摘要
为研究闽楠造林苗木年龄与造林效果的关系,以江西永新县七溪岭林场相同立地条件下,裸地栽植1年生闽楠轻基质容器苗和裸地栽植3年生闽楠容器苗为研究对象,通过对造林3 a、4 a后林木树高、直径、鲜物质总质量等因子的分析,研究2种培育模式的效果及其机理。结果发现,栽植3年生闽楠苗与栽植1年生苗具有显著差异。因此,3年生闽楠容器苗造林具有较大的生长优势和显著的培育效果,优势苗木直接影响闽楠的造林效果。
In order to study the relationship of afforestation effect sand seedling age of Phoebe bournei, taking the 1 year old matrix container seedlings and 3-year-old field container seedlings of Ph . bournei under same site conditions in Qixiling forest farm of Yongxin county, Jiangxi province as the research object, through the analysis of tree height, diameter, total mass of fresh material and other factors after afforestation 3 a, 4 a, results and its mechanism of two kinds of cultivation modes were researched. It was found that 3-year-old pla nted seedlings and 1 year planted seedlings of Ph . bournei have signifi cant differences. Thus, afforestation with 3-year-old container seedling of Ph . bournei has a large growth advantage and significant nurturing effect, the advantaged seedlings directly influenced the effect of Ph . bournei.
