The embryonic axis.
The soybean and mung bean are dicotyledonous seeds, and the process of germination is that the radicle first develops into a root. As the young root grows, the embryonic axis gradually elongates, bringing the two cotyledons out of the ground, the cotyledons unfold, revealing the germ, which develops to form the stem and leaves, soybean sprouts and mung bean sprouts are edible parts of the white part connecting the embryonic root to the germ is the embryonic axis.
The process of seed germination is: firstly, the seed absorbs water and expands, the seed coat softens, the nutrients in the cotyledons are transferred to the radicle, germ, and embryonic axis, and then the radicle develops into a root, the embryonic axis elongates, and finally the embryonic bud develops into a stem and leaves.
Expanded:
The growth of bean sprouts must have sufficient water, can be supplied by regular water drenching water, drenching method there are two ways, one is to drench each time the amount of water should be more, should be the entire container of bean sprouts generally drenched, so that drenching down to the water and out of the water temperature is the same.
Another method can fill the entire container with water, and then let go of the water, so repeat two or three times can be. Drenching should be cultivated container above the cover to open, drenching can be light even after drenching to cover the cover in a timely manner to re-cover the dense. Drenching time is generally 4-5 hours once, no matter day, night must be uninterrupted.
Harvesting: to reach the emergence of true leaves should be harvested immediately, such as waiting for the roots to grow more fibrous roots is too old.
