The low limit of mean temperature for shooting is 15℃, the mean height of 1\|year\|old and 2\|years\|old seedlings is 8.12 cm and 16.10 cm respectively, mean basal diameter of 2\|years\|old seedling is 0.19 cm. Soft\|wood + 50 mg/kg ABT + sandy bed in spring and hard\|wood + 100 mg/kg NAA + sandy bed in autumn are the best treatments for cutting propagation, the survival rate of afforestation may reach 100%. Their mean height is 70.48 cm, basal diameter is 1.01 cm, and branch is 40~50 cm in second year for plantation.展开更多
