Title: Effect of Fertilizing on the Leaf Nutritive Element and Seedling Biomass of Potted Castanopsis fissa
Abstract: In the study in 2005~2006,311-A optimal mixed design fertilization on the leaf of Castanopsis fissa was adopted in the pot fertilization experiment.The relativity of dosage of N,P,K fertilizers and content of N,P,K nutritive element in the leaf of Castanopsis fissa seedling was analyzed.The regression equation model of biomass of Griffith oak and dosage of N,P,K fertilizer was established,with which the optimal fertilization matching was analyzed.The result showed that the nutritive element contents in leaf of Castanopsis fissa in seedling stage had positive correlation to N,P, K fertilizer as a whole,and that to K fertilizer was extremely remarkable.The effects of different fertilization matching on biomass of Griffith oak seedling were significantly different.The optimal fertilization matching was treatment No.8(N0.899 8,P2.206 8,K1.084 8 g/pot).Fertilizing according to the matching,the average optimal biomass of seedling in that year was up to 19.72 g,being 15.47 g higher than the worst treatment.
