南阳盆地是我省重要商品棉生产基地之一,原棉出口量占全省原棉出口的1/2。90年代以来,随着改革开放和市场经济的发展,小麦和棉花生产得到长足增长,成为南阳地区举足轻重的支柱产业,是种植业中的两大优势作物。但是,当麦棉亩产跨入中产水平后,单产徘徊不前。主要原因是麦棉套种出现了保苗难、全苗难和早发难的问题。栽培上旱薄粗和稀大晚,棉花迟发、晚熟品质差,限制了棉花早熟高产;由于腾茬晚,造成小麦粗种迟播,往往翌春徒长,贪青倒伏,不仅制约了小麦高产,而且影响了棉花的壮苗早
Nanyang Basin is one of the important commodity cotton production bases in our province, with the export volume of raw cotton accounting for one-half of the total export of the province’s cotton. Since the 1990s, with the development of reform and opening up and the development of market economy, wheat and cotton production have grown by a great margin and become Nanyang The pivotal pillar industry in the region is the two dominant crops in the farming industry. However, when the yield per mu of cotton came into the middle class, the yield stagnated. The main reason is the emergence of cotton seedling interplanting difficult, difficult and difficult early seedling problems. Due to the late stubble, resulting in delayed sowing of crude wheat, often Yichun long, greed green lodging, not only restricts the high yield of wheat , But also affected the strong seedling cotton early
