摘　　要：应用10%草甘膦水剂、快招(41%草甘膦异丙胺盐水剂)、20%克无踪水剂等3种除草剂对青海云杉苗圃地开展了除草试验。结果表明:3种除草剂中以"快招"效果最好,浓度以10 mg·g-1为宜。在晴朗无风的中午,采取定向喷雾,对青海云杉苗圃地杂草有较好的防除效果;和人工除草相比较,使用"快招"除草可节省费用73.3%。A herbicide trial was conducted on Picea crassifolia nursery by applying 10% glyphosate solution,＂Kuaizhao＂（41% glyphosate isopropylamine）,and 20% no-trace herbicide. Result shows that ：among three herbicides,the optimal effect of＂Kuaizhao＂herbicide is 10 mg·g^-1. At noon on a clear,windless day,directional spray has optimal control effect for weeding in the nurseries of Picea crassifolia. Compared with manual weeding,using ＂Kuaizhao＂for weeding can save costs by 73. 3%.
