The results show that the seedlings of L. tulipifera do not adapt for staying in the transplanting plots which after lifted. The seedlings of L. tulipifera should be planted after lifted in good season. Compare with the growth of tree height, living clear height, breast diameter and volume of L. tulipifera which planted after lifted in good season, the growth of seedlings of l.. tulipifera which after staying in the transplanting plot is only 69.16%, 66.12%, 62.63% and 29.84%.
