It's potato breeding time again, and in the potato planting base of an agricultural enterprise in Fuzhou, Guo Yuchun flips the seed potato and teaches green and high-yield cultivation techniques to growers on the spot.
Guo Yuchun is an associate professor at the Department of Agronomy, Fujian Agriculture and Forestry University, specializing in the study of high yield and molecular ecology of rice potatoes. As a science and technology commissioner, he guides the breeding technology and green high-yield cultivation technology of potato detoxified seed potatoes and sweet potato detoxified seedlings in enterprises, improves the quality and yield of breeding, guides large potato growers contacted by enterprises to carry out efficient green cultivation, and provides assistance for farmers to increase production and income.
According to the person in charge of the enterprise, the seed potato and seedlings of ordinary potatoes and sweet potatoes have weak resistance to diseases and insect pests, and the mortality rate of plants can be as high as 70% or even harvest, which brings great risks to the income of growers.

"We continue to optimize and improve, and the yield of potato seed potatoes bred by detoxification technology can be increased by 1,000 catties per mu, and the quality of the potatoes grown has also been improved." Guo Yuchun introduced. In the 20 acres of sweet potato detoxification seedling breeding greenhouse established in the Changting base of the enterprise, he helped the enterprise to cut the seedlings reasonably, and the average mu could be cut 4000 more qualified sweet potato seedlings than the original, 0.3 yuan per plant, and 1200 yuan per mu.
"With the technical support and guidance of experts, our breeding of potato seed potatoes has increased from the original 1.5 yuan / kg to 1.8 yuan / kg, which is more popular in the market, and many growers give priority to our seed potatoes." The head of the enterprise said with a smile. In 2020, when Fujian suffered from exceptionally large frost damage, the science and technology commissioner also provided professional and technical guidance for the first time to help growers smoothly survive natural disasters and achieve less production and no harvest reduction.
In recent years, Fuzhou High-tech Zone has actively responded to the work deployment of Fujian Province and Fuzhou City, carried out the implementation of the science and technology commissioner system, relying on the scientific research and talent advantages of universities in university towns and provincial capital scientific research institutes, and selected science and technology commissioners to provide technical support and assistance to the production line, and opened up the "last kilometer" of the technology landing industry.
According to the relevant person in charge of the Science and Technology Bureau of Fuzhou High-tech Zone, a total of 96 science and technology commissioners will be selected to connect with the recipient units, townships and administrative villages in 2020. "We have effectively docked production demand and 'intellectual supply' through platforms such as the Fuzhou Technology Transfer Public Service Platform and Fumin Yunka, helping the industry solve technical problems and truly combining production, education and research."
Fuzhou High-tech Zone not only has science and technology commissioners, but also "science and technology missions". In 2019, Huang Ying, a teacher at the College of Food Science of Fujian Agriculture and Forestry University, Luo Lijin of Fujian Institute of Microbiology, Luo Nianbei of Fuzhou University, Xu Zhiyong of Fujian Yuandao Institute of Ecology and Environment, and other 7 scholars formed an "expert group" to provide technical support for a fresh food production enterprise mainly engaged in cold and fresh meat processing.
Mission members have different research directions, including providing guidance on the farming environment in upstream farms, providing technical support for preservation in the processing process, and doing business analysis and management research. "Through multidisciplinary intersection, we can connect with each other and provide enterprises with full-chain technical guidance for breeding, processing, logistics and sales." Huang Ying said.
Last year, after visiting the workshop site of the above-mentioned fresh food production enterprises many times, Huang Ying guided the enterprise to build a 1,000-square-meter low-temperature operation workshop and 5 cold storage, and at the same time helped the workshop to select equipment and upgrade production lines, select advanced equipment at home and abroad, and realize intelligent and standardized production transformation.
The freshness of fresh products has an important impact on the transportation, sales and other links of fresh products. To this end, the team compared and analyzed the influence of different filling gas ratios on the quality of cold fresh meat in modified gas packaging for the modified atmosphere packaging of special livestock and poultry products such as Datian black pig, Minqing hairy foot chicken, Fujian black rabbit, Putian black duck, etc., and finally selected the appropriate gas proportion of various cold fresh meat. The optimized modified atmosphere preservation process extends the shelf life of cold fresh meat, so that the company's preservation technology can keep up with the first-class level at home and abroad.
Luo Nianbei, Xu Zhiyong, etc. gave full play to their professional advantages and guided the fresh food production enterprise to establish a logistics distribution service system and big data analysis, etc., to improve the production efficiency and production capacity of the enterprise, to provide a stable supply of fresh cut meat products for local supermarkets, and to deeply integrate new retail formats, greatly expanding sales channels. In 2020, the fresh food production enterprise will achieve an annual output value of nearly 70 million yuan, drive 4 upstream livestock and poultry breeding enterprises and cooperatives, help 30 farmers through industry drive, and provide more than 40 jobs for local industrial farmers.
