小麦从起身开始即进入中后期生长阶段,此阶段是形成小麦经济产量的关键时期,因此,在前期管理的基础上,中后期更应进一步加强管理,一切措施都必须围绕营造合理群体、争取穗大粒多、增加粒重进行。只有这样,才能实现高产。一、控上促下群体适中和群体偏大的麦田,即生产上的一类麦田和旺长麦田,这类麦田茎数已达到或超过要求,无需春蘖成穗。起身期采取中耕培土措施,可控制春蘖滋生,减少养分消耗,促根系下扎;对 Therefore, on the basis of the previous management, the management of wheat should be further strengthened in the middle and late stages. All measures must focus on creating a reasonable group and striving for a win-win situation Large grain, increase grain weight. Only in this way can we achieve high yield. First, the control on the promotion of groups of moderate and large groups of wheat fields, namely the production of a class of wheat fields and wheat fields, the number of such stalks has reached or exceeded the requirements of wheat, without the need for spring tillers into spikes. Taken during the cultivation measures to cultivate soil, can control the growth of spring tiller, reduce nutrient consumption, promote root system tie;
