河南中部秋播的大蒜一生有六个生育时期——萌芽期,幼苗期,蒜苔和蒜瓣分化期,蒜苔伸长期、蒜瓣膨大期和休眠期,各个时期均有其生育特点和生长中心。大蒜的干鲜重增长呈双峰曲线。第一高峰在11月份,第二高峰在4月上旬;叶面积系数和根条数变化也是如此。蒜苔和蒜瓣在3月下旬分化形成,但初期生长缓慢,4月份蒜苔加速伸长,5月初采苔后蒜头急速膨大。本文对大蒜各器官的分化特点进行了论述。各个器官(叶、苔、根、蒜头)均有自己的发育特点,它们之间密切相关。
Garlic in autumn planting in central Henan had six growth stages in its life-germination, seedling stage, differentiation of garlic and garlic, elongation of garlic, expansion and dormancy of garlic, and its growth characteristics and growth centers in different periods. Garlic dry weight growth showed a bimodal curve. The first peak is in November and the second peak is in early April; as is the change in leaf area coefficient and root number. Succulents and garlic cloves formed in late March, but their initial growth was slow. In April, the garlic was accelerated and elongated. In May, the garlic grew rapidly after picking the moss. This article discusses the differentiation characteristics of various organs of garlic. Each organ (leaf, moss, root, garlic) has its own developmental characteristics, closely related between them.
