我县是十万亩以上的重点产棉县,麦棉套种面积常占棉田面积的90％左右。这种耕作制度有三个不足之处:一是小麦播种时要予留棉行,相对缩小了小麦面积,限制了产量的提高;二是棉苗出土后麦棉共生期长,行间荫蔽,光照不足,往往造成高脚苗、丝线苗,苗病普遍,影响棉苗早生快发;三是麦行操作管理不便,难以实现机械化作业。随着农业生产的发展和机械化程度的逐步提高,这种耕作制度必须进行改革。改麦棉套种为麦棉连作,势在必行。
Our county is the key cotton producing county of more than 100,000 mu. The area of wheat-cotton intercropping covers 90% of the total area of the cotton field. This tillage system has three deficiencies: First, cotton planting to be allowed to stay cotton line, a relative reduction of the wheat area, limiting the yield increase; second is the cotton seedlings excavated after a long symbiotic period, shade between the lines, light Insufficient, often result in high seedlings, silk seedlings, Miao disease is common, affecting the rapid emergence of cotton seedlings early; Third, Mai Bank operation and management inconvenience, it is difficult to mechanization operations. With the development of agricultural production and the gradual increase in the degree of mechanization, this farming system must be reformed. Replacing wheat with wheat cotton intercropping, it is imperative.
