| 摘 要： | 在辽宁省昌图县前双井镇以引进的6个无性系新品种杨树为材料，用乡土杨富杂Ⅱ号为对照作栽培比较试验，观察其生长量，抗寒性，感病性，感虫性等指标，用评分法评价各种综合表现的优劣。结果表明，N－119杨各项指标明显地超过对照，并优于其它品种，可扩大栽培，赛路杨生长量明显地超过本地乡土杨，且感病性，抗寒性等方面等于或接近对照，有一定的引种价值。

| Abstract: | Six new poplar clones were introduced in Qianshuanging township of Changtu county, Liaoning Province as experiment materials, and their indeces in growth, cold resistance, disease infection, and insect infection were evaluated and compared to the locally grown Fuzha II poplar. According to the comparison of the 4 indices, the study found that N-119 poplar showed all the scores obviously better than those of CK and other poplars, and was recommended for the area. The growth of Zhonglin 95 was higher, and its disease and pest infection was equal or near to the CK. So, the poplar Zhonglin 95 is also worthy to be recommended. |
