土壤总孔隙度是影响土壤肥力状况的主要物理特性之一。高产稳产的土壤,不但有合适的大小孔隙比,而且要有足量的总孔隙度。土壤总孔隙度是计算土壤固相、液相、气相的主要数据,是高产稳产土壤的重要指标,是评价农机具耕作质量,确定耕作、灌溉、排水等农业生产措 Total soil porosity is one of the major physical properties that affect soil fertility. High and stable yield of soil, not only has the appropriate size of the void ratio, but also to have a sufficient amount of total porosity. The total soil porosity is the main data used to calculate the solid, liquid and gas phases of soils. It is an important index of soil with high and stable yield. It is an important measure to evaluate the quality of agricultural implements and to determine the agricultural measures such as farming, irrigation and drainage
