Abstract

By taking soil of Davidia involucrata wild population in Piankou as the research object,studies were made of soil physical and chemical properties (soil bulk density,soil porosity percentage,pH value, organic matter,total nitrogen,hydrolysis of N,total phosphor,available phosphorus). The results revealed that the pH value of Davidia involucrata soil in Piankou was between 4.93 and 6.57,acidic; the average value of soil bulk density was 1.27 g·cm^-3,and the average soil porosity was 52.22%,thus being suitable for the growth of Davidia involucrata; soil organic matter,total nitrogen,available nitrogen,total phosphorus,and available phosphorus content had the tendency of becoming less with the deepening of the soil layer,whose contents were generally low,especially soil available phosphorus content was very poor.
