摘    要:采用室内模拟试验方法,研究了丁草胺在三种不同有机质含量土壤中的吸附特性曲线,采用批量平衡法,用三种土壤对丁草胺进行吸附,并通过改变三种土壤的投加量、温度和pH进行实验。实验结果表明,丁草胺在三种不同土壤中的吸附平衡时间大约为12h,以快速吸附为主,土壤的有机质含量是影响土壤吸附性能的重要因素,土壤有机质含量与土壤对农药的吸附呈正相关,土壤的投加量越大固相中的吸附量也越大,丁草胺在土壤中的吸附随着温度的升高而减弱,但影响并不明显;碱性条件不利于土壤对丁草胺的吸附量。

关 键 词:丁草胺  土壤有机质  吸附

Abstract:Batch experiments were done to study the adsorption characteristics of butachlor in three kinds of soil containing different organic matters as well as the factors affecting butachlor adsorption by changing quantity of soil,temperature and pH value of butachlor.Results of the experiment indicated that the balance time of adsorption of butachlor on the soils was about 12h,with main adsorption of butachlor as celerity adsorption.Quantity of organic matter in soil was the most important factor that affected th...
Keywords:butachlor  organic matter of soil  adsorption
