麦后移栽棉花由于季节紧,往往移栽质量较差,“蹲苗”时间长,迟发少结,迟熟低产,限制了麦后移栽棉的发展。近几年,使用机耕与人工相结合的移栽方法,虽缓和了农活集中与季节紧张的矛盾,但灌水或遇大雨土壤板结,多僵苗,难以达到早发早熟高产的要求。 1982年我们在常阴沙农场进行了棉花大面积麦后板茬开沟移栽(“少耕”法)试验。取
Transplanting cotton after wheat due to the season is tight, often poor quality transplanting, “Dunmiao” a long time, late less knot, late maturity and low yield, limiting the development of wheat transplanting cotton. In recent years, the transplanting method using the combination of mechanization and manpower has alleviated the contradiction between agricultural concentration and seasonal stress. However, it is difficult to meet the requirement of early maturity and high yield when irrigating or in heavy rainfall and soil compaction and more seedlings. In 1982, we carried out a large-area wheat transplanting (“tillage”) trial of wheat stubble in the Changyin Sha Farm. take
