The results showed that the growth process was divided into the seedlings stage , the fast-growing period and the cessation of growth period. The mass fraction fertilizer concentration of 0.2% with the ratio of nitrogen ,phosphorus and potassium (3: 2: 1) was the best ,and improved the quality of nursery stock. The media of 3 peat: 1 vermiculite was the best matrix formula.
