Pneumatic subsoiling is a new subsoiling technology which uses the pneumatic fracturing principle. To conduct a research on the influence rules of subsoiling pressure to subsoiling quality, the method combining the soil resistivity test and CFD simulation test will be adopted to carry out a pneumatic subsoiling test through taking the increasing rate of soil porosity and soil surface uplift as evaluation index. The test results indicate that after pneumatic subsoiling, the soil porosity of plow pan increases obviously under different subsoiling pneumatic, effective break the plow pan; with the increase of bulk density of plow pan, the spread of the high pressure gas upwards in the plow pan shows a weakening trend and its spread towards horizontal direction shows a enhancing trend; for the plow pan with larger bulk density, the increasing rate of soil porosity and soil surface uplift will increase with the increasing of subsoiling pneumatic accordingly and for the plow pan with smaller bulk density, its regularity is not obvious. Simultaneously, the subsoiling pneumatic and its technical parameters fit for plow pan with different bulk density will be obtained to provide a basis for in-depth research of pneumatic subsoiling technology and development of Pneumatic subsoiling machine.
