The method of onion hydroponic cultivation is as follows, can onion be hydroponic grown

If you want to hydroponic onions, prepare a large onion, peel off the outer layer of dry skin and cut off the roots with a knife. Prepare a transparent hydroponic container, fill it with water, and place the onion on top, preferably so that its roots are just in contact with the water. At the beginning, you should change the water every day, and after the small roots grow, you can change the water every other day, and change the water every 3-4 days when the green shoots grow at the top.

1. Process the onions.

Before hydroponic onions, it is necessary to choose larger onions, preferably fast-sprouting onions, so that they will sprout faster after hydroponics. The outermost dry skin of the onion can be peeled off by cutting off a part of its roots with a knife.

2. Prepare the container.

Find a transparent hydroponic container, the mouth of the container should not be too small or too large, just enough to jam the onion, you can use a cup, plastic bottle, etc. When ready, fill it with water so that the water is just right at the bottom of the onion, and be careful not to put too much water.

3. Hydroponics.

Put the chopped onion on the hydroponic container, and at the beginning of hydroponics, change the water every day for a week, and then it will slowly grow small white roots.

Fourth, water culture protection.

When it grows roots, the frequency of water change can be extended, you can change the water every other day, about 7-10 days of time, the top of the onion will sprout green shoots, then it is recommended that you change the water once every 3-4 days. If you want it to grow faster, you can add some Raw Leaf Root Rooting Agent to the water, so that it will grow faster.

The method of onion hydroponics is to put the onion directly on the side of a hydroponic vessel, and then it will grow some roots on its own.

Hydroponic chives need to be changed once a day, which can ensure that the growth environment of the plant is clean and tidy, and an appropriate amount of nutrient solution can be added to the water of breeding chives, which is conducive to the growth of chives, but pay attention to the concentration should not be too high, otherwise it will affect the growth of the plant.

Chives like cool climate, cold and heat resistance are strong, daily need to maintain it in the environment of 25 30, winter temperature is too low, plant growth will be affected, need to move it to a warm place for maintenance. Chives require moderate intensity under light conditions, and the tissue is easy to age, increase fiber, and deteriorate in quality under strong light conditions.

Yes

Onions can be hydroponically grown and the method is simple. When hydroponics, prepare a sturdy green onion segment first, cut it from the bottom position, about 6 cm long, pay attention to the root system, so that it is easier to survive.

Then prepare a transparent container with an appropriate amount of water, and then insert the green onion segment face down to submerge the roots in the water. In the beginning, you should change the water once a day, ventilate more, and get more sun, so that you can grow slowly.

Precautions for hydroponic planting of green onions:

1. Bottle handling.

If you want to pour shallots in a beverage bottle, you should choose a bottle with a larger diameter and a certain depth as the container, and then use sharp scissors to cut it from the middle or upper third. Take care to clean the bottle before use to avoid infecting the plant during hydroponics.

2. Hydroponic method.

Prepare the green onion segments. The root is required at the bottom of the segment. Then add an appropriate amount of water to the bottle, turning the roots of the segments downward. Pay attention to the water level. Immersion of the roots of the segment. Otherwise, green onions can rot easily.

3. Change the water regularly.

In the process of hydroponic onions, the water must be changed regularly. In general, it's best to change the water every two days or so to avoid water contamination. Every time the water is changed, a few drops of nutrient solution should be added to the water to meet the growth needs of the green onion. Only with adequate nutrition can green onions grow fast.

Hydroponics of plants is a very popular trend in recent years, and hydroponic plants are not only clean and tidy, but also very ornamental. Plants that are usually hydroponics are daffodils and pothos.

and other ornamental plants, in fact, we can also use the common ingredients around us to cultivate, today I will introduce you to the hydroponic method of onions.

Tool Ingredients: Onion: A hydroponic vessel suitable for the size of an onion.

Method: Read step by step.

Peel off the outer coat of the onion and cut off the roots a little.

Find a glass, preferably a transparent one, which is more ornamental. The mouth of the cup should be able to support the bottom of the onion just right, fill the cup with water, put the onion on the cup, and in the first week, make sure to change the water of the onion every day, and soon the bottom of the onion will grow roots.

In about 10 days or so, we can see that tender green shoots have grown on the top of the onion, and at this time we can change the water every 3-4 days.

In order to promote the growth of onions, in addition to cultivating with water, we can also use fast rooting powder, which can promote the growth of onions faster.

In about 3 weeks, the onion has grown luxuriantly and can be placed on the dining table at home for decoration.

The cultivation method of hydroponic onion is hydroponic method and temperature, etc.

1. Hydroponic method; Prepare a healthy, plump onion ball, peel off the rotten skin, and cut off the undergrown or overly messy roots at the bottom. Then prepare a cup with a mouth slightly smaller than the diameter of the onion ball, and pour it into the mountain and fill it with water. After that, gently place the onion on the rim of the cup so that the bottom of it touches the surface of the water.

2. Temperature: It likes to grow in an environment of 13-22. When maintaining, you should try to keep it in a warm place indoors, which is more beneficial to its growth.

4. Water change: In the week before maintenance, you need to change the water every day. This will allow it to take root faster. When it grows new roots, it can be spikeed and changed to change the water every 2-3 days.

5. Add rooting powder: If it takes rooting too slowly, you can add a small amount of rooting powder to the water. Stir the water well to help it grow faster.

How to buy onions

1. When buying onions, choose onions with the drier the skin, the better, and the tighter the rolling, the better.

2. Looking at its appearance, it is best to see the brown texture in the transparent epidermis, which should be purchased.

3. There are two kinds of onion skin colors: orange and purple, and the onion with orange skin is thicker, has more moisture, and has a crisp taste.

4. The purple skin of the onion has less water, the layer is relatively thin, and the taste is secondary.

5. Relatively speaking, yellow-skinned onions are sweeter, while purple-skinned onions are spicier.

In the method of hydroponic onion, the growth temperature is controlled between 15 and 20, and it is maintained in a semi-shaded and ventilated place. Steps for hydroponic onions: bulb treatment, peeling off the onion coat and cutting off the excess root system at the bottom; Container selection, choose a transparent container that just jams the diameter of the onion; In hydroponics, the water is changed every day for a week before the roots appear, and every three days after the top buds.

Hydroponic onions can generally survive for about 2 months, the temperature of the growing environment should be controlled between 15 -20, the water quality should be kept clean and hygienic during the growth period, and it should be placed in a semi-shaded and ventilated place for maintenance, and the water should be changed about once a week. An appropriate amount of rooting powder can be added to the water to promote the growth of onion roots.

1. Bulb treatment

Before hydroponic onions, select healthy bulbs that are large or about to sprout, peel off the outer coat of the onion, cut off the fibrous roots or poorly growing parts of the bulbs that are too messy at the bottom, and cut off part of the onion roots before hydroponics.

2. Container selection

Choose a transparent glass container, or use a plastic bottle and drinking glass. The caliber of the container should not be too large or too small, and it can be hydroponic if it is just stuck in the caliber of the onion. The height of the water in the container should be at the bottom of the onion, and do not put too much water in it.

3. Hydroponics

Place the processed bulbs in a container and change the water every day for a week before the onion roots appear. After the top buds emerge, change the water every three days and pay attention to ventilation. After the white roots grow, change the water every two days for about 10 days.
