The field experiment was conducted to study the effects of nitrogen management on the dynamic changes of soil inorganic nitrogen，nitrogen uptake and translocation，yield and nitrogen use efficiency of summer maize in lime concretion black soil of the south of Huang-Huai-Hai region.The study aimed to provide scientific basis for rational fertilization of maize in this area，to increase production and efficiency，and to simplify production.The field experiment was conducted at the experimental station of Mengcheng Agricultural Scientific Institute，Anhui Province in 2018.The maize hybrid was Luyu9105 in this experiment.Six fertilization treatments were compared，including no nitrogen fertilizer(T1)，one-off application of convention nitrogen fertilizer(T2)，1∶1 split application of convention nitrogen fertilizer between base and topdressing at jointing stage(T3)，1∶1 split application of convention nitrogen fertilizer between base and topdressing at big flare stage(T4)，one-off application of convention and loss-control fertilizer(1∶1，T5)，one-off application of loss-control fertilizer with the amount of nitrogen input was 25% reduction.(T6) .N at a rate of 262.50 kg/hm² was used in T2～T5，and 195.00 kg/hm² in T6.The results showed that different nitrogen management significantly affected the grain yield and yield components，plant nitrogen uptake and accumulation，and nitrogen use efficiency.Topdressing of convention nitrogen increased NH4+-N and NO^3--N content at 0～40 cm layer soil from anthesis stage to maturing stage，and promoted nitrogen accumulation of maize，while decreased nitrogen translocation from vegetative organs to grain pre-anthesis than 100% basal fertilizer.T3 and T4 treatments increased maize yield，nitrogen use efficiency(NUE)，nitrogen uptake efficiency(NUPE)，agronomy efficiency(NAE)and partial factor productivity(NPFP)by 6.89%～11.11%，18.84%～24.48%，7.15%～9.29%，23.49%～37.88% and 6.89%～11.11%，respectively，compared to N2.NH4+-N and NO^3--N content at 0～40 cm layer soil in T5 treatment were significantly higher than that in T2 after anthesis stage，which could better match nitrogen supply with nitrogen requirement of maize growth.Thus，T5 treatment increased dry matter and nitrogen accumulation of maize after anthesis stage，and significantly decreased nitrogen translocation rate and contribution rate to grain pre-anthesis by 11.58% and 22.16%，respectively，compared to N2.Finally，Maize yield，NUE，NUPE，NAE and NPFP of T5 treatment were 9535.15 kg/hm²，36.01%，0.82 kg/kg，14.00 kg/kg，36.32 kg/kg，respectively，which were significantly increased by 15.00%，27.88%，10.59%，51.14% and 15.00% compared to N2.T5 treatment increased net income by 706.94～1302.08 yuan/hm² compared to T3 and T4 treatments.Loss-control nitrogen fertilizer decreased nitrogen by 25%，it did not affect the maize yield and economic.benefit.，but could improve NUE，NUPE，NAE and NPFP by 41.96%，37.41%，38.44% and 35.74%，respectively，compared to N2.In this way，reduced fertilization of loss-control fertilizer could enhance nitrogen efficiency and reduce environment pollution.In conclusion，the combination of convention and loss-control nitrogen fertilizer(1∶1)could not only increase maize grain yield，economic and nitrogen efficiency，but also realize maize simplified production techniques of one-off application in lime concretion black soil of the south of Huang-Huai-Hai region.
