Teacher, what is the best time to choose for leek rooting?

If you want to divide the leeks into roots, you should choose in autumn, because in autumn leeks begin to grow old slowly, which is the most suitable time!

It is best to choose the spring event for the root splitting of leeks, because the climate is more suitable at this time, and it can grow well for a long time. The autumn root division is due to the relatively short growth period, which is not conducive to the survival of leeks.

What is the most suitable time for leek roots, I think it is more appropriate to choose this time in spring, and the temperature at that time is also very conducive to the growth of leeks and leeks, so we can carry out three roots according to his physiological habits.

If the leek is divided, it should be an important part of its growth, that is, it can be in autumn, and autumn is also a very good time to divide the soup, and it can also be in summer.

Generally, it is better in the spring because leeks will jump roots, so after 2-3 years of planting, they need to be replanted, and the old roots will be pruned, and the teacher is polite! Thanks for the good reviews

Yes, leeks can be divided into many times, and autumn is also suitable!

I think spring is the most suitable choice, because spring is the time when everything recovers, and this is the time when leeks begin to grow vigorously and can be rooted.

Leeks are a very strong plant, and you can do it at any time, as long as it's not in winter.

I think it's better in the spring, spring

Well, hello, the root of leeks should be more suitable in the spring season, because in autumn, the weather is gradually cooler after the division of the family, and there is no benefit to leeks.

Leek root is best planted from late June to late July every year. The planting time of leek roots is generally in summer, and it can also be judged whether to transplant according to the growth of the plant. However, leeks can be transplanted when they have 4 or 5 leaves, or when they are about 17 cm tall.

In order to improve the survival rate of leek roots after planting, loose and fertile soil should be selected when planting, and humus, farmhouse fertilizer, and mixed into nutrient soil can meet the soil conditions required by leek roots, and can provide sufficient nutrients for them, so as to improve the survival rate of leek roots.

When planting, each seedling should be spaced 1cm apart, and the row spacing should be kept 15cm, so as to ensure that each seedling gradually has a larger growth space, and at the same time ensure that the seedlings can have sufficient nutrients.

1. Temperature: leeks like cold and cool, cold and heat resistant, the seed germination temperature is more than 12, the growth temperature is 15 to 25, and the underground can withstand lower temperatures.

2. Light: medium light intensity, strong negative resistance. However, if the light is too weak, the accumulation of photosynthetic products is less, the tillers are less and weak, the yield is low, and it is easy to premature aging. The light is too strong, the temperature is too high, there are many fibers, and the quality is poor.

3. Moisture: The appropriate air relative humidity is 60-70%, and the soil moisture is 80-90% of the maximum water holding capacity in the field.

The leek planting time is after the winter after the soil thaws to the autumn equinox can be sown at any time, generally in late March to early May, spring sowing is appropriate, summer sowing should be sooner rather than later. And because leeks are perennial vegetables, autumn sowing is very suitable. Therefore, in Shandong, the planting time of leeks is after September, and they can be sown in autumn.

Leek planting methods and precautions.

1.It generally takes 10 to 20 days from seed germination to the growth of the first true leaf. The suitable temperature for germination is 15 18, the lowest temperature is 2 3, and it does not germinate if it exceeds 20 degrees.

2.Leeks have a weak ability to unearth, pay attention to the thickness of the covering soil.

3.The fertilization law of leeks: the growth and fertilizer consumption at the seedling stage are small, but the peak vegetative growth period, especially in the spring and autumn harvest seasons, the growth and fertilizer requirements are large, and a large amount of fertilizer should be applied in stages.

2 4-year-old leeks have vigorous growth, strong tillering ability, high yield, and the largest fertilizer requirement, which is the peak of fertilizer demand. Leeks that are more than 5 years old gradually enter the senescence stage, and in order to prevent premature aging, it is necessary to strengthen fertilization.

4.Seedlings are unearthed, after the true leaves are released, the root system gradually increases, when the seedlings have 2-3 true leaves, you can chase the seedling fertilizer once, and water it in time after fertilization. When the seedlings have 4-5 leaves, they can be fertilized again.

The amount of fertilizer applied is basically the same as that of the first top dressing. Every 20 days or so in the seedling stage, fertilizer can be topped once, and drainage should be prevented from waterlogging, and the furrow surface should be kept dry and wet.

5.Timely top dressing: top dressing only after transplanting to survive, every 5-6 days to start harvesting, and then each harvest can be topdressing once or twice.

No fertilization is applied when moss is pumped, and fertilization is applied again after flowering to promote tillering. Fertilization time, once a year when the leeks are stopped to be harvested, when the leeks germinate 2 4 cm, combined with the cultivated soil to apply organic fertilizer once. Nitrogen fertilizer can not be applied alone when fertilizing, the time is mastered after each harvest of leeks 3 4 days after the new leaves grow and then applied, nitrogen, phosphorus, potassium, fully mixed, according to the ridge ditch application.

When planting leeks, they can be planted in the spring, summer and autumn of the year, but it is best to plant them mainly in spring 3 and 5 months, when the surface temperature and rainfall are more suitable for the growth of leeks, which is conducive to the formation and accumulation of leek nutrients.

