Garlic is a string-shaped shallow root system without a main root. The main root group is distributed in the soil layer within 5-25cm, with a horizontal diameter of 30cm. In terms of plant morphology, the bulb itself develops from metamorphic branches, and its internodes are shortened into "bulb discs". The base and edges of the stem discs are rooted with roots on which the leaves and buds are primitive. After flower bud differentiation, the apical buds form flower stalks, and the lateral buds expand to form garlic cloves. The reproduction method of garlic is asexual reproduction, and the reproduction organ is a lateral bud on the mother's body, namely the scale bud. An adult garlic plant consists of roots, pseudostems, leaves, stalks, bulbs, etc.
The leaves of garlic include leaf body and leaf sheath. The leaf sheath is tubular and grows in a ring on the stem. The multi-layer leaf sheaths hug each other to form a pseudostem, which has the function of mechanical support and delivery of nutrients to the bulb.
