为降低烟草花叶病的发生率 ,进行了 4种不同育苗方式对比试验。结果表明 ,营养杯直播育苗、消毒营养土营养袋假植育苗和穴内营养土直生苗的烟草花叶病病指分别比普通营养袋假植苗 (对照 )下降87.97%、 70 .3 9%和 59.61 %,达极显著和显著水平 ;其农艺性状、产量、质量也都优于对照。进一步完善后可以推广应用 In order to reduce the incidence of tobacco mosaic disease, 4 different breeding methods were compared. The results showed that the disease index of tobacco mosaic disease of nutrition cup direct seeding seedlings, sterilized nutrition soil nursery bags and tobacco inflorescence soil direct seedlings decreased by 87.97%, 70.39% and 59.61% respectively, reaching extremely significant and significant level. The agronomic traits, yield and quality were also better than the control. After further improvement can promote the application
