土壤饱和含水量

与对照相比，施加PAM不仅可以增加土壤的饱和含水量，而且能有效抑制土壤水分蒸发，效果与PAM溶液施用浓度呈正比。

Compared with the control , applying the PAM not only can be saturated water content increased with soil , but also can effectively restrain soil water evaporation , and the effect of PAM solution concentration was proportional to the .

连续施用棉籽饼、棉茎秆及化肥配施对土壤酶活性、土壤容重、饱和含水量、总孔隙度等物理性质也有良好的改善和提高作用。

Then the continuous application of cotton seed manure and cotton stalk together with combined application of chemical fertilizers could improve chemical properties of soil , such as enzymatic activity , unit weight , saturated water content , total porosity and etc.

研究冻融土壤的水盐分布格局表明土壤饱和含水量线呈现>形分布结构，总盐分含量和碱化度（ESP）的等值线呈∧形分布结构。

The distribution pattern was studied scientifically . It reveal that the structure of contour of saturated soil water presents like > and that of total salt amount and ESP looks like ∧ .

施用PAM后对土壤容重及土壤总孔隙度具有调节作用，土壤饱和含水量和田间持水量均有所增大，并显示出较强的抗蒸保墒效果。

When using PAM , the soil saturation content and soil field water-content can increase and the treatment can prevent the evaporation of soil water , so the water content of the treatment is higher than control .

不同林分的土壤容重、总孔隙度、土壤田间持水量、土壤饱和含水量均随土层增加有递变的规律，且不同林分间有差异。

Soil bulk density , total porosity , field capacity , and saturated soil moisture were increased as soil depth increasing , and difference was found among different poplar plantations .

在地形上，土壤物理性质具有明显的垂直分布规律，阴坡除土壤容重外，饱和含水量、田间持水量和萎蔫湿度均大于阳坡；

The soil physical properties have obvious vertical distribution characteristic in the slope .
