摘要
本文对我国北方黑土、草甸黑土和白浆土,中部棕壤,南方红壤,西部钙层土,以及多种水稻土等肥地同瘦地间的土体构造进行了分析比较,并初步拟订了水田、无灌溉旱田和灌溉旱田良好土体构造标准,可作为土壤培肥的参考。
The composition of a soil pore space is the objective reflection of pedon structure. Its total pore space increases with the decrease of its dispersed particles or the increase of aggregate particle; Space occupied by wilting water and capillary space increase with the decrease of particles; Aeration space increases with the increase of particles. Accordins to the difference of mechanical compositions and the composition of pore spaces in soil, We can distinguish the different types of pedon structure.
