摘要
对高寒地区多年生禾草混播草地一龄的杂草进行了化学药剂的防除试验。结果表明:2,4 D丁酯、杜邦巨星和甲黄隆的最佳剂量分别为1188g/hm2,4.27g/hm2和3.32g/hm2。在最佳剂量下杂草防除效果均超过90%。
Weed control by using weedicideswas carriedout in the preliminary established (first year) perennial grassland in alpine region. The results showed that the optimum doseof 2,4-D butylate, tribenuron and methsulfuron-methyl for controllingthe weeds was 1 188 g/hm^(2),4.27 g/hm^(2), 3.32 g/hm^(2), respectively.
