The results have shown that the growing incrementfrom June to August accounts for 40%～50%of the whole growth of a year. Root system iswell developed with a strong main root.The stumps are vigorous in rejuvenation and theirshoots of 4 months are long enough to be inoculated with lac insects.The average height ofthe transplanted seedlings can be up to 240 cm within 3 years;canopy 180 cm×220 cm ap-proximately;branches 2～3;length of shoot 65 cm. The total length of the useful shoots ofa tree is about 290 cm.
