以玉洋洋、玉临军、苞卫、随薏打和金都尔5种化学除草剂为试验药剂,以丹玉8479为试验玉米品种,研究南繁玉米试验田的杂草防治效果。结果表明：不同除草剂间对杂草的防效存在差异性,玉洋洋和随薏打防效较好,最高值超过90%；苞卫和金都尔的防效周期较长,达到30-35天。5种除草剂对玉米都相对安全,对收获产量影响也较小。综合防治效果和防控周期两方面考虑,在南繁玉米试验田根据不同需要建议使用玉洋洋和苞卫2种除草剂。根据海南冬季农田生产的特殊性,施用除草剂时应严格控制剂量并防止漂移,避免对周围瓜菜和后茬作物产生影响。
英文摘要:
Common maize hybrid Danyu8479 was used as the material to test the control effect of five herbicides on weeds on south off-season breeding in maize field. The results showed that control effect had significant differences on different herbicides, the highest control effect of Yuyangyang and Suiyida were better of more than 90%, Baowei and Jinduer had a long cycle control effect to 30-35 days. The effect to maize were relatively safety and little influence on yield of five herbicides. It was recommended to use 2 kinds of herbicides Yuyangyang and Baowei on south off-season breeding in maize field considering both control effects and control cycle. Due to the particularity farmland production of Hainan winter, it should strictly control the dose and prevent drift whenSspraying herbicide to avoid the adverse effects of surrounding crops.
