摘要
我国盐渍化土壤面积大,已严重制约了农业的发展和土壤的循环利用,修复盐渍化土壤有利于增加我国耕地面积、提高粮食产量。盐渍化土壤通常采用物理、化学和生物3种方法进行修复。相比于化学和物理修复法,生物修复法利用生物的生命代谢活动降低土壤的盐分,更经济、环保和高效,因此已在盐渍化土壤修复中得到广泛应用。文章总结了土地盐渍化危害及我国土地盐渍化现状,论述了植物、微生物和微生物-植物联合修复盐渍化土壤的机制和研究现状,并展望了生物法修复盐渍化土壤的应用前景。
Soil salinization is one of the main factors seriously restricting agricultural development and soil recycling.As China has a vast area of saline land,the restoration of saline soil is thus of great significance to increase the arable land area and crop yield.Saline soil is usually remediated by physical,chemical and biological methods.Biological remediation reduces soil salinity by utilizing biological metabolic activities.Compared with chemical and physical methods,biological remediation is more economical,environmentally friendly and efficient,so it is widely used in saline soil remediation.This study summarizes the harm of soil salinization and the current situation of soil salinization in China,discuesses the mechanism and research progresses of plant,microorganism and microorganism-plant combined remediation of saline soil,and prospects the application prospect of biological remediation of saline soil.
