[目的]为了明确ZJ1835和二甲戊乐灵混用的合理性,采用温室盆栽试验,对新除草剂ZJ1835和二甲戊乐灵混用的配方进行筛选。[结果]研究结果表明:混用后对4种供试杂草的除草活性比单剂有所提高,且两者混用对供试杂草的联合作用类型为相加作用。[结论]综合考虑除草活性和经济成本,推荐ZJ1835和二甲戊乐灵的最佳配比范围为(120～240 g a.i./hm2+480 g a.i./hm2),即有效成分比例为(1～2)∶4。 [Objective] The purpose of this study was to clarify the rationality of mixing ZJ1835 with pendimethalin. The pot experiment was conducted to screen the new herbicide ZJ1835 and pendimethalin. [Result] The results showed that the herbicidal activities of four tested weeds were higher than that of the single herbicide after the mixture, and the combined effects of the two on weeds were additive. [Conclusion] Considering the herbicidal activity and economic cost, the best ratio of ZJ1835 to pendimethalin was recommended (120 ~ 240 g ai / hm2 + 480 g ai / hm2) 2): 4.
