试验于1984—1986年在湖南常德县进行,获得亩产皮棉113.8公斤优化方案,其理想株型的成铃模式为:密度4000株/亩;单株成铃率27%,单株成铃数16.35个;单株果节数60.6个,总果节24.24万个/亩;单铃重4.34克,衣分38～39%;亩铃数6.54万个。研究发现,栽培条件对棉株群体与个体成铃率和成铃数有明显影响,其中以密度效应最显著,氮素次之,磷、钾肥和花铃肥施氨比亦有一定影响,且各因素之间有一定程度的互作。
The experiment was carried out in Changde County, Hunan Province from 1984 to 1986, obtaining 113.8 kg of optimized plan of lint per mu. The ideal model of boll forming system was: density 4000 plants / mu; the boll number of single plant was 27% 16.35; fruit number per plant 60.6, total fruit section 242,400 / mu; single boll weight 4.34 grams, clothing 38 to 39%; mu bell number 65,400. The results showed that the cultivation conditions significantly affected the bolls and boll numbers of cotton plants, of which density was the most significant, followed by nitrogen, phosphorus and potash, There is some degree of interaction between the various factors.
