摘　　要：为研究药剂防效和对玉米的安全性,采取随机区组设计,比较33%氯氟吡氧乙酸·烟嘧磺隆·莠去津和4%烟嘧磺隆同两种助剂组合对杂草防除效果和产量的影响。结果表明:33%氯氟吡氧乙酸·烟嘧磺隆·莠去津的防治效果要比4%烟嘧磺隆的防草效果好,河北农业大学提供的助剂效果要优于99%甲酯化大豆油增效剂。In order to study the control effect and the safety of herbicides on maize,a randomized block design was used to compare the effects of 33%CFPA·nicosulfuron methyl·atrazine and 4%nicosulfuron methyl combined with two adjuvants on weed control and yield.The results showed that the control effect of 33%chlorofluoropyranoic acid·nicosulfuron methyl·atrazine was better than that of 4%nicosulfuron methyl,and the adjuvant effect provided by Hebei Agricultural University was better than that of 99%methylated soybean oil synergist.
