摘　　要：[目的]研究猪粪沼渣与化肥配合施用对玉米生长和产量的影响。[方法]采用田间试验方法进行玉米施用化肥情况下沼渣的适宜用量研究,筛选出沼渣与化肥的最佳配比。[结果]试验处理以施用沼渣30～45t/hm2配合施用450～600kg/hm2复合肥增产效果明显,比对照增产6.67%～16.03%,达到显著水平。[结论]农田适量施用沼渣能够明显提高玉米产量,减少化肥的施用量。该研究为农田合理施用沼渣、提高作物产量提供了理论参考。[Objective] The aim was to discuss the effects of matching application of residue and fertilizer on maize growth and yield.[Method]Field experiment was carried out to analyze the best matching application of residue and fertilizer.[Result]The experiment results showed that it was the experimental treatment that increased maize yield obviously with applying residue of 30-45 t/hm2 and fertilizer of 450-600 kg/hm2,which more 6.67%-16.03% than the comparison,and reached a very significant level.[Conclusion]It could increase maize yield and the amount of chemical fertilizer with applying appropriate residue to farmland obviously,which provided a reference for applying residue reasonably and improving crop yield.
