摘　　要：对栽植在四平市铁东区山地不同坡位的21年生小黑杨和欧黑青杨进行材积生长对比试验。结果表明:品种杨对水分的需要更重于对土壤养分的需要,其人工林抚育浇水重于施肥;品种杨通常适宜在平地和山坡下腹地栽培,而对于速生的欧黑青杨适于在平地和山坡中腹、下腹部位栽培。The volume growths of 21-year-old Populus simonii×P.nigra cv.Baicheng and Populus nigra×P.cathayana cultivated in mountain area in Tiedong District of Siping City were compared.The results showed that the water requirement of poplar varieties was more important than the soil nutrient requirement.Watering in tending poplar plantation was more important than fertilization.Poplar varieties were usually suitable for cultivation on flat land and lower part of the hillside.Populus nigra×P.cathayana was suitable for cultivation on flat land and middle and lower parts of the hillside.
