落叶松的造林密度,从营林工作来讲,虽是个老问题,但也有进一步探索的必要,因为它关系到营林工作多快好省、还是少慢差费的问题。一般来讲如果密度掌握适当,就能充分的利用地力,使林木生长得又多又快又好,同时也能恰当的使用造林费。现就小兴安岭带岭林区,河岸冲积土的撂荒地,所造的不同密度落叶松林分析研究如下(见下表和图)。 Larix afforestation density, from the forest management is concerned, although it is an old problem, but there is also the need for further exploration, because it is related to the work faster and better management of the province, or less the problem of difference. Generally speaking, if the density is properly controlled, we can make full use of the earth’s force to make the trees grow more and faster and better, at the same time, the afforestation fees can be properly used. Now Xiaoxing’anling Ridge forest area, alluvial bank alluvial land, made of different density larch forest analysis and research are as follows (see table and map below).
