How to hydroponically cultivate asparagus? You only need to master these four steps!

Asparagus is a common dish on many family tables, but do you know? Asparagus can actually be hydroponically cultivated, so how can it be hydroponically cultivated? What is the method of having it? What are the steps?

Step 1

Sprout

The seed coat of hollow cabbage seed is thick and hard, and it is slow to germinate by direct sowing, so it is appropriate to accelerate germination. Soak the seeds in warm water for about 30 ℃ for 20 hours, filter after soaking, rinse with clean water many times, and then accelerate germination.

Sprouting can be directly wrapped in cloth bags and gauze, and the temperature is controlled at about 25 ℃. When the seeds are white, the seeds will stop sprouting.

Step 2

Sowing seeds

Find a larger flowerpot, water thoroughly, and then spread the germinated seeds evenly in the pot, covering 1-2 cm of soil. In the future, we often use a kettle to spray water to keep the soil moist. To facilitate the emergence of seedlings.

Step 3

Planting

1. Appliance selection: buckets, basins and water tanks can be used as cultivation containers, discarded foam boards as floats, and discarded sponges and wheat straws as fixed seedlings.

two。 Planting and management: when the seedlings grow to 4-5 leaves, they can be planted. Drill a hole in the floating valve, fix 2-3 seedlings into the hole with a sponge and float on the water. In order for asparagus to grow vigorously, you can also add an appropriate amount of nitrogen fertilizer to the water, urea is better and often add water to the container.

Step 4

Harvest

Asparagus is a vegetable crop that has been harvested many times. When the seedling is about 30 cm high, it can be picked. The first pick leaves two nodes at the base to promote the germination of lateral vines. The future harvest, harvest standards and the number of sections left are the same as the first time. Do not leave too many nodes, otherwise the occurrence of too many lateral vines, nutrition dispersion, affecting the quality and yield.

In addition, an appropriate amount of nitrogen fertilizer can be added after each harvest.

Asparagus can be eaten by ordinary people, but because of its cold nature, it is better for people with weak physique, spleen and stomach deficiency and low blood pressure and cold stomach to eat less.
