土壤-植物系统中稀土元素与氮磷养分的交互作用

摘要/Abstract

摘要： 土壤植物系统中稀土元素与N、P养分交互作用属农用稀土安全性评价研究的前沿.土壤中稀土元素与N、P交互作用直接关系到稀土对农田土壤生产力的影响以及稀土对农作物的增产机理和生态环境安全性的评价.就土壤植物系统中有关稀土元素与N、P交互作用的研究作简要综述,提出今后应加强在作物根际、农田土壤表层以及植物体内稀土与N、P养分之间交互作用的研究.

Abstract: Interaction between rare earths (REs) and nitrogen and phosphorus in soil-plant system is a hot spot in the research field of safety assessment for agricultural utilized rare earths. This interaction directly affects the productivity of arable soil,and is beneficial to assessing the response of rare earths to crop production and the eco-environmental safety. The interaction between rare earths and nitrogen and phosphorus in soil-plant system is briefly summarized,and it's put forward that the interaction between rare earths and nitrogen and phosphorus in the rhizophere of crop,surface layer of arable soil,and plant should be further investigated.

Key words: Rare earths, Nitrogen, Phosphorus, Soil-plant system, Interaction, Safety assessment, camera trap, artificial nest, nest predation, Syrmaticus reevesii.
