摘要: |
研究了呋喃丹、铁灭克、天王星3种农药对土壤磷酸酶活性的抑制作用。结果表明,3种农药在不同农药用量、培养时间、磷酸苯二钠用量及外加不同pН值缓冲溶液时,对磷酸酶活性均有不同程度的抑制作用。同时,在该条件下进行回归分析建模时发现不同农药用量、磷酸苯二钠用量对磷酸酶活性影响的相关系数均大于0.990 0。证明了在本地区特有的农业环境条件下,这3种农药可能会影响和破坏农业生态环境。 |

Effect of three insecticides on soil phosphatase activity |
|
Abstract: |
Inhibiting effect of three pesticieds (furadan,aldicarb,bifenthrin) on soil phosphatase activity was studied.The different dose,incubating time,phenyl phosphate dinatrium dose levels and adding buffer solution with different PH were experimented and analyzed.The results showed that all the three treatments can inhibit the activity of soil phosphatase,and the activity of soil phosphatase was significantly affected by the doses of pesticides and phenyl phosphate dinatrium (R>0.990 0).It also implied that there was a possibility that agricultural chemicals would affect the agrological environment. |
Key words: pesticide soil phosphatase activity |
