近年来,由于自然条件和耕作制度的改变,出现了相当一部分晚播棉和夏播棉,使棉铃不能在霜前正常成熟吐絮,影响了品质和产量。生产实践证明,棉田喷施乙烯利,可以加速棉铃成熟、开裂、吐絮,提高棉花品级,增加霜前花量,可收到增产增收的效果。
In recent years, due to the change of natural conditions and cultivation system, a considerable part of late-sowing cotton and summer sowing cotton have appeared, so that cotton bolls can not normally mature and swill before frost, affecting quality and yield. Production practice shows that the spraying of ethephon cotton, cotton boll can accelerate the aging, cracking, bolting flocculation, improve cotton grade, increase the amount of frost before, can receive the effect of increasing production and income.
