关于红松更新方法问题,争论颇多。初期多数人认为,红松幼时偏阴,幼年阶段需要一定的庇荫,因此,育苗必须有庇荫,造林不能栽植在裸露地上,结论是必须实行择伐或渐伐作业和天然更新。当大量事实证明,叠光育苗、全光造林不仅能够成活,而且发育良好之后,又有人认为人工林叉干多、部位低,即使成林也不能成材;也有人说即使成材,由于人工林生长快,也得不到优质良材;也还有人说人工林投资太多,经济上不上算等等。总之,就是说红松不能人工更新,必须天然更新。 Debate on the Korean pine method of updating, a lot of controversy. In the early days, most people believed that when young Korean pine was young and in need of shade in early years, nursery plants must be sheltered and afforestation could not be planted on the bare ground. The conclusion was that selective cutting or gradual cutting and natural regeneration were necessary. When a large number of facts show that the stacked light nursery, all-light reforestation not only to survive, but also well-developed, some people think that the plantation fork more stems, low parts, even if the forest can not become a success; others said that even if the timber, because of plantation growth There are also people who say that there is too much investment in plantations and the economy is not on the list. In short, that is, pine can not be manually updated, we must update naturally.
