摘　　要：试验表明,秸秆全量还田条件下,苗后除草剂烟嘧磺隆和苞卫以及与阔草清、耕杰、溴苯腈混用可有效防除玉米田杂草,药后45 d杂草株防治效果在90.73%~95.30%,并具有一定增产作用,增产幅度23.92%~28.60%。Tests showed that under all maize straw returning conditions, the after seedlings herbicide nicosulfu-ron or BAS 670 H, mixing with Flumetsulam or Mesotrione and Atrazine or Bromoxynil could control corn fieldweeds effectively. Its control effects after 45 days were 90.73%~95.30%. It also has yield increasing function, andmaize yield increased by 23.92%~28.60%.
