土壤孔隙性

In the laboratory , it has been found that the incorporation of straw into the soil increased the coefficient of saturated soil penetration , thus the macro - porosity of soil
实验室测定表明，在土壤中加入稻草可以增加土壤的饱和透水系数，这说明土壤的大孔隙增加了。
The results showed that the order of porosity was h1 < t2 < h2 , and porosity sharply descended during 10min , then there was little change in the porosity of soils with rainfall going on
试用后，初步认为采用最大释然法分析总孔隙度可以获得结果，与容重法测的孔隙相比，结果偏小。
The results showed that straw returning had not significantly increased the content of organic matter except for the treatment b . the treatments of straw - returning had a tendency to decrease the bulk density of soil in a no significant manner , thus increased the porosity of soil
实验室内对土壤微团聚体的分析还表明，随着稻草的施入，土壤的微团聚化程度得到了提高，但全量整株还田处理与其它处理之间差异很小。
