How do soybeans spread their seeds?

Soybeans are commonly known as soybeans. It is one of the most important food crops in China, which has been cultivated for five thousand years. It is known in ancient times as the main producing area in Northeast China. It is a crop whose seeds are rich in plant protein. So, how do soybeans spread their seeds?

I. what do soybeans rely on to spread their seeds

Soybeans are spread by ejection and by animals. Ejection transmission method: the soybean fruit is a pod, and the cracking mode is bifid. When the soybean is ripe and dry and hard to a certain extent, the two pieces of the pod will suddenly explode and curl, relying on their own elasticity to eject the seed, so as to achieve the purpose of spreading the seed.

Some activities in which animals spread people and animals often intentionally or unintentionally help plants spread seeds.

II. Main classification

Soybeans generally refer to their seeds. According to the seed coat color and grain shape of soybean, it can be divided into five categories: yellow soybean, green soybean, black soybean, other soybean and feed bean.

1. Other soybeans: the seed coat is brown, brown, red and other single color soybeans.

2. Yellow soybean is the most widely planted variety of soybean. Yellow soybeans are most commonly used to make a variety of soybean products, brew soy sauce and extract protein. Bean dregs or ground coarse powder are also often used in livestock feed.

3. Green soybean is a kind of soybean with turquoise seed coat. According to the color of its cotyledons, it can be divided into green skin, green kernel soybean and green skin yellow kernel soybean. Green soybean is rich in unsaturated fatty acids and soybean phospholipids, rich in anti-cancer ingredients such as saponins, protease inhibitors, isoflavones, molybdenum and selenium, and rich in protein and fiber. It is also one of the main sources of vitamin A, vitamin C and vitamin K, and one of the main sources of vitamin B.

5. Black soybean is the black seed of legume soybean. Also known as green beans, black beans, etc., taste sweet and flat. Black soybeans have the characteristics of high protein and low calories, with black skin and yellow or green inside.
