How to grow onion potted plants with water, how to grow hydroponic onions

Onions are cultivated in all parts of my country in the north and south, and are one of the main vegetables in our country, onions can sterilize and prevent colds, and can also lower blood pressure and blood sugar, and help digestion. But you know what? Onions can actually be grown in pots at home, so how to grow potted onions?

First, * training methods.

Some friends who like to eat onions buy a lot of onions at home at one time, and the onions will rot secretly. Don't throw it away because you can't eat it, in fact, it still has use value, you can remove the rotten part of the onion, plant it in a pot, and eat it slowly when it grows!

1. First of all, remove the rotten part of the onion, peel off the outermost layer of skin, and keep the roots at the bottom, taking care not to break it.

2. Prepare flower pots and soil, flower pots should ensure that there is enough space, use ordinary soil, install them in 1 3 places, water some soil soil, not too much, and keep the soil moist.

3. Plant the onion root down and put it in the pot*, you don't need to bury the onion whole, just put it on the surface of the pot*.

4. In this way, after two or three days, the root system of the onion will grow, and the onion potted plant will survive.

2. Hydroponic methods.

Potted onions can not only be cultivated, but also hydroponics is simple. Just prepare a clear glass bottle, an onion, and an appropriate amount of water.

1. Wash the prepared glass bottles, clean the onion roots, remove the broken rotten roots, avoid breeding germs, infecting the onion, and affecting survival.

2. Pour water into the glass bottle, place the onion on the mouth of the glass bottle, and let the root system of the onion submerge into the water.

3. During the maintenance period, it can be moved to the balcony to let it receive some light properly, and the water can be changed regularly to ensure that the water quality is clean. After a few days, the root system at the bottom of the onion not only grows, but also grows some small fibrous roots, and green shoots sprout on the top of the onion ball. At this point, the hydroponic onion has survived.

Onions can also be used as potted plants.

Methods: 1. Select whole onions as materials;

2. Prepare a container full of water, cut off the fibrous roots of the onion and put it on the mouth of the container, and the water surface can touch the bottom of the onion;

3. In the early stage of hydroponics, it is necessary to apply phosphorus fertilizer every half month to make the flower buds early pregnant;

4. When the height of the blade reaches 20 cm, it is necessary to spray chlormequat to control the height;

5. Hydroponics needs to be maintained in full sunshine, which can not only make the leaves not grow but also bloom early;

6. Change the water frequently, cut off the dry and rotten roots, and keep the water clear without good cavity bacteria and socks.

To plant potted onions, you should use loose, fertile and well-drained soil as a cultivation medium, buy onion bulbs from the market, and then bury them in the potting soil, water them once after planting, apply thin fertilizer frequently during the growth period of potted onions, and maintain them in a sunny place every day, so that potted onions can grow vigorously.

1. Prepare the soil

If you want to plant potted onions, then you need to prepare the right soil first, it is best to use loose and fertile and well-drained soil to plant, which is most conducive to the growth of onions, the soil can be mixed with some base fertilizer, which can improve the fertility of the soil, and then put the soil into pots for planting.

2. Planting method

Buy onion bulbs from the market, remove the dry skin, and then bury them in the soil, pay attention to the need not to plant too deep, it is best to make its top exposed soil surface, which is conducive to the germination of onions, after planting well, you need to water appropriately, and it is most appropriate to keep the soil slightly moist.

3. Water and fertilizer management

Potted onions need to be maintained and managed after planting, and they need to apply water and fertilizer reasonably every day, and they need to be hydrated in time when the soil is dry, but they can not be watered too much, and when the potted onions grow, they should be applied some thin rotten liquid fertilizer, so that the onions can grow vigorously.

4. Sufficient light

When potted onions are cultivated, they also need to be given sufficient light, so they need to be maintained in a well-lit environment to facilitate their photosynthesis, but it should be noted that onions are not heat-resistant, so when planting in summer, they need to be shaded and cooled to avoid onions being exposed to the sun.

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 early preparation, when hydroponic onions, the plastic bottle needs to be cut horizontally, and then the shallots should be cut from the root more than five centimeters; In the hydroponic method, a small hole is dug in the middle of the foam board, the green onion roots are buried in the foam board, and put into a plastic bottle; Change the water regularly, and when maintaining the onion in the later stage, you need to change the water every 2 3 days to ensure that the water quality is clean and hygienic.

Before cultivating shallots with water, prepare a transparent plastic bottle and grow strong seedlings, use scissors to cut the plastic bottle horizontally, keep only the lower part, and then cut the shallots from the root more than five centimeters, and only keep the lower part of the green onion for later use.

When hydroponics of green onions, you need to choose a foam board, dig a hole in the center, and then bury the roots of the green onion in the foam board, and then you can place the processed from the root down, place it in a plastic bottle, and inject non-polluting mineral water, and the water surface can be less than half of the plastic bottle.

In the process of hydroponic shallots, it is necessary to change the water regularly to avoid the growth of a large number of bacteria in the water and affect the normal growth of shallots. If tap water is used, it is necessary to let it stand for 2 to 3 days in advance, and then use it after the chlorine in the water is completely volatilized.

In the process of hydroponics, it needs to be placed in a sunny environment for maintenance, and given all-weather astigmatism to keep the leaves in a green growth state. When the light is too strong, it needs to be transferred to a astigmatism environment in time to avoid the strong light affecting the growth of the plant in the later stage.

1. If you want hydroponic onions, you must first prepare a large onion, peel off the outer layer of dry skin, and cut off a section of the root 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 touching 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.

2. 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.

3. 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 high enough to touch the bottom of the onion, and be careful not to put too much water.

4. Hydroponics.

Put the chopped onion on the hydroponic container, and when you first start hydroponics, you need to change the water every day for a week, and then it will slowly grow white roots.

5. 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, add some rooting powder to the water so that it will grow faster.

6. The above is the method of hydroponic onion.
