AbstractTo promote thetechnologyof replacing chemical fertilizers withorganic fertilizersandstudyitspractical effcts in wheat production，an experiment was conductedat Yanghu Farm in Sixian，Anhui Province.The experiment included7fertilizationtreatments：nofertilization，conventionalfertilization，optimizedfertilization，organicand inorganic combined fertilization 1（organic fertilizer replacing 1 5 % chemical fertilizer）， organic and inorganic combined fertilization 2 （organic fertilizer replacing 30 % chemical fertilizer）， nitrogen substitution 1（organic fertilizer replacing （20號(hào) 1 5 % nitrogen fertilizer），and nitrogen substitution 2（organic fertilizer replacing 30 % nitrogen fertilizer）.Wheat yield， quality，economic benefits，and soil physicochemical properties were measured under diffrent treatments.The results showed thatboth organicandinorganiccombinationandnitrogensubstitution treatmentsincreased wheatyield; beneficialforincreasing the totalproteinand starch content of wheat grains and improving economic benefits; theuse of organic fertilizers insteadofchemical fertilizers hadapromoting effctonthe increase of availablephosphorus， available potassium，total nitrogen，total phosphorus，totalpotassium，andorganicmattercontentinsoil.Overall，the application effect of replacing 1 5 % nitrogen fertilizer with organic fertilizer（nitrogen substitution1） is better，resulting inhigher wheat yield and economic benefits.
