What kind of plant is asparagus? Where are its main producing areas
Asparagus is a food and also a plant. People generally do not grow asparagus at home, but they do eat it. Now, thanks to advanced technology, the producing areas of asparagus are no longer restricted, and everyone can buy fresh asparagus anytime and anywhere. However, to help everyone better understand asparagus, the editor has put together a fairly comprehensive set of information for everyone to refer to and learn from.
What kind of plant is asparagus
Asparagus generally grows from garden asparagus (Asparagus officinalis), which is most commonly seen in rural areas. It is the young shoot of garden asparagus, a perennial herbaceous plant in the Asparagaceae family, genus Asparagus, and can be eaten as a vegetable. The ones that have not emerged from the soil are white and are called white asparagus; after emerging, they turn green and are called green asparagus. Even if the production regions are different, no matter which asparagus variety it is, as long as it is exposed to sunlight it will turn into green asparagus, and if it is buried in soil or shaded from sunlight, the color of the asparagus will tend to be white, so asparagus needs a certain amount of light.
Where are asparagus producing areas
1. Asparagus was originally native to places such as the eastern coast of the Mediterranean and Asia Minor, and later gradually spread to Europe, the Asian continent, and the grassland and river valley zones of North Africa. It has a cultivation history of more than 2,000 years. It was introduced to the Americas in the 17th century, to Japan in the 18th century, and to China in the early 20th century. It is cultivated in countries all over the world, but the United States grows the most.
2. Asparagus cultivation in China can be said to have started in the Qing Dynasty, with a history of only more than 100 years. It was scattered in the suburbs of major cities in coastal areas and sold fresh locally. In the 1950s and 1960s, the export volume of asparagus from Taiwan, China increased year by year. By the 1980s, the vegetable export volume of Taiwan, China occupied a pivotal position in its total material export volume, and the export volume of asparagus was the largest.
When is asparagus on the market
1. The time asparagus is on the market generally varies according to various factors, such as climate, moisture, weather, and so on. In various parts of North China in our country, asparagus harvesting usually begins in early to mid-April. The duration of harvesting varies depending on conditions such as plant age, climate, soil quality, and fertilizer management, and may be earlier or later.
2. Sometimes asparagus harvesting needs to be judged according to the situation, whether it should be picked. When the number of emerging shoots decreases and they become thin and weak, harvesting must be stopped. If the harvest period is extended too much, the growth period of green stems and branches is shortened, the production and accumulation of nutrients are reduced, and the yield of tender stems the following year is affected. Generally, the harvest period in the first year is suitably 20 to 30 days, in the second year 30 to 40 days, and afterward it can be extended to about 60 days. For those who like to eat it, April is the best time to enjoy it.
After reading the above material, I wonder whether everyone has a better understanding of asparagus, and whether you want to go out right away and buy some asparagus to cook. In the future, when buying asparagus, you do not need to place too many requirements on the place of origin of the food. Generally, the place of origin of most foods is not very important.
