贵州地产玄参土壤团聚体特征

Characteristics of Soil Aggregates of Scrophulariaceaein Guizhou

为了解贵州地产玄参种植土壤团聚体特征的,采集贵州地产玄参种植土壤,探讨了贵州地产玄参种植土壤机械性团聚与水稳性团聚体含量及土壤团聚体稳定性特征。结果表明:机械稳定性团聚体以>5mm为主,水稳定性团聚体以<0.25mm为主。>0.25mm机械稳定性团聚达到97.28%,>0.25mm水稳定性团聚达为51.64%。>5mm土壤团聚体破坏率最高,>1mm土壤团聚体破坏率其次。贵州地产玄参土壤团聚性较强,土壤结构良好。

In order to understand the characteristics of soil aggregates of Scrophulariaceae, the planting soil of Scrophulariaceae in Guizhou was collected, the content of soil mechanical property and water stable aggregates and soil aggregate stability in Guizhou was discussed. The results showed that the mechanical stability of the aggregates was 〉5mm, and the water stable aggregates was〈0.25mm. The mechanical stability of〉0. 25mm aggregates was 97.28 %, the water stable aggregates of 〉0. 25mm was 51.64% . The soil aggregate destruction rate of〉5mm was the highest, and the soil aggregate destruction rate of 1mm was second. The soil aggregationin Scrophulariaceae planting field of Guizhou was strong, the soil structure was well.
