摘要
本试验设计百草枯和乙烯利不同混配比例７个处理，于１９９５年１０月６日在棉花上进行催熟试验。结果表明，每公顷用２０％百草枯水剂６００毫升和４０％乙烯利水剂９００毫升混配对棉花催熟效果最佳，落吐速度、吐絮率，霜前花分别比对照不催熟高５４．４６％、２１．３８％、１４．５１％，幼铃脱落率比用乙烯利单剂下降５２．２０％，亩产比对照提高８．９１％。
ield trials with the mixture of paraquat and ethephon in different ratios to accelerate the ripening of cotton were caried out in 1995.The results showed that the mixture of paraquat 20AE and ethephon 40AE at the dosage of 40ml/666.7m2 and 60ml/666.7m2 respectively gave the best result,the defoliation rate,boll opening rate,quantity of boll opening before frost and yield increased by 54.41%,21.38%,14.51% and 8.91% respectively comparing with control plot and the young boll falling rate decreased by 52.20% comparing with ethephon itself.
