Leek transplanting time, when is the old leek transplanted?

Leeks are usually transplanted between late July and early August in summer. When transplanting, a single row of deep furrow planting method is adopted, the seedling pond is watered thoroughly before planting, the leek seedlings are cut off, the tip of the fibrous root is left 2-3 cm, and the leaves are cut off 2 3 to reduce foliar evaporation. According to the row spacing 40 cm ditch, the depth of the ditch is about 15 cm, in the ditch according to the plant spacing centimeter seedlings, watering, covering the soil, planting soil depth to not bury the leaf node is appropriate, after the soil cultivation leek ditch is slightly lower than the row between 4-6 cm, in order to facilitate the soil cultivation year by year to achieve high yield.

After transplanting leeks, water them twice in a row, loosen the soil in time to squat the seedlings, and keep the soil dry and wet in the future. When the leeks grow to 15 cm high, 10 kg of diammonium phosphate per mu is applied in combination with watering, and then topdressing is done again at an interval of 20 days. After the beginning of autumn, the weather is cooler, so it is necessary to control the water in a timely manner, and pour enough winter water before the soil is frozen.

If you find that there are leeks sprouted, it is advisable to remove them in time the next morning. September is the most suitable growing season for leeks. After entering this period, it should be watered once every 7 10 days, combined with watering and topdressing fast-acting nitrogen fertilizer 3 times, and topdressing 10 15 kg of urea per mu each time.

After mid-October, there will be no top dressing, and watering should be done on the ground. After transplanting and planting, the leeks are not harvested that year, and the roots are mainly strengthened. After winter, the shed is used to produce green leeks, or cover and cultivate leeks.

Transplanting should be carried out from late July to mid-August, and should be completed before the Mid-Autumn Festival, if the leeks grow very thin and short, they can be transplanted in the early spring of the following year. Old leeks generally use the method of deep ditch transplanting, pay attention to seedling and planting density, and should also repair furrow drainage and irrigation to do a good job in field management.

Transplanting method of old leeks

1. Deep ditch transplanting.

When transplanting old leeks, a single row of deep ditch transplanting is generally used, furrow planting can be as the plant grows, continue to cultivate the soil, turn the rows into deep ditches, water the soil thoroughly before planting, water as much as possible, and then dig out the leeks, remove the roots at the front end, leaving 2-3 cm long roots, and two-thirds of the leaves should be cut off. Dig a deep trench with a row spacing of 40 cm and a depth of 15 cm, and plant seedlings at a distance of centimeters from each plant.

2. Seedling raising and planting.

Seedlings should be raised 3 days before planting, and a small amount of water should be watered before seedlings to prevent root damage and remove the emaciated seedlings in the leek seedlings. The number of seedlings should be planted on the same day, and if they are not planted on the same day, they must be planted within the next day.

The planting density of leeks should be reasonably densely planted, if the density is too small, it will affect the yield, and if the density is too large, it will affect the quality. If the tillering force is weak and the plant is erect, it can be planted densely.

3. Repair furrow drainage and irrigation.

Transplanting leeks should pay attention to the soil to choose the soil that is easy to drain and irrigate, because leeks are afraid of flooding, and deep ploughing should be carried out before planting, which can make the soil soft, and then hug the ground to build a furrow ridge. If the cultivation area is in the south, it is necessary to carry out high wa cultivation due to too much rain. If it is in a place with less rain in the north, it is suitable for flat furrow cultivation.

The method of flat furrow cultivation is 2-3 plants per bush, generally with a row spacing of 25-30 cm and a bush spacing of 7-10 cm.

4. Field management.

When burying the soil, the depth of the soil should not bury the lobulated nodes. After planting, it should be watered 2 times in a row, and the soil should be dredged in time, when the leeks grow to 15 cm tall, they should be topdressed once, and then topdressed again after 20 days. Watering should be controlled after the beginning of autumn, and in winter, attention should be paid to watering before freezing.

Leeks have high requirements for fertilizer, should use sufficient nitrogen, phosphorus fertilizer, planting should also use enough organic base fertilizer, after using up organic fertilizer, remember to turn over the soil, fertilizer and soil mixed evenly, if not the use of manure, but straw compost, can be supplemented with diammonium phosphate.

