| 摘 要： | 土壤总孔隙度是土壤物理的重要特征之一,据此可以计算土壤通气孔隙度,而且对于确定灌溉与排水也有重要的参考价值;在农业实践中,土壤通气性与土壤水分、导热性及作物养分等好多方面都有关,所以对总孔隙度的了解就很重要。

| Abstract: | According to 507 determinations of volumeweight, specific gravity and total porosity of five main soil types in Heilungkiang province, it was found that there is a high correlation between volume weight and total porosity, and the later can be calculated directly from volume weight with an empirical equation. |
