摘要
为选择适合本地栽培的杨树优良品种，１９８３年与南京中医药大学林研所合作，从黑龙江、吉林、辽宁、内蒙古、北京５省（市）引进３９个杨树优良品种，以本地主栽品种山海关杨作对照，进行杨树引种试验研究。经过１４ａ的造林观测和统计分析，选出了９个生长快、干形直、抗性强的杨树优良品种。其中Ｉ－４５／５１和德杂×北京１号的材积生长量分别为山海关杨的１６８％和１６６％，在河北省东北部平原区极具推广价值。
In order to breed the fine variety of poplar adapted to cultivation in this locality, the researchers together with that from the Forest Institute of the Chinese Forest Academy of Science introduced 39 fine varieties of poplar in 1983 from Heilongjiang, Jilin and Liaoning provinces,and the Inner Mongolia Autonomous Region and Beijing area. Through comparing with Shanhaiguan poplar planted widely in the locality and, studying introduction test and observing afforestation and statistical analysing for 14 years, 9 fine varieties of poplar that grow fast,have upright trunks and strong resistance were chosen. Among them, the timber growing increase of I-45/51 and Deza×Beijing 1 are 168% and 166% of that of Shanhaiguan poplar respectively, which are of great popularized value in the plain of northeast area in Hebei Province.
