东北落叶松人工林,已进行扶育间伐。各地对抚育强度和保留密度等问题,进行了不少调查研究,提出了不少方案。为了从不同角度探讨这方面的问题,对落叶松人工林的营养面积进行研究,将是很必要的。营养面积问题,不单是落叶松的问题,也是整个森林经营中应研究的问题。某一树种在一定年令阶段需要多大营养面积,才能充分发挥林地生产力,促进林木速生丰产,又不至于发生激烈地自然稀疏,这是一个有待解决的问题。
Northeast larch plantations, has been nurtured thinning. Various places on the tending strength and retention density and other issues, conducted a lot of investigation and study, put forward a lot of programs. In order to explore this issue from different angles, it is necessary to study the nutrient area of larch plantation. The issue of nutrient area is not only the issue of larch, but also the issue that should be studied in the entire forest management. It is an issue that needs to be solved in order to give full play to the productivity of forestland and to promote the fast-growing and high-yielding of trees without the intense natural sparseness of a certain tree species in a certain period of time.
