What Is The Breeding Method Of Asparagus

- Apr 18, 2018 -

The breeding method of asparagus is divided into two types: plant propagation and seed propagation.

Points in plant breeding

It was planted in the field by a plant of good fertility, dug out the root and divided the underground stem. Its advantage is that the characters of the plant are consistent and orderly, but the transportation is inconvenient when it is difficult to transport, and the growth is weak after planting, the yield is low and the life is short. It is usually bred for good breeding.

Seed breeding

It is easy to transport, has large propagation coefficient, strong growth, high yield and long life. This method is used for reproduction in production. Seed reproduction has the distinction of broadcasting and seedling.

Live cultivation

The plant growth potential is strong, the plant growth is growing quickly, the garden early, early production, the high yield of the first year. However, the seedling rate is low, the utilization of seed is large, the management of seedling stage is difficult, and it is easy to breed weeds. The land use is not economical, the cost is high, the root plant is shallow, the plant is easy to fall down, and the economic life is not long. Therefore, in addition to the land, the climate is warm, the asparagus growth period of the local adoption, usually not very useful. However, since the 1970s, due to the popularization of mulch technology and herbicide, the problem of low emergence rate and weed breeding has been solved, and the application has been gradually increased.

Seedling transplanting


It is the most commonly used method in production. It is easy to manage in the seedling stage, the seedling rate is high, and the planting quantity is small, which can shorten the breeding period of the root plant of da tian, which is conducive to improving the utilization rate of land.

(1) cultivation

The asparagus is divided into two kinds: seedling and seedling. If the seedling place and method are divided, the seedlings can be seeded live, seedling and seedling of the protected field, and so on.

The seedling age is 60 ~ 80 days, the seedling height is 30 ~ 40cm, the stem count 3 ~ 5. It is generally planted in the protected area during the cold season. After the final frost is planted in the field, it is beneficial to prolong the growing season of the year. This seedling is convenient to plant, save time, work, and do not harm the root, not easy to infect soil disease. After planting, the plant grows and develops rapidly, which can greatly shorten the cultivation period of the plant. It is generally planted in the Yangtze river basin and north China in 2 ~ 3 months, and planted in May, the next year can start harvesting. However, in the early years of planting, the field leaves are low and easy to be damaged by grass, and the plants are prone to fall down. Therefore, the management should pay attention to the prevention of weeds and the cultivation of soil.

Distribution range

China, Peru, Germany, France, Spain, USA, Japan.

At present, China is the largest producer of asparagus, with a total output of 6,960,357 tons in 2010, far ahead of other countries (second Peru 35,209 tons, third Germany 92,404 tons).

The relative concentration of asparagus in China is distributed in xuzhou, shandong and heze, shandong province. In addition, chongming island has distribution. The quality of asparagus grown in the dry field in the north is better than that of asparagus in the southern paddy field. There is little moisture in the dry field, the growth cycle of asparagus is slow, the water content of the stem is small, and the taste is good. The asparagus grown in the paddy field absorbs more moisture and grows faster.

Nutritional value

Asparagus is rich in vitamin B, vitamin A and folic acid, selenium, iron, manganese, zinc and other trace elements. Asparagus has various amino acids necessary for human body.

Asparagus contains more selenium than normal vegetables, is close to the mushroom with rich selenium, and can even compare with the selenium content of sea fish, sea shrimp and so on. All in all, from the white asparagus, green bamboo shoot amino acids and zinc, copper, iron, manganese, selenium element analysis results, except for white asparagus contains aspartic acid is higher than the green bamboo shoots, and other amino acids and the trace elements were higher than in white asparagus green bamboo shoots.
