乙草胺在四种不同土壤中吸附行为研究

通过平衡振荡法测定了乙草胺在四种土壤中的吸附等温线,从影响因素、能量变化等方面研究了乙草胺在4种土壤中的吸附。结果表明:乙草胺易于被各种土壤吸附,土壤的吸附规律能够较好的符合Freundlich方程,拟合方程均有良好的线性关系。微生物的作用并没有显著改变乙草胺的吸附规律,乙草胺的吸附受到土壤有机质和矿物组成的显著影响。

Adsorption Pattern of Acetochlor in Four Different Types of Soils

In this paper, the absorption of acetochlor in four different soils were expounded as viewed from mechanism, energy change and influencing factors. The results showed that acetochlor was easily adsorpted by four different soils and the rule of absorption was fitted to the Freundlich isotherm. The rule of absorption was not observably changed by the effect of microorganism and the absorption was observably influenced by the soil organic matters and mineral composition.
