研究了１４Ｃ－抗蚜威在８种土壤中的吸附解吸附行为。结果表明，不同土壤对该杀虫剂的吸附能力差异很大，吸附率低的仅为１３．１６％，高的达８７．７５％。同种土壤对抗蚜威的吸附量随农药的浓度增高而增大，但在一定浓度范围内，吸附量几乎不受抗蚜威浓度的影响。根据研究结果建立了土壤基本理化性质对吸附率综合影响的多元回归方程（达显著水平），并找出了影响吸附率关键因子：ｐＨ和粘粒含量。这两者分别与吸附率呈极显著负相关和极显著正相关。１４Ｃ－抗蚜咸在土壤中的吸附平衡不仅可用Ｆｒｅｕｎｄｌｉｃｈ等温方程描述，也可用Ｌａｎｇｍｕｉｒ等温方程描述。土壤吸附的抗蚜威会发生解吸附作用，解吸率也受土壤性质影响，同样也可用多元回归方程描述
The adsorption-desorption behavior of 14C-pirimicarb in 8 soils was studied. The results showed that the adsorption capacity of different insecticides in different soils varied greatly, with a low adsorption rate of only 13.16% and a high of 87.75%. The adsorption amount of pirimicarb on the same soil increased with the increase of pesticide concentration, but at a certain concentration range, the adsorption amount was hardly affected by the concentration of pirimicarb. According to the research results, a multiple regression equation (up to a significant level) of the comprehensive effect of soil basic physical and chemical properties on the adsorption rate was established, and the key factors influencing the adsorption rate were found: pH and clay content. The two were significantly and negatively correlated with the adsorption rate and very significant positive correlation. The adsorption equilibrium of 14C-resistant aphids in soil can not only be described by the Freundlich isotherm equation, but also by the Langmuir isothermal equation. Anti-pirimicarb adsorption of soil desorption occurs, the desorption rate is also affected by the nature of the soil can also be described by multiple regression equation
