porosity of soil

基本解释

The studies of the soil properties suggested : (1) the bulk densities of the soils decreased and the general porosity of soil increased after amelioration;
两个试验田改良后土壤性质定量研究表明：（1）土壤容重降低，土壤总孔隙度增加；
Cropping patterns and position of slope have obvious affection to the development of the porosity of soil, while their interaction has not obvious affection.
方差分析结果，种植模式、坡位对土壤孔隙度发育有显著影响，而种植模式与坡位的交互作用对土壤孔隙度发育影响不显著。
On the basis of a high correlation coefficient of the relationship between dry bulk density and porosity of soil, the empirical formula of porosity of soil has been established.
过去我们利用土壤于容重和孔隙度之间的高相关关系，建立了一个土壤孔隙度经验公式。
