红皮云杉37个家系选择研究

Study on Families Selection in 37 families of Picea koraiensis

对营造7年生(苗龄3年)的37个红皮云杉家系保存率和生长量进行了统计分析。结果表明,红皮云杉家系间树高、当年抽梢、地径、冠幅均有较大差异,通过综合比较,pkor08hlj007、pkor08hlj010、pkor08hlj012、pkor08hlj032、pkor08hlj035较适宜在宜昌地区引种栽培。本研究结果造林后4年生树木生长量与国家云杉良种基地甘肃省小陇山林业实验局林业科学研究所育苗的3年生苗木生长量结果相吻合。

The paper statistical analyzed the survival rate and growth of 37 families of 7 years（3 years age of seedling） Picea koraiensis. The results show that tree height, the growth of new shoots, ground diameter and crown has bigger difference between 37 families. By comparing the found, pkor08hlj007, pkor08hlj010, pkor08hlj012, pkor08hlj032, pkor08hlj035 are suitable cultivation in yichang. The tree growth of four years of afforestation in Yichang is equals 3 years of growth in Xioalongshan excellent seed base in Gansu.
