农田重金属污染植物–腐殖质修复研究进展
Research Progress in Remediation of Heavy Metals Contaminated Farmland by Plants-Humus

农田重金属污染已成为困扰农田土壤健康的关键问题，农田土壤重金属污染治理已成为科研、生产和人民生活密切相关的热点问题。本文通过系统梳理近年来国内常用的农田重金属污染修复技术及其实践经验，并重点阐述了植物–腐殖质修复技术的实施原理、应用效果及未来展望，为我国农田重金属污染控制工作的发展提供借鉴。发展原位肥力维持性绿色综合修复技术、降低农田重金属的生物有效性、保障农作物正常生长及收获，是保障我国粮食安全的必备要素。
Heavy metal pollution in farmland has become a key problem troubling the health of farmland soil, and the management of heavy metal pollution in farmland soil has become a hot issue closely related to scientific research, production, and people’s life. In this paper, the common farmland heavy metal pollution remediation technologies and their practical experience in recent years are systematically sorted out, while the implementation principle, application effect, and future prospect of plants-humus remediation technology are highlighted, so as to provide references for the development of farmland heavy metal pollution control work in China. The development of in situ fertility maintenance green integrated remediation technology, reducing the biological effectiveness of heavy metals in farmland, and guaranteeing normal crop growth and harvest are essential elements to ensure food security in China.
