主要以红松结实为选择指标,在红松人工林中进行如何进行优树选择以及选择后对种子质量的影响进行了研究。通过分析结实与生长因子间的关系,结实与年度间的关系,确定了在红松优树选择时,采用3株大树法进行选择,红松结实与胸径、树高关系密切,丰年进行选择效果要好于欠年时的选择效果,结实高产优树经过初步选择后,应进行连续观测,以便于提高优树的选择效果。对于选择红松结实高产优树进行无性繁殖后,种子质量不会下降。
The main index of Korean pine is selected, how to choose superior tree in Pinus koraiensis plantation and the influence of seed quality after selection. By analyzing the relationship between seed setting and growth factors and the relationship between seed setting and annual, it was confirmed that when selecting the optimal tree species of Pinus koraiensis, three tree methods were used to select the tree species, The effect is better than that of the result of selection in the year of the year. After the initial selection of the sturdy and high-yielding excellent trees, the continuous observation should be conducted in order to improve the selection effect of the elite trees. Seed quality will not decline after selecting asexual seedlings of Pinus koraiensis.
