Asparagus planting method

Asparagus, also known as asparagus or asparagus, its tender young stems can be eaten as a vegetable. Because of its rich nutrients and excellent health functions, asparagus is known as the "king of vegetables" and occupies an important position in state banquets. Growing asparagus has high economic benefits. Learn the whole process of asparagus planting below.

1. Seedling stage

Seed treatment: Before sowing, air the seeds and then soak them in warm water at 30℃ for 2-3 days. During the soaking process, gently rub the seeds to remove the wax on the surface. On the second day of soaking in clean water, add carbendazim. After 12 hours, rinse with clean water and dry for later use.

Seedling time: Asparagus can be grown in the open field in spring, summer and autumn, but there is no seasonal restriction in the greenhouse.

Seedling raising method: Choose fertile, loose sandy loam as the seedbed to reduce damage during transplanting. Apply an appropriate amount of well-rotted farmyard manure and triple compound fertilizer in the seedbed. In addition, other methods such as sunbed seedling cultivation and nutrient pot seedling cultivation can also be used.

2. Seedling Management

Water and fertilizer management: Ensure sufficient water supply during the seedling stage, but avoid large-scale flooding. When the seedlings are 10 cm tall, start applying nitrogen-based fertilizers , and you can also apply 500 times diluted biostimulants.

Weeding: Asparagus seedlings grow slowly, the spacing between plants is small, and they are easily attacked by weeds. Weed frequently and take timely measures to control pests such as thrips, aphids, mole crickets and cutworms.

Soil management: Mainly prevent water accumulation in the field, and do a good job of soil cultivation in the later stage to prevent lodging.

3. Planting

When the asparagus seedlings have more than 3 above-ground stems, they can be transplanted and planted. When transplanting, water the plants sufficiently and transplant them with soil to minimize root damage.

Before planting, the selected land should be deeply plowed and carefully cultivated, and sufficient base fertilizer should be applied. When planting, arrange the seedlings in the furrow at a spacing of 30 cm, with one plant per hole. One end of the scale buds on the underground stems of each seedling must face the same direction along the ditch and be arranged in a straight line to concentrate the growth position of the tender buds and facilitate soil cultivation.

4. Field Management

Timely replanting: Within 1 month after transplanting, replant the areas with missing seedlings and broken ridges in time to ensure yield.

Intertillage and soil cultivation: The row spacing of asparagus cultivation is large, the plants are small in the young stage, the coverage is low, and weeds are easy to grow. Pay attention to timely removal of weeds. After each tillage, the planting furrows should be covered with soil in stages until the underground scales are buried below 15-20 cm to inhibit the growth of weeds between ridges.

Water and fertilizer management: Asparagus seedlings have a long growth period and produce many tender stems, so it is necessary to ensure adequate nutrient supply. When the asparagus sprouts tender stems after planting, apply nitrogen fertilizer and balanced compound fertilizer, and apply Sea Elf biostimulant to help it grow quickly. After that, top dressing should be carried out every month, and the amount of fertilizer can be increased appropriately. When asparagus enters its vigorous growth period in autumn, it is necessary to apply autumn fertilizer, which is generally organic fertilizer + balanced compound fertilizer + cake fertilizer, etc., applied through furrows to lay the foundation for an early bumper harvest next year. After entering the mature stage in the second year, focus on applying germination fertilizer, bamboo shoot fertilizer and autumn fertilizer. Germination fertilizer and autumn fertilizer are organic fertilizer + balanced compound fertilizer, and bamboo shoot fertilizer is mainly high-nitrogen quick-acting fertilizer, combined with Linhai Elf biostimulant.

5. Harvest

The harvest period of asparagus is relatively long, generally between April and August. When harvesting, pay attention to applying relay fertilizer. Stop harvesting when there are only 5-7 bamboo shoots waiting to germinate in the bud tray to avoid affecting next year's bamboo shoot harvest.

The above is an introduction to the cultivation technology of asparagus. As a vegetable with high health value, asparagus has very good market prospects and prices.
