Objective] Changes of seeding height , ground diameter, biomass, leaf area and chlorophyll content in different proportions of fertilizers were investigated to find out the optimum fertilization scheme .[Method] Through orthogonal experimental design , experiments of N , P, K fertilization were carried out in container seedlings of Zenia insignis.[Result and conclusion] Fertilization could promote the growth of seedlings and different nutrient elements , and their ratios had a different influence on the growth of seed-lings.The treatment of N4 P4 K2 and N3 P4 K3 played a greater role in promoting the growth of seedling height and ground diameter .Compared with the control group , it increased by 251.99%and 214.75%, respectively .Total biomass reached the maximum in the treatment of N 2 P4 K1 , increasing 298.03%com-pared with the control group .N is the biggest influence on the growth of Z.insignis seedling , followed by P.Reasonable ratio of N and P, which can effectively improve the quality of Z.insignis seedlings.
