南阳盆地是全国著名的优质商品棉基地之一,常年植棉面积180万亩左右。“八五”期间发展到250万亩,麦棉套种是主要栽培制度。棉花育苗移栽的推广,较好地解决了棉花出苗难、全苗难和迟发晚熟的问题,但是多数苗床高脚弱苗,移栽后成活率低,缓苗期长,致使大面积棉田密度下滑,稀植大棵,迟发晚熟等,不仅制约了移栽棉早发高产优势,而且由于棉花腾茬晚,麦播粗放,
Nanyang basin is one of the famous high-quality commodity cotton base, perennial cotton area of about 180 acres. During the “Eighth Five-Year Plan” period, it has developed to 2.5 million mu and the wheat-cotton intercropping system is the main cultivation system. Cotton seedling transplanting promotion, a good solution to the problem of cotton seedling difficult, late seedling difficult and delayed late maturity, but most of the seedlings of high and weak seedlings, low survival rate after transplanting, Huanmiao period, resulting in large areas of cotton fields Density decline, sparse planting big trees, delayed late ripening, not only restricts the transplanting cotton early high yield advantage, but also because of cotton stubble late, broadcasted,
