雪菜又名雪里蕻 ,近年病毒病严重发生 ,其病原物为 Tu MV,传播昆虫有翅蚜在夏、秋季 2个转移高峰与雪菜秋、冬季播种育苗期相吻合 ,是主要感病期。应用防虫网覆盖育苗是切断传毒媒介 ,预防病毒病的关键技术。经不同目数、不同颜色的防虫网覆盖育苗试验和示范均取得较好的防病效果 ,防效达 51.2 %～ 73.3% ;增产效果显著 ,还能同时控制苗期其它虫害 Pickled cabbage, also known as seabuckthorn, in recent years, a serious virus disease occurs, the pathogen Tu MV, spread insects winged aphids in summer and autumn 2 transfer peak and pickled autumn, winter seeding seedling phase is consistent, is the main period of susceptibility. Application of insect net cover nursery is to cut off the vector, the key technology to prevent virus disease. Through different mesh numbers, different colors of insect net cover nursery experiment and demonstration have achieved better disease control effect, control effect of 51.2% ~ 73.3%; yield significantly, but also at the same time control other pests
