玉米从抽穗到成熟称为花粒期。即玉米生长后期。雄穗抽出后,此期茎叶生长逐渐减弱乃至停止,经过开花受精进入以形成籽粒产量为中心的生殖生长阶段。这个阶段对玉米粒多粒重影响很大。此期的田间管理措施是: 1、浇攻粒水。俗话说:“干花不灌,减产一半”,说明这时期遇旱灌水的重要性。这是因为抽穗开花是玉米需水最多的时期,也是增加粒重,实现高产的关键时
Corn from heading to maturity known as the pollen period. The late corn growth. After the tassel is taken out, the stem and leaf growth of this period gradually diminishes or even ceases, and after the flowering and fertilization enter into the reproductive growth stage with the grain yield as the center. This stage has a great impact on the grain weight of corn. This period of field management measures are: 1, pouring water attack granulation. As the saying goes: “Dried flowers are not irrigated, cut in half,” shows the importance of drought irrigation during this period. This is because heading and flowering are the period when corn needs the most water, and it is also the key to increase grain weight and achieve high yield
