摘要
以5种不同剂量剂型的脱叶剂为研究对象,探讨不同脱叶剂在江汉平原的脱叶催熟效果及其对棉花产量的影响。结果表明:在棉花吐絮率约44%时,使用50mg/L噻苯·乙烯利悬浮脱叶剂2700 ml/hm2,对棉花脱叶和吐絮效果最好,霜前花率和实收产量最高。
The study adopted five different dose and dosage forms as thesubject investigated to discuss the ripening effect of defoliation and yield among different cotton defoliant in Jianghan Plain. Results showed that using 50mg/L thiabendazole - ethephon suspended defoliants 2700ml/hm^2 in cotton boll opening rate of about 44 %, there presented not only best defoliation and boll opening effect but also highest prefrost rate and yield.
