摘　　要：应用高吸水树脂改良侵蚀性土壤物理性状的结果表明 :高吸水树脂可以改善土壤结构 ,减小土壤容重 ,增加土壤空隙度 ,改良通气性 ,提高保水率 .在侵蚀性土壤中加入 0 .2 5 % -1 .0 0 %质量分数的高吸水树脂 ,土壤含水量可提高 1 -2倍 ,土壤团聚体数量增加 1 -4倍 .加入 0 .2 5 % -0 .5 0 %质量分数的高吸水树脂可以提高土壤稳定渗透率 ,防止土壤板结 ;加入1 .0 0Super water absorbent resin was applied to improve physical properties of eroded soil. In details, the resin improved soil structure, decreased soil bulk density, increased soil porosity, aeration and water retention capacity. Mixing 0.25%- 1.00% mass fraction of resin into eroded soil, the water retention capacities of soil increased by 1-2 times, and the aggregation increased by 1-4 times. Adding 0.25%-0.50% mass fraction of resin improved soil permeability, but 1.00% mass fraction of resin prevented water leaking into deep soil.
