摘要：

为了探索培育云南松人工林的有效措施，选择3个立地、3个来源的良种、3种基质培育的苗木和3种造林密度配置，按正交原理和随机区组排列原则安排云南松的造林组合试验，研究各培育措施对云南松蓄积、单株材积、胸径、树高等生长量的影响。结果表明，云南松各生长量的大小主要取决于立地条件；其次，受良种来源的影响也较大，而各种生长量大小基本不受育苗基质的影响。此外，胸径生长还受造林密度配置的影响。因此，在云南松人工林培育中首先选好立地，其次用对良种，再次要设置合理密度。

Abstract:

In order to explore effective cultivation measures for Pinus yunnanesisn plantation, an combined experiments, with three sites, three good seed sources, three seedlings from different nursery soils and three planting densities of P. yunnanensis planting were carried out according to principles of orthogonally and randomized block arrangement to study the effects of different measures on the growth, including stand volume, volume per tree, diameter at breast height and tree height. The results indicated that the sizes of kinds of growth were mainly up to the sites and also affected by seed sources, but were not impacted by nursery soils. In addition, diameter at breast height was also affected by planting densities. Therefore, for better P. yunnanensis plantation cultivation, the first measure was to choose good site, the second was good seed, and the third was appropriate density.
