This paper dealt with an experiment on container seedlings culture with nonwoven and light medium for Cupressus funebris, a precious timber tree species, through orthogonal design. The effects of container height, quantities of controlled release fertilizer and the medium proportion on seedling quality of Cupressus funebri were studied. The results showed that seedling height, ground diamater, divarication number and the ratio of seedling height to ground diameter of Cupressus funebri were significantly affected by the height of container and the quantities of controlled release fertilizer, and little influenced by the medium proportion. There were significant different influences on seedling growth among different treatment combinations. The treatment combination No.9 was the best one with averaged seedling height, ground diamater, divarication number and the ratio of seedling height to ground diameter of 21.75 cm, 0.271 cm, 10.7 branches and 80.29, respectively. The treatment combination of No.6, No.3 and No. 5 were relatively good treatment. The length of seedling container of nonwoven with diameter of 5 cm for Cupressus funebris, could be selected as 10—12 cm. The quantities of controlled release fertilizer of 3 kg·m-3 and the seedlings density of 215—220 plants·m-2 could be the optimal for nursing seedling with high quality. The costs of medium proportion on several container seedlings base of Zhejiang Province were compared and analyzed.
