在棉花成熟前适时喷施乙烯利,不仅能使棉花提早成熟、早腾茬口,而且还可以提高霜前花率、增加籽棉的产量。其具体施用技术要点如下: 1、棉田类型:对各类晚熟棉田和需要赶种其他作物的棉田,可用乙烯利催熟。对于可以正常吐絮及留种的棉田,则不宜采用乙烯利催熟。
In the cotton before the timely spraying of ethephon, cotton can not only make early maturity, early Teng crop, but also can increase the frost before flowering rate, increase the yield of seed cotton. The specific application of technical points are as follows: 1, the type of cotton field: all kinds of late-maturing cotton fields and cotton fields need to catch other crops, available ethephon ripening. For cotton bolls that can be normally flocculent and retained, it is not advisable to use ethephon for ripening.
