英文摘要： Tree nutrient is the basis of its growth and development. The nutrient rapid, comprehensive and accurate measured is the premise and key to implement precise management. The nutrient test efficiency greatly limits to Traditional determination of nutrient detection method for operation cumbersome, long cycle, time-consuming and expensive equipment,and high cost price. Electrochemical analysis has been widely used in various fields with the high sensitivity, simple equipment, easy operation, good results reliability. The research aims to explore the conductance method in forest nutrient measuring theory and method. Camellia oleifera was Chose for this research object. The tree leaves nutrient dynamic and its conductivity characteristics were the mainly research projects. Its biological significance of the nutrient content and electrical characteristic relationships has been clarified. Using the method of mathematical modeling theory, and based on the characteristics of conductance differential nutrient calibration model have constructed, and then establish its nutrient rapid detection technology system. By measuring the real-time electrical conductivity of trees can be obtained and evaluate the tree body nutrient characteristics. The workload of nutrient detection has reduced effectively in the future work. So the
