When transplanting green onions, cut off the top half, will this affect the growth of green onions?

The leaves of green onions are hollow, tubular, and have mucus in them, which some people call shallot snot. The leaves of green onions are composed of a leaf body and a leaf sheath, the leaf body is a green wave leaf, and the leaf sheath is attached to the green wave leaf. We are also called Papi.

In fact, it is the tissue that makes up the stalk of green onions. Leaf sheaths, garlic, ginger, etc. are the same. The wavy stem is actually not a stem in the real sense, but a false stem, and the green onion is what the green onion leaf looks like.

The green leaf body is photosynthesis.

The nutrients produced are stored and transported to the base part of the green onion through the leaf sheath, which plays a role in promoting the stem thickness of the green onion and increasing the yield. The growth of green onion stems is affected by the leaf emergence rate, the number of leaves, and the leaf area. Usually the higher the number of leaves, the thicker the plantain becomes.

The longer the leaves, the thicker the leaf sheath and the thicker the plantain. The length of the stalk of the green onion is buried in the leaf sheath by continuous soil drainage, so that the leaf sheath continues to extend upward, which also gradually increases the length of the plantain.

This is where green onion leaves come in. Doesn't cutting off a portion reduce the leaf area of green onions? Reducing nutrient accumulation is not conducive to the survival of seedlings. Some people might say, cut off part of the broken leaves.

It can reduce the evaporation of water. That's simply wrong. The large leaf is a very dry crop, and there is a saying that "drought does not die wave".

Because the leaves of green onions are smooth on the outside, with the addition of white wax, the evaporation of water can be greatly reduced. Isn't it faster to cut off a part of the wavy leaves that will destroy the tubular tightness of the green onion, thus opening the holes? Then, the green onions with the dead leaves cut off look neat, and then moved to a warm greenhouse, and the green onion leaves will grow and can be dragged to the market to sell.

Still good. A pound of green onions can reach about yuan. This is my family's ** from last year.

It is nearly 1 won higher than the green onions harvested in the normal season. All the green onions in our village are transplanted for the second time after cutting off the dried leaves above Pa white, and they are transplanted and planted from mid-November, from the beginning of the month to the middle and late part of the month, which is the time of the Spring Festival, and the ** of green onions is the highest of the year. So my side is the dried onion leaves cut during the second transplantation in the restaurant in winter, and they are cut directly from the white of the green onion, which has no effect, and directly accelerates the growth rate of the germination of green onions after transplantation.

In less than half a month, the newly transplanted green onions can be sold during the Chinese New Year. Why not be happy?

Under the transplantation of green onions at a normal time, I don't do anything here, as long as some of the branches and leaves do not disappear, we will pick them, and transplantation in winter is the most classic way to cut branches and leaves. Green onions are tenacious and resistant to drought, and there is no problem at all with overwintering growth. The green onions on the hillside on Chinese New Year's Eve were frozen white and frozen with popsicles.

As long as you dig it out, you can directly cut the dead leaves, move them to the vegetable greenhouse and water them once, and you can live for three or three days.

There is no impact. The vitality of green onions is tenacious, when transplanting, the upper half of the green onion leaves is subtracted, and the growth rate of green onions is accelerated.

It will not be affected, there is no problem if the roots are not damaged, and they can continue to grow in the later stage.

Transplanting green onions and cutting off the top half of the green onion leaves has no effect on the green onions, and the survival rate is still very high. Because if there are too many leaves at the beginning of transplanting, too much water will be dissipated from the leaves, and the roots of the green onions at this time cannot quickly absorb water from the ground, so that the newly transplanted green onions are easy to dehydrate and die.

1. When harvesting green onions, if only the leaves of the green onions are cut, then the green onions can be followedThe laws of natureIt can still grow very vigorously while it is growing.

We can compare the greens around us as an example, such as pea tips.

This is the case, if you cut off the entire rhizome of the pea tip, then the pea tip will never grow again. If you just pinch off his delicate leaves, he can still grow dense parts. It's as if the rhizome is his life, and the leaves are just creatures that he reproduces, and as long as the rhizome is intact, he can continue to cultivate new life.

Second, when harvesting green onions, if the white part of the green onion is completely cut off, then it is definitely impossible for the green onion to grow again.

When we plant green onions, we also need to understand the growth environment of green onions, under normal circumstances, green onions will be planted in large quantities in the north, because they have a higher demand for green onions. Green onions are more suitable for planting in spring and autumn, because they prefer a mild environment, but they are not tolerant to high temperatures, so planting them in summer is definitely a very wrong decision. And it is necessary to ensure sufficient light and water to be able to grow very high-quality green onions.

3. Green onions are generally harvested together with green onions and leaves, and are rarely harvested separately, and many farmers will choose to harvest together in order to avoid green onions rotting in the soil, so there will be no such problems.

