摘　　要：以湘春2701为试验材料,对乙烯利、敌草快、噻苯隆3种药剂不同稀释倍数处理对南方春大豆落叶的影响进行了研究,结果表明:大豆喷施敌草快的脱叶率高于喷施乙烯利和噻苯隆的,敌草快与乙烯利均能作为大豆的落叶剂,噻苯隆处理效果不明显;敌草快具有快速催枯的效果,处理后大豆叶片和叶柄迅速枯黄,推荐使用稀释倍数为100~400倍液;乙烯利处理后的落叶效果稍缓,推荐使用稀释倍数为100~400倍液。Xiangchun 2701 was used as experimental material to study the effects of ethephon,diquat and thidiazuron on the defoliation of spring soybean in southern China.The results showed that the defoliation rate of soybean leaves sprayed with diquat was higher than that with ethephon and thidiazuron.Diquat and ethephon could be used as defoliant for soybean,while the effect of thidiazuron was not significant.Diquat has the effect of causing the soybean leaves and petioles withered rapidly,it is recommended the dilution ratio of 100-400 times.Ethephon takes effect slower than diquat,the dilution ratio of 100-400 times is recommended for it.
