【摘要】 对班克松引种与不同苗龄型、立地类型和坡位造林试验研究表明,引种班克松10年可结实育苗,千粒重达3.65g,生产种子32～40kg/hm²,生长量超过樟子松树高、胸径和材积分别为44.64%、13.8%和84.79%。造林用S_1-1苗最佳,4年生高生长可达2m。班克松未发生任何病虫鼠害和冻害,适应小兴安岭生态环境条件。更多还原

【Abstract】 A study on the introduction of Pinus banksiana and afforestation experiment with different age seedlings,site type and slope was conducted in this paper.The results showed that Pinus bangsiana of indroduction at ten years could beare seeds and grow seedlings.The thousand seed weight was 3.65g, the out put of seed was 32～40kg/hm².The growth was superior Pirus sylvestris vat.mongolica,and the tree height,dbh and volume of its indroduction at ten years were 44.64%,13.8%,and 84.79%. Seedlings of S_1-1 were the best to afforestation,increment of height at 4 years old was 2m.Pinus banksiana never have been affected by any disease,insect,rodent damage and freezing injury.It has adopted to the condition of ecological environment in Xiaoxing’anling.更多还原
