What season is the best time 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.

When it comes to leeks, I think of leek buns, dumplings, leek scrambled eggs, leek fried meat, anyway, I love to eat leeks related to leeks, of course, planting a few ditches of leeks is also a must, almost every family in our rural area is planting leeks, saving time and effort, planting leeks for several years to eat, eat a stubble and cut a stubble, today plum blossom turnstile to share the experience of planting leeks.

Our leeks are generally divided into direct sowing and leek root transplanting two ways, the older people love to choose direct sowing, that must be patient, because leeks have just grown out of the fine, like some fine hairs, have to grow to a year to be strong. And I am a time-saving person, the natural choice is transplanting, that is, leeks that others have raised, I can plant leek roots directly, as long as the leek roots are selected, and then planted at the right time, transplant directly.

In fact, leeks can be transplanted in spring, summer, and autumn, which season can also survive, and it is best not to cut within half a year after transplanting, so that it can wake up better, and let the nutrients accumulate a little, which is more conducive to the growth of leeks, so that the leeks will be thicker. In this way, if the leek transplanting is selected in the spring, the spring leek is the time to be fresh, and you can't cut it in October after transplanting, and then it's cold and not long, this year can not be eaten, and it still occupies the ground. And transplanting in the summer is not suitable for cutting in the New Year.

In this way, it seems that spring and summer can be transplanted, but it is not the best time, and the best time for transplanting should be autumn July to August.

Plant cucumbers, kidney beans and other vegetables in spring, and in August, these vegetables are out of season to pull the shelf, then go to the market to buy some leek roots, cut the roots to leave about two centimeters, cut the stems to leave about three or four centimeters, and at the same time put the roots in the solution of pesticides mixed in advance, so that the leeks are not easy to attract maggots after transplanting, and then draw a small cluster of five centimeters apart, a small cluster is generally four to five leeks, and then water the soil, no matter how lush the leeks grow after waking up, An autumn and a winter call it naturally grow do not cut, and wait until the spring of the next year, the leek sprouts on the knife leek can be delicious, cut a stubble to feed a stubble, the longer the cut.

Now it's August, the bazaar has begun to sell leek roots, if you also have a soft spot for leeks, then hurry up to buy leek roots for transplanting, the survival rate of leeks after transplanting is very high, its growth capacity is particularly strong, water and fertilizer in place you just wait to eat leeks.

Autumn seedlings. Autumn sowing time.

There are two indicators that need to be mastered for autumn sowing of leeks, one is that the weather at the time of sowing should be cooler, and the average daily temperature should drop to 22; The second is to ensure that leek seedlings have a growth period of 50 to 60 days before wintering. The Langfang area is suitable for autumn sowing between the end of August and the beginning of September.

Prepare the land and make furrows. Yellow leek No. 1 F1 requires a large amount of fertilizer, is extremely resistant to fertilizer, and likes organic fertilizer. Therefore, before sowing, it is necessary to apply foot fertilizer and prepare the land carefully. When preparing the land, 5000 kg of decomposed organic fertilizer and 30 50 kg of ternary compound fertilizer (nitrogen-phosphorus-potassium is 15-15-15) are applied per mu.

After fertilization, turn it deeply, level it, and then make a furrow. Nursery furrows are 10 to 20 meters long.

When sowing and sowing, the furrow is sown along the furrow in the furrow, the furrow width is 10 cm, the depth is 1 cm, and the furrow spacing is 15 cm. Dry seed sowing is carried out directly in the ditch, lightly step on the sowing ditch after sowing, cover the soil with a flat rake, and then lightly step on the furrow surface after covering the soil, and then immediately flood irrigation with small water, and water 1 permeable water. On the 3rd day after sowing, spray the seedling furrow and its surroundings with 150 grams of herbicide pendimethalin (field supplement) and 50 kg of water per mu to control weeds.

Nursery management.

Before the leek seedlings are unearthed, they should be watered at any time to keep the surface moist at all times to prevent soil compaction from affecting the emergence of seedlings. The emergence period of leeks is 10 to 15 days, and after the seedlings are unearthed, they are watered once every 5 7 days. During this period, urea can be topapplied twice with watering, and 15 20 kg per mu each time.

After mid-October, watering can be controlled and top dressing can be stopped to promote the return of leek seedlings to roots. When the surface of the seedling furrow freezes at night and thaws during the day, irrigate 1 time of frozen water, and apply a layer of well-rotted cow dung or sheep manure on the surface of the seedling furrow after irrigation, so as to facilitate heat preservation and moisture preservation and safe wintering.

When is it better to transplant leek roots in rural areas? And how should it be transplanted?

When it comes to leeks, I think of leek dumplings, scrambled eggs with leeks, stir-fried meat with leeks and other common dishes. Leeks are very famous "lazy vegetables" and can be grown and harvested multiple times at once. In the countryside, almost every family grows leeks, saving time and effort, and there are leeks to eat for several years.

Leeks are generally divided into two ways: direct sowing and leek root transplanting. Older people like to choose to sow seeds directly, so you need to be patient; Nowadays, in order to save time, farmers generally choose transplanting.

In rural areas, the transplanting of leek roots is mostly done by buying bundles of leek plants during the spring market and transplanting them separately at home. In fact, leeks can be transplanted in spring, summer, and autumn in any season, and they can survive. But the best time to transplant should be in autumn from July to August.

If the first year is sown in autumn, and the leeks in the second year can be transplanted after they turn green and green, so how to transplant them?

1. Site selection. As long as the transplanted leeks do not appear to grow weakly, they will not be replanted within 2-3 years, so the land selection should be selected with fertile soil, and sufficient fermented farmhouse fertilizer should be applied.

And when choosing a land, we should pay attention to choosing a place that has not been planted with leeks, onions, and garlic for three years, which can prevent the spread of some pests and diseases.

2. Pruning. After leeks are planted, most of the leaves can be cut off to reduce water evaporation; The purpose of cutting off the front end of fibrous roots, leaving only part of the stems, is to promote the development of new roots.

When fertilizing, we can apply plant ash. Grass ash is not only a natural potassium fertilizer, but also protects the roots of leeks from pests and diseases. However, it is necessary to pay attention to uniform hole planting, planting too dense leeks will affect each other and limit each other, compete for limited resources, and affect the taste of eating.

3. Covering soil. After transplanting, it should be noted that the leek ditch after soil cultivation should be 5-6 cm lower than the row spacing, which is for the convenience of irrigation. After the soil is thoroughly watered, the transplanting work is over.

Leeks are watered twice a week after transplanting, no matter how lush the leeks grow after waking up, an autumn and a winter call it naturally grow do not cut, and wait until the spring of the next year, the leeks sprout on the knife leeks can be delicious, cut a stubble to feed a stubble, the longer the more you cut.

Under normal circumstances, in the countryside, leek roots are transplanted in the spring when the local temperature rises to more than 13-15 degrees, and now it is about to reach the hot summer, and it will not be long before the market will begin to sell leek roots one after another, if you also have a soft spot for leeks, then hurry up and act then! The survival rate of leeks after transplanting is very high, its growth ability is particularly strong, and you can wait to eat leeks when the water and fertilizer are in place.

<> 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.

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.
