| 摘 要： | 用24.0%乙氧氟草醚乳油,10.8%高效氟吡甲禾灵乳油及这2种药剂的混合共3种处理对红花檵木容器苗进行杂草除治试验,结果表明:喷施24%乙氧氟草醚乳油20 mL/667 m2后,第30天的株防效为90.3%、鲜质量防效为87.8%;第40天的株防效为91.7%、鲜质量防效为91.6%,均明显好于另外2种药剂处理的除草效果,且对苗木较为安全,基本上能达到除治杂草的目的,可进一步推广应用。

| Abstract: | A weed control experiment was conducted for Loropetalum chinense var.rubrum container seedlings with 24% oxyfluorfen EC,10.8% Haloxyfop-P-methyl EC,and the combination of 24% oxyfluorfen EC and 10.8% Haloxyfop-P-methyl EC.The results showed that the control effect of 20 mL/667 m2 of 24% oxyfluorfen EC 30 days after application was 90.3% out of the plants,and 87.8% by the fresh weight.While the control effect of 20 mL/667 m2 of 24% oxyfluorfen EC 40 days after application was 91.7% out of the plants,and 91.6% by the fresh weight.The weed control effect of 20 mL/667 m2 of 24% oxyfluorfen EC was better than that of the other two types of herbicide.It was also safer to the container seedlings of L.chinense var.rubrum,so it should be further extended to larger area. |
