棉花原产热带种亚热带,属短日照作物。在温带生长的棉花,生育期间正处在日照较长的季节,若能给予创造短日照条件,必将缩短光照阶段时间,使生育提前。短日照处理的效应及其能否在生产上应用,是一个值得研究的问题。为此,我们在1983年对豫棉1号和中棉所10号两个品种,进行了不同短日照处理的盆栽试验,1984年又进行短日照处理的田间试验,探讨短日照处理在生
Cotton native tropical subtropical, is a short daylight crop. During the growing season, the cotton growing in temperate zone is in the longer season of sunshine. If it can create short daylight conditions, it will shorten the period of light and advance the birth. The effect of short-day treatment and whether it can be applied in production is a problem worth studying. To this end, in 1983, Yumai 1 and China cotton two varieties of 10 were carried out in different short-term potted plant experiments in 1984 and short-day treatment of field trials to explore the short-day treatment of students
