河南棉花种植制度,正处在由传统的单作一年一熟制趋向粮(油)棉间套,复种一年两熟制发展.当前,除仍以一熟制棉田为主外,麦棉套种发展较快,据1981年不完全统计,全省麦棉套种面积达到280万亩左右,约占棉田总面积的三分之一.还有油菜茬棉花、麦茬棉花和箭等豌豆棉花等.特别是中棉所10号的育成,麦茬棉花更有大发展的趋势.因此,根据河南自然气候特点,探讨棉田合理的耕作制度,对进一步发展棉花生产,具有重要意义.
Henan cotton planting system, is in the traditional one-year-a-year system of grain (oil) cotton intercropping system, double cropping system developed a year.Currently, in addition to still a single system of cotton-based outside, cotton cover According to incomplete statistics in 1981, the area of wheat and cotton intercropping in the province has reached about 2.8 million mu, accounting for about one third of the total area of the cotton field. There are also rape stubble cotton, wheat stubble cotton and arrowhead pea cotton and so on. In particular, the development of Cotabato No.10 and the growth of wheat stubble have a tendency of great development.Therefore, it is of great significance to explore the reasonable farming system of cotton field according to the natural climate characteristics of Henan Province, which is of great significance to the further development of cotton production.
