土壤团聚体粒级分布是作物发芽和出苗以及根系发展的重要影响因子,其团聚作用在土壤固碳过程中具有不可或缺的贡献,团聚体的结构性破坏将导致土壤有机质的流失,而团聚体稳定性直接影响着土壤侵蚀程度[1]。常规耕作表层土壤易受外界因素(如温度和水分条件)的影响。这不仅使土壤 Particle size distribution of soil aggregates is an important factor affecting crop germination and emergence as well as root development. Its agglomeration has an indispensable contribution to soil carbon sequestration. The structural destruction of aggregates will lead to the loss of soil organic matter, Body stability directly affects the degree of soil erosion [1]. Conventional tillage topsoil is susceptible to external factors such as temperature and moisture conditions. This not only makes the soil
