| 摘 要： | 在大田试验中研究了毒死蜱和丁硫克百威两种农药对香蕉园土壤酶活性的影响。结果表明,毒死蜱和丁硫克百威在施入土壤初期对4种土壤酶活性有明显影响。毒死蜱和丁硫克百威两种农药都对脲酶和淀粉酶活性有抑制作用;对磷酸酶活性表现为先抑制后激活。毒死蜱对过氧化氢酶活性有激活作用,而丁硫克百威对过氧化氢酶活性作用表现为抑制-激活-抑制的趋势。施用毒死蜱后,4种土壤酶活性都可在1~2周内恢复到对照水平;施用丁硫克百威后,土壤脲酶、磷酸酶和淀粉酶活性都在1~2周内恢复到对照水平,而过氧化氢酶活性需要4周才能恢复。毒死蜱和丁硫克百威对4种酶活性的影响在短时间内恢复,说明这两种农药对土壤酶活性不会造成严重危害。

| Abstract: | Effects of chlorpyrifos and carbosulfan on the soil enzymes activity of banana plantation were studied in this experiment.The results indicated that distinct effects of two pesticides on the soil enzymes activity were showed in the early stage.The effects went as follows: Urease activity and amylase activity were inhibited,while phosphatase activity was firstly inhibited then activated by both pesticides.For the activity of catalase,activation was exhibted by chlorpyrifos and the trend of inhibition-activat... |
