The simulation rainfall and the field experiments have been madein this article, and the technology of bulk subsoil was applied in bess plateau to observe the effectfor increasing the infiltration and the affection for the growth of Caragana.

• 本文通过模拟降水试验和田间试验探讨了不同雨强和降水时间下降水入渗、集蓄特点，对全方位深松技术对土壤入渗性能的影响做了研究，考虑了土壤结皮、植被和耕作方式等因素的影响，并将其归结为对导水率的影响，推导出改进的Green-Ampt公式，并对试验结果进行了模拟计算。
