“This is a plug seedling of strawberry, which integrates precise irrigation of strawberry with coordinated control of water and fertilizer, and applies green prevention and control of main pests and diseases of strawberry and light-filling technology, which can effectively improve the quality of our strawberry, and can also greatly reduce the amount of chemical fertilizer, responding to the national call for double reduction of fertilizer and medicine.” Li Weilong, special correspondent of Shaojiadu Science and Technology in Linhai, introduced.
This technology comes from Li Weilong’s collaborative promotion project of major agricultural technologies in the province, “High-quality Key Technology Demonstration of Strawberries”. In order to find out the cultivation characteristics, he goes to the greenhouse of the demonstration base, namely Wangda Fruit and Vegetable Professional Cooperative in Linhai City, every day to check the growth of strawberries, and inform the growers of the techniques of strawberry nutrition management, fertilizer dosage control, physical control of pests and diseases, etc., so as to lay a good foundation for large-scale promotion.
In recent years, Linhai City, focusing on the scientific and technological needs of “agriculture, rural areas and farmers” work, has promoted science and technology commissioners to provide all-round advanced scientific and technological services for farmers through project driving, platform building and mechanism construction, thus realizing the “accelerated run” of agriculture and contributing real scientific and technological strength to rural revitalization.
Take project driving as the fundamental point, and make good use of key measures of technology demonstration.
“Compared with chemical fertilizer, the application of 80% chemical fertilizer +20% fermentation products is beneficial to increase rice yield.” Qian Zhongcang, special correspondent of Yongfeng Town Science and Technology, introduced that since 2021, he has actively explored the technology of fertilizer and substrate utilization of processing waste of Cymbidium sinense, and carried out a pre-fermentation test with Cymbidium sinense stem and leaf waste and rice husk as the main raw materials, effectively avoiding sewage outflow without squeezing Cymbidium sinense stem and leaf waste to dehydrate, and making the fermentation product of Cymbidium sinense stem and leaf waste into substrate to realize efficient utilization of agricultural waste.
In addition, in order to help farmers cope with large-scale sudden pest control, and solve the problems such as difficulty in planting citrus in mountainous areas and great harm to operators caused by pesticides, Qian Zhongcang deeply studied the project of “Application and Popularization of Drone in Citrus Plant Protection”, focusing on reducing the dosage of citrus pesticides, reducing pesticide residues and improving pesticide control effect. This project has completed the preliminary research and pesticide debugging, and will begin the trial soon. It is expected that the labor cost per mu will be reduced by about 400 yuan after success, and the pesticide use will be reduced by 20% compared with manual spraying.
The achievement of the project can’t be achieved without the special support for science and technology special commissioners. In recent years, Linhai has continuously strengthened the special commissioners’ projects to help the high-quality development of agriculture. “We closely follow the industrial priorities of the vast rural areas in Linhai, and require each science and technology correspondent to carry out more than two key demonstration projects every year, so as to lead the demonstration for farmers and agricultural production enterprises, and promote new varieties, new technologies and new models point by point.” Hu Deguan, deputy director of Linhai Science and Technology Bureau, said.
At the same time, Linhai has actively established a mechanism for solving problems led by science and technology commissioners. Every year, according to farmers’ demands and research priorities of commissioners, a number of key research projects are selected and given key funding to effectively solve a number of technical problems of “sticking neck”. Wu Shaohui, a special agent of Yongquan Town, studied and found that spraying 30 times of plant sun-shading agent on the crown surface layer can reduce the daily burning rate of the crown surface fruit from 21.9% to 0.8 ~ 1.3%, aiming at the problems of mid-term fruit drop caused by sun burning and affecting the maturity of citrus. Zhu Minhua, the special agent of Tou Town, organized the establishment of 3,000 mu of red bayberry green prevention and control core demonstration base, with a radiation promotion area of 40,000 mu. The unit price per kilogram of planted high-quality fruit was higher than that of 3 yuan on average, and the annual benefit per mu increased by more than 1000 yuan. Lin Lingwei, a special correspondent of Xunqiao Town, explored the experiment and demonstration of Zizania latifolia facility cultivation, with the demonstration area of 13,340 square meters, realizing the yield increase of Zizania latifolia by more than 10% per mu, and the production time of Zizania latifolia was listed more than 30 days earlier. ……
In the past two years, Linhai Science and Technology Commissioner has obtained 49 agricultural science and technology projects at all levels, introduced more than 100 new varieties such as citrus, strawberry, western blue flower, tea, blueberry and kiwifruit, and carried out 50 special science and technology docking services to effectively solve more than 60 technical problems for agricultural production. By carrying out new variety promotion, disaster reduction and prevention and other services, Linhai farmers and agricultural production enterprises increased their direct economic income by nearly 300 million yuan, and guided the reduction of pests and diseases and disaster losses by nearly 100 million yuan.
Focus on platform construction, and make a good combination of achievements transformation.
It is another “password” for Linhai to unlock the advantages of special commissioners by establishing a platform for collaborative technological innovation and opening up channels for the transformation of scientific and technological achievements. In recent years, Linhai Science and Technology Bureau, together with the special commissioners, has sent units and relevant departments to work closely together to establish a platform for agricultural technology innovation, such as tripartite strategic cooperation with China Citrus Research Institute and Zhejiang Citrus Research Institute. Linhai Citrus Industry Technology Collaborative Innovation Center has been established, and scientific research work such as trial planting base, product introduction, experimental research and cold storage has been conducted by the special commissioners. In recent two years, more than 30 high-quality citrus varieties have been introduced, and greenhouse cultivation, Teweiqiang plastic film mulching to improve quality and sugar content, and prevention and control of citrus epidemic diseases have been actively carried out.
