【摘要】 1987年从加拿大引种小干松、白云杉、落基山北美黄杉等7个树种98个地理种源。用一地播种育苗、多点造林方法研究。结果表明:有8个小干松种源(占引种数22.2％),5个白云杉种源(占引种数100％)适合黑龙江东部林区造林绿化。并指出:在引种和种源选择中大陆度表达的气候型和最低温度值比经纬度更重要。更多还原

【Abstract】 It has been done that introduced the 7species and 98 geographic provenances of Pinus contorta var. latifolia, Picea glauca, and Pseudotsuga menziesii etc. from Canada in 1987. The method of seeding in one and forestation in different places was used for research. The results show that there are 8 provenances of Pinus contorta var. latifolia, (22.2% in total ), 5 provenances of Picea glauca, (100% in total) adapted in the forestation and greening in the east of Heilongjiang Province. And pointed out that the climatype and absolute minimum temperature conveyed by continent degree is more important than longitude and latitude.更多还原
