| 摘要: |
| 用4种不同遮光措施对云南松苗木进行处理，研究光照强度对云南松苗木生长的影响。以70%的光照强度处理(T1)苗木生长量和生物量最大，其1 a生苗最高可达11.23 cm,地径可达6.28 mm，总生物量为3.56 g，根干质量为0.99 g，茎干质量为0.79 g；100%的全光照处理（T0）育苗效果次之，而30%的光照强度处理（T3）育苗效果最差。 |

| Abstract: |
| In this paper, 4 shading treatments were used in cultivation of Pinus yunnanensis seedlings. The height, ground diameter and biomass of the seedlings were measured. The results showed that, the increament and biomass of seedlings under the 70% exposure (T1) presented the best with 11.23 cm of the seedling height, 6.28 mm of ground diameter, 3.56 g of total biomass, 0.99 g of root weight and 0.79 g of stem weight. Those under the full exposure (T0) were the secondary, under the 30% exposure (T3) presented the worst. |
