摘　　要：荒漠化土壤恢复与改良急需解决的两个关健问题是土壤保水保肥能力的提高和土壤中有植物生长所需的养分。为此,用高分子黏结剂将高吸水树脂和高分子化肥有机地结合起来,制备成多功能高分子复合材料用于沙土的改良。对多功能高分子复合材料的性能测定和应用于沙土种植试验的结果表明:在沙土中施用0.5%的多功能高分子复合材料,可提高沙地土壤的保水能力和土壤肥力,使土壤环境得到改善、种植的植物生产量获得大幅度增加。The two key issues urgently need to be solved are capability increase of water conservation and fertility retention of soil and enough nutritional substance in soil for plant growth in rehabilitation and improvement of desertification soil.Thus,it prepares multifunctional composite materials for improving sand soil through organically combining super-absorbent resin with polymer fertilizer by macromolecule bond.The outcomes of performance test of composite materials and results of plant growth in desertification soil show that using 0.5% multifunctional composite material into sand soil can increase the capability of water conservation and soil fertility,improve soil environment and greatly increase the output of plants.
