Ecological and Biological Characteristics of Bauhinia corymbosa
首冠藤的生态生物学特征

The physiological and ecological characteristics,and nutrient utilization of Bauhinia corymbosa were studied by plot investigation.The species is a heliophyte liana and distributes mainly in open forest fringe,hillside,and village side in tropical and subtropical areas,and grow well on the red soil and lateritic red soil.The average photosynthetic rate,stomatal conductance and transpiration rate were 3.306 μmol m~(-2)s~(-1),0.25 mol m~(-2)s~(-1)and 4.10 mmol m~(-2)s~(-1),respectively.The weighted nutrient contents of N,P,K,Ca,Na,and Mg in B.corymbosa were 1.1 1%,0.09%,0.56%,0.86%,0.21%and 0.06%,respectively.The nutrient utilization efficiency of B.corymbosa is high and N content in leaf is the highest,and do Na content in branch,P and Mg contents in root,The ecological and biological characteristics of B. corymbosa were beneficial to growing,climbing and adapting to environment.
