了解稻田除草剂对田埂显花植物的影响,为稻田除草剂的应用提供参考。试验研究了稻田4种常用除草剂五氟磺草胺、氰氟草酯、苄嘧磺隆、二氯喹啉酸对田埂显花植物芝麻、大豆的影响。结果表明,4种除草剂不论是土壤处理还是茎叶处理,均以二氯喹啉酸对芝麻的影响最大,对芝麻的生长抑制率均为0.834~1.000;土壤处理中,二氯喹啉酸对大豆的影响最大,生长抑制率为0.991~0.994,茎叶处理中,氰氟草酯对大豆的影响最大,生长抑制率为0.477~ To understand the effect of rice field herbicide on the flowering plants, provide a reference for the application of herbicide in paddy fields. The effects of four herbicides, penoxsulam, cyanafos, bensulfuron-methyl and quinclorac, on the sedge and soybean in the field were studied experimentally. The results showed that the four herbicides had the most significant effect on the sesame seeds with both quinclorac and soil treatment. The inhibition rates of the four herbicides to sesame seeds were 0.834-1.000. In the soil treatment, , The growth inhibition rate was 0.991 ~ 0.994. In the treatment of stem and leaf, Cyhalofop-ethyl had the strongest influence on soybean with the growth inhibition rate of 0.477 ~
