摘要
引进优良的外来树种可以丰富本国或本地区林业建设的树种资源,增加木材产量和林产品的种类。通过对引进的美国东部7个脂松种源进行试验,得出更适宜栽植区的种源。在树高方面,较好的4个种源依次为MIDC(Dickenson County,Michigan)、MNCNF(Chippewa National Forest,Minnesota)、MIMC(Manistee County,Michigan)和WIOC(Oneida County,Wisconsin);2004年高生长较好的4个种源依次为WIOC、MIDC、MIMC和MNCNF;2005年高生长较好的4个种源依次为MIDC、MIMC、MNCNF和WIOC;地径较好的4个种源依次为MIDC、WIOC、MIMC、MNCNF。该4个种源间各项生长指标差异不显著;在保存率方面,7个种源间差异不明显。
The introduction of fine alien species can enrich the tree resources of forestry in the country or in the region,increase the wood production and the types of forest products.Experiments of introduced seven Pinus resinosa from eastern United States were conducted;the provenances which are more suitable to be planted in planting region were obtained.In the aspect of tree height,the four provenances are：Pinus resinosa ‘MIDC＇（Dickenson County,Michigan）,P.resinosa ‘MNCNF＇（Chippewa National Forest,Minnesota）,P.resinosa ‘MIMC＇（Manistee County,Michigan）and P.resinosa ‘WIOC＇（Oneida County,Wisconsin）.The four provenances with higher growth in 2004 are：P.resinosa ‘WIOC＇,P.resinosa ‘MIDC＇,P.resinosa ‘MIMC ＇and P.resinosa ‘MNCNF＇;The four provenances are：P.resinosa ‘MIDC＇,P.resinosa ‘MIMC＇,P.resinosa ‘MNCNF＇and P.resinosa ‘WIOC＇.The four provenances with optimal ground diameter are：P.resinosa ‘MIDC＇,P.resinosa ‘WIOC＇,P.resinosa‘MIMC＇,P.resinosa‘MNCNF＇.The difference among the four provenances is not significant.In the preservation rate,the difference among the seven provenances is not obvious.
