When is it better to transplant leek roots

The planting method is as follows:

1. Site selection. 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.

Transplanting from late June to early July. Before planting, cut off the ends of the fibrous roots and arrange the bulbs into small handfuls.

2. Planting. The growth of leek seedlings is slow, so it should be sown early, and it is advisable to sow from late March to late April. After soaking and germination, the wet sowing method is used to sow in the seedling furrow, and the soil is covered twice, the first time is covered with a thin layer of soil, and then the second time after the moisture is returned, and the total thickness of the covering soil is 2cm.

The amount of seed per mu is 6-8kg. After covering the soil, cover the mulch film to facilitate temperature and moisture preservation, and remove the mulch film after the emergence of seedlings. Generally, 1 acre of seedlings can be planted with 7-9 acres of vegetable fields.

3. Density. Leeks are very reproductive, and basically after they are planted to survive, within a week or so, you will see several new leek seedlings popping up around the hole where there were originally only three leek seedlings. Therefore, when leeks are planted in flat furrows, the row spacing is 13-20cm, the hole spacing is 10-15cm, and 6-8 plants per hole are appropriate.

When planting, it is advisable not to bury the leaf sheath, and after planting, it is practical and watered in time.

4. Fertilization. If you want leeks to grow fast and tender, then fertilization is necessary, but if the fertilization method is not correct, it will also cause the leeks to age, and they cannot be eaten at all. The growth process of leeks is a continuous process, so first of all, we must apply enough base fertilizer, and secondly, about a week after planting, we can mix urea with water to water leeks to promote the growth of leek seedlings.

After each harvest, top dressing is carried out according to the growth of the leeks and the fertility of the soil in the field, and the fertilizer used can be animal manure, human manure and urine water, or urea.

5. Disease prevention. Leek is a perennial root vegetable, there are many pests and diseases, only scientific, safe and reasonable use of pesticides, in order to effectively control the occurrence and harm of pests and diseases. As long as we are careful enough, there will be no pests and diseases, and if they appear, we must spray pesticides in time to prevent and control them.

The most important thing is not to spray pesticides for 15 days before harvesting, which will affect the quality.

6. Harvesting. The number of leeks harvested each year depends on the growth of leeks, fertilization and market**. In winter and spring, the arch shed leeks can be harvested 3 stubbles. Although the autumn quality is good, in order to cultivate roots and lay a material foundation for the growth of arch sheds, it is advisable to harvest L-2 stubble.

Leeks are cut with 7 leaves and 1 heart. Early morning harvest is best. It is advisable to cut 3-4cm yellow leaf sheath on the bulb.

In the future, each knife should be slightly higher than the previous stubble to ensure normal growth. The yield is low in the first 1-2 years after planting, 3-6 years is the peak growth period, the yield is the highest, and it enters the senescence stage after 10 years, so it should be transplanted in time.

Leek roots are generally transplanted in late July to early August (such as leek seedlings grow thin and small can be transplanted in the early spring of the second year), transplanting using a single row of deep furrow planting method, before planting through the seedling pond, the leek seedlings out of the cut off the fibrous root tip to leave 2-3 cm, cut off the leaves 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 planting, water 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 it is not a leek, then when the leek seedlings grow to 4 or 5 leaves and the plant height is 18 to 20 cm, it can be transplanted and planted. Before transplanting, 10,000 kg of soil miscellaneous fertilizer per mu, or 50 kg of superphosphate, plus 10 kg of zinc sulfate, and spray 40% of 800 times of phoxanthion on the fertilizer to prevent root maggots. Then turn the rake deep and level the ground.

After the leeks are seedling, shake off the soil on the roots, and when transplanting, use a shovel to dig a shallow ditch, water, and then place the leeks in turn in the planting ditch. When loading, grasp the plant spacing of about centimeters, and the row spacing of about 30 centimeters. After the planting is completed, the soil is covered shallowly, and the depth of the soil cover is appropriate not to bury the leaf sheath and the leaf body segments, and the excess soil between the rows is buried into the row with the continuous growth of leeks.

