Abstract: A fertilization trial of masson pine plantation was established on the red earth developed from granite in Shaowu City of Fujian Province in 1992.Two years, investigation show:The effectiveness of fertilization is tangible in the first year of planting and last to the second year.The total growth of height(H),groundline diameter(GLD)and crown width(CW)of the treatment plots is 14%～26%,8%～19% and 7%～23% higher than that of the check(CK)plots,respectively.The growth response to three nutrients compound fertilizer(50 kg/hm2 of N,P2O5,K 2O)is the best of all,with the current annual increment of H as 0.288 m(1 a),0.780 m(2 a)promoted by 44%,31% over CK.Next are to NP,PK and P,the H was promoted by 21%～46%(1 a),8%～31%(2 a)contrasting that of CK,respectively.There was no obvious difference between various P level treatments.Compared the effects of using calcium magnesium phosphate as basal or top-dressing alone,only basal manure has significant response,there was no difference between P top-dressing and CK.There is no obvious response to N or K fertilizer.So P is the deficient nutrient in such site.The application amount of 25 kg/hm2 of P2O5 is enough for the soil.
