Abstract:
Castanopsis fissa,
Acacia auriculiformis,
Artocarpus nitidus subsp.
lingnanensis and
Camellia oleifera were planted among rows and lines in one part of pure
Pinus caribaea stand(G
1),
Schima superba, Symplocos lancifolia, Carallia brachiata and
Camellia oleifera were planted in another part of the pure
Pinus caribaea stand (G
2). The nutrient and photosynthetic characteristics of broad-leaved tree species in these 2 remodeling modes were studied. Results showed that N, P, K concentrations in leaves of
Acacia auriculiformis and
Artocarpus nitidus subsp.
lingnanensis at G
1 plot were high and the same as leaves of
Carallia brachiata among at G
2 plot. Net photosynthetic rate, stomatal conductance, intercellular CO
2 concentration and transpiration rate decreased in the order of
Acacia auriculiformis >
Artocarpus nitidus subsp.
lingnanensis >
Castanopsis fissa >
Camellia oleifera at G
1 plot, and in the order of
Schima superba >
Camellia oleifera >
Carallia brachiata >
Symplocos lancifolia at G
2 plot. The above results indicated that
Acacia auriculiformis,
Artocarpus nitidus subsp.
lingnanensis and
Schima superba were excellent tree species for stand transformation.