Leeks are planted in 3-5 months.

Leeks are cultivated in many regions of our country, choose the right time to plant high-yield and high-quality leeks, then leeks are best sown in a few months, generally in the spring of March and May or about three days before and after the beginning of autumn planting is the best, or planted in June in summer, but mainly spring seeds.

Although leeks can be planted in spring, summer and autumn, most of them are mainly spring seeds, because leeks like to grow in a warm environment, the temperature and rainfall in spring are more suitable for the growth of leeks, and the appropriate surface temperature and air humidity are conducive to the formation and accumulation of leek nutrients, so the taste of leeks planted in spring will be particularly good.

If you plant leeks in spring, it is best to choose to plant when the surface temperature is about 5 10, generally in early spring, not suitable for late spring, the temperature difference in early spring can be conducive to the growth of plants, and the seedling rate will be very high, if you sow leeks in summer, you should usually strengthen fertilizer and water management, the sowing amount should be larger than in spring, and the surface covered soil can not be too thick, so as to ensure the normal emergence of plants.

The flowers of leeks planted in autumn are generally carried out in about three days of the beginning of autumn, and the sowing amount is twice the amount sown in spring.

Eating is Raihan's, and it can be planted all year round, and it can be planted in the winter, and it's really good anyway.

Leek (scientific name: a.) tuberosum rottl.

ex spreng.), a plant of the family Allium. Leeks are native to southeastern Asia and have been widely cultivated around the world.

Leeks are adaptable, cold and heat resistant. It has a special strong odor, the rhizome is horizontal, the bulb is narrow and conical, and it grows in clusters; Scaly outer skin yellowish-brown, reticulated fibrous; leaves basal, strip-shaped, flattened; Umbel inflorescence, apical.

Leek roots are generally transplanted in late July to early spring (if leek seedlings are thin and small, they can be transplanted in 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 depth of the ditch is about 15 cm, in the ditch according to the plant spacing centimeter seedlings, watering, covering soil, planting when the depth of the soil is not buried in the leaf node is appropriate, after the soil 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, and loosen the soil in time to squat the seedlings. 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.

Pest and disease control of leeks

The forest blight of leek source forest traces harms the roots, stems and leaves, especially the pseudostem bulb is the most affected. 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 hail, 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, you can spray 50% gray nucleus carb 1000 times solution or 40% sclerotia net 2000 times liquid for control, and spray the drug evenly after each leek harvest. 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.

<>1. Leek root transplanting is generally in late July to early August, if it is not a summer sown leek, then when the seedlings grow to 4-5 leaves, the plant height can be planted when it is 18-20cm. After all, leeks are very adaptable and can be transplanted in the three seasons of spring, summer and autumn.

2. Before transplanting, water it once and cut off the leaves on the ground. Remember to water thoroughly before digging the leek roots, in order to avoid hurting the roots when digging the leek roots.

3. Before planting, it is necessary to apply base fertilizer to the soil, and you can apply fully rotted farm fertilizer, such as pig manure, chicken manure, cow and sheep manure, etc. You can also apply some miscellaneous fertilizer, and in order to prevent leeks from raw maggots, you can mix some plant ash in the farm fertilizer, or spray 40% phosphine 800 times the solution. Crack Hui Qiao.

4. In fact, plant ash is a good farm fertilizer, when planting leeks, sprinkle more plant ash, you can prevent leeks from growing maggots.

Leek roots are usually planted between March and May and November and December.

Before sowing, the seeds were soaked in a 1000 times diluted solution of Wanli-T for 4 hours, the seeds were sterilized, washed with water, and then immersed in water for 48 hours. After the seeds are fished out of the water, they can be put into a small cloth bag or covered with a cloth in this booklet and placed at a temperature of 20C. To promote germination, it must be washed with water once a day, and after 2 or 3 days, the tip of the bud is revealed, and it should be planted immediately.

When sowing, it is advisable to first rake out a shallow furrow on the leveled furrow surface, 6 cm wide and about 2 cm deep. The seed strips are applied to the furrow, and after sowing, the furrow surface is swept flat, and the seeds are covered in the soil, and the loose soil is gently compacted. Watering is carried out immediately after sowing, and then every 2 days to keep the soil moist.

Others

Once the leeks are planted, they can only loosen the soil on the ground for 2 to 3 years, and cannot be deeply cultivated. Therefore, before planting, it is advisable to carry out deep ploughing to facilitate the development after planting. Before ploughing, it is advisable to spread the base fertilizer on the field surface, plough into the soil for full-layer fertilization and then make furrows, furrows wide meters (including furrows), 30 cm high.

If the groundwater level is high, it is advisable to use wide furrows and deep ditches to facilitate future drainage. After the furrow is flattened, the horizontal planting furrow is carried out, the depth of the furrow is 10 cm, and the distance between the furrows is 27 cm. In order to raise concerns about drainage during rainy seasons, the ring ditch should be deeper than the furrow to facilitate drainage.

About 70 days after sowing, it can be planted in this nursery, 1 2 hours before planting. The seedbed should be fully watered first to facilitate the excavation of seedlings and preserve the integrity of the root system, so it is better to choose the seedbed site with sandy loam or sandy soil.
