本文就土壤通气孔隙的概念及测定方法,通过对不同耕作制度下土样的大量分析和研究,提出了“潜在通气孔隙度”和“实际通气孔隙度”的新概念。“潜在通气孔隙度”是指在吸力平板仪上某一吸力下测得的大于某一孔径的空隙度,它代表土壤可能存在的最大通气孔隙度;“实际通气孔隙度”是根据“潜在通气孔隙度”、总孔隙度和田间实际合水量而求得的空隙度,它代表在田间实际水分状况下能真正起到通气作用的孔隙度。 In this paper, the concepts and determination methods of soil aeration pores were proposed. The new concepts of “potential aeration porosity” and “actual aeration porosity” were put forward through extensive analysis and study of soil samples under different farming systems. “Potential Volatility Porosity” refers to the porosity greater than a certain pore size measured at a suction on a suction plate, which represents the maximum possible aeration porosity of the soil. The “actual aeration porosity” is based on “potential aeration Porosity, ”“ Total Porosity, ”and“ Actual Field Water Consolidation, ”represent the porosity that can actually effect aeration in real field conditions.
