小麦一生可划分为三个时期:出苗至拔节为前期(苗期),拔节至抽穗为中期,抽穗至成熟为后期。前期生长良好的麦田,中后期要实行科学管理,才能实现高产;前期生长较差的麦田,只要针对存在问题,认真加强中后期管理,促进麦苗转化,仍能获得较好收成。 Wheat life can be divided into three periods: emergence to join the pre-stage (seedling stage), jointing to heading for the mid-term, heading to mature for the late. Early wheat well-growing, in the latter part of the implementation of scientific management, in order to achieve high yield; early growth of poor wheat fields, as long as the problem exists, and earnestly strengthen the mid-and late management, to promote wheat seedling transformation, still get better harvest.
