摘要
光皮桦是闽北地区常见的优良速生的乡土树种,具有较强的生态适应性。在不炼山的情况下进行光皮桦的造林试验证明,光皮桦作为迹地更新树种之一,在以红壤沙包土为主的立地条件上成活率较高,达到85%以上,4～10月(200天)平均高生长量在82.7 cm,与土层深厚、水肥条件较好的炼山造林地没有显著区别。
Betula luminifera was a common excellent fast-growing native tree species in northern Fujian which has strong ecological adaptability.Afforestation experiment of B.luminifera under the circumstances of non-burning showed that B.luminifera as one of slash regeneration tree species has high survival rate in site conditions of mainly red-sandbag soil,reaching more than 85%,the average height growth volume was up to 82.7 cm in 4~10 months（200 days）,and has no significant differences between the controlled burning afforestation sites with deep soil,better water and fertilizer conditions.
