我国南方红壤酸化问题及改良修复技术研究进展

Status of Red Soil Acidification and its Amelioration Technologies in South China

近年来我国南方红壤酸化问题日益突出,严重制约了该区域的粮食安全和农业可持续发展。主要介绍了南方红壤酸化的现状和危害,总结了近年来红壤酸化加速的主要成因,从无机改良、有机改良、生物修复和生物质炭改良修复酸化土壤等4个方面分析了红壤酸化改良修复技术及基本原理,以期为红壤酸化改良修复工作提供参考。

In recent years, the problem of red soil acidification in south China has gotten worse, which seriously affected the regional food security and agricultural sustainable development. This paper mainly introduced the status of red soil acidification in south China and its harmness to crops and environment, and summarized the main reasons of red soil acidification accelerating in south China in recent years.The basic principle and amelioration technologies of red soil acidification were introduced from four aspects such as inorganic modification, organic modification, bioremediation and biomass carbon applying in this paper. We hope to provide reference for the work of amelioration red soil acidification.
