Do large greens need to be transplanted with seedlings? Why?

Big greens is a general term for some fast-growing leafy vegetables by farmers and consumers, including many small greens such as April slow, May slow, Shanghai greens, and chicken hairy vegetables.

Mustard greens, bok choy, spinach, lettuce.

Now take Shanghai green as an example to talk about whether large green vegetables need to be transplanted with seedlings.

The vast majority of large green vegetables are fast-growing vegetables, seedlings can be harvested in 20-30 days, if the seedlings are not transplanted, the seedlings will appear in different sizes, the main reason is that the seed fullness is different, the sowing depth is different, the soil moisture of the plot is different, and the environment receives sunlight.

There will be some differences in irradiation time, soil depth and soil quality, taking the way of collecting large seedlings and leaving small seedlings for live broadcast and uninterrupted harvesting, which will cause the absorption of nutrients caused by the large group and the competition for sunlight to grow seedlings, and will also induce pests and diseases, and the yield is generally only about 1000 kg. Farmers' reluctance to take time to seedlings is the main reason for the low yield.

Experienced growers generally adopt the method of seedling transplanting, which can save a lot of arable land, and also facilitate water and fertilizer management, which is conducive to the formation of strong seedlings. When the seedlings grow to 3 leaves and 1 heart, water once, and then select large seedlings for transplanting, generally keep the row spacing of 30 cm, the plant spacing is about 20 cm, a single plant can grow to kilograms in about 30 days, and the yield per mu can reach more than 2500 kg, economic benefits.

Greatly improved. In the seedling ground, you can pull out the large edible or continue to transplant, you can also reasonable seedlings, the plant row spacing is about 15-20 cm, wait until the seedlings affect each other and then intersect the seedlings, keep the plant row spacing at 20-30 cm, and finally harvest uniformly, you can also get a higher yield.

Overwintering greens can be transplanted in early spring when the seedlings begin to turn green, and harvested before sprouting.

In summary, large greens can be transplanted, and the maximum economic benefits can be obtained after transplanting, and it can also be used for rooftops, flower beds and flower pot transplanting. In the high temperature stage, appropriate shading measures need to be taken, and in winter, plastic film cover and small arch canopies can be used to increase the ground temperature and air temperature, which is conducive to smooth wintering or eating young vegetables in the cold season.

Seedling transplanting is required. Because in this way, the yield can be increased, and at the same time, the growth rate of large greens will be increased, and the soil will become more fertile.

Of course it does. Because the vegetables grown in this way are very delicious, and the yield is particularly high, and the lodging resistance is very strong.

This kind of vegetable also needs to be transplanted with seedlings, because it needs to be planted in a greenhouse in the early stage, and then it needs to be expanded, so it needs to be transplanted.

Green vegetable seedlings can be transplanted when the leaves of the seedlings grow to 3-4 pieces, generally carried out about 30 days after sowing, before transplanting, it is necessary to carry out land preparation and fertilization, improve the fertility and porosity of the plot, which is conducive to the survival of the seedlings, and then carefully dig out the seedlings from the soil and plant them into the new plot, taking care not to damage their root system, and the roots should have soil masses.

Green cabbage seedlings can be transplanted when the leaves of the seedlings grow to 3-4 pieces, generally about 30 days after sowing, before transplanting, the land needs to be fertilized to improve the fertility and porosity of the plot, which is conducive to the survival of the seedlings.

When transplanting green vegetable seedlings, first carefully dig out the seedlings from the soil, pay attention not to damage their root system, and the roots should have soil mass, which helps the seedlings quickly adapt to the environment and restore their growth.

The root distribution of green vegetable seedlings is shallow, the absorption performance is weak, and there can be no shortage of water within 3-5 days after transplanting, and it is necessary to supplement 1 thin manure water every 3-4 days to promote the seedlings to take root and survive.

Green cabbage seedlings often suffer from viral diseases, after the onset of the plant, the heart leaves of the plant will appear translucent vein-like, the leaves are wrinkled and uneven, and the later stage becomes hard and brittle, and the diseased plant is dwarfed and stops growing, at this time, the diseased plant should be uprooted, and 20% virus net 400-600 times liquid should be sprayed to the field.

