摘  要:
从南京林业大学引进895杨、95杨、797杨3个美洲黑杨杂种无性系,在甘肃天水渭河谷地苗期试验的基础上,于当地不同地区建立试验林,进行区域化对比试验。3a试验结果表明:3个无性系生长表现较好,其中以895杨和797杨优势明显,与对照加拿大杨差异极显著,其单株材积平均生长量均超过对照20%~60%,而95杨与对照加拿大杨无显著差异。初步认为,3个无性系可在甘肃省天水地区各杨树栽培区推广应用。

摘  要:
On the basis of seedling experiment on cutting propagation of three clones of Populus deltoides introduced from Nanjing Forestry University at Weihe valley in Tianshui of Gansu Province,northwest China,the regional forestation contrast testing in different local areas was proceeded by selecting No.895,No.95and No.797with obvious advantages.The threeyear testing indicated that the three clones were growing better,especially No.895and No.797.Compared with Canada poplar(CK),there was a very notable difference,with 20%~60% more than CK at the average volume growth per plant of No.895and No.797except for No.95.The final conclusion is that this three clones are supposed to be adaptable to the afforestation over the cultivation area in Tianshui of Gansu Province.
