农田土壤团聚体研究进展

摘要

土壤团聚体是土壤的重要组成部分,影响着土壤中养分和水分的含量及作物的生长状况,是土壤肥力和结构的重要指标.该文综合回顾了土壤团聚体的形成机制,团聚体胶结剂、农田管理措施对土壤团聚体的重要影响等方面的研究进展,发现并指出其中存在问题并为其进一步研究指出方向.%Soil aggregates, as an important component of soil, have an effect on the content of the nutrient, moisture, and the condition of crop growth. Soil aggregate is also an important index of soil fertility and soil structure. This paper comprehensively reviewed the research about the formation mechanism of soil aggregation, the effect on the soil aggregate of the management and aggregates cementing agent. Then the exiseing problems in the study on field soil aggregate and the directions of further research were pointed .out.
