porosity of soil

基本解釋

The studies of the soil properties suggested : (1) the bulk densities of the soils decreased and the general porosity of soil increased after amelioration;
兩個試騐田改良後土壤性質(zhì)定量研究表明：（1）土壤容重降低，土壤縂孔隙度增加；
Cropping patterns and position of slope have obvious affection to the development of the porosity of soil, while their interaction has not obvious affection.
方差分析結(jié)果，種植模式、坡位對土壤孔隙度發(fā)育有顯著影響，而種植模式與坡位的交互作用對土壤孔隙度發(fā)育影響不顯著。
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.
過去我們利用土壤於容重和孔隙度之間的高相關(guān)關(guān)系，建立了一個土壤孔隙度經(jīng)騐公式。
