[目的]筛选适于东北裸燕麦田使用的除草剂。[方法]以仲丁灵、丙炔氟草胺、苯嘧磺草胺为土壤处理剂,2,4-滴丁酯、硝磺草酮、苯嘧磺草胺为茎叶处理剂,评价不同剂量下对裸燕麦田杂草的防效和对裸燕麦的安全性。[结果]供试的几种除草剂均对裸燕麦产生了一定药害,但生长后期药害症状基本消失。除仲丁灵外,其他处理对杂草的防效均超过80%。50%丙炔氟草胺WP 40 g a.i./hm2、70%苯嘧磺草胺WG 33.3 g a.i./hm2土壤处理和10%硝磺草酮SC 100 g a.i./hm2茎叶处理产量和人工除草对照间没有显著性差异。[结论]上述3种处理具有在裸燕麦田的应用价值。 [Objective] The research aimed to screen the herbicide suitable for naked oat field in Northeast China. [Method] With different concentrations of camphorsyl, propyrofos and saflufenacil as soil treatment agents, 2,4-D-butyl ester, mesotrione and saflufenacil as stem and leaf treatment agents, Control Effect of Weeds in Naked Oats Field and Safety on Naked Oats at Dose. [Result] The tested herbicides all had a certain phytotoxicity on naked oats, but the symptom of phytotoxicity disappeared in the late growth stage. In addition to Zhong Ding Ling, the other treatment weed control effect is over 80%. 50% propyrofluride WP 40 g ai / hm2, 70% saflufenacil WG 33.3 g ai / hm2 soil treatment and 10% mesotrione SC 100 g ai / hm2 stem leaf yield and artificial weeding control There is no significant difference between. [Conclusion] The above three treatments had the application value in naked oat field.
