摘要：珍贵用材树种由于其木材品质出众而倍受人们的青睐,并且随着人们生活品质的提高,对珍贵用材的需求与日俱增。我国珍贵用材树种天然资源严重匮乏,主要依赖进口的珍贵木材价格以每年30%的速率增长,因此发展珍贵用材树种前景看好。
An experiment with factorial design was conducted to investigate the effects of substrate composition,container size,slow-release fertilizers and air-cutting root on growth of one-year old seedling of Ormosia hosiei,Taxus wallichiana var.mairei and Phoebe chekiangensis.T.wallichiana var.mairei and P.chekiangensis were sensitive to substrate composition,while O.hosiei was scarcely affected by substrate composition.T.wallichiana var.mairei was favorite and tolerant to slow-release fertilizers fertilizers,and the height and ground diameter were promoted by the increased amount of the fertilizers.Slow release fertilizers also were beneficial to O.hosiei and P.chekiangensis which showed the largest height and ground diameter when 2.0 kg·m^-3 and 2.5 kg·m^-3 slow-release fertilizers were applied,respectively.Height and ground diameter of T.wallichiana var.mairei,and ground diameter of O.hosiei were promoted with increasing container size.A 4.5 cm×10 cm container was found to be the optimal size for P.chekiangensis.Root air-pruning promoted growth of O.hosiei and T.wallichiana var.mairei,but not for P.chekiangensis.There were significant interactions between different factors,and the change in single factor might affect the relative performance of seedling growth.Based on the main effects and interaction effects,three optimal seedling cultivation schemes were selected for each of the three elite timber species.
