摘要
黄金宝树(Melaleuca bracteata F.Muell.)是目前世界上较为流行的、视觉效果较好且较为珍贵的彩叶芳香乔木树种,为促进黄金宝树容器苗培育,采用杉木树皮、马尾松树皮、谷壳和草炭、田土为原料按不同体积比配制成4种复合基质,以常规育苗常用的田土作为对照进行育苗试验,结果表明,采用复合基质培育的黄金宝树容器苗,苗高、地径和冠幅生长均有了极显著的提高,其中采用杉木树皮50%+马尾松树皮10%+谷壳10%+草炭10%+田土10%为基质的处理组,黄金宝树容器苗平均苗高为179.72 cm、平均地径为2.79 cm、平均冠幅为132.86 cm,分别超过常规育苗44.54%、36.10%、38.70%;采用杉木树皮10%+马尾松树皮10%+谷壳10%+草炭50%+田土10%为基质培育的黄金宝树容器苗,平均苗高为180.70 cm、平均地径为2.93 cm、平均冠幅为131.39 m,分别超过常规育苗45.33%、42.93%、37.16%。复合基质的原料比例与黄金宝树的生长指标灰色关联度分析的结果显示,杉木树皮、草炭比例与黄金宝树生长指标关联度高于马尾松树皮、谷壳和田土,杉木树皮、草炭的比例与黄金宝树各生长指标也均呈正相关关系,且相关系数差异不大,说明杉木树皮经堆沤处理后,可替代草炭使用,在保障黄金宝树容器苗育苗质量的同时,以减少草炭资源的消耗和降低育苗成本。
Melaleuca bracteata F.Muell is currently the world's most popular,best visual and more precious new species of colorful aromatic arbor.In order to promote the cultivation of container seedlings of the Melaleuca bracteata F.Muell,fir bark and masson pine are used.Husks,grass charcoal,and field soil were used as raw materials to prepare 4 composite substrates in different volume ratios.The field soil commonly used in conventional seedling cultivation was used as a control for seedling cultivation experiments.The results showed that the container seedlings of the Melaleuca bracteata F.Muell cultivated by the composite substrate had a height,The ground diameter and crown growth have been greatly improved.Among them,the treatment group with 50%fir bark+10%masson pine bark+10%chaff+10%grass charcoal+10%field soil is used as the substrate,and the Melaleuca bracteata F.Muell container The average seedling height of the seedlings is 179.72 cm,the average ground diameter is 2.79 cm,and the average crown width is 132.86 cm,which are 44.54%,36.10%,and 38.70%higher than conventional seedlings respectively;using fir bark 10%+masson pine bark 10%+chaff 10%+peat 50%+field soil 10%are the container seedlings of the Melaleuca bracteata F.Muell cultivated by the substrate.The average seedling height is 180.70 cm,the average ground diameter is 2.93 cm,and the average crown width is 131.39 m,which respectively exceed the conventional seedling cultivation by 45.33%and 42.93%.,37.16%.The results of the grey correlation analysis between the ratio of raw materials of the composite substrate and the growth indicators of the Melaleuca bracteata F.Muell show that the correlation degree between the bark and peat ratio of the fir bark and the growth index of the Melaleuca bracteata F.Muell is higher than that of the masson pine bark,chaff and field soil,and fir bark and grass charcoal.There is also a positive correlation between the ratio of pyrophora and the growth indicators of the Melaleuca bracteata F.Muell,and the correlation coefficient
