应用土壤薄层层析(TLC)法测定了14C-绿黄隆在10种土壤中的移动率,其Rf值为0.65~1.0,表明绿黄隆在供试土壤中分别属可移动性和极易移动性。用大面积土柱淋溶法测得3种土壤柱在模拟降雨下的淋溶动态及其参数,经计算,在黄潮土、黄棕壤和红壤中,使14C-绿黄隆垂直移动透过10cm土层所需连续降水量分别为75,80和94mm。绿黄隆在土壤中的迁移性与土壤PH值密切相关,随pH值增高其移动性和淋溶性增大。绿黄隆随水迁移性较强,它有可能对农业生态环境产生不良影响。
The thin film chromatography (TLC) method was used to determine the mobility of 14C-chlorosulfon in 10 soils, and the Rf value was 0.65-1.0. Mobility and extreme mobility. The leaching dynamics and parameters of three soil columns under simulated rainfall were measured by a large area soil column leaching method. Through calculation, the 14C-chlorosulfone was vertically moved through 10 cm in Huang Chao soil, yellow brown soil and red soil The amount of continuous precipitation required for the soil layer is 75, 80 and 94 mm respectively. The mobility of chlor-flavonoids in soil is closely related to the pH value of soil, and the mobility and leaching of chlor-flavonoids increase with the increase of pH value. Green Huanglong strong migration with the water, it may have an adverse impact on agricultural and ecological environment.
