Abstract: Periodical investigation and systematic study on the fertilization to Eucalyptus urophylla stand were conducted for 9 years.5 fertilization methods (1.Nil,2.N100,3.P50,4.N100 P50,5.N100 P50 K50 )were adopted.The main results show that the tree growth can be promoted and the rotation time can be shortened by the application of fertilizer;a plenty of basal dressing can be available in the whole rotation(5～6 years);NPK is the best one in the fertilizer regimes used in fertilizer trials;the effects of various fertilizers are different,of which nitrogenous fertilizer is not effective, but phosphatic fertilizer is outstanding.
