土壤团粒结构形成机制及其稳定性影响因素研究

Study on the Formation Mechanism of Soil Aggregate Structure and the Influencing Factors on Its Stability

土壤团粒是土壤结构体常见形态,直接影响土壤的水、气、热、肥等因素,是评价土壤结构性优劣的重要指标。本文针对土壤团粒结构体的形成机制及其稳定性影响因素,结合教材相关内容和近年来国内外土壤团聚体研究成果进行整理归纳和比较分析,总结目前国内外在土壤团聚体研究方面呈现的特点,旨在提高教学实效的同时为土壤团聚体的深入研究提供一定的参考。

Soil aggregate is a common form of soil structure,which directly affects soil water,air,heat,fertilizer and other factors,and is an important index to evaluate the quality of soil structure.This paper summarizes the characteristics of soil aggregate research at home and abroad,based on the formation mechanism of soil aggregate structure and the factors influencing stability,combined with the relevant content in textbooks and the research results of soil aggregates at home and abroad in recent years,in order to improve the teaching effectiveness and provide some reference for the in-depth study of soil aggregates.
