摘要
为了了解三唑磷在甘蓝上使用的安全性,对三唑磷在甘蓝上施用后的残留消解动态,进行了试验研究。结果表明,以667mg/L施药后,三唑磷在土壤中的动态消解方程为C=0.0673e-0.1122t(r2=0.9831),半衰期为6.2d;三唑磷在甘蓝植株中的动态消解方程为C=8.7411e-0.2182t(r2=0.9453),半衰期为3.3d。
The residual dynamic experiment of triazophos in cabbage was studied in Hunanagriculture university test ground for understand the security of triazophos in cabbage.The resultsshowed that after treatment of triazophos 667mg/L,the degradation dynamic equation of triazophosin soil was C=0.067 3e-0.1122t(r2=0.983 1),the half- life was 6.2 days;the degradation dynamicequation of triazophos in cabbage was C=8.741 1e-0.2182t(r2=0.945 3),the half- life was 3.3 days.
