Ｃ─绿黄隆结合残留物．结果表明，在培育５ｄ后，有３４．４０％－４０．５５％的

Ｃ－结合残留物被释放出来，以可提取态存在于土壤溶液中，其数量在以后的试验过程中变化不大。微生物释放

Ｃ－结合残留物时，主要对存在于富里酸中的结合残留物产生作用。与对照相比，利用的微生物Ｂａｃｉｌｌｕｓｍｅｇａｔｅｒｉｕｍ和Ａｒｔｈｒｏｂａｃｔｅｒｓｐ．未表现出较强的释放能力。

Abstract

Microorganisms were used to release

C-chlorsulfuron bound residues from soil. It was revealed that 34.40%-40.55% of total bound residues became extractable after incubation for 5 days

and the amounts of these residues changed slightly thereafter. It was also showed that those residues which existed in fulvic acid（FA） fraction of soil organic matter would be preferentially released by microorganisms. Compared with the control

two bacteria

Bacillus me gaterium and Arthrobacter sp.

did not demonstrate a strong ability to release bound residues.
