利用生物固定土壤重金属的机理及在农产品安全中的应用

摘要/Abstract

摘要： 生物固定技术是土壤重金属污染防治和保障农产品安全的有效手段.目前利用生物固定土壤中的重金属主要有三种途径:①利用土壤微生物固定重金属;②利用植物根分泌物固定重金属;③利用植物-微生物联合固定重金属.本文阐述了生物固定技术在解决土壤重金属危害中的重要意义及利用土壤微生物和植物根分泌物固定重金属的机理,提出了农作物选育及改良、高效微生物菌剂的选育及应用等具体措施以保障农产品安全.

Abstract: Heavy metal pollution in soil is one of the most significant causes to decrease the food security and injure people’s health. Bio-stability is an important technology to prevent agricultural production from heavy metals contamination because they are difficult to be cleared away. There are three bio-stabilizing methods including using soil microorganism, root exudation of plants and plant-microorganism system to stabilize heavy metals in soil. This paper dealt with the mechanism of heavy metal bio-stabilization in the soil and its application to agricultural product security.
