小麦越冬后,随着气温的回升,即进入返青期。小麦返青后生长发育加快,是决定成穗和形成籽粒的关键时期,也是春季麦田管理和进行农艺操作最方便时期。此阶段管理的好坏直接影响着小麦生长后期合理群体的构建,制约着穗大、粒多、高产、稳产的实现。因此,务必高度重视,因地制宜,分类指导,采取对应措施,促进苗情转化升级。近年来笔者在科研生产中探索出一套适合该时期不同类别麦田的促、控、防春季麦田管理技术。
After winter wheat, with the temperature rise, that is, into the greenback period. Wheat growth after rejuvenation to speed up, is to determine the formation of spike and the formation of grain key period, but also the spring wheat field management and the most convenient period for agronomic operations. The management of this stage has a direct impact on the construction of a reasonable population at the later stage of wheat growth, which restricts the realization of large ear, large grain, high yield and stable yield. Therefore, we must attach great importance to local conditions, classified guidance, take corresponding measures to promote the transformation and upgrading of Miao. In recent years, the author explored in the research and production of a set of suitable for the different types of wheat fields during the promotion, control, anti-spring wheat field management techniques.
