中文摘要	选取2005~2013年吉林省3414田间试验中的氮肥用量处理,研究施氮水平对玉米产量和氮肥利用效率的影响,明确不同生态区之间的差异。结果表明,不施氮条件下吉林省玉米的平均产量为7 596 kg/hm~2。氮肥施用显著提高玉米产量,以适宜施氮量(N3)处理表现最好,产量最高达9 967 kg/hm~2,较不施氮(N1)处理平均增产2 371 kg/hm~2。玉米的氮肥农学利用率和偏生产力均以适宜施氮量的1/2(N2)处理最高,随施氮量增加氮肥利用效率均逐渐降低。不同生态区显著影响玉米的增产效果和氮肥利用效率,吉林省中部半湿润平原区的产量水平最高,东部湿润山区次之,西部半干旱平原区最低。施氮增产量和农学利用率以东部地区显著高于中、西部地区,偏生产力以东部地区最高而西部地区最低。
英文摘要	The N fertilizer rate treatments in the3414maize field experiments that conducted in Jilin prov- ince during 2005-2013 were collected, aiming to evaluate the effects of N fertilizer rate on maize yield and N fertiliz- er use efficiencies in Jilin province, and compare the differences among various ecological zones. The results showed that the average grain yield in the current maize production of Jilin province was 7 596 kg/ha, when no N fer- tilizer was applied. N fertilizer application increased significantly maize yield, of which, N3 treatment obtained the highest grain yield of 9 967 kg/ha. The agronomic efficiency(AE) and partial factor productivity(PFP) of N fertilizer declined with increasing N fertilizer rate, and the highest values were both observed in N2 treatment. Besides of N fertilizer rate, maize yield responses and N fertilizer use efficiencies were also affected by ecological zone. Of which, the highest maize yield were observed in the Central semi-humid plain area(CSPA), followed by Eastern humid mountainous area(EHMA), and that in Western semi-arid plain area(WSPA) was relatively lower. The yield increase and AE of N fertilizer were significantly higher in EHMA than those in CSPA and WSPA, while PFP was the highest in EHMA and lowest in WSPA.
