[目的]探索植物生长调节剂与除草剂混用后对减轻作物药害和提高除草剂药效的影响。[方法]采用室内盆栽的方法,研究芸苔素内酯和胺鲜脂分别与不同除草剂混用后对水稻药害的减轻作用或是生长促进的作用,同时研究这2种植物生长调节剂对除草剂药效的影响作用。[结果]二氯喹啉酸与芸苔素内酯混用能够提高对稗草的防效;唑草酮与胺鲜脂混用,不仅可以减轻对水稻的药害,而且对水稻的生长有一定的促进作用;二氯喹啉酸与胺鲜脂混用,稗草的防效降低,对水稻的药害加重;嘧啶肟草醚与芸苔素内酯混用,对水稻的药害加重。[结论]植物生长调节剂与除草剂混用是减轻作物药害和提高除草效果的一个有效途径。
[Objective] The research aimed to explore the effects of combination of plant growth regulator and herbicide on alleviating crop phytotoxicity and improving herbicide efficacy. [Method] The indoor potted method was used to study the mitigation effect or growth promoting effect of brassinolide and amine fresh fat mixed with different herbicides on rice phytotoxicity respectively. At the same time, the effects of these two plant growth regulators on Effect of Herbicidal Efficacy. [Result] The combination of quinclorac and brassinolide increased the control effect on barnyardgrass. The combination of oxacillin and amine fresh fat could not only reduce the phytotoxicity to rice, but also promote the growth of rice The effect of quinclorac combined with the fresh fat of amine and the control effect of barnyardgrass decreased and the phytotoxicity of rice increased. The combination of saflufenacil and brassinolide increased the phytotoxicity of rice. [Conclusion] The combination of plant growth regulator and herbicide is an effective way to reduce crop phytotoxicity and enhance herbicidal effect.
