Abstract:

Nutrition diagnosis is an important basis for forest tree management and scientific fertilization, and also the key technique to evaluate fertilizer efficiency and guide fertilization. This paper summarized the research progress of forest tree nutrition theory, and the research status and progress of nutrition diagnosis techniques at home and abroad. It emphatically analyzed the characteristics and constraints of nutrition diagnosis methods such as appearance diagnosis, field experiment, soil analysis, plant tissue analysis and plant nondestructive testing, to provide technical support for the scientific development of forest tree nutrient management. At last, the paper pointed out the problems in the development of forest tree nutrition diagnosis in China, and discussed the research direction and application prospect of forest tree nutrition theory and diagnosis techniques.

Key words: nutrition theory, nutrition diagnosis, nutrient management
