棉花红叶茎枯病是棉花中、后期的主要病害之一。1967年上海植物生理研究所深入实践调查研究,找出了红叶茎枯病的发病原因和有效防治措施。多年来,广大贫下中农的防治实践进一步证明,只要防治及时,重病之年同样能够夺得棉花的好收成.例如湖北省孝感县肖港公社丰胜大队1975年700多亩棉花,除施用农家肥外,发病初期还增施了氯化钾6,200斤,取得了显著的防病增产效果,1975年平均亩产皮棉195斤,比发病较重的1972年平均亩产107.9斤增产80%。
Cotton leaf blight is one of the major diseases in cotton in the late stage. In 1967, Shanghai Institute of Plant Physiology conducted in-depth investigation and research to find out the causes of leaf blight and effective control measures. Over the years, the prevention and control of the majority of poor and middle peasants further proved that as long as the timely prevention and treatment of serious illness can also get a good harvest of cotton .For example, Xiaogan County, Hubei Province Xiao Gang commune Fengsheng brigade 700 acres of cotton in 1975, except for the use of manure In addition, during the early stages of disease, potassium chloride 6,200 kg was also added. Significant effects of disease prevention and yield increase were achieved. In 1975, the average yield of lint was 195 kg, an increase of 80% over the previous year.
