Title: Soil Physical Property and Real-time Decision Method of Soil Moisture State in Heilongjiang Dry Area
Abstract: The main farmland soil types in Heilongjiang province are of white pulp soil,black soil,Chernozem,meadow soil.In this study,according the actual value of dry soil density,capacity soil moisture constant by weight,soil porosity with different soil in different vertical layers,applying statistical analysis method,to solve the internal relations among the three index above.The results show that in the cultivated land of Heilongjiang province the dry soil density was significant correlation to the soil porosity.The greater the dry soil density is,the smaller the soil porosity.The capacity soil moisture constant by weight also shows significant correlation.Thus it determines the relationship of the dry soil density and moisture content by volume,and be generated to easily make certain the drought situation accord with the measured soil moisture by volume.
