Its promotion and development are fast becoming the fast-growing timber and landscaping tree species in several provinces south of the Huaihe River in China, especially in the middle and lower reaches of the Yangtze River. Clonal fir clonal selection and application of excellent clonal afforestation work, rapid asexual reproduction is a technical key. Through two years of research, we use electronic leaf cutting propagation nursery and so on
