苄嘧磺隆对生物群落的影响及其归趋因素分析

Bensulfuron's Impacts on Ecological Environment and Factors Affecting Its Adsorption and Degradation

综述了苄嘧磺隆(BSM)对生物群落的作用,并分析了影响其吸附、降解的因素。重点讨论了苄嘧磺隆对微生物群落的影响、对水体生物与后茬作物的影响,其中对作物的影响主要包括BSM与重金属的复合作用、对叶绿素合成的影响、对根生长的影响;影响苄嘧磺隆吸附、降解的因素包括土壤性质对其吸附解吸的影响、细菌对BSM的降解作用。指出乙酰乳酸合成酶(ALS)的基因突变对BSM的除草效果影响及微生物对BSM的降解率研究亟需加强。

This paper reviews the influence of bensulfuron（BSM） on biological communities,and analyzes the factors influencing the absorption and degradation of BSM.Emphasis are given on the influence of BSM on microbial community,aquatic creatures and succeeding crops as well.BSM affects crops through the co-effect of BSM and heavy metals,and in hibiting chlorophyll synthesis and root growth.The factors influencing the adsorption and degradation of BSM include soil properties and bacteria,etc.The paper points out that the influence of gene mutations of acetolactate synthase（ALS） on the weed removability of BSM and the degradation rates of BSM by microorganism should be strengthened.
