摘　　要：提升土壤肥力是维持农业可持续发展和保障我国粮食安全的重要保证。为了从根本上实现基础地力相对较差地块的土壤肥力提升目标,本研究通过对土壤肥力提升原理与技术研究进展的系统总结,围绕土壤肥力概念、土壤肥力评价指标与方法、土壤肥力与作物产量的关系、土壤肥力提升的技术措施和研究展望5个方面进行了详细的阐述。分析表明,有机肥物料,尤其是加工后的生物炭和商品有机肥的施用,是我国现阶段提升土壤肥力的关键技术措施,而分类建立生物炭和有机肥生产和施用的技术与标准,发展有机无机配施理论,则是今后较长一段时间内实现土壤肥力提升的重要研究方向。Intensive agriculture and other anthropogenic activities have led to soil degradation in many regions across China.Improving soil fertility and restoring soil functions is important to maintain sustainable agricultural production and safeguard food supply in China.In this paper,we systematically review the methods and technologies developed over the past decades to improvesoil fertility,which includes the concept of soil fertility,index and methods for evaluating soil fertility,the relationship between soil fertility and crop yield,as well as the prospects of soil fertility improvement.In particular,we analyze and discuss the applications of various organic materials including processed biochar and commodity organic fertilizers for improving soil fertility and their efficacy for different soils.We conclude that establishing standards of biochar and organic fertilizers and their application as soil improvers will be an important research area for long-term improvement of soil fertility.
