在实验室内，采用改进的玉米根长生测方法，定期测定一定温、湿度条件下绿黄隆在３种土壤中的残留动态。对降解时间和残留剂量进行回归分析，符合一级反应动力学指数方程Ｃ＝Ｃ０ｅ－ｋｔ，相关系数达极显著水平，半衰期ｔ１／２＝ｌｎ２／ｋ。实验结果表明，在２５℃、２５％温、湿度条件下，绿黄隆在太湖水稻土中降解最快，半衰期为１．６周；其次是砂姜黑土，半衰期为２．５周；高砂土中降解最慢，半衰期为１３．３周。分析认为，土壤ｐＨ值和微生物量是影响绿黄隆降解的主要因素。高温灭菌土壤测得绿黄隆在砂姜黑土的灭菌土和未灭菌土中，半衰期分别为２６．５周和２．１周；太湖水稻土的灭菌和未灭菌土中，半衰期分别为５．０周和０．９周。从而进一步证实，绿黄隆在太湖水稻土中以非酶水解和微生物活动共同降解，在碱性砂姜黑土中主要以微生物降解。探讨了绿黄隆在３种土壤中的残留动态对农业生产的重要性，建议长江流域碱性沙质土壤农区慎用或禁用绿黄隆。
In the laboratory, the improved method of root length measurement of maize was used to periodically measure the residual dynamics of chlorsulfuron in three kinds of soil under certain temperature and humidity conditions. Regression analysis of the degradation time and residual dose, in line with the first-order reaction kinetics index equation C = C0e-kt, the correlation coefficient reached an extremely significant level, half-life t1 / 2 = ln2 / k. The experimental results showed that under the conditions of 25 ℃, 25% temperature and humidity, the highest degradation rate of the green Huanglong was in the paddy soil of Taihu Lake with a half-life of 1.6 weeks, followed by saprolimitic black soil with a half-life of 2.5 weeks. The slowest degradation, half-life of 13.3 weeks. The analysis shows that soil pH value and microbial biomass are the main factors that affect the degradation of chuanluonong. The results showed that the half-lives of chlor-flavonoids in the soil of autoclaved soil were 26.5 weeks and 2.1 weeks respectively in the sterile soil and non-sterile soil of Shajiang black soil, The half-lives were 5.0 and 0.9 weeks respectively. It was further confirmed that the chlorosulfon in Taihu Lake paddy soil by non-enzymatic hydrolysis and microbial degradation of common activity, in alkaline Shajiang black soil degradation of microorganisms. This paper discussed the importance of the residual dynamics of chlor-flavonoids in three kinds of soils to agricultural production. It is suggested that chlor-flavonoids should be used with caution or not in the alkaline areas of sandy soils in the Yangtze River.
