植物修复重金属污染土壤的研究现状及其水肥调控技术展望
Research Status of Phytoremediation of Heavy Metals Contaminated Soil and Prospects of Water and Fertilizer Regulating Technology
摘要
Abstract
In order to build ecological civilization construction and sustainable development of the economy and society, and no delay for controlling of heavy metals contaminated soil. Based on a system analysis by the current situation of heavy metals contaminated soil and the major problems in phytoremediation of heavy metals contaminated soil, this paper presents that water and fertilizer regulating technology is the important measure to solve the problems of small biomass and slow growth in the remediation process of heavy metals contaminated soil at this stage. Comprehensively considering the real-time dynamic process of major heavy metals pollution in soil and the characteristics of plant growth, as well as the effects of soil micro-environment (water, fertilizer, gas, heat and microbial) of root zone, analyzing the mutual relationships between them. With water and fertilizer regulating technology as the means, to improve plant biomass as the target, which has been made the best mode of water and fertilizer regulating technology for phytoremediation of heavy metals contaminated soil. The paper also looks ahead five aspects on phytoremediation of heavy metals contaminated soil based on water and fertilizer regulating technology and analyzes the difficulties, innovative points and further research direction of water and fertilizer regulating technology in the process of phytoremediation ofheavy metals contaminated soil.关键词
