| 摘 要： | 对不同年龄（15，29，42年）红松人工林结实品质的13项指标研究表明，林龄对人工红松林的结实品质有影响，林龄越大，球果产量越高；采果时间对红松人工林结实品质无显著影响，只是含水率变化较大，合理采果时间应在9月下旬；处于结实初期的林分，结果数量对红松人工林结实品质无显著影响。

| Abstract: | indexes of seeding quality have been studied on Pinus koraiensis plantation that were in different age (15,29,42 years). The results showed that the age of forest have effect on seeding quality of Pinus koraiensis plantation, the bigger the forest age is, the higher the yield is. The time of fruit picking have no distinct effect on seeding quality of Pinus koraiensis plantation, only the water ratio have some change, the rational fruit picking time is in the last ten day of September. To the forest that was in early days of seeding,the number of seeding have no distinct effect on seeding quality of Pinus koraiensis plantation. |
