通过10年6种密度造林试验研究结果表明,核桃楸和紫板的初植密度均以1.5m×1.5m为最佳。造林后10年其胸径、树高、蓄积量均高于其它密度;成活率、保存率高;自然整枝好,干冠结构合理。
The results of six density afforestation experiments at 10 years showed that the initial planting density of Juglans mandshurica and Violetplates was 1.5m × 1.5m. After 10 years of afforestation, its DBH, tree height and stock volume are higher than other densities; survival rate and preservation rate are high; natural pruning is good and the structure of dry crown is reasonable.
