Abstract: 【Objective】 Effects To study the effects of different chemical fertilizer reduction patterns on growth, yield and fertilizer utilization of winter wheat under drip irrigation were studied,in order to providewith the view of providing theoretical basis for chemical fertilizer reduction of winter wheat under drip irrigation and finding out,Conducted the best pattern to reduce fertilizer. 【Method】 The control was conventional farm household (N₂₄₀P₁₀₅K_37.5) and blank treatment (N₀P₀K₀),as the control, set up 4 fertilizer reduction treatments were set up to determine, the yield and composition, agronomic characters, dry matter and fertilizer use efficiency of winter wheat under drip irrigation were investigated. 【Result】 Compared with conventional farmers, there were significant differences in yield, grain per spike and 1,000-grain weight among the four treatments, the highest yield was 9,673.54 kg/hm² treated with T₃, 36.8% of increase production. The trend of dry matter accumulation under reduced fertilization was consistent with conventional farmers and blank control, and it increased rapidly in the jointing stage, reaching the maximum value in the mature stage; Compared with T₅, the dry matter transport before and after anthesis of T₃ treatment increased by 30.2% and 29.4%, respectively; There were no significant differences in dry matter transport volume, transport rate and grain contribution rate among other treatments. The four indexes of spikelet number, panicle length, plant height and grain weight per panicle of T₃ treatment were highest, which were 16.57, 6.69 cm, 84.87 cm and 2.13 g. The agricultural efficiency of N and P fertilizer increased from 1.6-20.19 kg/kg and 5.13-59.00 kg/kg, respectively, compared with control treatments. And the partial productivity increased from 2.25-45.53 kg/kg and from 5.13-116.91 kg/kg. 【Conclusion】 There was no significant effect on the yield of winter wheat under drip irrigation using fertilizer reduction, and the rational application of nitrogen and phosphorus fertilizer was beneficial to increase the yield. Comprehensive comparative analysis showed that T₃ model (N₂₄₀P_52.5 K_37.5) was more suitable in our area.
