| 摘 要： | 以张杂谷8号为试材,研究了12.5%拿扑净、44%谷友可湿性粉剂、72%2甲4氯可湿性粉剂和2,4-D丁酯对谷田杂草的防除效果,以筛选适宜谷子的除草剂种类。结果表明:谷苗4叶期喷施拿扑净,可有效防除禾本科杂草,平均防效为88.63%;阔叶杂草4～5叶期喷施2甲4氯,可有效防除阔叶杂草,平均防效达96.75%。2种药剂结合使用,能达到理想的谷田杂草防除效果。

| Abstract: | Using Zhangzagu No.8 as the tested material,the effects of 12.5% sethoxydim,44% guyou,72% methoxone,and 2,4-D on the weed control in millet field were studied.The results showed that 12.5% sethoxydim could control grass weeds effectively during 4-leaf stage with the efficiency of 88.63%.72% methoxone could control broadleaf weeds effectively during 4 or 5-leaf stage with the efficiency of 96.75%.The efficiency was enhanced when the two kinds of herbicides were applied. |
