". Guo Xiayu, associate researcher at the center, said that the center has joined forces with 18 salt-alkali tolerant rice scientific research units across the country to establish the "Salt-alkali Tolerant Rice Regional Test Consortium" to organize and implement independent tests on special types of national salt-tolerant (alkali) rice varieties, in order to achieve 100 million acres of promotion and application goals provide variety support.

Focusing on the problem of frequent insect pests in corn in North China, Northeast China and other places, the "Development and Application of Corn Resistance to Firefly bipunctum" project has been established; in response to the disease threats such as bacterial blight faced by South China rice areas, we will promptly screen disease-resistant materials and Cultivate varieties... Focusing on solving the "pain points" of agricultural production and farmers 'income increase in various places, a large number of collaborative scientific research projects are being implemented in Hainan.

As the "hard core" support of Nanfan Silicon Valley, Yazhou Bay Laboratory targets the major needs of national food security and scientific and technological frontiers, and concentrates superior resources and strength to continue to carry out strategic, forward-looking, and basic major scientific issues and key core scientific issues in agricultural biological breeding. Technical research. Qian Qian, academician of the Chinese Academy of Sciences and deputy director of the Yazhou Bay Laboratory, said: "As a national strategic scientific and technological force based in Nanfan Silicon Valley and taking seed industry innovation as its own responsibility, the laboratory must maintain the strategic determination to draw a blueprint to the end and stick to the green mountains. Don't relax and pursue innovation down-to-earth."

Build a bridge for international cooperation and build the frontier of opening up in my country's seed industry. Hainan continues to explore institutional integration and innovation, and continuously improves the level of introduction facilitation: promote the delegation of approval authority for seed import and export production and operation licenses to Hainan, establish and improve the "three-in-one" working mechanism for the introduction of transfer bases for agriculture, forestry, and customs, and innovate "imported plants" The mechanism for assessment and mutual recognition of isolated planting sites for propagation materials opens a fast channel for seed entry inspection...

The Department of Agriculture and Rural Affairs of Hainan Province, the Forestry Bureau of Hainan Province, Haikou Customs and Sanya City have established a cross-departmental linkage working mechanism and established a service center for the introduction of transfer bases to proactively serve business entities. Since 2018, the introduction transfer base has successfully introduced a total of 720 batches of animal and plant germplasm resources, with more than 1000 resources.

Building a global seed industry cooperation and exchange platform and a pilot zone for deepening reform and opening up in the seed industry is an important construction goal for Nanfan Silicon Valley.

The soybean research team of Nanjing Agricultural University continues to identify the adaptability of soybean germplasm resources to tropical environments and screen high-yield varieties in Sanya. The team has selected several varieties with strong adaptability to tropical environments and tested them in Laos through a cooperation mechanism. Compared with local varieties, the tested varieties have the characteristics of short growth period and high yield, showing high yield.

On the basis of preliminary work, the Sanya Research Institute of Nanjing Agricultural University has established the "Belt and Road" Soybean Biological Breeding Hainan Province Engineering Research Center. Associate Professor Zhang Jiaoping, deputy director of the National Soybean Improvement Center of Nanjing Agricultural University, said that the center will give full play to my country's advantages in soybean variety selection, cultivation techniques, germplasm research and development, develop and utilize Southeast Asian soybean germplasm resources, and help Southeast Asian countries develop soybeans. Industry, cultivate agricultural talents, achieve poverty reduction for farmers, and at the same time cultivate new soybean planting areas and sell them back to China to achieve a win-win situation for all parties.

Hold the seeds firmly in your hands

Germplasm resources are the "source of living water" for breeding innovation. In Yazhou District, more than 10,000 wild rice varieties have "settled" in the National Wild Rice Germplasm Resource Garden. Resources are preserved here in the form of plant planting, which is conducive to the exploration and utilization of excellent traits and the cultivation of breakthrough varieties.

Zheng Xiaoming, chief of the Wild Crop Germplasm Resources Protection and Utilization Team of the Chinese Academy of Agricultural Sciences, and his colleagues traveled all over the country and went to more than 10 countries to collect wild rice, and continued to carry out the evaluation and identification of wild rice resources, laying the foundation for the effective utilization of resources. "Without human intervention, wild rice has faced the wind and rain of nature and has multiplied for tens of millions of years. It is an indispensable resource for future agriculture." Zheng Xiaoming said that she and her team have made positive progress in using wild rice to explore salt-alkali tolerance and pest resistance genes.

