摘要
通过田间小区试验,研究鲁西棉区不同脱叶剂在田间应用中的脱叶效果及其对棉花品质和产量的影响。结果表明,喷施噻苯隆+乙烯利(450 g/hm2+1 200 ml/hm2)、噻苯隆·乙烯利悬浮剂(1 800 ml/hm2)不仅能够明显提高霜前花率,且脱叶效果好、纤维品质基本无不利影响,籽棉产量高于清水对照,皮棉产量同清水对照基本相当。
Through field experiments,the application of different defoliant and effects on cotton quality and yield in southern Shandong Province were studied. The results showed that spraying thidiazuron ＋ ethephon（ 450 g / hm^2＋ 1 200 ml / hm^2）,hydrochlorothiazide（ 1 800 ml / hm^2） suspending agent can not only significantly improve the flowering rate before frost,and the leaf removal effect is good,no adverse effects on fiber quality,seed cotton yield was higher than CK,lint yield with water control.
