我县自1982年试种中棉十号夏棉获得成功后,夏棉面积迅速扩大,到1984年即达到67万亩,亩产小麦250～400公斤,皮棉35～55公斤的较好收成。初步解决了粮、棉争地及吃饭、化钱的矛盾。即使在棉花生产处于低潮的1985、1986两年夏棉面积仍达40万亩左右,占棉田总面积42.6％。1982年以来我们对夏棉主要病虫进行了观察,并和春棉上病虫做了比较,改进了某些防治措施。
Since the successful trial of Zhongmian No.10 summer cotton in 1982, the area of summer cotton has expanded rapidly. By 1984, it reached 670,000 mu, with a yield of 250-400 kg per mu of wheat and 35-55 kg of cotton lint. The initial solution to the conflict between food and cotton, food and money. Even in the cotton production at a low ebb of 1985,1986 two-year summer cotton area is still up to 400000 acres, accounting for 42.6% of the total cotton field. Since 1982, we have observed the main pests and diseases of summer cotton and compared them with those on spring cotton, and improved some control measures.
