当前,我县冬小麦已开始逐步进入返青期。冬小麦返青期是调节群体大小决定成穗高低的关键时期,也是促晩弱苗升级,控制旺苗徒长的重要时期。返青期管理中心任务是:促麦苗早发,稳长,巩固冬前分蘖,控制无效分蘖,促进根系发育,为提高成穗打基础。所以,必须从现阶段开始,认真落实各项丰产栽培技术,确保今年我县小麦丰产,现阶段主要以促为主,增加春季分蘖,提高分蘖成穗为返青期管理的主攻方向。1返青期管理措施
At present, my county winter wheat has begun to gradually enter the greenback period. Winter wheat turning green stage is to adjust the size of the population to determine the height of the critical period, but also to promote weak seedlings upgrade, control the growth of the world’s important period. Greening management center tasks are: to promote early maturing wheat seedlings, stable, consolidate tillering before winter, control of ineffective tillers, and promote root development, in order to improve the foundation into a spike. Therefore, we must earnestly implement various high-yield cultivation techniques at this stage so as to ensure the high yield of wheat in our county this year. At this stage, we will mainly promote the growth of tillers and increase the number of tillers to become the main directions for the management of the rejuvenation period. 1 return green management measures
