The effect of chemical control of Mikania micrantha on soil enzyme activity
摘要
Abstract
To understand the impact of chemical control over Mikania micrantha on soil ecological environment,we assessed the control effects of 25％2,4-D picloram,24％2,4-D clopyralid and 70％sulfometuron-methyl on Mika-nia micrantha and evaluated their effects on soil enzyme activity.The results showed that the killing rate of 25％2,4-D picloram and 24％2,4-D clopyralid on Mikania micrantha was 100％,and the control effects were signifi-cantly higher than that of 70％sulfometuron-methyl.Additionally,25％2,4-D picloram significantly promoted soil catalase activity,while 24％2,4-D clopyralid did not affect soil catalase activity.On the 14th,21st,and 49th day after spraying,the activity of soil catalase under 25％2,4-D picloram was significantly higher than that under 70％sulfometuron-methyl.The effects of 25％2,4-D picloram and 24％2,4-D clopyralid on soil phosphatase activity exhibited a"promotion-inhibition"pattern,while 70％sulfometuron-methyl did not affect soil phosphatase activity.On the 14th day after spraying,the activity of soil phosphatase under 25％2,4-D picloram was significantly higher than that under 24％2,4-D clopyralid and 70％sulfometuron-methyl.The effect of 24％2,4-D clopyralid on soil urease activity exhibited a"promotion-inhibition"pattern,while 25％2,4-D picloram and 70％sulfometuron-meth-yl did not affect soil urease activity.On the 14th day after spraying,the activity of soil urease under 25％2,4-D picloram was significantly lower than that under 24％2,4-D clopyralid.Overall,soil enzyme activity can be used as an indicator to characterize soil pollution after chemical control of Mikania micrantha.关键词
