Nutrient and Photosynthetic Characteristics of Broadleaved Tree Species in Mixed Growth of A Pure Pinus caribaea Plantation
摘要
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(G1),Schima superba,Symplocos lan-cifolia,Carallia brachiata and Camellia oleifera were planted in another part of the pure Pinus caribaea stand (G2).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 G1plot were high and the same as leaves of Carallia brachiata among at G2plot. Net photosynthetic rate,stomatal conductance,intercellular CO2concentration and transpiration rate decreased in the order of Acacia auriculiformis>Artocarpus nitidus subsp. lingnanensis>Castanopsis fissa>Camellia oleifera at G1plot, and in the order of Schima superba>Camellia oleifera>Carallia brachiata>Symplocos lancifolia at G2plot. The above results indicated that Acacia auriculiformis, Artocarpus nitidus subsp. lingnanensis and Schima superba were excellent tree species for stand transformation.关键词
