中文摘要	采用室内土柱试验,研究了BJ2101XM型保水剂3种施用量及沟施和混施的方法对典型半干旱砂性土壤的入渗和蒸发的影响。结果表明: 施用后,入渗速率最大降至对照的0.77(混施)和0.89(沟施); 相同初始含水率下,连续蒸发下,土壤含水率均高于对照,其中混施6kg /亩的各层含水率是对照的1.3 - 39倍,其15cm处提高了42%; 混施比沟施减少了6 - 25%的土壤蒸发量。
英文摘要	In this research,we used the soil column simulated experiment with super absorbent polymer (BJ2101XM) to improve the structure of typical sandy soil from semi - arid areas,and discussed its effects on soil water infiltration and evaporation. It set up 3 levels of SAP and two application methods (furrowed and mixed applying). The analysis results show that the best infiltration rates of SAP treatment were down to 77% and 89% of the control (CK). Under the same initial soil water content, from continuously evaporating and observing,soil water content of SAP treated soil were all higher than CK. The most pronounced group was mixed 90kg /hm2 with mixed application,and its soil water of each layer was up 1.3 - 39 times than CK’ s. At 15 cm depth,the increasing ratio was up to 42%. Mixed applying significantly decreased water evaporation (6 - 25% lower than CK) and increased soil water retention.
