【摘要】

：

本试验于2011-2012年在内蒙古巴彦淖尔市水利科学研究所曙光实验站进行。以河套灌区主要种植模式小麦套种玉米作为研究对象,在节水灌溉(小麦拔节+小麦抽穗+小麦灌浆+玉米灌浆期灌水4次)和常规充分灌溉(小麦分蘖+小麦拔节+玉米拔节+玉米大口+玉米抽雄+玉米灌浆期灌水6次)两种模式下,系统研究了灌水和施氮量对套种小麦和玉米植株形态特征、光合特性、干物质积累、水分和氮素利用效率、土壤硝态氮含量及产量性

黄淮海夏玉米籽粒脱水特征研究

机械粒收技术是玉米生产的发展方向,收获期籽粒含水率是影响收获质量的主要因素。我国玉米机械粒收还处于起步阶段,目前在西北和东北等春播玉米区推广应用面积较大,黄淮海夏播玉米区仅限于试验示范,降低收获期籽粒含水率是推动机械粒收技术发展的关键。本研究于2014-2016年在黄淮海不同区域进行累计34场机械粒收试验,主要调查收获期籽粒含水率以及机械收获的破碎率、杂质率、落粒率和落穗率;于2014、2015和
