Grow asparagus with this technique for a high yield in just one year

Today let's talk about asparagus growing techniques. Asparagus can be harvested continuously for ten to fifteen years from a single planting. In the south it can grow all year round, while in northern regions it goes dormant in winter. It will continue growing the following year. Asparagus has strong adaptability, is easy to cultivate, and has no strict temperature requirements. In winter, the underground part can withstand temperatures as low as minus twenty degrees in the soil, and during the growing season it can tolerate high temperatures of thirty-seven degrees. In cultivation it also has the advantages of requiring little labor and giving high yields.

Asparagus growing techniques

1. Seed treatment

Before sowing, soak the seeds in warm water at twenty-five to thirty degrees for three to five days, changing the water once or twice a day. Once the seeds have finished absorbing water, remove them, mix them with fine sand or vermiculite, put them in a container, cover with a wet towel, and place them at twenty-five to thirty degrees to promote sprouting. Turn them twice a day. After about a week, once the seeds show white sprouts, they can be sown.

2. Seedbed preparation

The seedbed should be chosen as fertile, loose sandy loam. For one mu of seedbed, apply two thousand five hundred to three thousand kg of decomposed organic fertilizer, twenty kg of diammonium phosphate, and fifteen kg of potash fertilizer. After plowing them into the soil and finely preparing the land, beds can be made. The bed width is one point three to one point five m. For sowing, open furrows across the length of the bed, with a row spacing of twenty to thirty cm and a plant spacing of seven to ten cm. Use a dibber to make holes, sow one seed per hole, cover with two point five cm of soil, then cover with a thin layer of straw to increase and maintain temperature. The sowing time is from late April to early May.

3. Raising seedlings in a greenhouse

1. Preparing the nutrient soil

Thirty percent decomposed farmyard manure, thirty percent peat, twenty percent aged stove ash, and twenty percent farm field soil. Add fifty grams of diammonium phosphate per kg of nutrient soil. For seedling raising in nutrient pots, sow one seed per pot, at a sowing depth of two cm, cover with two cm of soil, and water thoroughly.

2. Management of temperature and humidity

The suitable temperature for asparagus germination is twenty to twenty-eight degrees. After emergence, keep it at twenty-five degrees; the maximum must not exceed thirty degrees, and the minimum temperature must not be lower than eight degrees. Keep the soil moist. After emergence, the seedling root system is weak, so water promptly during drought and weed promptly. One week before transplanting, begin ventilating to harden the seedlings so they adapt to the external natural environment, achieving the goal of strong seedlings.
