【摘要】 研究不同微灌溉施肥模式对冬小麦产量和效益的影响，可为冬小麦高效灌溉施肥提供理论依据。采用裂区试验设计，以微灌溉施肥模式（微喷灌施肥、滴灌施肥）为主区，氮磷施用量(N₀P₁₂₀、N₁₈₀P₀、N₁₂₀P₁₂₀、N₁₈₀P₁₂₀、N₂₄₀P₁₂₀、N₁₈₀P₆₀和N₁₈₀P₁₅₀)为副区，随机排列，重复3次，研究了不同灌溉施肥模式和氮磷肥料运筹对冬小麦产量和经济效益的影响。结果表明：相同施肥水平下，微喷灌溉施肥模式的小麦产量和经济效益均高于滴灌施肥模式，2 a指标平均值分别提高了8.24%和12.00%；相同灌溉施肥模式下，均以N₁₈₀P₁₂₀处理的产量和经济效益最高。但滴灌施肥模式较微喷灌施肥模式平均节水187.5 m³/hm²，节水率9.26%。微喷灌施肥模式的冬小麦增产增收效果较好，该模式下N施用量为180 kg/hm²、P₂O₅施用量为120 kg/hm²时产量达到最高，为9 405.04 kg/hm²。更多还原

【Abstract】 Studying the effects of different micro fertigation modes on yield and benefits for winter wheat could provide theoretical basis for efficient irrigation and fertilization.A split plot experiment was conducted with main factors that was micro sprinkler fertigation and drip fertigation,while subordinative factors were nitrogen and phosphorus application rates (N₀P₁₂₀,N₁₈₀P₀,N₁₂₀P₁₂₀,N₁₈₀P₁₂₀,N₂₄₀P₁₂₀,N₁₈₀P₆₀and N₁₈₀P₁₅₀).The effects of different fertigation modes and nitrogen and phosphorus fertilizer rates on yield and economic benefits for winter wheat were studied.The results showed that under the same fertilization level,the yield and economic benefits of winter wheat from micro sprinkler fertigation mode were higher than those from the drip fertigation mode,and the 2 a average increased by 8.24%and 12.00%respectively.Under the same fertigation mode,N₁₈₀P₁₂₀treatment had the highest yield and economic benefits.However,the drip fertigation model saved an average of 187.5 m³/hm²of water and a water saving rate of 9.26%compared to the micro sprinkler fertigation mode.The micro sprinkler fertigation mode had a good effect on increasing yield and income of winter wheat.Under this mode,when the N application rate was 180 kg/hm²and the P₂O₅rate was 120 kg/hm²,the yield reached the highest at 9 405.04 kg/hm²level.更多还原
