摘要
本文以日本落叶松半同胞家系试验林为对象,通过对造林1年后的保存率和生长量调查分析,比较不同家系的早期表现。试验林平均保存率为98.4%,平均地径、平均树高生长量分别为8.06 mm、59.1 cm。结果表明:试验林保存率、生长量均差异显著,来自种子园的半同胞家系生长量优于来自母树林和人工林选择优树的半同胞家系,其中11,16,18,25号家系表现较好。
The preservation rate and growth of the half-sib family test forest after one year of Larix kaempferi was investigated and analyzed in this paper,the early performance of different families was compared. The average preservation rate of test forest was 98.4%, the average ground diameter and height increment were 8.06 mm,59.10 cm. The results showed that there were extremely significant differences on preservation rate and growth in different families. The half-sib families growth from seed orchard were superior to half--sib fam- ilies from seed stand and artificial forest. The best families were 11,16,18 and 25.
