小麦从抽穗到成熟称为生育后期,这是决定穗粒数和粒重的关键时期。正确指导小麦后期管理能有效地保证应有粒数,促进正常成熟和增加粒重,提高经济产量。特别是在今年一、二类麦田前期群体大,根系分布浅,田间郁蔽,光照不足,基部节间细长,抗倒能力下降,病虫草害发生较重的情况下,搞好后期管理就显得更为重要。
Wheat from heading to maturity known as the late growth period, which is to determine the grain number and grain weight critical period. Proper guidance of wheat late management can effectively ensure the number of grain should be, promote normal maturity and increase grain weight, increase economic output. Especially in this year’s first and second groups of early wheat crop groups, shallow root distribution, field Yuya, inadequate lighting, the base of the internodels slender, fell down ability, pest and disease occurred heavier cases, do a good job of late management It is even more important.
