Abstract: To study the effect of different container sizes on the seedling raising of Quecrus variabilis and growth condition after afforestation,we use single factor randomized block design completely.The results suggest that container size A has greater influence on the seedling raising of Quecrus variabilis and growth condition after afforestation.The specific indicators of A are as follows:height is 36 cm,diameter is 6.4 cm,volume is 983 cm3,the form is deep cone.The seedling growth is the best in container size A.The height and ground diameter of Quecrus variabilis in the container are 47.9cm and 4.23cm.The Quecrus variabilis has good performance after afforestation and its survival rate reaches 100%.After afforestation the height and ground diameter of Quecrus variabilis are 63.5cm and 6.64cm,and it performs well on photosynthetic characteristics.Therefore,treatment A is the best choice for seedling raising and afforestation of Quecrus variabilis,in other words,the increase of the container volume and the depth can improve the growth of seedlings.

Key words: Quecrus variabilis, container specification, container seedling
