摘要
分析了土壤中镉的基本特征及污染状况;探讨了根际pH值、根际氧化还原电位、根系分泌物、根际微生物以及施用有机肥、离子拮抗、土壤磷含量和添加沸石对土壤Cd有效性的影响,以及镉污染土壤的根际环境调节。
The basic characteristics of cadmium in soil and the status of cadmium contaminated soil are analyzed.The effects of rhizosphere pH value,rhizosphere redox potential,root exudates,rhizosphere microorganisms,organic fertilizer,cadmium antagonist,phosphorus content in soil and zeolite on the effectiveness of cadmium in soil are discussed.The rhizosphere environment regulation of cadmium contaminated soil is introduced.
