安徽省萧县皇藏峪自然保护区森林土壤基本性质分析

对设于皇藏峪自然保护区内的3种森林植被下6块测试样地的土壤基本性质进行了分析比较,结果表明,栓皮栎林下土壤容重、硬度、饱和持水量、田间持水量等指标相对较大,而青檀林下土壤粘粒组成、孔隙度等指标相对较大;栓皮栎林下土壤呈弱酸性,而青檀林和黄连木、黄檀林下土壤呈碱性;在土壤养分方面,栓皮栎林下土壤水热条件较好,土壤有机质与氮、磷、钾等养分含量相对较高.

Analysis on Basic Characters of Forest Soil in Huangzangyu Nature Reserve in Xiaoxian County of Anhui Province

Comparison on soil basic characters of six sampling lands under three types of forest vegetation in Huangcangyu Nature Reserve in Anhui province shows that the indexes of soil bulk density,hardness,saturation moisture capacity,field capacity under Quercus variabilis forest are relatively great,while the index of soil clay particle compose and soil porosity under Pistacia chinensis forest are relatively great.The soil under the Quercus variabilis forest is partial to subacidity,while the soils under Pistacia chinensis and Dalbergia hupeana forest are partial to alkalescence.As for the soil nutrient,the hydrothermal condition is better and the soil organic matter and the content of N,P and K of the soil are comparatively high under the Quercus variabilis forest.
