Abstract: 【Objective】 To study the effects of nitrogen management methods on dry matter accumulation and yield characteristics of spring wheat under drip irrigation in southern Xinjiang were studied and determine the suitable nitrogen application amount, time and proportion in the hope of providing basis for production practice. 【Method】Xinchun No. 6 and Ning 2038 were used as materials to carry out plot cultivation experiments. Four nitrogen application levels were set up in this study: N₀ (0 kg/hm²), N₁ (104.5 kg/hm²), N₂ (207.0 kg/hm²) and N₃ (310.5 kg/hm²), and for each level, four nitrogen application periods were set: R1 (100% base fertilizer), R₂ (60% base fertilizer + 40% jointing fertilizer), R3 40% base fertilizer + 40% jointing fertilizer + 20% booting fertilizer, and R₄ (20% base fertilizer +40% jointing fertilizer + 20% booting fertilizer + 20% booting fertilizer). 【Result】N₃R₄ treatment had the largest dry matter transport in pre-anthesis vegetative organs, dry matter transport rate in pre-anthesis vegetative organs and contribution rate to grains, N₃R₃ treatment had the largest dry matter accumulation after anthesis. The contribution rate of dry matter accumulation to grain after anthesis of Xinchun 6 was the largest in N₃R₄ treatment, and that in Ning 2038 was the largest in N₃R₃ treatment. When the amount of nitrogen was the same, the number of grains per panicle, 1,000-grain weight and yield of R₃ treatment were the largest; Under the condition of the same period of nitrogen application and the same proportion, the yield components and yield of N₃ treatment were the highest, but there was no significant difference between R₃ treatment and N₂ treatment.【Conclusion】When the nitrogen application rate was 310.5 kg/hm², and the proportion was base fertilizer: jointing fertilizer: booting fertilizer = 4∶4∶2 and base fertilizer: jointing fertilizer: booting fertilizer: filling fertilizer = 2∶4∶2∶2, both varieties could obtain higher yields, Xinchun No. 6 reached 1.21-1.26 g/plant (converted yield 8,511.78 － 8,930.72 kg/hm²), Ning 2038 reached 1.09－1.12 g/plant (converted yield 8,190.62-8,362.59 kg/hm²).