When we harvest green onions, we should also pay great attention to the fact that the leaves of green onions are actually very fragile and easy to break if we are not careful. Therefore, we should pay special attention to the harvesting time, if the harvest is carried out when the weather is cold, do not harvest it in the morning or late in the evening, so as not to cause the harvested green onions to be frostbitten, so that the quality and quality of the green onions will be worse, and there will definitely be ** differences in sales. And when we harvest the green onions, we first have to clean up the withered leaves, then get rid of the basic soil, and finally put the green onions in the rice field to dry for half a day, and then use a rope to tie them up and store them.

Chief, cut the leaves and green onions, the longer the better, as long as we don't cut the roots, the leaves will grow again.

OK. When harvesting green onions, if only the green onions and green onion leaves are harvested, then the green onions can grow again. If the white part of the green onion is cut at the time of harvesting, the green onion will not be able to grow anymore after it is cut.

Generally speaking, green onions will be uprooted and harvested once, and only shallots will harvest the green onion leaves for secondary growth.

Of course, it can grow again, because I have experimented, but the growth of green onions that grow later will be very weak.

Green onions can't grow anymore after being cut, and green onions are different from leeks, they don't have a rebuilding function, and they will die after being cut.

I've never seen the green onions sold for sale without roots, even the chives are all rooted. Green onions without roots are not easy to preserve. Whether it is winter onions or shallots, none of the various varieties including green onions can be cut and stubble, and it is not a vegetable like leeksIt will definitely grow, so I'm going to combine it with the green onions grown in my hometown in rural Gansu.

Note that the time to cut green onions is in the eleventh month of the lunar calendar, and when you cut green onions, you just cut off the leaves, not to cut them, but to pluck the dried leaves by hand to filter them out and pull them out.

We don't cut the green onions here, but we have seen the shallots sold cut, if you cut it should be fine, it has roots and will continue to grow taller, but the appearance of growing is definitely not as good as the stubble! I don't think it's better to cut it, I generally don't buy cut onions for hydroponic growth: find a transparent glass container, higher than 5 cm in height.

Place the shallots root side down, or a few more if the container is larger. Then add water to it, and the water can be submerged in the green onion. Don't add too much, otherwise it will inhibit its growth.

When cutting the shallots, cut off the leaves and keep the shallots to regenerate. The length should be about 5 cm, with 3 cm for the green part. Place the shallots in a clear glass container and add a little water, making sure to submerge its roots.

After that, put it on the sunny windowsill for daily maintenance: in order to promote the growth of green onions, it is necessary to provide a suitable environment. Place it on a sunny windowsill to provide plenty of light for at least 4 hours a day.

You can also open the window for ventilation, which is conducive to cooling.

Harvesting green onion leaves: Generally, after 1-2 weeks, the green onion leaves will be ready to grow, and then they can be cut. The growth of green onion leaves consumes the nutrients in the bulb, and it will not grow again after three harvests, and it can be replaced with new onion root culture.

This is a special variety of green onions, commonly known as perennial green onions, the scientific name of German all-green chives, German all-green chives plant erection, plant height 45-50 cm, slender leaves, dark green leaf color, tubular leaf diameter of 3 5 mm, strong tillering force.

It's going to be long. Because the roots of green onions are still underground, they will always grow if they have roots, so you don't have to worry about yield.

It can be longer, the growth cycle of green onions is very short, it can be cut and long, and several stubbles can be harvested a year.

It must continue to grow, as long as you don't pull out the roots of the green onions, the green onions can continue to grow.

The time selection of green onion transplanting should be determined according to the listing plan, and the appropriate transplanting time should be selected according to the green onion growth cycle.

The green onion is full of stubble in the main producing areas of various kinds of green onions, which is in line with the planting rules of most green onion friends in China.

Seedlings in the current year, transplanting in the same year, and listing in the same year, this kind of stubble can be planted and transplanted in May and July;

Seedlings are raised in the current year, transplanted in the current year, listed in the following year, and can be planted and transplanted in August, September, November and December;

Seedlings are raised in the current year, transplanted in the next year, and marketed in the next year, in this case, they need to be planted and transplanted in April and May of the second year.

Mechanical transplanting.

Green onions can be planted all year round, choose to plant in early spring in spring, water once in the morning and evening, and sprinkle some nitrogen fertilizer after watering; The summer planting time is between June and July, and pay attention to shade when planting; In autumn, plant around October, pay attention to the humidity of the plant growth environment; In winter, it is generally planted in early December, and attention should be paid to cold-proof treatment.

1. Spring planting. Green onion is a common vegetable in life, its unique taste is loved by the public, so when is the most suitable green onion planting, green onion can choose to sow in early spring, planted in the soil that has been thawed, and watered once a day in the morning and evening, sprinkled with nitrogen fertilizer after watering, so that the green onion can grow faster.

