摘　　要：2014~2015年在辽宁省农业科学院大固本玉米综合试验示范基地进行了缓释肥料减量施用试验。结果表明:与对照相比,施用脲醛型缓释肥米产量提高玉9.75%,收益增加13.20%;不设追肥且底肥用量减少16.67%的情况下,施用高分子型缓释肥仍能保障玉米的正常产量,平均增产4.08%,收益增加6.72%。另外,施用缓释肥料还提高了玉米的穗长、穗粗、穗粒数及百粒重。The experiment was conducted to study the effect of different slow release fertilizer and fertilization methods on yield and production profit of corn on Da guben experiment base of Liaoning academy of agricultural sciences in Fu xin District in the year 2014 ～ 2015.The results showed that the yield increased by 9.75％ and the production profit enhance about 13.20％,used as urea-formaldehyde compound fertilizer.Without top dressing and the amount of basal fertilize lower 16.67％ using the polymer slow-release fertilizer,which increased yield 4.08％ and production profit 6.72％ than CK.In the meantime,applying slow-release fertilizer improved the corn spike length,spike diameter,spike grain number and grain weight.
