摘　　要：为探索催枯剂对水稻穗部性状及品质的影响,在水稻收获期,选择敌草快、草甘膦、乙烯利等3种不同化学药剂开展田间催枯脱水效果试验。结果表明,3种药剂在一定程度上均能够加速水稻叶片脱水,降低水稻的田间含水量,其中敌草快效果最好,草甘膦次之,乙烯利最差。所有供试药剂均对水稻安全,对千粒重、产量、品质无显著影响。To explore the effect of dehydrating agent onrice panicle traits and quality,three different chemical agents,including diquat,glyphosate and ethephon,were selected to carry out field withering and dehydration effects experiments at the end of rice maturity.The results showed that the three chemicals could accelerate the dehydration of rice leaves and reduce the field Moisture Content of rice to a certain extent.All the tested agents were safe for rice,and had no significant effect on thousand grain weight,yield and quality.
