无结构土壤 meaning in Chinese

non-structural soil
structurele oil
structureless soil

Because these factors make change more often , soil time space variability is more bigger . the relationship of single factor between soil water infiltration capacities and certain influencing factor could be established quantitatively by means of soil water infiltration tests in indoor , there is negative correlation relation between soil water infiltration capacities and soil structure . there is negative correlation relation in high grit content and low physical clay content soil , and second - degree polynomial relation in high physical clay content junk structural soil between soil water infiltration capacities and soil moisture
由于这些因素在时刻发生变化，使得土壤的时空变异性较大，只能用室内土壤水分入渗试验来定量确定土壤水分入渗能力与某些影响因素之间的单因子相关关系，土壤水分入渗能力与土壤结构之间呈负相关关系，土壤水分入渗能力与土壤含水量之间在土壤砂粒含量高，物理性粘粒含量低的无结构土壤中呈负相关关系，在物理性粘粒含量高的团粒结构土壤中呈二次多项式关系。
