Abstract: In view of the problems of low utilization rate and large discharge of livestock manure nutrient resources in the farming pastoral area of northeast China,the field experiment introduced the Danish liquid fertilization technology and set up five treatments,no nitrogen fertilizer （CK）;conventiona fertilizer （FP）;67.5 t·hm^-2liquid cattle manure （N0PKM）;40%nitrogen reduction combined with 67.5 t·hm^-2liquid cattle manure （N1PKM） and 20%nitrogen reduction combined with 67.5 t·hm^-2liquid cattle manure（N2PKM）,so as to explore the effects of reducing and topdressing nitrogen fertilizeron dry matter accumulation and nutrient absorption and translocation of cold maize after anthesis.The results showed that nitrogen reduction combined with liquid cattle manure could effectively promote dry matter and nutrient accumulation and translocation,increase crop yield,reduce soil phosphorus and potassium surplus,and improve nutrient use efficiency.Among them,N1PKM was the best.Compared with FP,the proportion of dry matter accumulation after anthesis increased by 3.50%;the average growth rate increased by 16.07%;the nutrient accumulation of N,P and K increased by 10.04%,14.03%and33.33%after anthesis,especially at the mature stage;the translocation rates of nitrogen and phosphorus increased by 20.90%and 59.73%,respectively;the contribution rate of nitrogen and phosphorus transport to grain increased by 10.15%and 42.97%,respectively;the yield of maize increased by 5.76%;compared with N0PKM,the surplus of phosphorus and potassium in soil decreased by 15.48%and 25.05%,respectively.Therefore,nitrogen reduction combined with liquid cattle manure was of great significance to make full use of fermented liquid manure resources,reduced fertilizer and increase yield of maize in cold regions.
