摘　　要：为充分发挥腐熟粪肥类有机肥在平衡养分中的作用,提高化学肥料的施用效果,提升耕地质量,更好地就近就地消纳有机粪肥资源,本研究开展了小麦腐熟粪肥有机氮同效当量试验,设置无氮处理(PK)、无机氮处理(N_(1)PK)和等氮量腐熟粪肥100%氮替代(MN_(2)PK)3个处理,明确小麦腐熟粪肥的有机氮同效当量,及其对小麦产量及构成因素、品质、养分吸收利用率及土壤理化性质的影响。结果表明,与无机氮处理相比,腐熟粪肥处理的小麦产量及产量构成因素、氮肥利用率均呈降低的趋势,以鸡粪为主要原料的腐熟粪肥有机氮同效当量为0.89;与无机氮处理相比较,施用腐熟粪肥提高了小麦蛋白含量,增加了土壤有机质、有效磷、速效钾和pH等肥力指标。综合结果表明,腐熟粪肥类有机肥可以提升小麦品质,改善土壤理化性质,提升耕地质量。In order to give full play to the role of organic manure in nutrient balance,improve the application effect of chemical fertilizer,improve the quality of cultivated land,and better utilize organic manure resources nearby and locally,the organic nitrogen equivalent test of wheat decomposed manure was carried out.It was divided into three treatments:no nitrogen treatment(PK),inorganic nitrogen treatment(N_(1)PK)and 100%nitrogen replacement of equal nitrogen content decomposed manure(MN_(2)PK)to determine the organic nitrogen isopotency equivalent of wheat decomposed manure and its effects on wheat yield,composition factors,quality,nutrient uptake and utilization rate and soil quality.The results showed that compared with inorganic nitrogen treatment,wheat yield,yield components and nitrogen utilization rate of decomposed manure treatment had a decrease trend.The organic nitrogen equivalent of decomposed manure with chicken manure as the main raw material was 0.89.Compared with inorganic nitrogen treatment,the application of decomposed manure increased wheat protein content,soil organic matter,available phosphorus,available potassium and pH.The results showed that decomposed manure could improve wheat quality,soil physicochemical properties and cultivated land quality.
