粮棉两熟地区,夺取粮棉双丰收,存在着争季节、争肥料、争劳力的矛盾。棉花常因迟熟不能达到稳产高产,同时影响冬作不能适时播种。为了探索棉花早熟增产的栽培技术,我们根据省委对棉花生产提出的两个150(即150天的生育期和150斤皮棉产量)的要求,于1972年开始由工人、教师、学员组成三结合试验小组,进行了棉花不同密度的比较试验,现将结果初报如下: 一、基本情况试验分两部分: 1、不同密度比较:四个处理,两次重复,小区净面积六厘。四个处理是: ①20,000 株/亩等行行距1.0尺株距0.3尺②10,000 株/亩等行行距1.5尺株距0.4尺
Two areas of grain and cotton to win the bumper harvest of grain and cotton, there is the fight season, competition for fertilizer, fighting labor conflicts. Often due to late maturity cotton can not be stable and high yield, affecting the winter can not be timely sowing. In order to explore the cultivation techniques of early maturity cotton production, according to the requirements of two provincial 150 (ie 150-day growth period and 150 kg lint yield) cotton production proposed by the provincial committee, we started in 1972 with three combinations of workers, teachers and students The test group carried out a comparative test of cotton density. The results are as follows: First, the basic situation of the test is divided into two parts: 1, different density comparison: four treatment, two repetitions, the net area of six per cent. The four treatments are as follows: ①20,000 plants / mu, etc. Line spacing 1.0 ft. Distance 0.3 ft. ② 10,000 ft. / Acre.
