烟草黄瓜花叶病(CMV)是我国烟草上最严重的病毒病害,主要由蚜虫传播,试验指出:烟田有翅蚜喜黄色,忌银灰色,利用有翅蚜这种习性,采用银灰色地膜来拒避蚜虫,经1982—1983年大田试验,银灰色地膜避蚜防治 CMV 效果显著,而且稳定。1984年在重病区滕县进行了大面积防治示范,结果指出:应用银灰色地膜覆盖防病效果达88.24—98.17%,效果显著。应用银灰色地膜覆盖平均亩产烟叶346.0斤,不盖膜(对照)平均亩产181.6斤,每斤烟叶均价提高0.194元,每亩增收148.67元,经济效果显著。于6月29—30日在滕县召开的鉴定会认为:应用银灰色地膜避蚜防治 CMV 效果显著,经济效益高,方法简便,可以通过科研成果鉴定,并在烟区大面积推广应用,作为防治 CMV的主要措施。
Tobacco Cucumber Mosaic Disease (CMV) is the most serious virus disease on tobacco in our country. It is mainly spread by aphids. The experiment shows that the winged aphid likes yellow and silver gray, so using the silver-gray film To repel aphids, the field trials of 1982-1983, silver gray plastic film to avoid aphids CMV significant effect, and stable. In 1984, a demonstration of prevention and treatment of large area was carried out in Tengxian County, and the results showed that the application of silver gray plastic film to cover disease prevention reached 88.24-98.17% and the effect was remarkable. The application of silver gray mulch covered an average of 346.0 kg of mu per mu, without membrane (control), with an average of 181.6 kg of mu per mu. The average price of tobacco per mu increased by 0.194 yuan and the yield per mu was 148.67 yuan. The economic effect was remarkable. June 29-30 held in Teng County appraisal will think: the application of silver gray film to avoid aphids CMV significant effect, high economic efficiency, the method is simple, can be identified by scientific research, and popularization and application of tobacco in a large area, as a The main measures to prevent CMV.
