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. 相似文献

Height and diameter increment and timber quality in Scots pine (Pinus sylvestris L.) planted as seedlings of different sizes were studied in two experiments. When compared 32–37 years after planting, seedlings that were smaller than neighbouring seedlings at the time of planting, had generally attained lower height and diameter, and had higher mortality compared to seedlings that were of equal size or larger than their neighbours. Tree size was strongly related to seedling size two years after planting. Trees originating from small seedlings had thinner annual rings and branches than trees originating from large seedlings. These characters are of importance for timber quality. It seems that the competitive ability of a tree is to a large extent established early in stand development. 相似文献
