本文研究了其在3种土壤中有氧环境下的降解情况。呋喃虫酰肼在3种土壤中的降解速率大小依次为河南黄土>吉林黑土>江西红土,其降解半衰期分别为315、365、213d,降解遵循一级动力学方程。根据国内农药在土壤中的残留划分标准,呋喃虫酰肼属于较难降解类农药。比较呋喃虫酰肼在非灭菌与灭菌的吉林黑土、江西红土和河南黄土中的降解情况表明,药剂在非灭菌土中降解明显加快,分析可能是土壤中微生物对呋喃虫酰肼的降解具有显著的影响。
In this paper, the degradation of three kinds of soil under aerobic conditions was studied. The degradation rates of furazolidone in three soil types were as follows: Henan loess> Jilin black soil> Jiangxi red soil. The degradation half-lives of furazide hydrazide were 315, 365 and 213 days, respectively. The degradation followed the first-order kinetic equation. According to the standard of pesticide residues in soil, furazolidone hydrazide belongs to pesticide which is more difficult to degrade. The degradation of furazolidone in non-sterilized and sterilized Jilin black soil, Jiangxi laterite and Henan loess showed that the degradation of furan insecticide significantly accelerated in non-sterilized soil, Degradation has a significant effect.
