摘要
自然土壤酸化是一个缓慢的过程,但是农田土壤因频繁的人类活动加速了这一过程,从而给农田土壤-微生物-作物系统带来一系列的负面影响.论文从大气酸沉降、施肥和管理方式、种植作物以及作物移除四个方面介绍了农田土壤酸化的主要原因;重点阐述了土壤酸化对农田土壤肥力、土壤盐基离子以及土壤酸缓冲体系的影响.总结了酸性农田土壤对土壤细菌群落结构、功能性微生物(如氨氧化古菌和氨氧化细菌等)群落结构以及土传病害的影响;分析了土壤酸化对作物的毒害作用,如造成农作物减产、迫使作物根系受到铝毒害等;从外源添加物减缓土壤酸化角度,论述了可持续利用酸性土壤的策略,提出了土壤酸化后的改良措施,展望了土壤酸化需进一步探究的课题.
Abstract
Soil acidification is a natural and slow process in natural conditions.However,intensive cultivations and anthropogenic activities accelerate this process and causing serious adverse impacts on soil-microbial-crop consortium in farmland.In our review,firstly,the main reasons for soil acidification were summarized,such as atmospheric acid deposition,the application of fertilizers,soil managements,crop types and the removal of crop residues.Secondly,the effects of soil acidification on soil fertility,soil base cations,soil pH buffering capacity were illustrated and the responses of soil bacterial communities,functional microbial communities(e.g.ammonia-oxidizing archaea and ammonia-oxidizing bacteria)and soil-born diseases to soil acidification were summarized.Then the possible consequences of soil acidity on crop yield loss and the increasing aluminum toxicity in crop roots were analyzed.Finally,the sustainable strategies for acidic soil use from the perspective of using exogenous amendments were discussed and proposed suggestions for the improvement and remediation of acidified soils,and the future research avenue in soil acidification was put forward.
