How to plant asparagus in spring? These planting techniques are essential to master

Asparagus is the young shoot of Asparagus officinalis, a perennial herbaceous plant of the genus Asparagus in the family Asparagaceae. It is often eaten as a vegetable and has very high nutritional value. The shoots that have not emerged from the soil are white and are called white asparagus; after emerging they turn green and are called green asparagus. Below is an introduction to the “King of Vegetables” asparagus spring planting techniques.

1. Raise seedlings at the right time

The common planting method for asparagus is sowing and raising seedlings, which can effectively increase the germination rate of asparagus, improve seedling quality, advance the time to maturity, and expand the utilization rate of the land.

When using the sowing and seedling-raising method, choose fertile, loose sandy soil for the seedling bed. The soil layer does not need to be too thick; keeping it at about 20cm is sufficient. Before sowing, apply sufficient base fertilizer, mainly decomposed poultry manure and mainly phosphorus fertilizer. Since spring temperatures have not fully risen yet, the seedling bed temperature must be controlled after sowing and kept at around 20 degrees; it must not be lower than 15 degrees, otherwise the seedlings may be frostbitten or frozen to death.

2. Land preparation and fertilization

While raising seedlings, the field to be planted should be prepared. Asparagus is a perennial crop, so deep plowing should be carried out before planting to ensure the field soil is sufficiently fertile and has strong ventilation and permeability.

The soil pH should not be too acidic or too alkaline; it should remain neutral. Therefore, when the pH is unsuitable, neutralization should be done properly. Asparagus has very poor tolerance to waterlogging, so drainage ditches should also be dug to facilitate later drainage. During land preparation, apply sufficient base fertilizer at the same time to improve soil fertility and promote the growth of asparagus seedlings.

3. Field management

After planting, the goal should be to cultivate the growth of the asparagus roots. If the asparagus is too thin and small, promptly increase the nutrient ratio. Also do a good job of intertillage and weeding, and apply additional fertilizer appropriately according to soil fertility and asparagus growth conditions. Pay attention to drainage after rain, otherwise the asparagus roots can easily rot.

Around September is a relatively important period in asparagus growth, and nutrient demand also increases greatly, so attention should be paid to timely nutrient supplementation. During harvest, water reasonably to keep the soil moist and prevent asparagus from drying and cracking due to lack of water.

4. Pest and disease control

Spring is also the season when various pathogens and pests regain their vitality, so the incidence of disease in asparagus in spring is very high. Pest and disease control in spring is an essential management task. While strengthening field management and doing a good job with water and fertilizer, the asparagus field should also be disinfected regularly. You should understand the common pests and diseases of asparagus well, and then carry out pest and disease control purposefully and in a targeted direction. If disease occurs, promptly remove the diseased plants, then investigate the cause and apply the appropriate treatment.

The above is a brief introduction by Tuliu.com to spring planting techniques for asparagus. Asparagus has relatively weak disease resistance, so in spring attention should be paid to doing a series of management tasks well to avoid unnecessary losses.
