The coefficient of variation of saturated water content decreased with the depth of profile. The coefficient of variation of bulk density and field capacity fluctuate with depth of soil.

饱和含水量的变异系数都随深度的增加逐渐降低，含水量、容重和田闷持水量的变异系数随深度的呈波动变化。

The results of this analysis showed a significant correlation of water uptake rate with soil profile water content and root weight density.

结果表明：紫花苜蓿根系吸水速率与土壤剖面含水量和根重密度密切相关。
