由我院承担、武安市林业局协作进行的科研课题《太行山冀西南段中、低山区华北落叶松引种试验》,经过1982～1990年的工作,已经完成预定的研究计划,取得阶段性成果,并通过了河北省林业厅主持的专家鉴定。应邀参加鉴定的省内外专家一致认为,此项成果为太行山南段中、低山区增添了一个有希望、有价值的速生针叶树种;就幼龄期生长情况看,向低海拔、低纬度引种华北落叶松是个突破,居国内同类研究的先进水平。专家们建议继续观测已造华北落叶松林随年龄增长的生长表现,以确定其适宜培育的材种,并建议扩大中试和在适宜立地类型区进行推广。
According to the research project “Introducing Larix principis-rupprechtii” in the middle and low mountainous area in the southwestern part of Hebei Province in the Taihang Mountains undertaken by our institute and carried out by Wu’an Forestry Bureau, after the work of 1982-1990, the planned research project has been completed and the phased achievements have been achieved. And adopted by the Forestry Department of Hebei Province, presided over the identification of experts. Invited to participate in the appraisal of both inside and outside the experts agreed that this result for the southern section of Taihang Mountains in the low mountain added a promising and valuable conifer species; view of young growth, to low altitude, low latitude introduction of North China Larix is a breakthrough, ranking the domestic advanced level of similar research. Experts recommend continuing to observe the growth performance of Larix principis-rupprechtii Forests that have been made with age to determine the suitable species for cultivation and to expand the pilot plant and promote it in suitable site types.
