研究分析了湖南省（分布在１７县）的传统名优茶产地（下称名优茶区）９２个土壤样本的物理性状。结果表明，名优茶区土壤有比较深厚疏松的表土层。表土层厚度２５ｃｍ以上，容重１．０～１．２ｇ／ｃｍ３，团粒结构，大于０．５ｍｍ的团粒含量５５％以上。孔隙度大于５０％，整个剖面无障碍性层次，有效土层７０ｃｍ；质地多为重壤土。土壤物理性粘粒与物理性砂粒含量大致相当，粘粒、粉粒、砂粒之比为１．０∶１．５∶１．５，且大于０．２５ｍｍ的中砂粒级分占１５．０％以上；表土层土壤固相比例低于４５％，液相与气相合占５５％，液相稍多于气相；毛管持水量和饱和含量分别在３５％和４０％以上。心土层的固相比例虽有所增大，但低于５０％，毛管持水量和饱和含水量一般在３０％和３５％
The physical characteristics of 92 soil samples from Hunan famous traditional tea producing areas (named as Mingyoucha) were analyzed. The results showed that the famous tea area soil has a relatively deep and loose topsoil. Topsoil thickness 25cm above, bulk density of 1.0 ~ 1.2g / cm3, aggregate structure, more than 0.5mm of the pellet content of 55% or more. Porosity greater than 50%, the entire cross-sectional accessibility level, effective soil 70cm; texture mostly heavy loam. Soil physical clay and physical sand content is roughly the same, clay, silt, sand ratio of 1.0: 1.5: 1.5, and greater than 0.25mm of sand accounted for 15.0% . The ratio of soil solid phase in topsoil was less than 45%, liquid phase and gas phase accounted for 55%, liquid phase was slightly more than gas phase. Capillary moisture content and saturated content were above 35% and 40% respectively. Although the ratio of solid phase in the soil layer increases, but less than 50%, capillary water content and saturated water content is generally 30% and 35%
