摘  要：
对PAM和SAP交并施用对旱区坡地固土截水的影响进行初步测定。PAM和SAP都是很好的土壤改良剂。使用PAM可以显著降低土壤结皮,减少地表径流和土壤侵蚀。SAP可以提高土壤的保水性,改善土壤结构。采用两种SAP施用方式:SAP(0~20cm)混施和SAP(20cm)层施。土槽装填好后,将PAM均匀撒施在土壤表层。将土槽置于调整好角度的支架上。降雨10min,湿润土壤。静置1d后再进行试验。试验结果表明PAM和SAP交并施用可以明显增强土壤的固土截水能力。当SAP混施时,PAM施用量的影响比SAP显著。而SAP层施时,SAP施用量的变化对土壤的固土截水能力没有影响,但PAM依然影响很大。相同PAM和SAP施用量的情况下,SAP混施比层施时减少水土流失量、土壤侵蚀量、地表径流量更大。

摘  要：
In this paper,the effect of Polyacrylamide and Super Absorbent Polymer on keeping soil and water of sloping lands in dryland areas has been studied.Polyacrylamide and Super Absorbent Polymer are good soil conditioner.Using PAM can significantly reduce soil crust、surface runoff and soil erosion.SAP can improve the water maintenance and structure.Using two methods of SAP application:SAP mixed with soil(0~20cm)and SAP applying in soil layer(20cm).After filling the soil bin,sprinkle PAM uniformity on the soil surface.The soil bin is arranged on the bracket which had been adjusted to the good angle and rain for 10 minutes to wet the soil.After standing for one day,we go to carry out the experiment.It shows that PAM and SAP can enhance the soil's ability of keeping soil and water.When SAP is mixed with soil,the effect of PAM dosage was significantly more than that of SAP.When SAP is applying in soil layer,changing in the amount of SAP had no effect on the soil's ability of keeping soil and water.But PAM still had great influence.When the application amount of PAM and SAP was same,mixing with soil can reduce the water and soil loss amount,soil erosion amount and surface runoff more than applying in soil layer.
