摘要：采用析因试验设计,开展了基质配比、缓释肥施用量和容器规格对1年生木荷轻基质容器苗生长和质量影响的研究。结果表明:随着泥炭比例的提高,木荷容器苗苗高和地径生长量增加,而根系参数减少致使根冠比下降;当每立方米基质中缓释肥量在2.5 kg以上时,缓释肥施用量对木荷容器苗地上部分生长和根冠比的影响较小,但随着施用量的增大却会明显影响根系的发育;容器规格对木荷容器苗生长和质量影响显著,容器规格的增大可明显促进苗高和地径的生长及根系的发育,但根冠比有所下降。从苗木质量和育苗成本等综合考虑,木荷轻基质容器苗的优化培育方案为:基质的泥炭与谷糠比为7∶3,每立方米基质中缓释肥施用量为2.5 kg,容器规格为5.5 cm×10 cm。此外统计分析还表明,木荷容器苗质量不仅受基质配比、缓释肥施用量和容器规格主效应的影响,而且其主效应间还存在一定的互作效应,即可根据基质配比相应地调整缓释肥施用量或改变容器规格大小,以达到低成本生产木荷优质容器苗的目标。
An experiment with factorial design was conducted to investigate the effects of substrate composition,slow release fertilizers,and container size on seedling growth and quality of Schima superba.The seedling height and ground diameter were promoted by high peat percent in substrate,whereas the root：shoot ratio（RSR） was reduced.The application of 2.5 kg·m-3 slow release fertilizers had little effect on the above-ground part of plants and the RSR.In contrast,the root growth was inhibited with the increased amount of slow release fertilizers.The plant height and ground diameter were promoted and the RSR decreased by larger container size.Based on the seedlings quality and cost,the optimal regime may be substrate composition with peat∶bran=7∶3,2.5 kg·m-3 of slow release fertilizers,combined with container of 5.5 cm×10 cm dimensions.The statistical analysis revealed that quality of container seedlings was affected by substrate composition,slow release fertilizers,as well as container size.The interactions were also found among the three main effects,thus it is possible to properly adjust the application of slow release fertilizers and container size according to the substrate composition so as to produce low cost and high quality container seedlings.
