摘要：
This paper describes the movement of fluometuron in two soils by: (a) the use of soil columns, and them to study the distribution with depth of Dactylis bioassay in the split soil leaching columns; (b) the Radio-autograms of soil by tic plates. The results suggest that fluometuron is mobile in soils containing low organic matter. Also the Freundlich adsorption isotherms were developed, and the adsorption coefficient (K) values were higher when soils high in organic matter. The relationship of to the Freundlich constant K to the Rf values of radioautograms is discussed. © 1991, Taylor & Francis Group, LLC. All rights reserved.
