摘　　要：为探究常见有机物料对于土壤钾素形态有效性及对作物生长的影响,本文基于常用有机物料种类及施用方式,对当下有机物料包括秸秆、畜禽粪便、草木灰、生物炭、绿肥等的应用研究现状,以及对土壤中不同形态钾素的影响及肥效发挥情况进行综述,并提出了研究展望。有机物料在不同地区及土壤间作用效果差异显著,应根据实际情况开展还田应用。有机物料还田时需综合考虑土壤、作物的承载力,施用效果和还田成本等因素。In order to explore the effects of common organic materials on soil potassium form availability and crop growth,based on the types and application methods of common organic materials,this paper summarized the current application research status of organic materials,including straw,livestock manure,plant ash,biochar and green fertilizer,as well as the effects on different forms of potassium in soil and fertilizer efficiency,and put forward research prospect.There were significant differences in the effect of organic materials in different regions and soils.We should not only increase the amount of soil potassium,but also consider the bearing capacity of soil and crops,and comprehensively consider the application effect and return cost.
