采用室内整株生测法测定了不同时期施用47%氯吡·丙·异WP对麦田主要杂草种群的防除效果。结果表明,47%氯吡·丙·异WP播后苗前1 350~4 500 g/hm2或杂草2~3叶期1 800~3 600 g/hm2处理对江苏省小麦田主要恶性杂草菵草、日本看麦娘、看麦娘、硬草、早熟禾、繁缕、大巢菜、野老鹳、荠菜地上部分鲜质量防效均大于90%,47%氯吡·丙·异WP播后苗前施用对杂草防效优于杂草2~3叶期施用;播后苗前或杂草2~3叶期施用47%氯吡·丙·异WP对猪殃殃地上部分鲜质量具有抑制作用,但防效稍差。
The indoor whole plant method was used to test the control effect of 47% clopidogrel, cinnamonin and WP in different periods on the main weed population in wheat field. The results showed that the treatment of 47% clopidogrophenolecalciferol WP after sowing 1 350 ~ 4 500 g / hm2 or 2 800 ~ 3 600 g / hm2 of weeds 2 ~ 3 leaf stage of wheat in Jiangsu Province, the main weed weeds Chinense japonica, Anemarrhena asparagus, Maize grass, hard grass, bluegrass, plumbago, big vetch, wild stork, shepherd’s purse Pre-emergence application of weed control weeds better than 2 to 3 leaf stage application; sowing pre-emergence or weeds 2 to 3 leaf stage application of 47% of clopidogrel, Has inhibitory effect, but slightly less effective.
