棉花蕾铃脱落是阻碍棉花达到高产的主要因素。锦州地区一般脱落率在70％左右,甚者达80％以上。影响蕾铃脱落的因子很多,除机械损伤外,生理脱落因子很为复杂。但一般情况田中脱落较重,田边脱落较少。因此,利用边行优势就有很大可能性达到保铃,增产。 Cotton buds fall off is hindered the cotton to achieve the main factor of high yield. Jinzhou area generally shed about 70%, or even more than 80%. There are many factors that affect the shedding of the buds. Apart from the mechanical damage, the physiological shedding factor is very complicated. However, Tanaka generally shedding less, Tanabe shed less. Therefore, there is a great chance of using the edge of the bank to reach the goal of bolting and increasing production.