The transplanting time of leeks should be determined according to the growth of leeks and the planting time of leeks. Generally, if it is a leek planted in March or April in spring, when the leek grows to about 18 cm, the leek leaves have four to five leaves, the growth is relatively vigorous, and the roots are relatively strong, and then it can be transplanted.

The transplanting time of leeks is generally selected from July to August every year, because the weather conditions during this time are more suitable, and moisture, humidity and weather temperature can help leeks quickly adapt to the new cultivation environment after transplanting, and reduce the yield decline caused by improper transplanting. Leeks are plants that are more afraid of waterlogging, so in the transplanting process, it is best to choose soil varieties with deep soil and drainage and irrigation. If the soil is sticky, or the soil is not very clean, there are traces of pests and diseases, then it needs to be used after washing in the autumn equinox, the weather will turn cooler, and the growth potential of the leeks will also be reduced, this is the best time to transplant leeks.

After the autumnal equinox, there will be a period when the average daily temperature is around 20 degrees Celsius.

The average temperature is between 15 and 16 degrees Celsius for 20 days, and the average temperature is around 10 degrees Celsius for at least 30 days. The leaf clumps of leeks can withstand low temperatures of minus 4 6 degrees, and when the temperature drops to minus 5 6 degrees, the leaves can die, because the underground roots have a higher sugar content and can withstand low temperatures of about minus 30 degrees. The optimal temperature for the growth of leek roots is 15 18.

Since then, after transplanting leeks, there is enough mild time to grow new roots, and before fertilization and watering management, new roots can reach 4 6 roots, and the onset of spring does not affect the yield.

The best time for transplantation should be from late July to mid-August. Leeks are low-temperature vegetables, which can be planted after thawing on land until the autumn equinox, and are generally best planted in mid-March and late May. If you miss the best time to plant in the spring, you can sow in the summer, but the earlier the better.

When planting, choose a place where the light is not too strong. After planting, water it in time to make it more conducive to the survival of leeks.

The best time for vegetable transplanting is July to August every year, because the temperature is high in July and August, the humidity is high, the leek not only grows rapidly in the aboveground part in such an environment, but also the root system grows rapidly, the leek root system is pruned before transplanting the leek, after the leek transplanting, the leek root system can recover the growth in a short time, so the most suitable month of July and August every year is to transplant the leek.

So how do you transplant leeks? Therefore, when transplanting leeks, we should choose leeks with a life span of 1-2 years, the growth of leeks after transplanting is long, and the planting income is high, in addition, the leeks with a life span of 1-2 years grow rapidly, which can improve the transplanting survival rate of leeks.

Before transplanting leeks, they should be watered thoroughly, and then after digging the leeks out of the ground, the hairy roots of the leeks should be cut off first, and the leaves of the leeks should be cut off at the waist, leaving only all the leek stems and 3-4 cm leek leaves. After cutting the leeks, you can transplant the leeks, the leeks can be transplanted in the hole or in the row, if it is a hole planting, 5-6 leeks are planted into a hole, and the distance between the holes should be kept 10 cm, so as to facilitate better ventilation of the leeks. If it is planted in rows, place the leeks in turn in the dug rows, and pour enough transplanting water after planting.

The purpose of pruning the leek root system when transplanting leeks is because the leek root system will grow with the growth of leeks, if the leek root system grows too much, it will affect the leek root system to absorb nutrients and water in the soil, and the leek root system will be properly pruned, and the leek root system has sufficient space, which can better absorb nutrients and water in the soil, and lay a solid foundation for the vigorous growth of leeks.

Pruning leek leaves is to prevent the water evaporation of leek stems and leaves, the time of leek transplanting is exactly the hottest time of the year, if you do not prune the leek leaves, the evaporation of water of leek leaves under the irradiation of sunlight is greater than the speed of leek root system to absorb water in the soil, which is not conducive to the survival rate of leek transplanting. Proper pruning of leek leaves can reduce the evaporation of water in the leaves and improve the transplanting survival rate of leeks.

