棉花使用乙烯利能提早吐絮8～15天,加速棉铃开裂,催熟效果明显,青铃降低20％左右,品质提高0.5～1级。使用技术要掌握三点: 1.使用对象:乙烯利适用于棉花后期生长过旺的高产田;晚发迟熟的棉田;麦棉套种春种棉田;麦棉连作的夏棉田。因为这些棉田霜期一到,不少棉铃不能及时成熟,如不催熟,常得不到高产和影响两熟棉田的下茬种植。
The use of ethephon cotton boll early 8 to 15 days to speed up cotton boll cracking, ripening effect is obvious, Qingling reduce about 20%, the quality of 0.5 to 1 level. The use of technology to master the three points: 1. The object of use: ethephon is suitable for late growth over cotton high yield field of cotton; late late maturing cotton fields; wheat cotton intercropping cotton spring; wheat cotton intercropping summer cotton. Because these cotton fields frost period, many cotton bolls can not be mature in time, if not ripening, often do not get high yield and affect the two crops of cotton crop cultivation.
