简要介绍了生菜种植中的主要病虫害及其症状。温室大棚生菜生长期较短,采用露天栽培的病虫害防治方案,存在农残超标的风险。基于壳聚糖防治方案的试验,确定了针对不同病害选用的农药品种,编制了温室大棚生菜病虫害防治技术方案,提出了具体的防治措施,为生产符合行业标准《绿色食品 绿叶类蔬菜》(NY/T 743—2020)要求的产品创造了条件。
The main diseases and insect pests in Lactuca sativa L. var. ramosa Hort. planting and symptoms are briefly introduced. The Lactuca sativa L. var. ramosa Hort. in greenhouse has a short growth period, and there is a risk of exceeding the standard of agricultural residues by adopting the pest control scheme of open-air cultivation. Based on the experiment of chitosan control scheme, the pesticide varieties selected for different diseases are determined, the technical scheme for the control of diseases and pests of Lactuca sativa L. var. ramosa Hort. in greenhouse is compiled, and the specific control measures are put forward, which creates conditions for the production of products that meet the requirements of the industrial standard Green food-leaf vegetables (NY/T 743—2020).
