| 摘 要： | 选用50%莠去津WP 4个不同施用浓度,对玉米地一年生杂草和多年生杂草进行药效试验,探索不同浓度的防除效果。结果表明:4种不同浓度对玉米地杂草的防除效果以250 g/667m2防效最佳,其次是200 g/667m2。化学除草取代人工除草,可减轻农民的劳动强度,提高劳动生产率,在农业生产中具有推广价值。

| Abstract: | 4 different concentrations of 50% atrazine WP were tested to investigate the weed control effect to annual and perennial weeds.The results indicate that the best weed control effect is applying 250g/667m~(2) of 50% atrazine WP in maize fields and the method can reduce farmer labor intensity and raise the labor production rate,which can be popularized in maize production. |
