Specific surface of soil and fine pore property of soil are important factor to the water retentivity of soil.In this time, I have investigated the relation between fine pore property of soil and water retentivity.The result were as follows 1. Quantity and quality of fine pore are affected by the soil texture, organic matter content and origin of soil. 2. The moisture volume percentage in each water constants has a high positive relativity to total fine pore content. 3. I have shown that the moisture volume percentage for certain pF-values <3.0 can be estimated from the value of total fine pore content of soil.

土壤的比表面积和土壤的细孔性质是影响土壤持水性的重要因素，本文对土壤的细孔性质与土壤持水性的关系进行了研究，结果表明：1.土壤的细孔性质与土壤的持水性有密切的关系。细孔隙的数量和质量受土壤质地、有机质含量和土壤来源的影响。2.各水常数中的水分体积百分比与总细孔含量有很高的正相关性。3.我已经证明，对于某些pF值<3.0的含水量百分比可以从土壤的总细孔含量值中估算出来。
