Abstract:

The experiment was conducted to study the water-conserving ability of multifunctional water absorbant in different soils on Loess Plateau．The results indicated that in the aspect of soil water holding capability the absorbant was most effective to Heilu soil but not clearly effective to Lou soil and loessial soil．In the aspect of soil water conducting capability the absorbant was most effective to loessial soil and the saturated hydraulic conductivity increased with the increase of dosage of the absorbant；it was also somewhat effective to loessial soil；but when it was applied to Lou soil the saturated hydraulic conductivity was reduced．In the aspect of soil evaporation resistance the absorbant was clearly effective to all kinds of soil and the evaporation rate tended to reduce with the increase of its dosage．
