本项试验采用3种密度×3种整地规格×2种抚育方式的析因田间试验设计,建立多点试验林。从4年生试验林幼树生长量来看,可初步认为日本落叶松造林以株行距1.5m×2.0m,密度3330株·hm-2,整地穴径40cm为宜。2种抚育方式生长量相似
This experiment adopted three kinds of density × 3 types of soil preparation specifications × 2 kinds of tending ways of factoring field experiment design, the establishment of multi-point test forest. According to the growth of 4-year-old experimental tree saplings, it can be preliminarily considered that the plantation distance of Larix kaempferi is 1.5m × 2.0m, the density is 3330 plant · hm-2 and the site preparation is 40cm. The growth of 2 kinds of tending way is similar
