摘    要:
草甘膦是一种灭生性除草剂,具有高效、用量少、低毒、杀草谱广、使用时期灵活等优点.目前我国广泛使用的草甘膦制剂主要以异丙胺盐和铵盐为主,为探明草甘膦钾盐水剂的除草效果,用30%草甘膦钾盐水剂进行了非耕地杂草防除试验,试验设计采用随机区组排列,施药方法为茎叶处理.试验结果表明,30%草甘膦钾盐水剂对非耕地杂草有很好的防治效果,用药后15 d,对杂草的总防效在95%以上,推荐使用剂量为1 000~2 000 g/hm2.

关 键 词:30%草甘膦钾盐水剂  非耕地  杂草防除  田间试验

Abstract:
Glyphosate is a no selective herbicide that has many advantages such as high effect,low dosage,low toxicity,wide weed control spectrum,free application stage and so on.The widely used glyphosate formulations are mainly isopropylamine salt and ammonium salt in China.The study aimed to explore the control effect of 30% glyphosate potassium salt AS against weeds.For this reason,glyphosate potassium salt 30% AS was applied to control weeds in non-crop land.Spraying method was leaf spraying and experimental design was the randomized block arrangement.The results showed that glyphosate potassium salt 30% AS had a good weed control effects in non-crop land.After spraying the herbicide 15 d,the total of the weed control effect was over 95%.The use of active ingredients dose which recommended was 1 000~2 000 g/hm2.
Keywords:glyphosate potassium salt 30% AS  non-crop land  weed control  field trials
