摘　　要：为降低烟株发病率和病害给烟叶造成的产质量下降、经济效益下降等影响,以常规无防虫网育苗棚为对照,在烤烟育苗播种前,选择一栋育苗棚在上、下两处放风口安装防虫网作为试验苗棚,烟苗成苗后,所育烟苗在大田开展移栽试验,对比研究烤烟大田不同生育期发病率、烤后烟叶外观质量和经济学性状,分析烤烟育苗棚应用防虫网防控效果。结果:与常规无防虫网育苗棚相比,防虫网所育烟苗移栽后在还苗期、伸根期、旺长期、成熟期发病率显著下降,烤后烟叶外观质量好,产质量和亩产值更高。育苗棚应用防虫网绿色防控效果显著,在烟叶生产育苗环节具有一定的推广应用价值。In order to reduce the incidence rate of tobacco plants and the impact of diseases on the yield,quality and economic benefits of tobacco leaves,the conventional non insect net nursery shed was used as a control.Before the planting of flue-cured tobacco seedlings,a nursery shed was selected to install insect net at the upper and lower air outlets as a trial nursery shed.After the tobacco seedlings mature,the transplanted seedlings were carried out in the field to compare the incidence rate,analyzed the appearance quality and economic characteristics of cured tobacco leaves,and evaluated the effectiveness of applying insect control nets in tobacco seedling sheds.Results:Compared with the conventional seedling rearing shed without pest control net,the incidence rate of tobacco seedlings raised with pest control net after transplanting was significantly reduced at the seedling returning stage,root extension stage,vigorous growth stage and mature stage,and the appearance quality of flue-cured tobacco leaves was good,and the yield and quality and output value per mu were higher.The application of insect prevention nets in seedling sheds has significant green prevention and control effects,and has certain promotion and application value in tobacco production and seedling cultivation.
