Abstract: In order to improve the quality of agricultural land,promote crop growth,and promote sustainable agricultural development.Field experiments were conducted to investigate the effects of different proportions of liquid manure instead of chemical fertilizers on the growth and yield of maize.The results showed that increasing the application of liquid manure by 45-90 t·ha^-1 can reduce the amount of chemical fertilizer by25%-50% and increased the yield of maize by 2.76%-6.04%;The treatment of reducing 10% chemical fertilizer and 30 t·ha^-1 liquid manure resulted in the highest corn yield,reaching 11 278.51 kg·ha^-1, and a nitrogen fertilizer utilization rate of 32.57%.In summary,the combination of liquid manure and chemical fertilizers can increase soil moisture and temperature, as well as increase the biomass and yield of corn,making it a reasonable fertilization model for increasing yield and nutrient balance of spring maize in the northern part of Northeast China.
