摘要
为探索贵州地产玄参不同利用方式下土壤物理特征,采集贵州地产玄参种植土壤,探讨了贵州地产玄参不同利用方式下土壤机械组成、土壤质地及土壤孔隙度特征。结果表明:3种利用方式下土壤均以粉粒为主,3种利用方式下土壤质地属于砂壤土。玄参土壤总孔隙度为60.14%,党参土壤总孔隙度为51.93%,林地土壤总孔隙度为63.80%。土壤毛管孔隙度表现为玄参>党参>林地,土壤非毛管孔隙度为玄参>党参>林地。
To explore the soil physical characteristics under different land usage patterns of Scrophulariaceae in Guizhou ,the planting soil of Scrophulariaceae in Guizhou was collected, soil mechanical composition, soil texture and soil porosity under different utilization patterns of Scrophulariaceae in Guizhou were discussed. The results showed that the soil quality under the 3 kinds of methods were mainly based on the silt, the soil texture under the 3 kinds of methods was sandy loam soil. The total porosity of figwort root soil was 60.14%, the total porosity of soil Codonopsis pilosula was 51.93%, the total porosity of soil forest was 63.80%. The soil porosity was Scrophulariaceae〉Codonopsis pilosula 〉woodland, soil non capillary porosity was Scrophulariaceae〉Codonopsis pilosula 〉woodland.
