试验是在烟草花叶病流行普遍、危害严重的地区,围绕麦烟套种,防治烟草花叶病的效果进行的。着重研究移栽期、种植方式与发病的关系。试验得出:1.根据麦烟套种能显著减轻烟草花叶病危害的原因,他们采用防治介体蚜虫迁飞传毒,选用前期生长快的品种和提早移栽期,加强田间管理促进烟株早发等综合栽培技术,使烟株在花叶病大流行之前长成更多的叶片就能有效地减轻花叶病的危害。2.麦烟套种是防治花叶病的重要措施,有条件的麦烟区应因地制宜积极示范推广。 The test was conducted in areas where tobacco mosaic disease is prevalent and endangered. It is conducted around the interception of wheat and tobacco and the prevention and control of tobacco mosaic disease. Emphasis will be placed on the relationship between transplanting, planting methods and incidence. The results showed as follows: 1. According to the reasons why tobacco seedlings could significantly reduce the risk of tobacco mosaic disease, they used the aphids to control the migration of insects and flee the virus, selected varieties with fast growth and early transplanting period, and strengthened field management to promote tobacco plant Early and other comprehensive cultivation techniques, so that tobacco plants grow into more leaves before the Mosaic pandemic can effectively reduce the mosaic disease. 2. Interplanting wheat and tobacco is an important measure to prevent and control mosaic disease. The qualified wheat smoke area should be actively demonstrated and popularized according to local conditions.
