为摆脱北京地区种植绿叶蔬菜产量低的困境,叶类蔬菜产业技术体系北京市创新团队首席专家、北京农学院教授范双喜带领其研究团队联合攻关,破解了生菜高产安全技术,选育出4个适于北京种植的优质高产生菜品种,建立并推广无公害生产和有机生产技术体系,此技术将实现生菜周年栽培。这意味着,今后北京市场上蔬菜自供率将大大提高,市民能够在市场上买到便宜、新鲜、安全的本地产生菜。针对北京蔬菜市场对生菜需求的亟需,该团队先后培育出适合北京及周边区域种植的优质生菜品
In order to get rid of the low output of green leafy vegetables in Beijing, the technology team of leafy vegetables, chief expert of Beijing Innovation Team and Professor Fan Shuangxiu from Beijing Agricultural College led the research team to jointly tackle the problem of high yield and safety of lettuce and bred 4 Suitable for planting high-quality Beijing varieties of vegetables, establish and promote pollution-free production and organic production technology system, this technology will achieve annual lettuce cultivation. This means that in the future the market for vegetables in Beijing will greatly increase its self-supply rate and citizens will be able to buy cheap, fresh and safe locally-sourced produce on the market. In response to the urgent need for lettuce in the Beijing vegetable market, the team has cultivated quality lettuce suitable for planting in Beijing and the surrounding area
