摘要: 【目的】针对干旱地区砂土地漏水漏肥现象以及市面上高分子保水产品成本较高、耐盐性差等问题,研究加入不同配比膨润土、甘草渣材料的砂土基质的保水性能,分析复合材料的最佳配比方案。【方法】 以天然、廉价、环保的钠基膨润土和甘草渣为原料,采用室内土柱模拟法,以纯砂土为对照,测量不同配比膨润土-甘草渣复合材料的砂土理化性质、吸水倍数和水分蒸发速率,表征复合材料的保水效应。【结果】 甘草渣的加入能够有效地调节了膨润土基本的理化性质。在充分灌溉条件下,复合材料重量占砂土20%T2处理吸水量较高,保水能力最佳,同复合材料重量占砂土15%T1处理差异不显著。若在水分短缺的环境下,复合材料重量占砂土20%的T2、T3组蒸发最慢,持水能力最佳。【结论】 在3组试验中,随着复合材料中膨润土比例的增加,其保水效果也相应增加,其保水效果由高到低依次为20%>15%>10%;其中在配比上选择使用膨润土和甘草渣总重量占砂土20%,且膨润土与甘草渣质量比1∶1.5最优。

Abstract: 【Objective】 In view of the water leakage and fertilizer leakage of sand land in arid area and the high cost and poor salt tolerance of high polymer water retention products on the market, soil pollution and so on, the water retention property of sand matrix with different proportions of bentonite and licorice residue was studied, and the optimum proportion scheme of composite material explored.【Method】Natural, inexpensive and environmentally friendly sodium bentonite and licorice residue were used as raw materials, the indoor soil column simulation method was applied and the pure sand was taken as contrast to measure the physicochemical properties, water absorption ratio and water evaporation rate of sandy soil with different proportions of bentonite-licorice residue composite, thus characterizinge the water retention effect of composite materials.【Result】The results showed that the addition of licorice residue could effectively regulate the basic physical and chemical properties of bentonite. Under the condition of sufficient irrigation, the weight of composite material accounted for 20% of the sand, and the water absorption capacity of T2 treatment was relatively high, and the water retention capacity was the best. There was no significant difference between T1 treatment in which the weight of composite material accounted for 15%. In the case of water shortage, T2 and T3 groups, which accounted for 20% of the weight of composite soil, had the slowest evaporation and the best water retention capacity.【Conclusion】In the three groups of experiments, with the increase of the proportion of bentonite in the composite material, its water retention effect is also increased correspondingly, and its water retention effect is 20%>15%>10% successively from high to low.The bentonite and licorice residue accounted for 20% of the total weight of sandy soil, and the bentonite and licorice residue weight ratio 1:1.5 is the best.
