Key points of asparagus management in spring

Asparagus is our common vegetable in spring, generally can only be eaten every year, its nutrition is much more than ordinary vegetables, but also can improve immunity, prevent high blood pressure and heart disease, is very popular in the market. As the temperature gradually picks up, the dormancy of asparagus begins to end, which is also the best time to sow asparagus, so how to manage asparagus in spring? Let's take a look.

1. Clear the garden thoroughly

After thawing in spring, asparagus began to sprout, but the underground sources of diseases and insect pests also began to wake up. Thorough cleaning of the garden in spring is the key measure to prevent asparagus stem blight and root rot. All fields that suffered from stem blight and root rot last year must clean up the infected asparagus, burn it centrally or bury it deeply, and should not smash it back to the field, so as to avoid the harm of germs here. We should pay attention to the depth of asparagus when harvesting, so as not to damage the root disk of asparagus, which is harmful to the growth of asparagus.

2. Watering ridges

For most of the land without winter irrigation and poor soil moisture, it must be watered in time, so as to ensure the quality of ridging and benefit the yield and quality in the later stage. Timely ridging is also an important measure to ensure the quality of asparagus, generally in the first half of the harvest, when the surface soil temperature of about 10 cm reaches more than 10 degrees. The premature ground temperature rises slowly, which leads to the slow emergence of bamboo shoots. the best ridging time is in the middle of March, and the general height is about 30 cm, which can increase or decrease in reality.

3. Topdressing sprouting fertilizer

In order to ensure the yield and quality of asparagus, budding fertilizer must be fertilized in time, should be applied before ridge sealing, and should not be spread before ridge sealing, which will not only waste fertilizer, but also accelerate the speed of root plate on stage. Fertilization is mainly nitrogen fertilizer, generally 8-10 kg of nitrogen fertilizer, 4-5 kg of phosphate fertilizer, 4-5 kg of potassium fertilizer per mu, and 15% of each compound fertilizer containing nitrogen, phosphorus and potassium, 35 kg per mu, and 8-10 kg urea per mu.

4. Pest control

The main diseases are stem blight and root rot, which are the two most common diseases in the whole growth period of asparagus. It is necessary to strengthen field management, increase plant permeability, timely drainage after rain, timely removal of diseased plants when onset, and comprehensive spraying to prevent the spread of the disease. The main pest is bark moth, which usually begins to attack in March and erupts in May. Physical or chemical methods can be used to trap and kill adults, and the root is diluted with phoxim and the effect is better.