2. Summer planting. Green onions are drought-tolerant and cold-resistant plants, generally planted between June and July, do not need too much watering to grow, but in the summer planting to do a good job of shading measures, when the sun is strongly exposed, it will cause the yield of green onions to decrease, wait for the sun to go down after watering once a day, and then use diluted nitrogen fertilizer on the soil.

3. Autumn planting. Autumn planting is generally carried out around October, autumn belongs to the rainy season, rainy and continuous, the air humidity is very high, you can choose to water once every three days, fertilize once a week, when the rainy season comes, do a good job of drainage, water every day according to soil moisture, to avoid rainwater for a long time to soak the plant and cause root rot.

4. Winter planting. The planting time of winter planting is generally selected in early December, planting green onions in winter to do a good job of cold resistance measures, fertilizing once every half a month, watering according to soil moisture as appropriate, applying a certain amount of potassium fertilizer every day, which is more conducive to the growth of green onions, when the snow comes, you can cover the soil with film, avoid the plant being frostbitten, and let it survive the winter.

Green onion transplanting can generally be done all year round, and it is generally better to transplant in May and August.

The suitable temperature for the growth of green onions is 12-20 per month, with strong cold tolerance and poor heat resistance, vigorous growth in autumn and slow growth in summer, and poor quality.

The general transplanting words are shallots, there is no transplanting of shallots, because shallots seedlings can grow, after growing up is green onions, now is the season of transplanting shallots, remember to dig the ditch deep when transplanting, and wait for the green onions to grow up after the roots of the green onions to cultivate the soil, and then the green onions grow up and then cultivate the soil, repeat several times, the higher the soil, the longer the green onions.

Shallots. The leaves are hollow, cylindrical, and have some mucus in them, which some people call brand figuratively called onion runny nose.

The leaf surface of the shallot is composed of the leaf body and the petiole, the leaf body is the green onion leaf, and the petiole is the continuous under the green onion leaf, which is also called the green onion skin, which is actually the mechanism that constitutes the shallot stalk, which is the petile, garlic, and ginger.

The stalk is not actually a stem in the real sense, but a false stem, which is formed by the petiole of the shallot.

This is what the leaf surface of the shallots looks like, and its effect is that the emerald green leaves are stored and transported to the cornerstone of the shallots according to the petioles according to the nutrients produced by the plant's photosynthesis, which in turn promotes the thickness of the shallot stalks and increases the production volume. The growth and development of shallots are affected by leaf velocity, leaf number and leaf area index.

harmed. Generally, the larger the number of leaves, the thicker and higher the green onion stalks. The stronger the foliar growth, the more hypertrophic the petiole and the thicker the stalks.

The length of the shallot stalk is based on the continuous loosening of the soil, and the petiole is buried to promote the petiole to continue to widen, which gradually increases the length of the scallion stalk. This is the effect of shallots.

If you cut a part of it, won't it make the leaf area index of the shallots smaller? It will cause the accumulation of nutrients to be reduced, which is not conducive to the planting of young plants and cut off the upper half of the green onion leaves, leaving the half of the green onion leaves close to the leaf tips, the total area of the small green onion leaves is small and next to the road surface, of course, the temperature is less harmful to the sun, the leaves become lighter, the normal watering of the moist soil layer, the leaves are not loose, but it is firm, and when they are planted, we cover the soil layer very high, bury the leaf tips, the leaf tips can be a good maintenance of the encapsulated heart leaves, accompanied by the slow root shallots. The small onion leaves can still grow and develop, and the heart leaves also grow quickly. The chives grown at home are usually eaten by picking leaves, but since it was not clear that it was shallots at that time, they also picked the leaves and ate them together, which <>

The green onion that has been picked is the same as the chives, and a small amount of liquid will flow on the broken surface of the green onion leaves, which is conducive to the broken surface of the green onion to get better on its own, and the broken surface of the green onion leaves must be better for a certain period of time.

Pull out the seedlings and go out to get rid of the leaves and transplant them, pay attention to the watering close to the soil layer after transplanting, and do not have to get to the large lush leaf fracture surface; In addition, you can also do this is that you are ready to plant at dusk, then in the morning you cut off the top half of the big lush leaves, and by dusk the green leaves will become relatively good by themselves, pull out the seedlings to get some soil or water a few drops of water to the big lush green leaves break the surface of the fine; Homestay saladIn the springThe planting is to pick the green onion leaves to eat, and then plant at dusk. Of course, you can sprinkle some after cutting off the top half of the large lush leavesGrass and wood ashFade the scar, similar to the solution that everyone usually solves after leek cutting, so that after planting shallots, you don't have to worry about watering or rain to harm the broken surface of lush leaves.
