[目的]明确稻田除草剂对4种田埂植物的安全性,为除草剂的安全使用提供理论依据。[方法]通过室内盆栽试验,测定5种稻田除草剂对4种田埂植物生长的影响。[结果]供试的5种除草剂中,不论是土壤处理还是茎叶处理,均以二氯喹啉酸影响最大,生长抑制率均为1;茎叶处理以氰氟草酯对绿豆影响最小,生长抑制率为0.192~0.296;土壤处理以氰氟草酯对绿豆影响最小,生长抑制率为0.092~0.287。[结论]土壤处理比茎叶处理更容易受到除草剂污染。
[Objective] The research aimed to clarify the safety of paddy field herbicides on four kinds of plants and provide the theoretical basis for the safe use of herbicides. [Method] The indoor pot experiment was conducted to determine the effects of 5 herbicides on the plant growth of four fields. [Result] Among the five herbicides tested, both quinclorac and quinclorac did the best, and the growth inhibition rates were all 1. The effects of cyhalofop on the mung bean were the least, The growth inhibition rate was 0.192 ~ 0.296. Cyanuric chloride had the least effect on the mung bean in soil treatment, and the growth inhibition rate was 0.092 ~ 0.287. [Conclusion] Soil treatment was more easily contaminated by herbicide than stem and leaf treatment.
