摘　　要：大叶芳樟是黄樟的一个生理化学类型，由于座果率低，再加上成熟不一，鸟喜食，因此很难采摘到果实，继而繁殖实生苗木受到限制。为繁殖大叶芳樟苗木，保持其优良的遗传性状，发展大叶芳樟原料林，吉安市林业科学研究所科研人员于2011年8月及2012年5月采用3年生幼树萌芽条和17年生采穗圃萌芽条分不同季节、插壤选用枝条不同部位、不同留叶量在大田进行扦插，繁殖大叶芳樟。结果表明：以湿度80%以上，温度25℃~35℃，1年生萌芽条中、下部做穗条，留1/2片叶，用100mg/kg吲哚丁酸处理18h，其成活率均可达65%以上，最高达76.67%。Cinnamomum porrectum （Roxb.） Kosterm is a physiological chemistry type, because low fruit, coupled with varying maturity, eat by birds, so it is difficult to pick the fruit, then breeding seedling nursery stock was limited. In order to breed the seedlings of C. porrectum, keep its excellent genetic traits and develop its raw material forests, the researchers of Ji＇an City Forestry Research Institute made an field-cutting propagation experiment with three-year-old saplings sprout bars and 17 scion was born in the bud of points at Aug. 2011 and May. 2012, in different seasons, different parts of branches and different amount of left leaf on field. The result indicated that using the leaf of one-year-old sprout and leaving half-leaf, humidity 80%, temperature 25 ℃~ 35 ℃, treatment with 100 mg/kg IBA 18 h, the survival rate were 65%, the highest can up to 76.67%.
