| 摘 要： | 通过多点田间氮磷钾肥对比试验，对永川区主要水稻土属在配方施肥情况下稻谷产量及氮磷钾肥利用效率进行观测．结果表明：氮磷钾肥配比施用能显著促进水稻稳产增产（＋10．01％），对养分的吸收能最大限度减少肥料损失，并促进土体中营养元素的活化与吸收，提高肥料利用效率（N＋10．19％、P2O5＋3．30％、K2O＋16．84％）．

| Abstract: | 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 % ）. |
