摘要
通过对拟除虫菊酯类、有机磷类、有机氯类、氨基甲酸酯类、酰胺类九种农药对土壤脲酶活性的影响进行了试验 ,分析了不同农药用量、不同尿素用量情况下对脲酶活性的作用。试验结果表明 ,九种农药在不同情况下对脲酶活性均有不同程度的影响作用 ,也证明了在本地区特有的农业环境条件下 。
The experiment has been conducted to determine the effect of nine kinds of pesticides on soil urease activity under different dose and urea dose levels . The results show that these treatments all can influence,to different extent,the activity of soil urease.It also proves that the ecological environment could be affected or even destroyed by agricultural chemicals in this area.
