Due to the long-term vegetative propagation of strawberries, the virus will continue to accumulate in the body, resulting in the weakened growth potential of the plant, the dwarf of the individual, the smaller leaves, the yellowing of the leaves, the smaller fruit, the decrease in yield, and the deterioration of quality, causing huge losses. "The use of strawberry virus-free seedlings in production is one of the effective ways to solve these problems, but due to technical and cost reasons, the current popularity of strawberry virus-free seedlings in China is not high, less than 5% of the planting area." Dr. Xue Wanxin, general manager of Shanghai Yuanyi Seedling and Shanghai Shumei Seed Industry, said.
"Many scientific research units and enterprises in China are also engaged in the research of strawberry virus-free seedlings, but the actual application ratio in production is not high. There is still a long way to go from selecting the source of the variety, peeling from the shoot tip, tissue culture and rapid propagation, rooting, and others. How to maintain the original species and high-quality characteristics of the variety in tissue culture and rapid propagation is also a big challenge. From the tissue culture room to the domestication of the greenhouse to the formal large-scale commercial production, it also takes a long time, and each link has a key point of technical control. It is precisely because of this series of difficulties that the final price of virus-free seedlings in the hands of farmers is not low, basically 1.5-2.0 RMB per seedling. High cost has also become one of the factors hindering the popularization of strawberry virus-free seedlings. Yuanyi Seedlings, a relatively strong seedling factory manufacturer in China, hope to continuously improve tissue culture technology, expand the scale, reduce the final price of seedlings, and benefit more farmers. "
"We began to engage in the large-scale breeding and promotion of strawberry virus-free seedlings in 2016 and established the Qingpu Baihe Strawberry R&D Center with a number of units to jointly carry out research on breeding technology and facility cultivation technology of strawberry seedlings. Through the integration and upgrading of the entire industry chain, end-to-end closed-loop management has been achieved from the introduction and development of new varieties to fresh fruit sales and strawberry processing. At the same time, the company aims to become the strawberry cultural park with the most picking experience in Shanghai, actively expand new forms of agriculture, and make the regional brand "Baihe Strawberry" bigger and stronger. The company's "Shumei" brand, strawberry, has passed the green food certification and has won awards in national and Shanghai evaluation activities many times.
"China's strawberry varieties are relatively concentrated, and the three varieties of sweet Charlie, Hongyan, and Zhangji account for more than 60% of the production area. In Shanghai, "Hongyan" and "Zhangji" are the two most important strawberry varieties, accounting for 98% of the market. In recent years, the cultivation methods of strawberries have gradually diversified, and elevated cultivation has gradually emerged. Combined with picking and sightseeing, it can effectively increase the income of growers. However, the input cost of elevated cultivation is relatively high. Only by comprehensively improving the quality of strawberry seedlings, water and fertilizer management technology, pest management, environmental condition control, and other factors can we maximize profits.