Agricultural Science and Technology Park is also an important carrier to accelerate the transfer and transformation of agricultural achievements. Provide platform support for the work of science and technology commissioners, explore a new mode of integration and development of agricultural products production, processing and sales with tourism, health, culture, information and other industries in Linhai, successfully establish a provincial agricultural science and technology park with Yangyan Tea Factory as the main body, realize another new breakthrough in the construction of high-level agricultural development platform of Taizhou tea industry, and become a golden signboard for the integration and development of the first, second and third industries in Linhai.
In addition, in order to vigorously promote the agricultural industry to create wealth, Linhai City relies on the scientific research achievements and technical advantages of science and technology commissioners, actively builds a platform for entrepreneurial innovation, and mobilizes farmers to join in entrepreneurial innovation activities. Since 2019, it has successfully built two provincial-level Star Creation World and one key production and sales platform of “leading enterprises+farmers”. At present, Xingchuang Tiandi, Datian Commune, has established cooperative relations with dozens of professional cooperatives in Linhai, with 43 settled enterprises and 5 entrepreneurial tutors, and the annual cumulative sales of agricultural products exceeds 30 million yuan; Xingcheng Tiandi of Anji Mountain Qingchuang Farm has built a 2000-mu modern agriculture and leisure sightseeing demonstration center, a 600-square-meter pioneering office area and a 1500-mu agricultural creation base. Large agricultural enterprises such as Linhai Wuyanchun Tea Professional Cooperative and Linhai Yiguo Fruit Professional Cooperative in the park have successfully driven the average income of surrounding farmers to increase by 5000 yuan.
Taking the mechanism construction as the support point, we should make a good overall plan and make a first move.
Pu Zhancong is a “senior” researcher with 12 years’ experience as a science and technology correspondent. He has been sinking to Yongquan Town, Kuocang Town, Yanjiang Town and other towns in Linhai for a long time to carry out scientific and technological services. He is from Zhejiang Citrus Research Institute, giving full play to his professional advantages, and comprehensively promoting organic fertilizer instead of chemical fertilizer technology, green and efficient fertilization technology and green prevention and control technology of citrus diseases and insect pests, so as to protect the development of citrus industry.
Other members of the team of science and technology commissioners are also “products” of precise matching. Matching supply and demand, accurate selection, is the construction direction of the special commissioners team that Linhai has always adhered to. For this reason, Linhai has established a special commissioners expert database with relevant functional departments, scientific research institutions and college experts as the main body, and investigated the technical requirements of 19 towns and streets to ensure that the special expertise of special commissioners matches the needs of towns and streets. Up to now, Linhai City has achieved the full coverage of all town and street science and technology commissioners, and has deployed eight batches of 130 science and technology commissioners in total, releasing the scientific and technological strength in the countryside. All the commissioners are experts in their respective fields, and the matching degree of professional expertise and demand is over 90%.
“We shouted directly in the group,’ Take a shot’, and experts answered technical problems for us. It’s so convenient!” A farmer in Yongquan Town said. In order to smooth the channels, Linhai has made great efforts in the information communication mechanism, and organized the establishment of a WeChat group for science and technology correspondents to contact towns, streets and clients, so that the correspondents can share agricultural practical technical knowledge and broadcast agricultural weather online in time, and “feel the pulse” for agricultural production. At the same time, it is a key task for each science and technology correspondent to contact more than five agricultural enterprises and farmers’ professional cooperatives, and it is required to do a good job in training. In the past two years, the lecturers, mainly science and technology commissioners, have carried out more than 100 training, lectures and other activities in Linhai City, distributed more than 6,000 technical and publicity materials, and participated in training for tens of thousands of farmers.
While expanding the service coverage, Linhai also set up 10 service teams, such as tea industry upgrading, agricultural meteorology and fruit tree cultivation technology, and organic agriculture, according to the industrial needs of towns and streets, and jointly set up five service teams, including infrastructure, agricultural technology, health, science and technology going to the countryside, and policy and regulation consultation, with rural work instructors, to carry out cross-regional group services and build a service model of the whole industrial chain.
In terms of daily management, Linhai Science and Technology Bureau has always been aiming at being the “maiden” and “back-backer” of a science and technology correspondent, organizing work exchange meetings from time to time, jointly studying and discussing daily work, visiting the correspondent and the projects he is implementing, and working together to solve problems encountered in his work, so as to motivate the correspondent to apply “scientific and technological strength” and “service strength” in place.
With the deepening of the work of science and technology commissioners, the service fields and functions are further expanded, which puts forward higher requirements for strengthening the management of science and technology commissioners. “In the next step, we will build a long-term incentive mechanism, and strive to create a model of science and technology commissioners with’ up-down interaction and integrated operation’, so that science and technology commissioners can play a greater role in rural revitalization and contribute to the first power of science and technology in building a demonstration zone for common prosperity in Zhejiang.” Wang Ping, director of Linhai Science and Technology Bureau, said.
