Experiments were conducted using Eucalyptus urograndis DH32-29 as the experimental research object,and different fer-tilization formulas were used for the cultivation of Eucalyptus tissue culture seedlings.The results showed that fertilization had a pro-moting effect on the growth of height,ground diameter,and root length of Eucalyptus tissue culture seedlings,and fertilization could effectively improve the survival rate of Eucalyptus tissue culture seedlings.The survival rate of Eucalyptus tissue culture seedlings fertilized ranged indicating a good survival rate.In addition,the results of orthogonal experimental analysis showed that the factors affecting the height of Eucalyptus tissue culture seedlings were in the order of N>P>K,and the factors affecting the ground diameter of Eucalyptus tissue culture seedlings were in the order of K>N>P.The factors affecting the root length of Eucalyptus tissue culture seedlings were in the order of P>N>K.
