以山西太岳山40年生油松(Pinus tabuliformis)人工林为研究对象,基于不同的森林经营措施,运用方差分析法分别探讨了油松人工林表层不同土壤厚度下的细根生物量和土壤养分含量之间的差异.结果表明:择伐林生长季表层细根生物量大于未择伐林,两者没有显著差异(P>0.05);择伐林平均单株表层细根生物量大于未择伐林,两者差异显著(P<0.05);择伐林表层土壤中的全氮含量、有机质含量、铵态氮含量高于未择伐林,差异显著(P<0.05);硝态氮含量和速效钾含量高于未择伐林,差异不显著(P>0.05);而择伐林表层土壤中的全磷含量低于未择伐林,差异显著(P<0.05).
Effect of selective logging on the surface fine root biomass and soil nutrient of Pinus tabulaeformis plantation in Taiyue mountain
To investigate the influence of selective logging on plantation development, surface fine root biomass and soil nutrient of 40-year-old Pinus tabulaeformis plantation were analyzed. The results showed that fine root biomass did not varied between selective logging and non-logging plantation during growing season ( P>0.05) . Biomass of surface fine root a single tree in selective logging plantation was greater than that of non-logging (P<0.05). Soil nutrient, including total nitrogen (P<0.05), organic matter(P<0.05) , ammonium nitrogen( P<0.05) , nitrate nitrogen and available potassium, were higher in the surface soil of selective logging plantation than non-logging. While total phosphorus was higher in non-logging than logging plantation ( P<0.05) .
