万株棉由于密度高,空间小,棉株之间相互争光争肥的矛盾容易激化,在蕾期就出现“横向控、纵向窜”的长相长势,如不加以控制,就会严重影响中、下部果枝的正常现蕾和开花结铃。因此,必须解决高密度容易引起光照不足的问题,协调好营养生长与生 Due to its high density and small space, ten thousand strains of cotton are likely to intensify the conflicts between themselves and their competitors. In the budding period, the appearance of “horizontal control and vertical migration” appears. If not controlled, The lower branch of the normal budding and flowering bell. Therefore, it is necessary to solve the problem that high density can easily cause insufficient light and coordinate the growth of nutrition and health
