Can onion roots grow shallots, and are onions grown from onions shallots

The method of cultivating and replanting green onion roots is actually very simple, the green onions we buy in our lives, the green onion roots should not be all removed, you can cut off the upper end of the green onion short root 3 cm, the upper end of the green onion white and green onion leaves can be kept for eating, and the remaining green onion roots can be used as a base for regenerating green onions; First of all, it is necessary to sort out the collected onion roots, and the onion roots can be placed in the sun to dry for two or three days, the purpose is to sterilize the onion fungus with light to prevent the onion from being brought into the new planting land with soil-borne diseases; After the green onion root is dried, then prune the roots, because the roots that are too long and too many are worthless, you can prune the green onion roots to about three or four centimeters, which is conducive to planting and shortening the stem meristem and fibrous roots; Then soak the green onion root in clean water for 12 hours, pay attention to as long as the short stem is submerged in the water, do not let the upper end of the short stem green onion white into the water, the purpose of this is to help the short stem absorb water and awaken the root to improve the survival rate; After the green onion root awakens, it can enter the planting stage; In the prepared field, bury the green onion roots into the soil about centimeters, and the green onions are white to expose the soil centimeters; The row spacing is 70 cm, and the plant spacing is 5 cm. Immediately after the green onion root is replanted, water it with a small amount of water.

Moist soil to ensure the water needed for the growth of onion roots.

OK! You can pluck the upper part and keep the roots to plant in Shili, but at most you can eat one stubble, and you can buy seeds to plant green onions!

Yes, you bury it in the soil, water it a little, and it will grow slowly.

The onion that grows from the onion is notShallots

While both onions and shallots belong to the lily family.

Allium plants, and the onions that grow on the onions look very similar to the appearance of shallots, but the two are actually different plants, among which shallots are also known as chives, four seasons onions, etc., and their rhizomes are relatively small.

It should be noted that if the onion has grown green onion buds, then the nutrients in the onion bulb part will be transferred to the top for the sprouts to grow, so its nutritional value will also decline to a certain extent. The part that grows from the onion is basically not eaten, and the main part eaten is its round bulb.

Features of onions

1. Although the onion seedlings are not green onions, they can also be eaten as green onions, if the purchased onions germinate and can be planted in flower pots, seedlings can grow after a few days, and they can be cut off a little when stir-frying, and they are very fresh in the dish, because onions are also a variety of green onions.

2. Onions like to grow in a cool and dry environment, and generally the seeds can germinate at a temperature of about 4 degrees. However, the most suitable germination temperature is still about 16-17 degrees, and the suitable temperature for the growth of seedlings is about 12-20 degrees.

The seedlings that grow from onions are not green onions. There is still a difference between onions and chives, they are different plants. Both chives and onions belong to the lily family, but the bulbs of onions are large, while the bulbs of chives are small and predominantly white, which is what we call lily white.

Even if we put regular chives in the ground, they will still grow.

There are no bulbs as the two are different plants. And the taste of the two is also very different. The flavor of the onion is predominantly spicy and appears as a side dish. Chives are often used as a condiment.

Growing environment

Temperature. Onions are more adaptable to temperature. Seeds and bulbs can germinate slowly at 3 5, 12 begin to accelerate, the growth of temperature-appropriate seedlings is 12 20, leaves are 18 20, bulbs are 20 26, and robust seedlings can tolerate low temperatures of 6 7.

The bulb needs a higher temperature to swell, and the bulb cannot expand below 15, and the growth of 21 27 is the best. If the temperature is too high, it will grow and decline and enter dormancy.

Illumination. Onion is a long-day crop that requires more than 14 hours of sunshine during bulb swelling and flowering. Under high temperature and short day conditions, only leaves grow, and shallots cannot be formed. Onions are suitable for light intensity of 24,000 lux.

Moisture content. Onions should be supplied with sufficient water during the germination stage, the peak growth period of seedlings and the bulb expansion stage. However, it is necessary to control the water at the seedling stage and before overwintering to prevent the seedlings from growing and suffering from frost damage.

Irrigation should be controlled 12 weeks before harvest to enrich the bulb tissue, accelerate maturation, and prevent the bulb from cracking. Onion leaves are drought-tolerant, suitable for 60% to 70% humidity, and the air humidity is too high to cause diseases.

