| 摘 要： | 为探讨红松生长指标对结实量的影响,调查了草河口地区30～80年生5个林龄红松人工林优树个体结实量和胸径等生长指标,利用灰色关联度方法分析结实和生长因子之间的关系。结果表明,与个体结实量关联度较大的3个生长因子是树高、胸径和侧枝长。因此,除了个体结实量外,树高、胸径和侧枝长可作为红松结实型优树选择的重要依据。 |
| 关 键 词： | 红松人工林 优树 结实 生长因子 关联分析 |

| Abstract: | In order to discuss the effects of growth factors on cone yield, cone yield and growth factors (DBH, tree height, crown width, etc.) of individual plus tree in Pinus koraiensis plantations of 5 tree-ages from 30 to 80 years in Caohekou areas were investigated. Analysis of the relationships between growth factors and cone yield by using grey correlation methods was conducted. The results showed that 3 factors correlated with cone yield quantities were in the following order: tree height, DBH and length of la... |
