Hydroponic culture method of asparagus

Asparagus is a kind of vegetable that people like, especially in summer, a large number of it will be on the market, because it is adaptable, sowing and cutting can be normal, and it can grow again after harvest, just like leek, so many people will grow it at home, but the soil is not easy to deal with. In fact, asparagus can be hydroponically cultivated, so how to hydroponically cultivate it? Let's get to know it.

1. Seed germination

The seed coat of hollow cabbage is thick and hard, so if you sow it directly, the germination speed is very slow, so to accelerate germination yield before sowing, you can soak the seeds in warm water of about 30 degrees for about 20 hours, wait for them to absorb enough water, and then fish them out, rinse with clean water many times, and then accelerate germination. Sprouting is to wrap the soaked seeds with cloth bags or gauze, control the environmental temperature of germination at about 25 degrees Celsius, open and rinse once a day, and sow when more than half of the seeds are white and broken.

2. Sowing seeds

Sowing can choose a larger flowerpot, water once before sowing, and then spread the budding seeds evenly in the flowerpot, and then cover the soil 1-2 cm. After sowing, we should often spray water to keep the soil moist, and at the same time control a reasonable temperature to promote the emergence of seedlings.

3. Planting

Planting utensils can choose containers such as buckets, basins or water tanks, foam boards can be used as floating mats, and seedlings can be fixed with sponges, wheat straw and so on. When the seedlings break the soil and grow to 4-5 leaves, they can be planted. When planting, they will drill holes in the floating cushion, plant 2-3 seedlings in each hole, and then fix the seedlings with a sponge to make them float on the water. Asparagus can not grow without fertilizer, so an appropriate amount of nitrogen or organic fertilizer can be added to the water to make it grow vigorously.

4. Harvest

Asparagus can be harvested many times, generally growing to about 30 cm in the current period can be picked, the first picking to leave two nodes at the base, which can promote the germination of lateral vines. The same is true for each harvest in the future, do not leave too many nodes, this will sprout too much to the side vine, will consume a lot of nutrients, resulting in nutrition dispersion, affecting the quality and yield, fertilizing once after each harvest.
