中文摘要	为优化陇中干旱、半干旱地区全膜双垄沟播玉米的氮肥运筹,提高玉米籽粒产量,通过大田试验,研究了不同氮素形态配比(NO_3~--N/NH_4~+-N)(N_1(1: 0)、N_2(1: 1)、N_3(1: 3)、N_4(3: 1)]对旱地全膜双垄沟播玉米耗水特性、产量和水分利用效率的影响.结果表明:不同氮素形态配比显著影响玉米0~ 200 cm土层的土壤贮水量,且N_4处理土壤贮水量最低.N_4处理农田总耗水量最高,较N_1、N_2、N_3分别显著增加了2.9%、1.9%、0.9%(2015)和2.3%、1.4%、2.2%(2017).玉米籽粒产量和水分利用效率(WUE)在3个生长季均表现为N_4处理最高,籽粒产量较其他处理分别高出3.3%~9.9%(2015)、3.5%~24.2%(2016)和8.3%~36.1%(2017),WUE则较其他处理分别高出1.6%~6.8%、4.9%~21.8%和6.6%~32.9%.N_4处理下玉米的氮肥偏生产力显著高于其他处理,然后依次为N_3、N_2和N_1.综合考虑,NO_3~--N/NH_4~+-N = 3: 1是适宜陇中干旱、半干旱地区全膜双垄沟播玉米增产的氮肥运筹措施.
英文摘要	To optimize the effects of nitrate (NO_3~--N) to ammonium (NH_4~+-N) ratios on water consumption characteristics, grain yield and water use efficiency (WUE) of maize under full film mulching on double ridges, a field experiment was conducted at semi-arid Loess Plateau of Gansu Province, China during 2015 to 2017 cropping seasons. The treatments with different ratios of NO_3~--N to NH_4~+-N included: N_1(1:0), N_2(1:1), N_3(1:3) and N_4(3:1). The results showed that different NO_3~--N/NH_4~+-N ratios had significant impacts on soil water storage in 0-200 cm soil layer. Treatment N_3 had the lowest soil water storage. Treatment N_4 significantly increased total water consumption by 2.9%, 1.9% and 0.9% in 2015, and 2.3%, 1.4%, and 2.2% in 2017,compared with N_1, N_2 and N_3 treatments, respectively. Compared with the other treatments, treatment N_4 increased grain yield by 3.3%-9.9%, 3.5%-24.2% and 8.3%-36.1% and improved WUE by 1.6%-6.8%, 4.9%-21.8%, and 6.6%-32.9% in 2015, 2016 and 2017, respectively. Treatment N_4 had the highest partial productivity of nitrogen fertilizer, followed by N_2,N_3 and N_1,respectively. We recommended treatment N_4 as the best nitrate and ammonium ratio to improve water use efficiency, N partial productivity, and grain yield of maize in arid and semi-arid Loess Plateau.
