近年我县烤烟花叶病越来越严重 ,导致有的减产 ,甚至绝收。为寻找控制该病促进烟叶生长的理想制剂 ,2 0 0 0年我们对保得生物肥 (烟草专用型 )防病促生效果进行了专题试验。1　材料与方法供试烟叶品种为Ｋ32 6 ,3月 2 0日移栽 ,单位面积 (6 6 7ｍ2 ,下同 )移栽密度 1 2 0 0株。 In recent years, our county flue-cured tobacco mosaic disease more and more serious, resulting in some production cuts, or even absolute. In order to find out the ideal preparation to control the disease and promote the growth of tobacco leaves, we conducted a special trial on the preventive and curative effects of Baode Biological Fertilizer (Tobacco Type) in 2000. MATERIALS AND METHODS The tested tobacco varieties were K32 6, which were transplanted on the 20th of March. The transplanting density per unit area (6 6 7m 2) was 12 000.
