冬小麦从抽穗到成熟是形成产量的关键时期。据报道,籽粒中积累的干物质有2/3来自生育后期的光合作用。为此,加强小麦生育后期的田间管理,确保小麦正常生长发育,减少籽粒退化,提高粒重,对夺取高产有十分重要的意义。
Winter wheat from heading to maturity is a key period of production. It is reported that 2/3 of the dry matter accumulated in the grain comes from photosynthesis in later growth period. To this end, to strengthen wheat field later in the field management, to ensure the normal growth and development of wheat, reduce grain degeneration and increase grain weight, to seize high yield is very important.
