Abstract: The research aimed to master the appropriate application amount of nitrogen and phosphorus fertilizer for maize and to provide theoretical basis and technical support for efficient use of nitrogen fertilizer and high yield of spring corn in eastern Jilin Province. Using field plot experiment, setting five nitrogen and phosphorus fertilizer levels, the influences of different levels of nitrogen and phosphorus combined fertilizationon spring maize yield and N absorption accumulation were studied. The results showed that under the condition of same application amount of K fertilizer (K2O 120 kg/hm2), appropriate nitrogen and phosphorus amount could significantly improve spring maize yield, and the influence effect was N>P. Along with the growth period, nitrogen accumulation of plant gradually increased, and reached the peak at mature period. When the amount of nitrogen and phosphorus was N 280 kg/hm2, P2O5 110 kg/hm2, the plant nitrogen accumulation reached the peak, which was 338.9 kg/hm2. Appropriate nitrogen and phosphorus interaction could improve the plant nitrogen absorption rate and the stage accumulation amount, maintain higher amount of accumulated nitrogen in later stage of growth period and obtain higher nitrogen utilization efficiency, nitrogen absorption efficiency and nitrogen partial productivity. Taking maize yield and N absorption and utilization efficiency into comprehensive consideration, under the condition of K2O 120 kg/hm2, applying N 280 kg/hm2, P2O5 110 kg/hm2 can obtain higher nitrogen absorption efficiency, also can make maize yield reach the peak of 12796.4 kg/hm2.
