摘　　要：对青海省春小麦田常用6种除草剂进行药害症状诊断研究。2,4-D丁酯、氯氟吡氧乙酸两种除草剂高量的倍量处理区小麦药害等级达到4级,其余4种除草剂各处理小麦药害在3级以下。结果表明,在青海省土壤气候条件下,6种除草剂的药害发生情况不严重,对小麦产量影响较小。The aim of this research was to diagnose herbicide phytotoxicity and compare the effects of 6 kinds of herbicides on field of spring wheat in Qinghai. At the areas with doubling dose of maximum dose level of 2, 4-D and Fluroxypyr, the herbicide phytotoxicity of wheat reached to the degree of 4, while the herbicide phytotoxicity of wheat reached under the degree of 3 at the areas with the other 4 kinds of herbicide. The results showed that the herbicide phytotoxicity of these 6 kinds of herbicide was not serious, and 6 kinds of herbicide had little effect on the yield of spring wheat in Qinghai.
