| Abstract: | In this paper,the field experimental of 3414fertilizer response to rice was introduced.It indicated extre-remarkable level in ternary quadratic equation,but significant level in N equation of single quadratic equation.The results showed that and the best economic application of fertilizer was obtained by ternary quadratic equation,which was N 147.90 kg/hm2,P2O5 127.95 kg/hm2,K2O 138.75 kg/hm2,and single quadratic equation of fertilizer effect was N 211.6 kg/hm2,P2O5 108 kg/hm2,K2O 136.4 kg/hm2. |
