在植物分类学上,大、元麦归大麦属,而小麦属于小麦属。大元麦的幼穗发育似小麦,但又有不同的地方。必须掌握它的幼穗发育规律,抓住栽培关键,才能夺取高产。大元麦的幼穗分化过程 1.生长锥初生期这时幼穗没有发育。用普通显微镜观察,茎顶端生长锥扁平。麦苗芽鞘长2厘米左右,第1叶露鞘(图1)。 In plant taxonomy, large, meta-wheat barley belongs to, and wheat is wheat genus. The ear of Dayunma grows like wheat, but there are different places. Must grasp its law of panicle development, grasp the key to cultivation, in order to seize high yield. Dahome Mai panicle differentiation process 1. Growth cone initial period when young panicles did not develop. Observed with a normal microscope, the top of the stem growth cone flat. Wheat sprout sheath length 2 cm, the first leaf dew sheath (Figure 1).
