棉花繁殖地裹往往有这样的现象:有的植株早期生长的特别茂盛健壮,因而发育也早;相邻的植株却有时生长的缓慢而孱弱,生育环境相同,管理方法相同为什么生长势有强有弱呢?原因只能向棉花本身和环境的关系去探求。如种籽的成熟度,种籽是否饱满,发芽是否良好,出苗有没有受到机械的障碍等等。这种现象的存在说明棉花早期的生长势是有差别的,到生长后期这种差别从表面上看来似乎已经消灭(特别表现在株高上),但早期生长势的强弱对于成
There are often such phenomena in cotton breeding habitat: some plants are particularly vigorous and vigorous in their early growth, and therefore develop early. Adjacent plants sometimes grow slowly and weakly, have the same growth environment, and have the same management practices. Why growth is strong Weak? The reason can only explore the relationship between the cotton itself and the environment. Such as seed maturity, seed fullness, germination is good, there is no emergence of mechanical barriers and so on. The existence of this phenomenon shows that there is a difference in the early growth potential of cotton. To the late growth stage, this difference seems to have been eliminated on the surface (especially on the plant height), but the strength of early growth potential
