摘要: 为明确防雹网对烤烟主要病虫害的防治效果,本研究于2019年在河北省蔚县烟区3个试验田架设防雹网进行调查研究.结果显示,架设防雹网对烟青虫的发生及为害影响不大,但对烟蚜防效明显,同时可有效减轻烟蚜传播病毒病的发生,特别是马铃薯Y病毒(PVY)和黄瓜花叶病毒(CMV).因此,防雹网保护栽培技术的推广应用可有效减轻病虫为害,具有很大的应用前景.Abstract: In order to clarify the control effect of hail-proof net on the main diseases and pests of flue-cured tobacco, hail-proof nets were set up in three experimental fields in Yu County Hebei Province in 2019 for investigation and research. The results showed that the hail-proof net had little effect on the occurrence and harm of the budworm, but it had obvious control effect on aphids, and could effectively reduce the occurrence of aphid-transmitted virus diseases, especially tobacco potato virus(PVY)and cucumber mosaic virus(CMV). Therefore, the popularization and application of hail-proof net protection cultivation technology could effectively reduce the harm of diseases and pests, which has a great application prospect.
