【摘要】 用常规的繁殖与栽培方法,将沉水樟在中亚热带的低丘红壤地区进行了繁殖栽培试验,其主要结果是:①芽苗移栽,特别是将芽苗移植到容器中有利于防止苗木的个体分化,提高成苗率和优质苗的比例;②首次在沉水樟分布的北缘地带的低丘红壤地区进行了沉水樟的引种栽培,并获得成功,16年生的沉水樟年平均胸径生长量为2.0cm,年平均高生长量为1.25m,其中最大的一株年平均胸径生长量达2.4cm,年平均高生长量达1.5m,比同地同生境的其他树种生长都快;③沉水樟的冠高比是相对较低的,而高径比中等偏低,说明沉水樟顶端优势明显,树干通直高大圆满。结论认为沉水樟既是优良的珍贵用材树种,也是优良的园林景观树种。更多还原

【Abstract】 By routine method of propagation and cultivation,experiment of propagation and cultivation for Cinnamomum micranthum were done at red soil of low hill in middle subtropical zone,The results showed:①By germinant seedling transplant,especially germinant seedling being transplant to vessel bag,seedling individual differentiation was avoided,and surviving rate and high quality seedling rate were increased.②Cinnamomum micranthum was successfully introduced to red soil of low hill situated at upstate margin of distributing area for Cinnamomum micranthum.Which its average year DHB and height growth were 2.0 cm and 1.25 m respectively for 16 old Cinnamomum micranthum.and grow faster than other trees of same place and same environment.③That ratio of tree crown diameter and height was lower correspondingly and ratio of height and DBH was lower also indicated that Cinnamomum micranthum be of obvious top dominance.Based on the above-mentioned results,the author discovered that Cinnamomum micranthum is not only excellent rare timber tree but also excellent ornamental tree.更多还原
