摘要: 【目的】为筛选出对胡麻田间阔叶杂草具有高效、安全防除效果的除草剂,用5种除草剂组成的6个混用组合,对胡麻进行播后苗前喷雾处理。结果表明:42%甲·乙·莠SC 1500 mL/hm2+80%丙炔噁草酮WP 180 g/hm2混用组合在试验剂量下对胡麻安全,出苗率达到53.01%,对胡麻田阔叶杂草具有优良防效。施药后45天株防效、鲜重防效分别达到97.96%、98.4%。42%甲·乙·莠SC 1500 mL/hm2+80%丙炔噁草酮WP 180 g/hm2混用组合,用水量900 kg/hm2,在胡麻播种后当天或第2天在土壤表面进行均匀喷雾处理,对胡麻田具有良好的防除效果,可在生产上大面积推广使用。

Abstract: To screen out herbicides with high efficient and safe control effect on broadleaf weeds in flax field, spraying treatments after sowing before seedling emergence were completed by 6 mixed combinations of 5 herbicides. The results showed that: 42% atrazine SC 1500 mL/hm2 + 80% oxadiargyl WP 180 g/hm2 combination was safe for flax in recommended dose and the seedling emergence rate of flax was 53.01%, showing excellent control effect on broadleaf weeds in flax field. After 45 days, the control effect of plant and fresh weight was 97.96% and 98.4%, respectively. Thus, 42% atrazine SC 1500 mL/hm2 + 80% oxadiargyl WP 180 g/hm2 with water consumption of 900 kg/hm2 for soil surface spray treatment on the first day or the second day after sowing has good control effect and can be widely used in production.
