摘　　要：为探讨谷子田化学除草方法,促进节本增收,以嫩选15为试验材料,开展苗前封闭除草剂筛选试验,考察不同除草剂对窄叶杂草的防效和对作物的安全性。结果表明:每100kg种子使用益佩威600mL包衣,并用二甲戊灵150mL·(666.7m^(2))^(-1)+莠去津150mL·(666.7m^(2))^(-1)封闭除草具有较好的防除效果和经济效益,可初步用于谷子大面积种植条件下的杂草防除。In order to explore the chemical weeding methods in millet fields and promote cost saving and income increase,the screening test of closed herbicides before seedling was carried out with Nenxuan 15 as test materials to investigate the control effects of different herbicides on narrow leaf weeds and their safety to crops.The results showed that each 100kg seeds was coated with 600mL EPEC seed coating agent,and closed weeding was carried out with 150mL·(666.7m~2)of dimethylpentalin+150mL·(666.7m~2)of atrazine.It had good control effect and economic benefits,and can be initially used for weed control under large-scale planting of millet.
