华山松种源选择研究

Researchon Provenance Selection forPinus armandi Franch

三峡地区通过对全国10省(区、市)35个华山松种源选择及中试研究,迄今已有26a,取得了结果,为在种子调拨范围和方向上发展华山松提供了科学依据。在三峡地区第1次取得了华山松种源选择的大量系统数据,确定了三峡地区适宜种源。最适宜三峡山区造林的是重庆城口的种子,比本省巴东种源材积提高60.1%,比平均值材积提高22.3%。

Selection and research on 35 Pinus armandi Franch.provenance and mid-test through 10 provinces（districts and cities）in the Three Gorges Region for 26 years have achieved result,and provided scientific basis in range and direction of allocating the seeds and developing the tree species.The suitable provenance of such tree species has been identified based on a large system data of the provenance selection obtained firstly in the Three Gorges Region.The most suitable species for afforestation in the region is the seed of Chongqing Chengkou,that raises 60.1% than provenance volume of Badong in Hubei Province,raises 22.3% than average value volume.