It can also be carried in a hole, and when planted in a hole, 15 plants per hole. The thickness of the covering soil should not exceed the leaf sheath as the standard, and it should be watered immediately after planting, and then watered again after 5 days.

I just turned the seeds today, put chicken manure in the bottom fertilizer, and sprinkled grass ash on the surface. View the original post

<> leek root is best transplanted from late June to early July. Leek roots are transplanted when the leek seedlings have grown to 4 to 5 leaves, or when the plant height is about 17 cm. When transplanting leek roots, loose and fertile soil should be selected, and to keep the seedling spacing of 10 cm, it is also necessary to water frequently to keep the soil moist.

From the end of the month to the beginning of July.

<> leek root is best transplanted from late June to early July. The spring of leek root transplanting hall is generally in summer, and it can also be judged by the growth of the plant, when the number of leaves of the plant is 4 to 5 leaves, or when the height of the plant is about 17 cm.

2. Soil conditions.

In order to ensure the survival rate of leek roots after transplanting, fertile and loose soil should be selected when transplanting, and humus soil, farmhouse fertilizer, and mixed preparation need to meet the soil conditions of leek roots, which can provide sufficient nutrients for them, thereby greatly improving the survival rate of leek roots.

3. Interval requirements.

When transplanting leek roots, it is necessary to keep the soil flat, and the way of single-row cultivation should be adopted, and the spacing between the seedlings should be 1 cm, and the row spacing should be kept at 15 cm, so as to ensure that there is a larger growth space between the seedlings, and at the same time, it can also ensure that the seedlings are sufficient to withstand nutrients.

4. Moisture conditions.

When transplanting leek roots, it should be watered in time to promote the combination of its roots and soil, and at the same time, irrigation should be carried out when the new seedlings grow out to ensure the growth of new seedlings.

"Leeks can't grow in winter, they can be transplanted and planted most of the year, so you can choose to transplant them in early spring or autumn, from March to April, or from September to October. ”

Leek planting management:

1. Seed selection.

It is recommended to choose full, no impurities, no insect mouth, cold and insect resistance, heat resistance, and strong tillering varieties.

2. Treat the seeds.

Dry it for one to two days, then put it in water at about 40 degrees for cleaning, soak it for half a day when the water temperature reaches about 30 degrees, and then put it at room temperature for germination, and 85% of the seeds can be sown when they begin to germinate.

3. Soil preparation and fertilization.

The seedbed should be selected for drought watering, waterlogging can drain the high-dry plot, should choose sandy loam soil, and should be deeply turned before sowing. Before sowing, shallow tillage, fine rakeing, and combined with fertilization, leveling and furrowing, furrow height 12-14 cm, furrow width 100-120 cm, base fertilizer must be applied sufficiently.

4. Strengthen field management.

After planting, water twice in a row, hoe 2-3 times in time, the soil is semi-dry and wet, and it should be drained in time in the rainy season. Due to the more rain in summer, therefore, according to the actual moisture, reduce the amount of watering and pay attention to drainage and timely cleaning of yellow leaves and leeks near the ground, reduce the consumption of nutrients, in the whole growth cycle of leeks suitable to apply green water-soluble fertilizer, with a small amount of many times as the principle.

5. Pest control.

The main diseases in the growth period of leeks are leek blight and gray mold, and the main insect pests are leek maggots, thrips, etc., which should be sprayed with pesticides in time according to the needs for control.

6. Harvest at the right time.

When the leek seedlings grow to a height of 25 to 35 cm, they can be harvested. Most of them are harvested in spring and autumn, and it is best to choose to harvest in the early morning on a sunny day, and the harvesting knife edge is about 2 4 cm from the ground.

Leek roots are generally transplanted in late July to early August (if the leek seedlings are thin and small, they can be transplanted in the early spring of the second year).

