针对干旱区水资源匮乏,城市绿地土壤保水性差这一现状,选取片石、陶粒、沙石、树皮、木格等材料,采用覆盖法,开展不同覆盖物对土壤保水效果的试验研究,结果表明:地表覆盖保水可有效减缓土壤水分向地表流动,所选取的5种覆盖材料的保水性能都优于空白对照裸地,其中陶粒最为明显。
In this paper, the study aims at lacking of water resources in arid area and the actuality of the bad performance of the city garden soil, choosing these mulches such as slip stone, clay aggregate, sand and stone, bark, wooden reseau and so on, adopting the covered method, developing experiment on the effects of different mulches on soil water- saving.