The onion sprouts and grows onion heads.

Extended Links. Onion storage method.

There are those with leaves braided for storage, and there are also those with leaves removed to store shallots.

1) Hang the pigtail on a wooden frame without touching the ground, and surround it with a mat to prevent rain or flooding, and do not invert during storage. The effect of this method is poor, and it will sprout one after another after the dormant period, and it can generally only be stored until the National Day on the market**, but the ventilation is good and the rot is less. This is a widely used method of home storage.

2) Stacking This method should be tightly sealed to prevent sun and rain and keep it dry. At the beginning of the stacking, the stacking is reversed 1 or 2 times according to the weather conditions to remove the hot and humid air in the stack. Carefully inspect after every rain, and if there is any leakage, it should be opened to dry.

After storage in October, it should be covered with a straw curtain for insulation, and cold areas should be transferred to the warehouse for storage to prevent freezing. Practice has shown that as long as the heart of the onion is not frozen after freezing, it can still be restored to its original state after thawing. (3) Controlled atmosphere storage can be carried out in room temperature cellar (warehouse), shade shed or cold storage.

If it is dried shallots, it can be packed into baskets or boxes, stacked in the shade, and closed with plastic film tents before the release period, with 500 1000kg per stack. In storage, natural O2 was lowered to maintain O2 at 3% 6% and CO2 at 8% to 12%, and the effect of inhibiting germination was very good. During storage, try not to open the account for inspection, so as not to quickly cause germination due to the increase of O2 content.

The size of CO2 concentration had little effect on the quality of onions, and it was mainly the outer cortex that played a protective role in the internal scales. The effect of O2 concentration is great, and when the concentration increases, the germination rate increases significantly, but long-term O2 deficiency will also cause the roots of shallots to become soft, sunken, and the scales are blue-green, which eventually leads to necrosis. When using plastic film for closed storage, the onion is often infected with mildew due to the large temperature difference in the storage environment, resulting in condensation in the tent.

Chlorine gas is commonly used for antiseptic, the dosage is air volume, and the pesticide is applied once every 5 7 days, and excessive amount is easy to cause pesticide damage. (4) Cold storage storageCold storage storage is a better storage method for onions at present. When using this method, the onion must be stored in storage before the onion is out of dormancy in mid to late August.

Baskets are stacked or stored in racks, or packed into plastic bags for rack storage or palletized storage. In Shenyang, it is mostly stored in the garlic sprout storehouse. It is maintained at a temperature of about 0°C and can be stored for a long time.

However, the humidity of refrigeration is generally high, and the bulb often grows adventitious roots.

The growth process of green onion is: germination stage, seedling stage, formation stage, and dormancy stage.

1. Germination period

The germination period of green onion is from sowing to cotyledons, which are all germination stages. 7-10 days after the germination of the seed, the radicle stretches out, penetrates into the middle, the cotyledons elongate, and the waist arches out of the ground, that is, the "nose".

Then, the top of the cotyledons grows out of the surface, straightened, that is, "straight hook", and then the first leaf grows from the leaf outlet.

2. Seedling stage

Green onion seedling stage, seedling stage, from cotyledons straight hook to planted seedlings. It can be sown for up to 8-9 months in autumn.

Usually the seedling stage of autumn sown green onion is divided into three stages: pre-winter, winter and post-spring. In the first 40-50 days of winter, the overwintering period is 120-150 days, and the rejuvenation period is 80-100 days. During the sowing period of 80-90 days, spring-sown green onions quickly enter the vigorous growth period after emergence.

3. Formative period

The formation period of green onion is 120-140 days, which can be divided into two stages: slow seedling and summerization, the formation period of green onion and the fullness period of green onion.

4. Dormant period

There was no obvious physiological dormancy period in the dormant period of green onions, and green onions in northern China were forced to enter dormancy under low temperature conditions, and the dormant period was 120-150 days. After the temperature rises in spring, the plants begin to grow green.

After the onion sprouts, the sprouts that grow are edible.

After the onion sprouts, it will not produce solanine or aflatoxin toxic substances like potatoes or peanuts, and it will not have a toxic effect on the human body after eating, so it can be eaten with confidence.

