摘　　要：为了探究育苗密度对松树生长特征的影响,对不同育苗密度下松树各项生长指标及各部位生物量进行了测定。结果显示,适度增加育苗密度能够促进松树的生长及根部、茎部、叶部和整株生物量的积累,显示出正向的生长效应,但过高的育苗密度可能会导致竞争压力过大,资源分配不均衡,从而影响树木的生长和稳定性。因此,在实际生产中,需要综合考虑树木的生长特性、环境条件和育苗成本等因素,选择最适宜的育苗密度,以达到松树最佳的生长效果。In order to investigate the effect of seedling density on the growth characteristics of Pinus,the growth indexes and biomass of each part of Pinus were measured under different seedling density.The results showed that a moderate increase in seedling density could promote the growth of Pinus and the accumulation of biomass in roots,stems,leaves and whole plants,showing a positive growth effect,but too high seedling density may lead to excessive competitive pressure and unbalanced resource distribution,thus affecting the growth and stability of Pinus.Therefore,in the actual production,it is necessary to consider the growth characteristics of Pinus,environmental conditions and seedling costs and other factors to choose the most appropriate seedling density to achieve the best growth effect of Pinus.
