Abstract


In order to explore the best growth rate for the monocultured forest of Betula alnoides, the fertilization experiment was carried out in Wanshiqing area of Hua an Jinshan National Forest Farm. The experimental results showed that 250 g Calcium Superphosphate was optimal to use as basal fertilizer for B. alnoides reafforestation, and urea along with Potassium Chloride were used as topdressing, namely 50 g urea and 30 g Potassium Chloride were used as topdressing for first time of the first year, and for the second time, 100 g urea and 60 g Potassium Chloride were applied. In the second year, 100 g urea and 60 g Potassium Chloride were used as top dressing for the first time, and 150 g urea and 90 g Potassium Chloride were used for the second time. In the third year, 0 g urea and 90 g Potassium Chloride were used as topdressing for the first time, and 0 g urea and 0 g Potassium Chloride were used for the second time. 38 months after reafforestation, the average height, DBH and individual volume reached 6.76 m, 10.02 cm and 25.63 dm3, respectively.
