How to grow onions How to grow onions in pots

1. Prepare an onion that has sprouted.

2. Peel off the skin of the onion, taking care not to touch the onion roots.

3. Cut the onion, taking care not to cut the sprouted part of the onion.

4. Peel off the excess part of the onion, leaving only the most central part that sprouts. If the onion is not bad, the peeled part can be eaten without wasting at all!

5. Prepare the container, fill the soil, plant the peeled onion heart with the roots facing down, pour water, and put it on the windowsill to receive light.

6. The leaves of the onion are edible, similar to shallots, and can be used for stir-frying, or they can be eaten with dipping sauce. When the onions are ripe, you can see the onions arching out of the soil, and the onion fruits can be harvested.

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.

Land selection: Loosen the soil and expose it to the sun for 5-7 days. Prepare the seeds:

Onion planting should be done with plump seeds. Sow the seeds into the soil: Water the furrow surface well, sprinkle the seeds evenly, and then cover the soil with a thin soil.

Field management: Water every 10 days during the growing period and reduce the amount of water near the harvest time.

1. Land selection and land preparation

Onions have strong adaptability to the environment and can grow on most soils, but it is advisable to have fertile and loose soil, before planting, the land should be prepared first, and then exposed to the sun for 5-7 days after loosening to eliminate the germs and insect eggs.

2. Prepare the seeds

When planting onions, it is necessary to choose plump seeds, in order to improve the germination rate, the seeds need to be sprouted, soaked in warm water, fully absorbed and then taken out to dry, and wrapped in moist gauze, placed in a warm environment, and can be sown after the seeds are exposed.

3. Sow seeds into the soil

Water enough water on the furrow surface, sprinkle the onion seeds evenly, then cover with 1 cm of thin soil, and then cover with a layer of plastic film, keep the temperature at about 20, and it will germinate after a week.

4. Field management

During the growth period of onions, generally water once every 10 days to promote development, when it enters the bulb expansion period, increase the frequency of watering, water once every 5 days, close to the harvest period, reduce the amount of watering, and gradually stop watering.

The planting method of onion is: furrow fertilization, seed germination, and uniform sowing.

1. Fertilize furrows.

Before planting onions, it is necessary to choose a sunny plot, and then make a furrow, the furrow is high, the furrow is 27cm wide, and the furrow surface is leveled after applying phosphorus and calcium, and the organic soil miscellaneous fertilizer that is well decomposed is used as the base fertilizer, and then the fertilizer and soil are mixed evenly.

2. Seed germination.

Before planting onions, the seeds should be germinated, soaked in cold water for no more than 12 hours, and then wrapped in a damp cloth and placed in a place of 20-24, during which Zheng Kong should be washed with water every day, and sown in time when the seeds have just been exposed.

3. Evenly shout and fight blind seeding.

After the soil is ready, evenly sprinkle onion seeds, and start transplanting when the seedlings grow to 5cm, silver is generally planted with a row spacing of 20cm, plant spacing of 16-17cm, and a density of 20,000 plants per mu, pay attention to the selection of healthy seedlings.

Field management techniques for onions

1. Scientific water use.

After about 20 days after the onion is planted, it enters the slow seedling stage, because the temperature is low at the time of planting, so it can not be watered in large quantities, and too much watering will reduce the ground temperature, so that the seedlings slow down. At the same time, the new roots of the newly planted seedlings have not yet germinated, and there can be no shortage of water. Therefore, at this stage, the number of watering of onions should be more, and the number of watering should be small, and the general principle of mastering is not to wilt the seedlings, and not to dry the ground, so as to promote the rapid rooting and survival of the seedlings.

2. Fertilization. After transplanting, dilute human and animal manure water should be applied once 7 days, and high-quality soil miscellaneous fertilizer should be applied once every 7 to 8 days to promote rooting and enhance cold resistance. In the severe cold season, onion seedlings grow slowly, and top dressing can be suspended.

By the end of February of the following year, when the bulb enters the expansion period, fertilizer should be reapplied 1-2 times, and 10-12 kg of urea plus 5-6 kg of potassium sulfate should be applied per mu. In late March, the bulb expanded rapidly, and 1250 kg of decaying manure per mu was applied, and fertilization was stopped 25 days before harvest.
