Growing asparagus with this technique can lead to a bumper harvest in a year.

Today, let's talk about the planting technology of asparagus. Asparagus can be harvested continuously for 10 to 15 years at a time. It can grow all year round in the south, but it will go dormant in winter in the north. It will continue to grow in the coming year. Asparagus has strong adaptability, is easy to cultivate, and has no strict requirements on temperature. The underground part of asparagus in winter can endure a low temperature of minus 20 degrees in the soil and a high temperature of 37 degrees in the growing period. There are also advantages such as less labor and high yield in the cultivation summary.

Planting techniques of asparagus

I. seed treatment

Soak the seeds in warm water ranging from 25 degrees to 30 degrees for three to five days, change the water once or twice a day, fish them out after the seeds are absorbed, stir them with fine sand or vermiculite, put them in a container, cover them with wet towels, and place them at 25 degrees to 30 degrees Celsius to promote germination. Turn twice a day and sow seeds after about a week of exposure.

Second, seedbed preparation

The nursery bed should be selected in the fertile and loose sandy loam. One mu of the seedbed should apply 2500 to 3 kilograms of rotten organic fertilizer, 20 kilograms of diammonium phosphate and 15 kilograms of potash fertilizer. After ploughing into the soil and fine soil preparation, the bed can be used as a bed. The width of the border is 1.3 to 1.5 meters, and the vertical border and horizontal trench is used for sowing. The row spacing is 20 to 30 centimeters, and the plant spacing is 7 to 10 centimeters. Covering 2.5 cm of soil and then covered with thin grass can increase the temperature and keep warm. The sowing time is from late April to early May.

3. Raising seedlings in greenhouse

1. Preparation of nutritious soil

Mature farm manure 30%, peat 30%, old furnace ash 20%, farm field 20%, 50 grams of diammonium phosphate per kilogram of nutritious soil. Raise seedlings in nutrition bowls, sowing one seed in each bowl, sowing two centimeters deep, covering soil two centimeters, and watering thoroughly.

2. Management of temperature and humidity

The suitable temperature for asparagus germination is 20 to 28 degrees, 25 degrees after emergence, the highest can not exceed 30 degrees, the lowest temperature is not less than 8 degrees, the soil remains moist, the roots of seedlings are weak after emergence, and the seedlings should be watered and weeded in time in case of drought. A week before the fixed value, begin to ventilate and refine the seedlings to make them adapt to the external natural environment and achieve the goal of healthy seedlings.
