摘要:
为了治理退化草原的杂草，促进草地稳产、高产和可持续利用，用两种除草剂（72%的2,4-D丁酯和48%灭草松水剂）3个不同剂量浓度对羊草草原的杂草进行防除试验。结果表明：2,4-D丁酯和灭草松除草剂对羊草草原可饲牧草安全无害。2,4-D丁酯除草剂施用浓度为1 458 mL?hm-2时，杂草株防效和鲜重防效均较高，灭草松施用浓度为5 400 mL?hm-2时对刺菜株防效较好，在实际应用中可结合杂草分布情况混合复配两种除草剂提高杂草防除效果。
Abstract:
In order to control the weeds of degraded grassland and promote grassland stable high yield and sustainable utilization,three dose levels of two herbicides (72% 2,4-D butylate EC and 48% bentazone aqueous solution) were used for the weed control test in Leymus chinensis grassland.The results showed that 2,4-D butylate and bentazone were safe to forage grass.When the concentration of 2,4-D butylate was  1 458 mL?hm-2,the weed control efficacy and strains fresh weight was excellent.Cirsium setosum could be controlled better when the concentration of bentazone was 5 400 mL?hm-2.In practice,combined with the distribution situation of weed,the two herbicides could be mixed to improve the weeds control effect.
