Asparagus, also known as asparagus, is a seedling of asparagus, a perennial herb of Asparagaceae, which can be eaten by vegetables. Unearthed white bamboo shoots are called white bamboo shoots, and unearthed green bamboo shoots are called green bamboo shoots. The plant is as high as 1 m, the root is 2-3mm thick and the stem is smooth, so it has the title of "the king of vegetables".

The habit of asparagus

Asparagus has strong adaptability and is planted in many parts of the world, but the quality of asparagus planted in northern China is better than that in the south, mainly because the asparagus in the north grows for a long time, has less water content and tastes better than that in the south. Asparagus likes sandy weak acid soil with high organic matter content, which is cold-resistant and drought-tolerant, and likes light.

Asparagus shoots new stems 2 ~ 3 times or more every year. Generally, the tender stems sprouted in spring are used for food, and their growth depends on the nutrient supply stored in the roots the year before. The growth of tender stems and the formation of yield are positively related to the number of mature stems and the lush degree of branches and leaves in the previous year. With the growth of plant age, the number of tender stems and yield increased year by year.
