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.
Growth Indicators of Pinus resinosa Provenances Plantation in Maoershan Area
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.
