How to arrange asparagus for planting time? Hui Nong Network Xiaobian today will talk about the sowing problem of asparagus and the time of emergence, and will also popularize a small technology about how to build a shed film in the small arch shed asparagus seedlings in spring!
When is the asparagus sowed?
Before planting, the surface of the lotus root is poured into the bottom water, and the seedlings and the row spacing are 10 cm each, and the seed of the germination seed is spotted in the center of the square (the seedlings of the seedlings are seeded in the middle of the nutrient bowl), and then 4-5 kg ​​of phoxim granules per 667 m2, covered with 2 cm thick sieved fine soil.
The soaking time should be 4-5 days before the planned sowing, soaking for 2 days, and germination for 2-3 days. If about 10% of the seeds are germinated, they can be sown when they are white, but if they are not sown for other reasons, the germinated seeds should be placed in the refrigerator for refrigeration.
Generally, the conventional varieties are planted 10 to 15 days after sowing, and the emergence and early seedlings are late and early, depending on factors such as temperature.

How to build a greenhouse film in the small arch shed asparagus seedlings in spring?
In order to raise the ground temperature and maintain the humidity in the small arch shed in spring, the plastic film is covered immediately after sowing. Using bamboo and other supports, insert the two ends of the support into the rafters on both sides at a distance of 50-60 cm to form a small arch shed, then cover the plastic film on the bracket, and tighten it tightly with a soil seal. Excavate a drainage ditch around the seedbed. If it is in an area where the temperature is low at night, in order to improve the heat preservation effect, it can be covered with a grass hoe on the arch shed, and the windy area should also pay attention to prevent the wind smear film.
The temperature in the arch shed is controlled at 23 ° C ~ 28 ° C during the day and 15 ° C ~ 20 ° C at night. After the seedlings are out, the temperature in the arch shed should be observed frequently. When the temperature in the arch shed exceeds 35 °C, the two sides of the arch shed should be uncovered in time to ventilate. In the spring seedlings, the film should be gradually removed as the temperature rises, and it is necessary to prevent the film from being too urgent to cause flash seedlings.
The length of the arch shed is better than 20 meters. Too long will increase the difficulty of ventilation, resulting in high temperature and high humidity in the middle of the arch shed, resulting in burns or serious pests and diseases.
