Abstract

Abstract: In order to judge of azoxystrobin on soil ecological environment safety, guide the scientific understanding and reasonable use of it, through indoor simulation method to study the azoxystrobin on soil urease activity effect. The results showed that: the urease activity of high organic content soil was high; a high protective effect on soil enzyme which the soil clay structure was high. Low concentrations of azoxystrobin to soil urease showed active effect, a high concentration of azoxystrobin on soil urease showed inhibition, but not obviously and could be eliminated; along with the culture time growing, azoxystrobin on activity of soil urease inhibition could be restored. Comprehensive evaluation, azoxystrobin was with no obvious toxic effects to soil environment, and with high safety.
