杉木木荷混交林生物量及营养元素积累的研究OA
A study of accumulation of biomasses and nutrition elements in mixed forests of Chinese fir (Cunninghamia lanceolata) and Schima superba
在福建宁化国有林场开展了12年生杉木纯林和杉木木荷混交林生物量、不同组分营养元素含量及积累量的研究，结果表明，混交林乔木层生物量高于纯林，灌木层、草本层和凋落物层生物量两种林分接近，混交林总生物量比纯林增加32.8%；混交林中杉木各器官多数营养元素含量高于纯林，但没有一致性的变化规律；混交林N、P、K、Ca和Mg积累量均高于纯林，混交林中这五种元素的积累量分别比纯林增加11.5%、15.6%、19.7%、30.7%和6.2%；因此，杉木木荷混交林…查看全部>>
Biomass, nutrient content and accumulation of different components in 12 years old Cunninghamia lanceolata monoculture plantation and C.lanceolata- Schima superba mixed plantation were studied in national forest farm of Ninghua, Fujian. The results showed that biomass of arbor layer in mixed plantation was higher than that of monoculture plantation, the biomass ofshrub layer, herb layer and litter layer was no great difference betweenmixed andmonoculture pla…查看全部>>
