From left to right, the 1-day, 4-day, and 8-day hydroponic onion potted plants in the picture above).

Green onions are very easy to grow in water, if you buy fresh green onions can not be eaten in time, you do not necessarily have to put them in the refrigerator, you can soak them in shallow water, the preservation effect is better.

Hydroponic onion potted plants should be placed on a sunny windowsill or balcony, and can be raised in transparent glass bottles or cups.

Of course, you don't need to leave so much like the picture above, just a little about 5 centimeters, and the green part is about 3 centimeters.

2. Start hydroponics.

Just find a clear, clean cup or glass bottle to let the sunlight through, and fill it with water up to half of the rhizome of the onion.

Keep the rhizome and put it in clean water again for hydroponics, after rooting, you don't need to change the water every day, and the water becomes slightly turbid and then change the water.

Note: Although the leaves of green onions can be regenerated, they are not regenerated indefinitely, and you can pick them about 3 times at most, but it is also good to maintain them as a potted plant.

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.

Scallions, also called guanpu, guancao. It belongs to the sedge family, perennial root, and is a watery herb; The plant is 1 2 meters tall, and the stem is tall and straight, much like an edible green onion, but it is not edible. Generally in nature, it often grows in shallow water in swamps, ditches, ponds, and lakes.

Artificially cultivated shallots, when the weather is getting warmer in early spring, the overwintering seedlings can be dug up from the ground, part of the soil is shaken off, and the underground stems are divided into several clusters with pruning shears or shovels, and each cluster has 5 8 stems; Plant it in a pot without a drain hole, and keep the potting soil with a certain humidity or shallow water, and it can germinate in 10 to 20 days. If cultivated in the open field, it is advisable to maintain 8 12 buds per bush. After planting, the soil is compacted and filled with water.

Linong beating music to treat the shallots is good, I didn't have shallots in the field, the shallots started last year, I used a lot of medicine, and I didn't see any effect, this year's beating, the shallots are very clean, and it is really good.

Daily water breeding onions, you need to cut off the green onion leaves first, leaving the green onion white with the root system, and then tie the processed green onions together and put them into the container, the water level should not be too high, just submerged to the green onion roots, pay attention to the best use transparent container breeding, during the need to change the water frequently, and it is best to put the green onion in a semi-shaded and ventilated place for water raising.

1. Treatment of green onions

The correct way to raise onions in water is to first treat the green onions, buy the green onions with roots from the market, and then cut them from the green parts, leaving the green onion roots with the white onions, and then you can gently bundle the processed green onions together with a rubber band, so as to avoid lodging when the green onions are raised in water.

2. Water quality containers

When raising onions in water, it is best to use transparent containers to breed, so that it is convenient to observe the growth of onion roots, after the container is cleaned, you can prepare to add water to raise onions, note that if you use tap water to raise onions, then it is best to let the water stand for a while, and wait until the chlorine in the water volatilizes before use.

3. Hydroculture method

Put the treated green onion root down into the container, and then add an appropriate amount of water, pay attention to the water level should not be too high, generally submerge to the root system of the green onion, and move to the incision of the green onion can not contact the water, otherwise the green onion is easy to rot, and the water needs to be changed frequently during the maintenance period to ensure that the water quality is clean and clean.

4. Precautions

There are no nutrients in the water to grow onions, so when raising onions in water, it is necessary to pay attention to adding a few drops of nutrient solution to the water regularly, and the onions need to be placed in a semi-shaded and ventilated environment during the maintenance process, so that they can be irradiated with an appropriate amount of scattered light, and they should be harvested in time after the green onion leaves grow.

Shallots cannot be raised in water; Due to the shallow root distribution and weak absorption of onions, they are not tolerant to thick fertilizer, drought and waterlogging, and have poor competitiveness with weeds.
