Abstract:Periodical investigation and systematic study of Populus euramericana cv. Ⅰ-214 stand have been conducted for 7 years from planting stock to tree technical maturity according to orthogonal design. The main results show that the tree growth grown in poor soils can be promoted obviously by application of fertilizers. The greatest increment of timber volume in fertilized plots was 132% compared with control plots. The effects of various fertilizers are different, of which Nitrogenous fertilizer is outstanding.The best effect could be got by rational fertilization of nitrogenous, phosphatic and potassic fertilizers.
