1、生育特点小麦生育后期是指小麦从开花受精至成熟这段时期。这个时期的生育特点是,小麦开花以后,不再形成新的器官,生长中心由根、茎、叶、穗的生长转移到籽粒上,是小麦形成籽粒产量的关键时期。在这一阶段中,小麦茎叶和根系功能逐渐由盛而衰,如果管理措施不力,很容易造成贪青或早衰,影响籽粒灌浆和产量的形成。 1, characteristics of reproductive wheat Wheat later in life refers to the period from flowering and fertilization to maturity. The characteristic of fertility in this period is that after the flowering of wheat, no new organs are formed and the growth center is shifted from the growth of roots, stems, leaves and spikes to the grain, which is a crucial period for wheat to form grain. During this period, the function of stems, leaves and roots in wheat gradually declined from high to low, and if poor management practices, it could easily lead to greyish or premature aging, which will affect the grain filling and yield formation.
