摘要
通过对不同药剂防除稻田杂草试验效果研究,结果表明,施药剂的各处理均对水稻安全,并且对杂草均有一定的防除效果,防效为92%～100%。综合分析,于插秧前5～7 d水整地后施入50%瑞飞特70 ml/667 m2,防效最好,并且节约成本,可推广应用。
Effects of herbicides on weed control in rice was studied. The results showed all treatments were safe for rice and had certain control effects on weed in rice. The control efficiency was 92% to 100%. 50% pretilachlor 70 ml/667 m^2 which was applied 5-7days before rice transplanted had the best efficiency and low cost. So it could be popularized.