When transplanting, the single-row deep furrow planting method was adopted, the seedling pond was watered thoroughly before planting, the leek seedlings were cut off from the tip of the fibrous root to leave 2-3 cm, and the leaves were cut off 2 3 to reduce foliar evaporation. According to the row spacing 40 cm ditch, the ditch depth is about 15 centimeters of spring judgment rice, in the ditch according to the plant spacing centimeter seedlings, watering, soil covering, planting soil depth is not buried in the leaf node is appropriate, after the soil leek ditch is slightly lower than the row 4-6 cm, in order to facilitate the soil cultivation year by year to achieve high yield.

After planting, water twice in a row, and loosen the soil in time to squat the seedlings. When the leeks grow to 15 cm high, they are combined with watering and apply 10 kg of diammonium phosphate per mu, and then top dressing 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.

Pest and disease control of leeks

Leek blight harms rhizomes and leaves, especially pseudostems and bulbs. The leaf damage is dark and water-stained lesions, the leaves turn yellow and soft rot, the stems and roots are damaged with brown soft rot, and the diseased part produces sparse white mold when wet. The overwintering of pathogens on soil disease residues is a high temperature and high humidity hazard, with an appropriate temperature of 25-32, and the peak period of the hazard is around August.

In the early stage of the disease, the time of cloudy days, can be sprayed with 50% gray nucleus 1000 times liquid or 40% sclerotia net 2000 times liquid for control, in each stubble of leeks harvested with hail and after the uniform spraying of drugs. When selecting agents, attention should be paid to the selection of new fungicides with high efficiency, low toxicity and low residue, and they should be applied alternately.

The best way to transplant leek roots: the soil should not be heavy, and the terrain should be as low-lying as possible; The best time to plant is in spring and autumn; Eliminate bad roots and retain new roots; cut off the roots and plant shallowly; Appropriate planting spacing, maintaining reasonable plant spacing and row spacing.

1. The soil should not be heavy, and the terrain should be as low-lying as possible

Leeks should not be heavy, many vegetables are actually like this, because long-term growth of leeks, the parasitic bacteria on the roots of leeks will remain in the soil, and there are often a large number of underground pests in the soil, which will erode the new leek roots and affect the growth of leeks. If you choose a higher place, the plot will be higher with the increase of organic fertilizer, so that it is difficult to water it, which will affect the growth and yield when the weather is dry.

2. The best planting time is in spring and autumn

The planting time of leeks is generally not limited, in addition to the winter can not grow, most of the time of the year can be planted, generally we choose the early spring when planting, the advantage of planting at this time is that you can also eat the leeks of the year, the survival rate will be higher, if you choose to plant in autumn, eat leeks can only be next summer.

3. Eliminate inferior roots and retain new roots

Leeks are perennial plants, with the increase of time, leek roots and leaves will increase, generally leek is a new root once a year, the old root continues to grow, but the new root is stronger than the old root. In addition, there are more pests and diseases parasitic on the roots of old leeks, forming diseased roots and mycorrhizae, therefore, we should choose new roots and strong roots when planting, and remove the old roots, so as to ensure the replacement of new and old leek roots and lay the foundation for the robust growth of leeks.

4. Cut off the roots and plant shallowly

After eliminating the old, diseased, and injured roots, it is necessary to cut off a part of the new roots that grow particularly long, and it is generally better to keep 8-10 cm, and then plant the new roots into the ground. At this time, don't plant too deep, let the upper part of the leek root expose a small part of the ground, 1 cm is enough, don't bury all the leek roots in the soil. If planted too deeply, the roots will be bored, and the newly grown leeks will grow slowly.

5. The planting interval is appropriate, and the plant spacing and row spacing are reasonable

When planting, leeks grow vigorously and have a well-developed root system, so a reasonable distance is particularly important. Empirically speaking, it is generally desirable to keep the plant spacing at 15-20 cm and the row spacing at 25-30 cm.

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.