When the leeks are transplanted and grow new leaves, do not harvest the leeks before the leeks overwinter, because stopping the harvest of leeks can make the nutrients of the leeks leaves transported to the root system, which is conducive to the nutrient accumulation of the root system of the leeks, avoid frostbite of the leeks during the winter, and also lay the foundation for the growth of the leeks in the second year.

Leeks are always the best in the spring. When transplanting leeks, you must first ensure the temperature and humidity of the transplantation, and then dig a pit directly, put the leeks in the pit, and water them after burying them.

Leeks are best transplanted during the summer months. The leek seedlings can be placed directly in the soil that needs to be transplanted, and then buried with the soil, and then watered with some water.

I think transplanting in April and May is the best. Dig a pit in the transplanted land, place the leeks in the pit, and finally cover it with soil.

When is the best time to transplant leeks? How to transplant leeks?

Now it is best to plant leeks in the second month of the lunar calendar, as long as the leaves on the ground are cut off, and its head and roots are retained, it can be transplanted directly.

Leeks are most suitable for transplanting in July-August.

The best time for leek transplanting is July to August every year, because the temperature is high in July and August, the humidity is high, the leek not only grows rapidly in the aboveground part in such an environment, the root system also grows rapidly, the leek root system is pruned before transplanting the leek, after the leek transplanting, the leek root system can recover the growth in a short time, so the most suitable month for transplanting the leek in July and August every year.

Leek transplanting needs to pay attention

1. Reasonable dense planting

The density of transplanted leeks must be reasonable, if it is too large, it will cause poor ventilation in the field, and leeks are prone to diseases, especially downy mildew, which will also lead to less tillers of leeks and shorten the planting years. The density is low, and although the leeks grow strong, the yield is also low. Leeks in the northern region are mostly planted with furrows, with a row spacing of 15-20cm, a hole spacing of 10-15cm, and 6-8 plants per hole.

2. Treatment of leek roots

Before transplanting, take out the leek roots, if the fibrous roots are too long, you need to cut off some fibrous roots, leaving 3-5cm long, so that when placed in the planting furrow, the root system can have enough space to stretch and be conducive to growth. If the seedling is too large, it is necessary to cut off a section of the leaf, leaving about 10cm, so that after planting, the leaf water transpiration can be reduced before the root system recovers the absorption function, which can better slow down the seedling.

3. Key points of transplanting

When transplanting leek roots, it is more appropriate to plant at a depth that does not bury the leaf sheath, and it will be easier to survive if it is flooded with water after planting. After three or five days of slow seedling, loosen the soil again to promote root growth.

Leeks are best transplanted in spring from February to May and autumn from August to October.

Because the ambient temperature in these two periods is just right, it is like changing the pot of flowers at home, and spring and autumn are the best transplanting seasons, which is conducive to the rapid development of the root system and the rapid growth of seedlings. If you are not in a hurry, it is best to transplant the tree in the spring when it sprouts, which is more conducive to rooting and growing on it.

The root system of leeks is replaced by new and old, it is not like other vegetables, it can be transplanted directly, leeks should be pruned before transplanting roots and leaves, only some old roots are pruned off, it is conducive to the germination of new roots, just like the above **, after pruning the root system, it is necessary to remove too many leaves to a part.

Because the leaves are too long will consume a lot of water, the leaves will wilt after transplanting, which is not conducive to its slow seedlings.

Because leeks are different from other vegetables, after digging out of the ground, they should be dried roots, and dried roots are also called cool roots, which is conducive to the germination of new roots.

Leeks are suitable for transplanting from late June to early July. Select plots with fertile soil and convenient drainage and irrigation, apply 4-5 cubic meters of rotting farmhouse fertilizer per mu, and level the furrows. The width of the furrow is 2-3m, every 3 furrows is a group, and a 1m wide cold-proof zone is set on its north side.

Before transplanting, cut off the ends of the fibrous roots and arrange the bulbs into small handfuls. Flat furrow hole planting, row spacing 13-20cm, hole spacing 10-15cm, 6-8 plants per hole is appropriate. When planting, it is advisable not to bury the leaf sheath, and after planting, it is practical and watered in time.
