Asparagus is the sprout of asparagus, also known as asparagus, southern asparagus, asparagus and so on. Its shape is similar to that of Reed, but it is completely different. It is wild, nutritious and unique. It integrates natural wild and green organic characteristics. The main producing areas are China, Peru, Germany, France, Spain, the United States, Japan and so on.

Asparagus is a whisker root system, which is composed of fleshy storage roots and fibrous absorbing roots. fleshy storage roots occur from underground rhizome nodes, most of which are distributed in the soil layer 30 cm from the surface. Asparagus has a long life and can extend forward every year as long as it does not damage the growth point. generally, it can reach about 2 meters, which plays the role of fixing plants and assimilating nutrients in stems and leaves. The fibrous absorption root has a short life span and will shrink at any time under adverse conditions such as high temperature, drought, soil salt or acid-base discomfort, too much water, lack of air and so on.
The stem of asparagus is divided into three parts: underground rhizome, scale bud and aboveground stem. Underground rhizome is a short abnormal stem, which grows horizontally. When the branches are dense, the new branches grow upward and make the root disk rise. The fleshy storage root is born on the rhizome, which has many nodes, and the buds on the nodes are covered by scales, so they are called scale buds. The apical scale buds of the rhizome accumulate to form a group of scale buds, and the scale buds germinate to form bulb product organs or aboveground plants. The aboveground stem is fleshy, and its tender stem is the product.
The leaves of asparagus are divided into true leaves and pseudo-leaves. The true leaf is a kind of degenerated leaf, which is born on the nodes of the aboveground stem and shows triangular film-like scales. The pseudo-leaf is an abnormal branch, fascicled, acicular. There are 4 axillary flowers every 1 year, green and yellow. Male perianth 5-6 mm long, Adnate to perianth segments below middle of filaments. Female flowers smaller, perianth ca. 3 mm. The berries are 7-8 mm in diameter, red when ripe and have 2-3 seeds. The flowering period is from May to June and the fruiting period is from September to October.
Asparagus is a dioecious plant, there are great differences between male and female plants in characters, and most of them are cultured in production. The male plant is short, has many branches, blossoms early, produces more stems, has a small single weight of young stems, but has a high yield and a long harvest life. The female plant is tall, the branches are sparse, the flowering is late, the stems are few, the young stems are thick, and the total yield is slightly lower.
Asparagus enjoys the laudatory name of the king of vegetables in the international market, which is rich in a variety of amino acids, proteins and vitamins, and its content is higher than that of ordinary fruits and vegetables, especially asparagine and trace elements selenium, molybdenum, chromium and manganese in asparagus. It can regulate body metabolism and improve body immunity.
