摘要
1985年从辽宁省章古台引种2年生樟子松苗到秦皇岛地区.经1996年调查,13年生樟子松高生长3.02m、胸径4.17cm,与当地同龄油松高生长2.63m、胸径3.45cm相比,长势要好,并优于北京山地及内蒙古红花尔基等地,证明秦皇岛地区引种是成功的.利用樟子松、油松针叶饲养赤松毛虫幼虫,2年生针叶饲养成活率相差42.8%,证明樟子松对赤松毛虫的抗虫能力大于油松.对针叶成分分析的结果显示,樟子松和油松在精油萜烯、脂肪酸、酚酸含量等方面均有较大差异.
The introduction of Pinus sylvestris var. mongolica Litvin.from Zhanggutai, Liaoning province to Qinhuangdao, Hebei province is successful. The growth tendency of P. sylvestris var.mongolica Litvin.in Qinhuangdao is better than that in other introduction areas and better than local P. tabulaeformis with same age. The resistance ability to Dendrolimus spectabilis of P. sylvestris var.mongolica Litvin.is stronger than that of P. tabulaeformis. The survival rate of larvae raised by P. sylvestris var. mongolica Litvin. needles is lower than that raised by P. tabulaeformis. The chemical analysis of the needles demonstrates that there are a lot of differences in contents of oil terpene, fatty acid, phenolic acid etc. between P. sylvestris var. mongolica Litvin.and P. tabulaeformis leaves.
