摘  要:
对11个产地河北杨的苗期生长进行了研究。通过物候观察、扦插成活率、生长状况及抗性测定等多项指标的研究,结果表明,吴旗11号和西宁5号的种苗在生长量及抗性方面均优于其它产地种苗;皋兰2号种苗次之,但皋兰2号种苗对黑斑病和叶锈病的自然发病率又低于吴旗11号和西宁5号种苗。因此、在生产上应发展吴旗11号、西宁5号和皋兰2号产地的河北杨。

摘  要:
The growth of Populus hopeiensis seedlings from 11 provenances was studied by indices of phonological observation,survival rate of cuttings, growing state and resistivity. The results indicated that Wuqi No 11 and Xining No. 5 seedlings are superior in growth rate and drought resistance than seedlings from other provenances. Gaolan No. 2 seedlings showed slightly lower growth rate but lower natural incidence by black spot and leaf rust than that of Wuqi No n and Xining No 5 seedlings. It is advis. ed that Wuqi No. 11, Xining No 5 and Gaolan No. 2 seedlings should be developed in profitable production.
