土壤透气性

无结构土壤透气性的初步研究

A primary study of permeability of structureless soil to air

粘土颗粒群粒度分布分形维与土壤透气性关系

Correlation of Clays Particle Group Size Distribution Fractal Dimension and Soils ' Air Permeability

排水不良能减低土壤的透气性，使根死亡。

Poor drainage causes deficient soil aeration and death of the roots .

育苗基质要求土壤疏松。透气性好。保水保肥。干净无病害，肥力较好。

Soil of requirement of grow seedlings matrix loose , permeability is good , protect water fat , clean without disease , fertility is better .

试验表明，梨园种植这些饲草，可控制杂草的滋生，改善土壤理化性状，增加土壤透气性及有机质含量，增加土壤水分，调节地温；

The results indicated that these forages could control weeds , improve the physical and chemical features of soil , increase the soil organic matter content , regulate the soil temperature .

地块的土壤容重减少，提高土壤膨松度，增强土壤透气性。

The soil bulk reduced , the soil porosity and permeability improved .

土壤CO2浓度随土层的加深迅速升高，主要与土壤透气性有关。

Soil CO2 concentration increased sharply with soil depth , this might be ascribed to the very low CO2 diffusivity at deep soils .
