不用一滴农药,仅凭纯物理方法,就能根治危害蔬菜生产至烈的韭蛆难题;在告别农药残留的同时,还有利于韭菜增产,且大幅降低菜农生产成本。近日,中国农科院蔬菜花卉所研究员张友军领衔团队研发的“日晒高温覆膜”防治韭蛆新技术,获得示范农户和包括两位院士在内的验收专家的交口称赞。蔬菜农药残留一直是公众关注的食品安全焦点议题,其中,韭菜因细叶、 Without a drop of pesticides, purely physical methods can cure the problem of leek maggots that endanger the production of vegetables. In bidding farewell to pesticide residues, it is also beneficial to increase yield of leeks and greatly reduce vegetable farmers' production costs. Recently, researcher Zhang Youjun, a researcher at the Chinese Academy of Agricultural Science and Vegetable Flower, led the team to develop the “sun-cured high-temperature coating” technology to prevent and cure leek maggots and received praise from the model farmers and acceptance experts including two academicians. Pesticide residues in vegetables has always been the focus of food safety issues of public concern, among them, leeks due to fine leaves,
