不同种源的红皮云杉在大兴安岭东坡的生长表现试验

GROWTH PHENOTYPE OF THE DIFFERENT SPECIES SOURCE PICEA KORAIENSIS IN GREATER XINGAN MOUNTAINS EASTWARDS HILLSIDE

】对红皮云杉按地理位置和气候条件进行种源划分是适宜的。根据红皮云杉的自然分布，可划为４个种源区：小兴安岭东南部种源区；大、小兴安岭交界种源区；完达山——老爷岭种源区；干旱草原种源区。各不同种源区内，红皮云杉的高、径生长存在显著的差异。大、小兴安岭交界区和小兴安岭东南部种源生长表现较好；干旱草原区种源生长表现最差。在整个大兴安岭东坡的红皮云杉造林，可根据具体情况选择最适宜的种源。

It is suitability that picea koraiensis divides species source by the geographical positions and climate condition. The species source can be divided to 4 regions on the basis of the natural distribution, as the Xiao Xingan Mountains southeast species source region;Greater Xingan Mountains is bounded on the Xiao Xingan Mountains species source region,Wanda Mountains and Laoye Mountains rouge species source region and the dry grasslands species source region.The height growrth and stem dgrowth have prominent difference in the different species region.The growth was better in Greater Xingan Mountains is bounded on the Xiao Xingan Mountains species source region and Xiao Xingan Mountains southeast species source rgcon.The growth is worst in the dry grasslands species source region.Afforestation in Greater Xingan Mountains eastwards hillside,maybe elected to suitest  picea koraiensis species source depending on the local condition.
