| 摘 要： | 在10月中下旬对鄱阳湖棉区棉花喷施3种不同的脱叶催熟剂,研究了其应用效果。结果表明:喷施噻苯隆+乙烯利的脱叶效果最明显,且脱叶率随着噻苯隆浓度的增加而提高;单施乙烯利的脱叶效果不明显;不同处理对棉花的催熟效果均不明显,以喷施750 g/hm2噻苯隆+2250 mL/hm2乙烯利处理的相对较好;喷施脱叶催熟剂对棉花的单铃重和衣分没有明显的影响,对纤维品质的影响有待进一步研究。

| Abstract: | Three different cotton defoliation ripeners were sprayed in the mid and late October in the Poyang Lake cotton area,and their applied effects were studied.The results showed that spraying Thidiazuron plus Ethephon had the most significant defoliation effect,and the defoliation rate increased with the increase of Thidiazuron concentration.The defoliation effect of singly spraying Ethephon was not obvious.The effects of all treatments on the ripening of cotton were not obvious,but that of spraying 750 g/hm2 Thidiazuron + 2250 mL/hm2 Ethephon was the best.The defoliant ripeners had no significant influence on cotton boll weight and lint percentage,and their effects on fiber quality required further research. |
