1982年全省麦棉套种(以下简称麦套棉)自然面积达392.87万亩.这类棉田在棉麦共生期间,由于争水、争肥、争光矛盾突出,缺苗、迟发、贪青晚熟严重,影响棉花产量品质的提高.为解决这一问题,我们近年大力推广营养钵育苗移栽技术,初步缓和了这些矛盾,获得麦棉较好产量.1982年又进一步对麦套棉进行地膜复盖栽培试验示范.据周口、开封两地区和新乡、民权、睢县统计,麦套棉地膜示范4686亩.现将试验示范初步结果报告如下:
In 1982, the province’s wheat-wheat intercropping (hereinafter referred to as wheat-cotton) natural area of 39287800 acres.This cotton field in the symbiosis of cotton and wheat, due to water, fight fat, highlight the contradiction between the prominent, lack of seedlings, delayed, late greyish green Seriously affecting the cotton yield and quality improvement.In order to solve this problem, we vigorously promote nutrition bowl seedling transplanting technology in the recent years, initially to ease these contradictions, to obtain a better yield of wheat and cotton.In 1982 and further wheat bran cotton membrane complex Cover cultivation test demonstration.According to Zhoukou, Kaifeng and Xinxiang two areas, civil rights, Shexian statistics, wheat sets of plastic film demonstration 4686 acres.Pilot demonstration demonstration results are as follows:
