摘    要:对典型黑土的水分物理性质进行了测定和分析。结果表明,土壤容重随土层深度的增加呈增大趋势;土壤孔隙度随土层深度的增加而减小;整个土壤层次可划分为0~50cm的高孔隙度区和50~100cm的低孔隙度区;土壤持水性能随土层深度的增加而减小。

关 键 词:典型黑土  水分物理性质  垂直变化

Institution:CHEN Min et al (Northeast Forestry University,Harbin,Heilongjiang 150040)
Abstract:The physical properties of water in typical black soil were measured and analyzed. The results showed that the soil bulk density showed increasing trend with the increase of soil depth. Soil porosity was decreased with the increase of soil depth. The whole soil layers could be divided into high porosity zone of 0-50 cm and low porosity zone of 50-100 cm. Soil water holding capacity was decreased with the increase of soil depth.
Keywords:Typical black soil  Water physical properties  Vertical change
