采用田间试验，研究了施用缓释肥料对夏玉米产量及经济效益影响。结果表明：施用缓释肥料能显著提高夏玉米的产量和经济效益。与常规施肥相比，施用缓释肥料可使夏玉米每667m2增产45kg，经济效益提高89元。进一步研究表明，缓释肥料促进玉米增产的主要原因是增加了玉米的穗长，从而提高了穗粒数。

Field experiment was conducted to investigate the effects of slow release fertilizer on the yield and economic benefits of summer maize. The results showed that the application of slow release fertilizer could significantly increase the yield of summer maize and economic benefits. Compared with conventional fertilization,the application of slow release fertilizer made the yield increase of 45kg per 667m2 and eco-nomic benefits increase of 89 yuan.Further studies showed that the main reason of slow release fertilizer for maize yield was increased by corn ear length,thus improved the number of ear grain.