Onions are more drought-tolerant, so even in a dry place, they can generally maintain a good degree of freshness, so they need to be placed in a cool and dry place when preserving, if placed in a humid and warm place, it is easy to cause germination or mold, affecting the quality of the onion.

The green onion is divided into green onion and shallot, their appearance is somewhat similar, the green onion plant is about 50 cm and the stem part accounts for more than half, its leaves are relatively wide and thick, the stem and leaves of the shallot are very evenly distributed, its stem is white, the leaves are green and hollow, and the outside of its stem is wrapped in a reddish-brown film.

Green onion is a common ingredient used as a spice in life, some people don't know what the green onion looks like, it is divided into three parts of rhizomes and leaves, there are two kinds of green onions and shallots on the market, the green onion plant is longer and very thick, about 50 centimeters, its stem is white, the leaves are green and thick, and the green onion is mainly used for its stem.

The shallot plant is relatively short and only about 20 cm, each shallot is very slender, the stem and leaves each account for half of the whole plant, the stem is white in the state, the leaves are green, the leaves of the shallot are empty in the heart, its root system is relatively short and shallow, there are more shallots in clusters, and there is a reddish-brown film on the outside of its stem.

In life, green onions are mainly used to make dumpling filling, stew some meat dishes, northerners prefer to eat green onions, shallots are a kind of fragrant ingredients, no matter what dishes can be added to make some shallots more attractive, the vegetable fragrance is stronger, shallots can also be used to fry eggs to eat, shallots are more popular in the south.

Regardless of the large traces of green onions or shallots, they have played an important role in life, especially in the production of dishes to reflect the value of their existence, the adaptability of green onions is very strong, environmental changes have little impact on it, the average person can eat, but some people do not like its fragrance, so whether to eat green onions varies from person to person.

Yes, only green onion leaves and shallots are harvested at harvest time.

It will continue to grow, but usually only shallots.

In this way, green onions are generally harvested only once.

Expansion: How to grow green onions:

1. First of all, we must understand the growth habits of green onions. Green onions prefer to survive in a cool environment and are very hardy, but not tolerant to high temperatures, and are suitable for growing in temperatures between 15 and 25 degrees. In addition, green onions are also very drought tolerant, its green onion leaves have wax powder, the distribution of the root system is shallow, and the water absorption is poor.

Green onions have strong adaptability to the soil and prefer to be planted on fertile, deep, well-lit, well-drained, and well-permeable land.

2. Green onions are suitable for planting in spring and autumn. It is especially suitable for planting in autumn, where the temperature is perfect for the growth of green onions. Green onions are planted in March to April in the spring and September to October in the fall.

3. Choose suitable varieties for the planting of green onions. There are several issues that need to be paid attention to when choosing varieties: first, whether the local environment is suitable for green onion planting; second, whether there is a demand for green onions in the local market; The third is to understand the quality of green onions.

Considering these three points, green onions can be planted well, and there will be a good harvest in the later stage.

4. The planting of green onions should do a good job in seedling raising. When choosing fertile, deep, suitable light, strong drainage, and good air permeability for planting, it is necessary to avoid heavy planting of green onions. Before planting, the land must be turned over, and the fertilizer should be applied sufficiently, so as to ensure the looseness of the soil and good drainage, and wait until the green onions are seedlings after the emergence of water and fertilizer management in the field, chasing 5 kg of urea.

Wait until late October before transplanting and planting.

5. Do a good job in field management for the planting of green onions: regularly check whether there are missing seedlings and dead seedlings in the field after transplanting, and replenish the seedlings in time. At the seedling stage, it is necessary to control the amount of watering to avoid the situation that the rotten roots of green onions are still growing.

At the seedling stage, weeding should be carried out 2 to 3 times, together with tillage, so as to improve the ability of land moisture conservation. The problem of physical examination fertilizer and water management can not be ignored, it is not appropriate to water a large amount of water, and it is necessary to water according to the soil and seedling stage. Twenty days before the green onion harvest.

Stop watering before. In summary, green onion planting should be done well to apply fertilizer 4 to 5 times during the planting period, and at the same time with watering. Also, be aware of pests and diseases when planting green onions. Do a good job of preventing pests and diseases.
