Detailed Explanation of the Key Points of the Latest Asparagus Seedling Raising Techniques and Methods
Asparagus is a vegetable with very high nutritional value. Asparagus is rich in vitamin B, trace elements and various amino acids needed by the human body, etc. It is very helpful to human health. Therefore, many people are now growing asparagus on a large scale, but when growing asparagus, how to raise seedlings has become a task that many people need to do well. So today the editor has brought you the key points of asparagus seedling raising techniques. Let's take a look!
1. Choosing and preparing the land
The seedling bed for asparagus should be a loose, deep sandy soil rich in humus and with strong moisture-retaining capacity. In order to reduce the harm of diseases and insect pests, the previous crop in the soil must not be crops such as fruit or tomatoes. Then, in order to improve the growth ability of asparagus, after choosing the land, sufficient base fertilizer needs to be applied. The base fertilizer is mainly decomposed farmyard manure, supplemented by compound fertilizer, and it should be applied into the soil in layers and fully mixed with the soil. Then after about a week, apply compound fertilizer once more, finely level the broken soil, appropriately spray agents such as carbendazim for disinfection, and then make beds ready for planting.

Before sowing, we first need to soak the seeds in warm water at about 40 degrees for about 18 hours. Then prepare disinfected river sand and mix it together with the seeds. Place it in a cool and ventilated place for germination. When most of the seeds have sprouted and the soil temperature reaches above ten degrees, they can be sown. The sowing time is generally in spring every year, and the sowing amount should be controlled according to the planting area. The sowing method is mainly furrow sowing, with the depth of the sowing furrow kept at about 5 cm, and the plant and row spacing well controlled for sowing. After sowing, cover with fine soil, gently press the soil firm to increase the contact area between the seeds and the soil, then cover with soil and film, and water thoroughly.
3. Seedbed management
When the seeds break through the soil, uncover the film in time. When the seedlings grow to about 65 cm, start topdressing, about once a month, for about 3 times. Each time, mainly use urea. If the weather is relatively dry, then water appropriately. Of course, the water should not be too much. If there is too much water, drain it in time, and then do a good job of intertillage. Especially after rain, prevent the soil from hardening, which would affect the growth of asparagus. Then the most important thing is to do a good job in the prevention and control of diseases and insect pests to avoid some unnecessary losses.
4. Transplanting and field planting
First, sufficient base fertilizer should be applied in the field for field planting, mainly farmyard manure. Then in autumn, when asparagus enters the dormant period and the aboveground part gradually turns yellow and withers, carry out the transplanting work. When lifting seedlings for transplanting, pay attention to grading according to the number of roots of the seedlings. Those with more than twenty are grade one, and those with 10-20 are grade one, using the grading to determine their growth ability. When field planting, pay attention to the planting density. Generally, furrow transplanting is the main method. During transplanting, soil should be covered twice. After the first soil covering, gently press it firm to increase the contact area between the roots and the soil, and water once with diluted manure water. Then cover with soil again for about 5 cm to improve the soil's moisture-retaining capacity.
The above is a brief introduction to the key points of asparagus seedling raising techniques. The seedling raising work of asparagus is very important. It has a direct relationship with its yield, and thus indirectly affects the planting benefits. That is all for today's introduction. This article is for reference only.
