摘　　要：采用稻田套播与传统条播两种栽培方式系统比较的方法,研究不同氮肥运筹下稻田套播方式对中筋小麦扬麦10号籽粒产量和品质的调节效应。结果表明:稻田套播方式对中筋小麦籽粒产量和品质影响显著。与传统条播方式相比,在同一氮肥运筹下套播方式中筋小麦除籽粒总淀粉及其组分含量显著高于条播方式外,籽粒产量、蛋白质含量、蛋白质产量、磨粉品质和面粉品质以及淀粉糊化特性的主要指标低于传统条播,且差异显著。稻田套播方式不利于中筋小麦扬麦10号优质的形成,在江苏淮南地区中筋专用小麦采用稻田套播方式宜适当增加施氮量且追氮适度后移。Two planting types, interplant wheat in paddy （IP） and conventional drilling （CD） were adopted to study the effects of interplant wheat in paddy and nitrogen application on grain yield and quality of medium gluten wheat, Yangnmi 10. The results were as follows： planting types significantly influenced grain yield and quality of medium gluten wheat. With the same application of nitrogen, The type of IP, compared with CD, gets higher content of starch and starch components in grain and lower grain yield, the content of grain protein, grain protein yield and the main quality indexes including milling quality, flour quality and paste traits. The type of IP was unfavorable for the grain quality of medium gluten wheat. Increasing the amount of N application and the portion of topdressing N after elongation stage is appropriate for interplanting medium wheat in paddy in the Southern Region of Huaihe River.
