为了掌握莜麦的生长发育规律,进行适当的田间管理,以达到高产,我们以永492莜麦作材料,系统地观察幼穗分化全过程及其与外部形态的关系。试验在呼和浩特本院进行,于4月10日播种,4月下旬出苗,6月中旬抽穗,7月18日前后成熟,生育期85天左右。观察方法:在莜麦2-3个叶片时开始,每隔一天取样观察一次,分别摄下植株外部形态,并在双筒解剖镜下解剖幼穗,观察所处分化期,同时采用显微照像,一直进行到抽穗前停止。通过观察,我们初步明
In order to grasp the law of growth and development of barley and to carry out appropriate field management in order to achieve high yield, we use Yong 492 as raw material to systematically observe the whole process of spike differentiation and its relationship with external morphology. The experiment was conducted in Hohhot Hospital, sowed on April 10, emerged in late April, heading in mid-June and matured around July 18, with a growth period of about 85 days. Observation method: When 2-3 leaves of oatmeal were started, samples were taken every other day to observe the external morphology of the plants. The young spikes were dissected under a binocular dissection microscope to observe the differentiation stage. Meanwhile, Like, until the stop before heading. By observing, we tentatively stated
