摘　　要：通过研究200 g/L敌草快二溴盐可溶液剂对马铃薯催枯的应用效果,发现敌草快作为催枯剂具有快速和高效等特点,而且对马铃薯增产显著,施药量为有效成分900、1 200、1 500 g/hm^2时,药后7 d马铃薯产量分别增加2.1%、8.8%和8.9%。另外,检测发现敌草快在马铃薯中为零残留,具有高度安全性。由此可见,敌草快在对马铃薯催枯方面极具推广价值和应用前景。This paper aims to test the application effect of 200 SL diquat dibromide to dehydrate of potato in pot experiment.The results showed that the effect of diquat dibromide is fast and efficient, also can increase potato production as an accelerating agent. Diquat dibromide of 900, 1 200, 1 500 g a.i./hm^2 can improve the yield of potato by 2.1%, 8.8% and 8.9%respectively 7 d after treatments. In addition, zero residue of diquat in potato after treatments means that diquat dibromide is very safe. Thus, it can be seen that diquat dibromide has excellent popularization value and application prospect in potato planting.
