试验于2011年10月—2012年6月在安徽省凤台县农技推广中心进行。选用半冬性济麦22和春性淮麦30两个不同类型小麦品种,稻茬麦栽培,每个品种设置三个施氮量,分别是N1:180kg/hm2、N2:225kg/hm2、N3:270kg/hm2,分别以H0:10:0、H1:9:1、H2:8:2、H3:7:3、H4:6:4、H5:5:5为氮肥基追比,在拔节期追施氮肥,研究其对小麦各生育期生理特性、最终产量和主要品质性状的影响。研究结果如下:1.氮肥对稻茬小麦品种生长发育的影响试验表明施氮

作为世界主要的三大粮食作物之一,小麦生产对全世界粮食有着至关重要的作用。1979年首次报道有关小麦光敏感型细胞质雄性不育的消息,从那之后,一系列的光温敏雄性不育系小麦相继被发现。337S是目前唯一的两极型光温敏雄性不育系。337s对日长要求不高,没有细胞质负效应,育性稳定,制种区域广,具有优良的综合农艺性状等特点。它的发现是对植物雄性不育现象的一个重要补充。传统的小麦育种一般需要经过6个以上的世代
