为了给早熟高产多抗冬小麦新品种晋麦74号的推广应用提供配套的高产栽培技术,对其生育特性进行了初步研究,并与对照品种进行了比较。结果表明,早熟高产品种前中期生育快,分蘖早而强,成穗率高形成较多的亩穗数。穗分化开始早,进程快,抽穗早形成早熟的特点。中后期幼穗发育与籽粒灌浆均较快,其灌浆期长短与对照品种相同,但因抽穗早,成熟也早,能避开干热风,粒重高而稳定。该品种又具有多穗性强的特性,使其具备了播种期范围广和适应性强的栽培特点。
In order to provide high-yielding cultivation techniques for the popularization and application of early maturing high-yield and multi-resistance winter wheat new variety Jinmai 74, the fertility characteristics were studied preliminarily and compared with the control varieties. The results showed that the early middle and high yielding varieties of early maturing fertility, early and strong tillering, spike rate of formation of more acres per mu. Spike differentiation begins early, the process is fast, heading early to form a precocious trait. Mid and late panicle development and grain filling were faster, the filling period of the same length and the same as the control species, but due to early heading, maturity early, to avoid dry hot air, grain weight high and stable. The variety has the characteristics of more spike, making it has a wide range of planting and adaptability cultivation characteristics.