Sow. How to grow greens.

To grow greens, you should start by sowing the seeds, soak them in warm water for a day before sowing, and then plant them evenly in the ground. Soaking can help green cabbage seeds germinate and improve the germination rate. When planting, it should be noted that only a thin layer of soil should be used to bury the seeds, otherwise it will be difficult to burrow out of the soil after the seeds germinate.

2. Seedlings. How to grow greens.

When raising seedlings, it is necessary to select seedlings with good growth for planting, choose soil rich in nutrients, and carefully dig out the seedlings to prevent damage to the roots and affect the growth of seedlings. When planting, pay attention to the interval between each seedling, and the planting should not be too dense to avoid the seedlings not absorbing sufficient nutrients.

3. Fertilization. In the process of growing greens, they need enough nutrients to grow healthily, so when planting greens, proper fertilization is required, and the fertilizer is mainly nitrogen fertilizer, and potassium fertilizer and phosphorus fertilizer can also be added. However, it should be noted that the amount of fertilizer applied each time should not be too much, and it is best to increase the number of fertilizer applications and use a small amount of fertilizer each time.

4. Watering. How to grow greens.

When growing greens, they need a lot of water, and they can be watered once a day when the temperature is moderate, and if the temperature is too high, they need to be watered once a day in the morning and evening. If you are using tap water, you need to leave the tap water for one day before watering.

1. Sowing: Soak the full green vegetable seeds in warm water to promote germination, and then sow them in fertile and loose soil. 2. Transplanting:

After the seedlings grow, they are dug up and transplanted in a sunny field. 3. Fertilization: After transplanting, nitrogen fertilizer is provided for green vegetables to promote growth.

4. Watering: Watering once a day to keep the environment moist.

In the process of transplanting greens, it is necessary to pay attention to whether the soil can meet the growth needs of greens, and greens need a lot of fertilizer and water to grow, and should be watered in a timely manner during the growth period to keep the soil moist. During the growth period, it is necessary to pay attention to the prevention and control of pests and diseases, spray insecticides regularly, and if there are fewer pests, they can be removed manually.

1. Soil

The root system of green vegetables is more developed, growing rapidly, the soil for planting green tea is best rich in organic matter, humus with good structure, in the planting process, you can also add some plant ash appropriately, adjust the acid-base ratio of the soil, so that the green vegetables grow better.

2. Moisture

In the process of green vegetable growth, the water demand is different in different periods, the soil moisture needs to reach 65% when the green vegetables germinate, and the water demand increases at the flowering stage, which is more than 75%.

3. Temperature

Greens are hardy and their seeds can germinate in 3 to 5 degrees Celsius and bloom deliberately in 14 to 18 degrees Celsius. If the temperature difference between day and night is large, the flowering and fruiting of green vegetables will be smoother.

4. Pest control

The environmental humidity of planting vegetables is large, which is suitable for the reproduction and growth of some pests, so in the planting process of vegetables, we should pay attention to the prevention and control of pests and diseases, spray some insecticidal and bactericidal agents in advance for prevention and control, and if pests are found, they can be removed manually when the number is small.

Transplanting Chinese cabbage should be done in August-September at the latest.

The latest planting time of cabbage is in August and September of each year, if the cabbage is planted later, it will make the seedlings be frostbitten by low temperature in winter, when planting cabbage, it is necessary to regularly pull out the weeds in the soil, so that the plant grows healthy, when the cabbage grows 8 true leaves, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer to it, so that the yield of cabbage increases.

Cabbage planting

1. Planting time

In the cold regions of the north, the latest planting time of cabbage is in late August every year, otherwise the ambient temperature is too low, which will make the cabbage germinate failure, while in the warm areas of the south, the latest planting time of cabbage is in September every year.

2.Pull out weeds

Before planting cabbage, you need to plough the soil again, remove weeds and gravel in the soil, make the soil loose and breathable, and when maintaining cabbage in the later stage, you need to regularly observe the growth state of the plant.

3. Add fertilizer

Cabbage in different growth stages of nutrient demand is different, when breeding cabbage, need to grow 8 true leaves when the plant, to be a top dressing, you can use nitrogen, phosphorus and potassium compound fertilizer to promote the vigorous growth of cabbage, and cabbage harvest 20 days before the harvest period, can not be fertilized, to avoid poor plant growth.

