Experimental analysis of organic nitrogen equivalent in decomposed wheat manure
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(N1PK)and 100%nitrogen replacement of equal nitrogen content decomposed manure(MN2PK)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.
