摘要
以萘二甲酸酐作解毒剂,分别添加赤霉酸、复硝钾、尿素+磷酸二氢钾、芸苔素内酯对硝磺草酮中毒棉花进行灌根处理。试验结果表明:灌根处理能有效减少棉花枯叶率和蕾铃脱落率,进而显著补救棉花产量损失,其中萘二甲酸酐+芸苔素内酯效果最好,药后60天的枯叶率和蕾铃脱落率分别比对照减少23.1和32.6个百分点,籽棉产量比对照增加112.3%,具有很好的推广应用价值。
The study took naphthalene anhydride as antidote,respectively adding gibberellic acid,potassium nitrate,po-tassium dihydrogen phosphate,urea ＋brassinolide on mesotrione poisoning cotton root irrigation.The results showed that：the root irrigation treatment can effectively reduce the rate of cotton leaves and boll abscission rate,and it was significant in reme-dying the loss of cotton yield,naphthalene anhydride ＋ brassinolide had the best effect,60 days afterdrug ,the leaves and the rate of abscission were reduced by 23.1 and 32.6 percentage points,Seed cotton yield increased 112.3% than CK,and had good popularization and application value.
