Abstract:  Multi-sites field experiments were conducted to study the effects of formula fertilizers application on rice yield, nutrient accumulation, fertilizer efficiency and economic benefit under the current production condition. The results showed that compared with the traditional fertilization, the average yield of the treatment with formula fertilizer application could increased by 691 kg/hm2, in spite of increasing fertilizer inputs （N, P2O5, K2O increased by 48, 7.5, 30 kg/hm2, respectively）, with accumulation of N, P2O5, K2O increased by 17.3%, 15.1% and 14.4%, respectively. Moreover, the fertilizer contribution rate and agronomy efficiency were increased by 7.8 percentage points and 1.0 kg/kg, respectively, the average net income of the formula fertilization treatment enhanced by 1 257 yuan/hm2.

摘要： 通过多点田间试验，研究了当前生产条件下施用配方肥对水稻产量、养分积累、肥料利用率和经济效益的影响。结果表明，与习惯施肥相比，尽管配方施肥处理增加了肥料投入（N、P2O5、K2O分别增加48、7.5、30 kg/hm2），但平均增产691 kg/hm2，N、P2O5、K2O积累量分别增加17.3%、15.1%、14.4%，肥料贡献率和农学效率增加7.8个百分点和1.0 kg/kg，纯收入增加1 257元/hm2。
