Lotus is an aquatic flower that steals roots. Lotus root is the underground big stem of lotus, which grows horizontally in the mud. There are many holes of different sizes in the cross section of lotus root, which is the air cavity formed by lotus to adapt to life in water. This kind of air cavity can also be seen in petioles and pedicels. There are also many small ducts for transporting water on the stem, and the walls of the ducts are attached with thickened mucilage lignocellulose.
It has a certain elasticity, and many white lotus roots appear when it is broken and stretched. Old lotus root has more silk than micro lotus root. The terminal bud of seed lotus root is called "lotus root", and it is covered with scales. After germination, white slender underground stems are drawn out, which is called "lotus root band". Lotus root band is segmented, and adventitious roots are surrounded by nodes. During festivals, leaves and flowers are drained.
The new lotus root formed at the top of the lotus root belt is called the main lotus root. The vigorous lotus root has 4-7 lotus root tubes, each with a length of10-25cm and a diameter of about 6-12cm. The branch of the main lotus root is called the secondary lotus root; The young onion that grows again from the sub-lotus root is called Sun Lotus Root, which is often only 1 node. The size, shape, color, morning and evening, depth of mud, quality and flavor of lotus root vary from variety to variety, and are also affected by cultivation and conditions.
The lotus leaf is large, with a diameter of 70 cm, and the whole line is shield-shaped, 14-2 1 radial veins. The leaves are dark green and rough, covered with short and blunt thorns. There is a layer of waxy white powder between thorns, so rain can condense into rolling water drops. The back of the leaves is green, smooth and hairless, the veins are raised, and there is a cylindrical petiole in the center to clean and jerk the lotus leaves.
There are dense spines on the stalk, the joint between the petiole and the underground stem is white, and the water and water are divided into green. There are three kinds of leaves: Mr. Ding Ya's leaves, small in shape and thin in handle, float on the water, called money leaves, or money leaves; The first leaves that grow from the lotus root are slightly larger and also float on the water, which is called floating leaves; Later, the leaves protruding from the lotus root were called vertical leaves.
Whether it is money leaves, floating leaves or vertical leaves, they are all relatively rolled into tendons before they come out. The size, height and sequence of vertical leaves show obvious ascending and descending steps with the growth time. When the new lotus root is formed, the pulled upright leaves are larger than the previous one and have shorter spines, which are called "back leaves". A small leaf with a short stem and reddish back appears in front of it, which is called "terminal leaf". As long as people can identify the terminal leaves, they can find the location of new lotus roots in the mud.
