| 摘 要： | 通过对呋喃丹、铁灭克、天王星3种农药对土壤脲酶活性的抑制性进行试验 ,分析了不同农药用量、培养时间、尿素用量及外加不同 pH值缓冲溶液的情况下对脲酶活性的影响。结果表明 ,3种农药在不同情况下对脲酶活性均有不同程度的抑制作用 ,也证明了在本地区特有的农业环境条件下 ,农用化学物质可能会影响和破坏农业生态环境

| Abstract: | Inhibiting effects of three pesticides (carbofuran, aldicarb, bifenthrin) on soil urease activity were studied with different doses, incubating times, urea dose levels and adding buffer solution with different pH values. The results showed that all treatments exhibited inhibitions on the urease activity in soil. It was clearly suggested that all tested agro-chemicals could affect agro-environment. |