4. Prevention and control of pests and diseases

Cabbage is easy to be eroded by aphids and whiteflies and other pests in the growth process, this pest will eat the leaves of cabbage, so that the plant rots and dies, and it is necessary to remove and throw away the seriously infected cabbage, and then spray 1-2 fungicides every other week, and also release the natural enemy of the pest, parasitic wasps, for biological control.

Can <> Chinese cabbage be transplanted? How to transplant with a high survival rate? Chinese cabbage can be transplanted, but it's better not to transplant it!

In our northeast, when planting Chinese cabbage, are planted in the pit, when planting cabbage, it is better to sprinkle two more cabbage seeds, two more cabbage seedlings, and when the cabbage can be planted between the seedlings, the cabbage is very delicious, in our place, such cabbage can be eaten as a vegetable, can be made into soup and drunk, and can also be eaten with shallots and cabbage dipped in sauce! However, sometimes, even if you plant cabbage, sprinkle two more cabbage seeds, may not produce all the seedlings, at this time, you have to move the seedlings, and the seedlings after the cabbage, although the survival rate is very high, even if you manage it well, you have to slow down the seedlings for a few days, although when the cabbage is harvested after autumn, the transplanted cabbage will also be wrapped in the heart, and it will grow very well!

However, to transplant cabbage, it is labor-intensive and time-consuming, if the cabbage seedlings are not good, there are too many broken seedlings, and the area of replanting is too large, it will be a very bad, very troublesome work, if you can't make up the seedlings, in the autumn, the cabbage will not get a full harvest! Although Chinese cabbage can be transplanted, the survival rate after transplanting can also be guaranteed, but it is not suitable for large-scale transplanting, and it can only be a small fight to transplant well, large-scale transplanting of Chinese cabbage, early transplanting can be quickly slowed down by seedlings, and late transplanting of Chinese cabbage, when the seedlings come, it will affect the normal production cycle of Chinese cabbage, and if it affects the production cycle of Chinese cabbage, it will also affect the harvest of Chinese cabbage after autumn!

Chinese cabbage transplanting, if planted well, slow seedling time is short, early survival, fast growth, and large growth. If it is not planted well, the seedling will be slow for a long time, and it will grow late, and it will grow slowly and grow small. But sooner or later, fast and slow will survive.

What you should ask about is not the survival rate of Chinese cabbage, but the method of slowing down the survival of seedlings as soon as possible, growing up as soon as possible and growing neatly. Therefore, in our northeast, when planting Chinese cabbage, we would rather waste two more cabbage seeds to ensure the emergence rate of cabbage, rather than transplant!

It can be transplanted, and the survival rate is also high. However, during the transplanting process, it is necessary to protect the root system of Chinese cabbage, ensure the nutrition and air permeability of the new soil, and carefully maintain it in the first few days of transplanting to make the Chinese cabbage adapt to the new soil.

Chinese cabbage can also be transplanted, and it needs to be watered after transplanting, and the survival rate is quite high, so you can try this method.

I think it is possible to transplant and spray 1,500 times the rooting solution after transplanting, which will improve the survival rate.

I agree with the owner's point of view, in addition, transplanting can reasonably adjust the density and uniformity of the plant, can greatly improve the yield, in addition to a more esoteric theoretical basis is that after transplanting, the capillary heel is damaged, can open the secondary metabolism of crops, this is what I heard from a professor of the Chinese Academy of Agricultural Sciences to know, he is the first in China to propose secondary metabolism View original post

The benefits of transplanting can be roughly from the following aspects: **First, after transplantation, the root system of green vegetables is damaged, the growth of green vegetables is slowed down, and more nutrients are accumulated, which is conducive to improving the flavor, and second, after the early stage of slowing down the accumulation of nutrients, it will not grow wildly, and it can produce more in the critical period, and third, reasonable dense planting is conducive to improving the overall yield View the original post

After transplanting, the small greens grow very well, but some of the root damage will die because of this, so each transplanting is particularly tangled. View the original post
