为了验证配方肥在玉米上的应用效果，于2012—2013年通过定位试验，研究了施用配方肥对玉米干物质累积、产量和经济效益等方面的影响.结果表明：相对于普通复合肥，配方肥在玉米整个生育期养分供应更均衡，能够明显提高玉米大喇叭口期以后的干物质累积和养分累积，增加玉米穗粒数，并降低秃尖，玉米产量增加9.2%~18.2%，经济收益增加11.8%~27.0%.
為瞭驗證配方肥在玉米上的應用效果，于2012—2013年通過定位試驗，研究瞭施用配方肥對玉米榦物質纍積、產量和經濟效益等方麵的影響.結果錶明：相對于普通複閤肥，配方肥在玉米整箇生育期養分供應更均衡，能夠明顯提高玉米大喇叭口期以後的榦物質纍積和養分纍積，增加玉米穗粒數，併降低禿尖，玉米產量增加9.2%~18.2%，經濟收益增加11.8%~27.0%.

In order to understand the effect of formula fertilizer application on the dry matters accumulation ,yield and economic benefit of maize,field experiment was conducted from 2012 to 2013. The results showed that formula fertilizer supplied nutrient is more balanced than common compound fertilizer in the whole growth period of maize. It can obviously increase the dry matter and nutrient accumulation after the big trumpet period of the maize ,and increase the number of corn grain per spike but reduce the bald,increase the yield of 9.2%~18.2%,also it can increase the profit of 11.8%~27.0%.
