摘要

通过对2 a生可食松(Pinus edulis)苗木高、地径以及分枝数等生长参数的分析研究

并且应用聚类分析法对其苗高生长时期进行了划分。研究结果表明

可食松苗木高生长具较为明显的二次生长的特性

但高生长增量主要集中在第一次快速生长期(0411-0630)

生长增量为5.64 cm

占全年高生长增量的70.41%

是苗高生长的关键时期。地径生长也具有和高生长相近的特点

且地径生长表现出来和高生长相协调的特性。

Abstract

The growth parameters such as height growth

diameter growth and the divaricates of the 2-year-old nursery stocks of Pinus edulis were analyzed

and different growth stages to height growth are determined by sequence cluster analysis.The result showed that height growth of the Pinus edulis was evidently characterized by the twice rapid growth stages.However

the considerable 5.64 cm increment of height growth occurs in the first rapid growth stage(April 11-June 30)

and the increment at this stage accounts for 70.4% of the total increment in the whole year.It is the most important stage of fostering high quality nursery stocks of Pinus edulis.The diameter growth resembles and cooperates with the height growth.
