常绿阔叶林迹地经营不同人工林类型使土壤容重增加了0.06~0.31g/cm3,土壤毛管孔限度、非毛管孔隙度、总孔限度分别降低了4.59~7.21百分点、3.95~10.98百分点、11.54~16.32百分点。6种森林类型土壤腐殖质、全N、全P含量均为A层高于B层,其中土壤腐殖质、全N平均含量顺序为:木荷与杉木混交>鹅掌楸与杉木混交>常绿阔叶林>杉木>鹅掌楸>马尾松。土壤腐殖质与土壤全队总酚含量之间,全N与总酚含量之间相关系数分别为0.990、0.892、0.883,达权显著相关。6种森林类型中除马尾松林地土壤腐殖质HA/FA<1外,其余5种森林土壤均为HA/FA>1。木荷与杉木混交、鹅掌楸与杉木混交林土壤肥力明显好于单一树种栽培,而且有效地抑制了土壤多酚氧化酶活性。
In the evergreen broad-leaved forest, the soil bulk density was increased by 0.06 ~ 0.31g / cm3 under different plantation types. The capillary porosity limit, non-capillary porosity and total pore porosity decreased by 4.59 ~ 7.21%, 3.95 ~ 10.98% and 11.54% ~ 16.32 percentage points. The contents of soil humus, total N and total P in the six forest types were higher than that in layer B, and the order of soil humus and total N was as follows: mixed with Chinese fir and Chinese fir> Liriodendron hybrids with Chinese fir> evergreen broadleaf Lin> Chinese fir> Liriodendron> Masson pine. The correlation coefficient between total humus and soil total phenolic content, total N and total phenolic content were 0.990, 0.892 and 0.883, respectively. Among the six forest types except the soil humus HA / FA <1 in Masson pine forest, the other five kinds of forest soil all had HA / FA> 1. The soil fertility of mixed Schima superba and Cunninghamia lanceolata plantation, Liriodendron chinensis and Cunninghamia lanceolata plantation was significantly better than single tree species cultivation, and the polyphenol oxidase activity of soil was effectively inhibited.
