The subsoiler drawn by walking tractor was designed, and the orchard contrast experiment was carried out. The result showed that the soil bulk density was decreased; the soil porosity condition was improved; the water content in soil was enhanced within 1m layer; the soil organic matter and soil total nitrogen also enhanced after subsoiled. The subsoiler special for walking tractor as a new type of orchard soil management measures in Weibei area will has good prospects for promotion.
