Through the comparison of nitrogen, phosphorus, potassium formulated fertilization test on major rice soil genus of Yongchuan in multiple locations, the results showed that formulated fertilization can stabilize and increase the rice yield obviously（＋ 10.01% ）. Rational fertilization on nutrient absorption of rice what can reduce the fertilizer loss, and promote soil potassium nutrient activation and absorption, improve fertilizer use efficiency （ N ＋ 10.19 % , P2 O5 ＋ 3.30 %, K2 O ＋ 16.84 % ）.
