Effect of tree-controlling on nutrient of Camellia oleifera

To explore the process of growth and development of Camellia oleifera tree control technology (pruning ) on Camellia carbohydrates content,protein content and other changes,for the efficient management of C.oleifera body to provide data support and scientific basis .In this study during shoot growth,fruit development period,dormant period 3 periods on Camellia adult trees to fine trimming and pruning,simplified trimming and pruning,extensive trimming and pruning and control 4 modes of tree restructuring of its tree vivo total soluble sugar,soluble starch,soluble protein content and the degree of sucrose synthase activity,nitrate reductase activity level,and thus initially revealed tea tree control technology on adult trees vivo nutritional physiology.The results show that the simplified model of C.oleifera plants pruning vivo total soluble sugar,soluble starch,soluble protein content was the highest in all growth stages,sucrose synthase activity,the nitrate reductase activity is best.Control modes with various organic nutrients (total soluble sugar,soluble starch,soluble protein) content correlation analysis showed that the shoots growing and fruit development period,the regulation model and total soluble sugar content,soluble starch content was significantly correlated with changes(P0.05),but only in the soluble protein content of fruit development was significantly correlated,showing the tree control technology for sugar and other organic nutrients accumulation and utilization of greater impact.It is suggested that using a simplified model of the tree pruning restructuring on C.oleifera forest production.
