作者于1981—1987年,对山西运城、临汾、晋中、晋东南4个地区15个县的棉花烂铃问题进行了调查研究。明确了引起烂铃病以疫病Phytophthora boehmeriae Saw.、红腐Fsa-r~(riummoniliforme) Sheld和红粉Cephalothecium roseum(Link)Corde为主。由疫病引起的烂铃占91.5%,烂铃率与8月中、下旬以后40天内的降雨量呈正相关;果枝节位愈高烂铃率愈低;陆地棉烂铃率高,亚洲棉和草棉抗病,适期播种及早防治蛀铃害虫可降低烂铃率。
In 1981-1987, the author conducted a survey on the problem of cotton bolls in 15 counties in 4 districts of Shanxi Yuncheng, Linfen, Jinzhong and southeast of Shanxi. It is clear that the main cause of the rotten boll diseases is Phytophthora boehmeriae Saw., Rsa-rum (Rummoniliforme) Sheld, and Cephalothecium roseum (Link) Corde. The rotten bolls caused by the disease accounted for 91.5%. The rotten boll rate was positively correlated with the rainfall within 40 days after the middle and late August. The bolls with lower rotting nodes were lower, the rotten boll rate was higher, Diseases, early sowing pests can reduce the rate of bad bell.
