种子包衣是目前国外广泛应用的防治作物苗期病害的新技术,我所研究试用国产农药、粘着剂、辅助剂进行棉花种子包衣以及农药、肥料、微量元素等复合种子包衣方法,处理的棉子药衣附着均匀,储存搬运药皮不脱落,不影响种子吸水发芽和出苗,无药害。棉种播量由每亩15斤减少到5斤,在接种了立枯菌发病严重的棉田,棉株发病率由71%压缩到10%左右,防治效果达90%左右,对缩小发病区,保护新棉区有重要意 Seed coating is currently widely used in foreign countries to prevent crop seedling disease new technology, I study the trial of domestic pesticides, adhesives, adjuvants for cotton seed coating and pesticide, fertilizer, trace elements and other composite seed coating method, treatment Of the cotton seed coat attached evenly, do not fall off the storage and handling of the drug does not affect the seed germination and emergence of water, no injury. Cotton seed sowing rate reduced from 15 pounds per acre to 5 pounds, inoculated with the serious disease of cotton seedlings of cotton, the incidence of cotton from 71% compressed to about 10%, control effect of 90%, to reduce the incidence of disease area, It is important to protect the new cotton area
