摘　　要：试验以40%立清乳油、56%二甲四氯钠、17.5%双草克星乳油、8.8%精喹禾灵的不同组合,采用不同的施药浓度,对亚麻田间杂草防控进行初步研究。在亚麻株高10 cm、田间杂草为2~4叶期时施药,施药后在不同时期观察田间亚麻药害发生情况以及恢复情况。在施药后第1、3、7、10、15天,对采用不同药剂组合的处理进行田间杂草的防治效果调查,主要调查指标为每个处理中前5位优势杂草的伤害症状、株防效以及鲜重防效。通过对施药后30、45 d的田间调查取样进行分析,得出综合除草效果以1200 g/hm2二甲四氯钠+750 mL/hm2精喹禾灵为佳,相对于空白对照(CK)总防效为92.9%。该研究为伊犁亚麻产区田间杂草的高效防治提供了科学依据。In this study,different herbicide combinations of 40%Liqing,56%MCPA·NA,17.5%Bispyribac-sodium and 8.8% Quizalofop-p-ethyl were used in diverse concentrations trial to explore the weed control in flax field.Herbicide was sprayed when the flax plant height was 10 cm and the weeds in the field were 2-4 leaf stage.The occurrence and recovery of herbicide damage on flax in different periods were investigated.The weed control effect were also evaluated on the 1st,3rd,7th,10th and 15th days after herbicide application,including the top 5 dominant weeds′damage symptom,ratio of individual weeding control effect and ratio of fresh body weeding control effect.The results showed that the optimal herbicide combination was 1200 g/hm^(2) MCPA·NA and 750 mL/hm^(2) Quizalofop-p-ethyl by analysis of field survey sampled on the 30th and 45th days after treatment.The total control effect was 92.9%,compared with CK.This research provides a scientific basis for the efficient control of weeds in the flax producing areas of Ili.
