间套作体系在污染土壤修复中的应用研究进展

我国土壤环境污染态势严峻,污染土壤的修复备受关注。植物修复技术是当今的研究热点之一,但是利用植物修复技术清洁污染土壤需时较长,且需中断农业生产。间套作体系应用于污染土壤的修复,是一条有效的新途径。为此综述了间套种在重金属和有机污染物污染土壤修复中的应用,介绍了间套作体系在减少植物对重金属的吸收、提高植物对重金属的提取以及促进有机污染物的降解等方面的作用,同时提出在土壤修复中,应根据不同的目的选择更多的适当的植物组成间套作体系,并加强间套作体系中植物间交互作用机理研究。

Innovative Technologies for Soil Remediation: Intercropping or Co-cropping

Soil pollution has become a major environmental concern in many parts of the world,and soil remediation technologies in the development.Phytoremediation has been proposed as a low-cost,environmentally friendly remediation technology,but it is generally time-consuming and requires the cessation of agriculture,phytoextraction with a single hyperacumulator may not be economically feasible for large areas of moderately-contaminated agricultural soils in China.A new approach,intercropping/co-cropping system was ...
