| 摘 要： | 本实验研究表明：截除马尾松高生长主梢和各级侧枝的主梢能有效地控制马尾松的树高生长和树冠增长,缩小树冠内膛空间,提高树冠有效采光面,从而可提高种子园采种母树密度;控制结实层上移,可有效降低种子园采种难度;增大采种母树结实层厚度,可提高采种母树的单株产量.

| Abstract: | By shaping and pruning the shoot of the main stem and the shoots of different classes of branches of the seed plant of Pinus massoniana, the tree height and canopy were limited, the canopy inner space was reduced and the sunlight absorption area increased. As a result, the density of available seeding plants increased, and the moving-up of seeding stratum was restricted. The thickened seeding stratum indicated a higher productivity. |
