摘　　要：以鲜食玉米为试验对象,共设6个施肥处理,分别为沼肥N替代20%化肥N(BM20)、沼肥N替代50%化肥N(BM50)、沼肥N替代80%化肥N(BM80)、沼肥N替代100%化肥N(BM100)、不施肥(CK)、全部施用化肥(BM0)。通过两年田间试验,研究土壤肥力、鲜食玉米养分(植株、子粒)和产量对不同沼肥配施化肥施用模式的响应。结果表明,土壤速效养分含量、有机质、全磷含量值均以BM50处理最高。2020年BM20处理子粒全磷和全氮含量累积最多;2021年BM50处理产量最高(10276 kg/hm^(2)),比CK处理增加15.73%。2021年各处理产量相比2020年均有不同程度的提升。产量线性加平台模型结果表明,玉米产量在BM20至BM50处理达到最高值。因此,鲜食玉米沼肥施用模式推荐设置为沼肥N替代50%化肥N(BM50)。In this paper,fresh corn was used as the test object,and six fertilization treatments were set up,which were biogas manure N replacing 20%chemical fertilizer N(BM20),biogas manure N replacing 50%chemical fertilizer N(BM50),biogas manure N replacing 80%chemical fertilizer N(BM80),biogas manure N replacing 100%chemical fertilizer N(BM100),no fertilizer(CK),and all chemical fertilizer(BM0).Through two years of field experi⁃ments,the response of soil fertility,nutrient(plant,grain)and yield of fresh corn to different biogas manure com⁃bined with chemical fertilizer application modes was studied and clarified.The results showed that,soil available nu⁃trients,highest organic matter content and total phosphorus content in the mature stage appeared in the BM50 treat⁃ment.In 2020,BM20 had the highest accumulation of total phosphorus and total nitrogen content in grains.In 2021,the yield of BM50 was the highest(10276 kg/ha).BM50 increased by 15.73%compared with CK.In 2021,the yield of each treatment increased to varying degrees compared with 2020.The results of the yield platform model showed that the yield reached the highest value in the BM20 to BM50 treatments.Therefore,the recommended application mode for fresh corn biogas manure is BM50.
