摘  要:
通过对套种圆叶决明的油茶园土壤作为期3年的理化性质及流失量动态变化研究,初步了解茶园套种圆叶决明的水土保持效果,结果表明:1土壤养分随时间变化增幅明显;2土壤质地随时间变化进一步改善,具体表现在其容重降低、孔隙度和持水量增加;3土壤中砂砾含量逐年降低,粉粒含量逐年上升,土壤机械组成更趋合理;4土壤流失量呈逐年降低趋势。表明油茶园套种圆叶决明具有良好的水土保持效果。

摘  要:
Three- year dynamic changes study was conducted on physical and chemical properties and erosion volume of soil in the oil tea camellia garden intercropping with the Chamaecrista rotundifolia so that to know the soil conservation effect. The results showed that: 1) soil nutrient increases obviously followed with the time changes; 2) soil texture is further improved over time,including the reduction of bulk density,increase of the porosity and moisture capacity; 3) sand and gravel content gradually decrease while the silt content gradually increase by years,making the soil mechanical composition more reasonable; and 4) soil loss appear the decrease trend by years. All these indicated that Chamaecrista rotundifolia has good effect of soil conservation on the soil environment in the oil tea camellia garden.
