摘要： 为了探讨玉米秸秆全量还田下氮磷钾肥运筹方式对小麦产量及构成因素的影响，以冬小麦‘皖麦52’为试验材料，在长期小麦-玉米连作试验地上对一年玉米秸秆全量还田下不同氮磷钾肥运筹方式进行了研究。结果表明，一年秸秆全量还田除对小麦千粒重影响显著外，对产量及其他构成影响均不显著，同时随施氮量的增加千粒重呈下降趋势，千粒重最高的处理是N24P12K12(41.5 g)；不同氮磷钾肥运筹方式对小麦产量影响极显著，产量最高的施氮水平为N30P12K12(8572.5 kg/hm2)，施磷水平为N36P18K12(9028.5 kg/hm2)，施钾水平为N36P12K12(8500.5 kg/hm2)，除钾肥运筹对穗数影响达显著水平外，对其他产量构成影响均达极显著水平；秸秆还田与施氮互作对小麦产量及其构成影响不显著，与施磷互作除对穗粒数影响达显著水平外，对产量及其他构成影响均达极显著水平；与施钾互作除对小麦产量及穗粒数影响达显著水平外，对其他构成影响均不显著。

Abstract: Under whole quantity of straw returning condition, this study was to research the appropriate balanced fertilization technology using the positioning experiments .The different fertilizers logistics have an effect on yield under the condition of wheat-corn continuous cropping and whole quantity of straw returning. The results indicated that different fertilizer treatments have extremely significant on wheat yields and other factors but ears of K Fertilizer. Straw returning of corn under one year have no significance on wheat yields and production factors but weight of 1000 grains, with the N fertilizer application increasing, the tread of the weight of 1000 grains descended. The high weight of 1000 grains was N24P12K12 with 41.5 g. Straw returning and N interactions have no effect on yields and other yields of factors. Straw returning and P interactions have a significant effect on wheat grain number, and have an extremely significant effect on wheat grain yields and other production factors. Straw returning and K interactions have significant effect on wheat grain number and grain number but other factors. The high yield of different fertilizers was N30P12K12, N36P18K12 and N36P12K12, with 8572.5 kg/hm2, 9028.5 kg/hm2 and 8500.5 kg/hm2.