Among the first batch of 72 national crop germplasm resource banks (nurseries) announced by the Ministry of Agriculture and Rural Affairs in 2022, a total of 7 in Hainan were selected. Among them, the Chinese Academy of Tropical Agricultural Sciences is the supporting unit for six national crop planting resource nurseries, including rubber, tropical forage, cassava, and tropical spice drinks.

Wang Jiabao, vice president of the Chinese Academy of Thermal Sciences, said that the total collection of tropical crop germplasm resources in my country exceeds 70,000, which greatly enriches my country's strategic reserve of tropical crop resources. Through systematic evaluation of germplasm resources, more than 3000 excellent germplasm materials were screened and created. Based on the collected and preserved germplasm resources, more than 300 new varieties such as rubber trees, tropical fruit trees, coconuts, sugarcane, coffee, and tropical forage have been selected. The cultivation of major tropical crops in my country has achieved the transformation from introduction of pilot varieties to independent breeding. Variety replacement.

The birth of breakthrough varieties can change the destiny of an industry. In the past, affected by banana blight, the planting area of banana, the fifth largest fruit in my country, was once halved. In recent years, the national banana (mango) industry technical system has continued to tackle key problems and cultivated disease-resistant varieties such as "Zhongre No. 1" and "Baodao Banana". In just a few years of promotion, it has covered about a quarter of my country's planting area. The research and application of comprehensive prevention and control technology for banana blight with disease-resistant varieties as the core have continued to advance, helping my country achieve preventable and controllable banana blight.

Xie Jianghui, chief scientist of the National Banana (Mango) Industrial Technology System and vice president of the Chinese Academy of Thermal Sciences, said that "Zhongre No. 1" is a highly resistant banana blight disease that was transformed by cobalt 60 radiation and was bred through multiple generations of targeted breeding. New variety, leading the world in disease resistance. This variety has achieved technology transfer authorization and is currently promoted and sold by seed companies.

Nanfan Silicon Valley is an "accelerator" for breeding good varieties and a "testing ground" for making good varieties stand out. Zhou Hua, director of rice evaluation at China National Grain Group, said that there are a large number of testing and evaluation links in the cultivation of crop varieties from design to promotion. Taking advantage of Nanfan's unique light and heat conditions, he and his team carried out rice evaluation work back and forth on this anniversary, pushing each good variety to the fields. For example, the "Quanyou 607" launched in recent years has become the largest rice variety single product of Zhongzhong Group. It produces three to four million kilograms of rice every year and can supply three to four million acres of rice planting.

Traditional breeding requires observing the field performance of traits, continuous screening and combination, and the variety breeding cycle is long. With the arrival of the "Breeding 4.0" era where new biotechnology, big data, artificial intelligence and other technologies are integrated, the creation of new varieties is constantly accelerating.

Corn haploid breeding technology is known as the "high-speed rail technology" in the field of corn breeding, and this technology has greatly accelerated the breeding process. "Relying on the platform of China Agricultural University Sanya Research Institute to continue to carry out scientific research, the promotion and application of this technology in recent years can be described as 'rapid advancement'." Chen Shaojiang, a professor at China Agricultural University, said that the application of this technology has covered major corn breeding scientific research units across the country. At the same time, the application of this technology is expanding into the breeding fields of more than ten major crops such as wheat and tomatoes. Relying on this technology, a number of corn varieties that have been selected and bred in southern China have been promoted on a large scale. Varieties such as "Zhongnongda 678" have also been listed as the leading agricultural varieties and main promoted technologies of the Ministry of Agriculture and Rural Affairs, and have become excellent varieties promoted by the country.

Nanfan Silicon Valley is also actively deploying other cutting-edge technology research and development and opening up a new track for breeding innovation: Yazhou Bay Laboratory released the big language model of the seed industry "Fengdeng", filling the gap in the big model in my country's seed industry professional field; The Chinese Academy of Agricultural Sciences and Alibaba jointly released my country's first full-process smart breeding platform, committed to using AI algorithms to simulate the wisdom of breeders...

"New productivity in the seed industry is the seed industry innovation driven by high-level seed industry scientific and technological innovation and high-quality condition and capability guarantee." Qian Qian said that Nanfan Silicon Valley is the main front for cultivating new productivity in the seed industry. (text？| "Outlook" News Weekly reporter？ Chen Liangjie？ Wang Hui Yu？ Luojiang)
