How to protect green onion seedlings in winter?How to plant green onions in winter

Land selection and land preparation, winter planting of green onions need to choose a deep soil layer and convenient drainage and irrigation plots, before sowing the plot needs to be turned over and fertilized;Before sowing seedlings, it is necessary to dig a trench with a spacing of 15 cm in the soil before sowing, and spread the seeds evenly into the soilWatering and moisturizing, after the planting is completed, it is necessary to water the rooting water once, <>

When planting green onions in winter, it is necessary to choose a plot with deep soil layer and convenient drainage and irrigation for planting, and after the plot selection is completed, it is necessary to carry out live farming, remove the weeds and gravel in the plot, and mix with sufficient amount of well-rotted organic fertilizer to improve the fertility of the soil, so as to speed up the growth rate of green onions.

Green onions can generally be sown for seedlings, need to dig a shallow trench with a depth of 15 cm according to the row spacing on the furrow, and then evenly spread the seeds into the soil and cover a thin layer of soil. Due to the low temperature in winter, after sowing, it is necessary to cover the soil with a layer of plastic film to keep warm and moisturize.

After the green onion is planted, it is necessary to water the root water in time, and the amount of watering should not be too large, so as to ensure that the soil is in a slightly moist state. After 5 6 days, it is necessary to apply another slow seedling water, wait until the frost falls, water every 10 15 days, and water again before the winter solstice.

When planting green onions in winter, it is also necessary to carry out topdressing in time. The first topdressing should be carried out during the vigorous growth period, the second fertilization should be carried out during the period from cold dew to frost, and the third topdressing should be carried out between the beginning of winter and light snow, and the fertilization was mainly based on the application of diluted urea fertilizer and potassium fertilizer.

How to winter shallots: Arrange soil, fertilizer, temperature, water, and light.

1. Tidy up the soil

If the soil is alkaline, you can add pentachloronitrobenzene to adjust the acidity of the soil and promote the soil to maintain a reasonable pH value. Combined with deep ploughing and application of rotting farmhouse fertilizer, keep the soil loose and fertile, and do not choose the soil where onions and garlic are planted in the previous crop.

2. Fertilizer

Onions like fertilizer, and require a balanced application of nitrogen, phosphorus, and potassium. In the early stage of growth, more nitrogen fertilizer is required, and more phosphorus and potassium fertilizer are required in the later stage. Special attention should be paid to the application of phosphate fertilizer, because the lack of phosphorus fertilizer will lead to poor plant growth and reduced yield.

At the same time, it is necessary to pay attention to the content of sulfur in the green onion ground, and the lack of sulfur in the soil will affect the yield increase effect.

3. Temperature

Onions are stress resistant, hardy to both cold and heat. Although temperature does not have much effect on the growth of green onions under normal circumstances, the right temperature conditions are conducive to high quality and high yield.

4. Moisture

The onion has few root hairs and poor ability to absorb water and fertilizer. The root system is mostly distributed in the surface layer of the soil, likes moisture, and requires high soil moisture, but the root system is afraid of waterlogging, and high temperature and high humidity are very easy to cause root death5. Light

Onions require moderate light intensity. Because the cylindrical leaves of green onions can still get good light conditions under dense planting conditions, they do not need strong light. Strong light has an adverse effect on the growth of green onions, which will cause leaf aging, fiber increase, quality decline, and even loss of edible value.

Land selection and land preparation: deep ploughing of soil that is convenient for irrigation and drainage. Sowing seedlings:

Make a shallow furrow with a row spacing of 15 cm in the furrow and sow the seeds into it. Field management: Green onions should be watered in time after planting.

Precautions: When planting green onions in winter, you can generally top dressing 3 times.

1. Land selection and land preparation

Before planting green onions, it is necessary to prepare soil with sufficient sunlight, convenient irrigation and drainage, and rich in organic matter, and carry out deep ploughing, clean up the weeds, gravel and other debris in it, and then break the soil clods and rake them flat, and apply rotten fertilizer.

2. Sow seeds and raise seedlings

Green onions are generally sown with dry seeds or strip sowing, sowing is to sow a layer of fine soil on the sowing furrow as a covering soil, the furrow should be filled with water source, and then the seeds are scattered in, and then covered with thin soil, strip sowing is in the furrow according to the row spacing of 15 cm to open a shallow ditch of 15 centimeters, and the seeds are sown in.

3. Field management

Green onions should be watered in time after planting, the amount of water is not easy to be too large, 5-6 days later, and then watered 1 time to change the seedling water, and then every 7-8 days to water 1 time, wait until the frost falls, every 10-15 days to water 1 time, and then water 1 time frozen water during the winter solstice.

4. Precautions

Planting green onions in winter, generally top dressing 3 times, the first top dressing is carried out when the plant grows vigorously, the second top dressing is carried out during the cold dew to frost fall, and the third top dressing is carried out between the beginning of winter and light snow, and the fertilizer is mainly urea and potassium fertilizer.

Hello, how to protect a large number of green onions from green onion farmers for winter, the following methods are recommended for you: 1. Ditch storage: remove the diseased and injured plants after drying the green onions for several hours, and then bundle them into green onions and put them in a ventilated and good place until the surface moisture of the green onions is completely dried in the shade; Dig a ditch in the shade and ventilation, about 33 cm deep, about 150 cm in the ditch, depending on the storage capacity, the ditch spacing is 50-70 cm; Plant the green onion into the ditch, and then bury the white part of the green onion with soil; Place the green onions in the corner of the wall or in a cool room with the shade on your back, and then bury the green onions with wet soil around the green onions to the green onion leaves.

2. Burying: Put the green onions that have been dried, selected and bundled in the corner of the wall in the shade or in a cool room (spread a layer of wet soil on the ground), and then bury the green onions with wet soil around the green onion leaves; Or you can choose to bury it outside, but be careful to cover the grass before the cold comes, in case the green onions are frozen. 3. Ganzang:

The harvested green onions are dried for 2-3 days, during which the soil on the roots should be knocked off and the diseased plants and wounded Zhu should be removed, and when the green onions are dried to 7 percent, they will be tied into green onions weighing about 1 kg. Put the green onions in a dry and ventilated place (single-layer storage), and pay attention to the heat and moisture prevention measures during the period.

How to plant shallots in winter to grow better, rural beauties will explain to everyone.

Green onion production areas in northern China are mostly transplanted with seedlings. Most of the main producing areas in the middle and lower reaches of the Yellow River are sown in autumn, but the seedlings should not exceed 3 leaves before winter. The south of the Yellow River is mostly sown in spring, and the sowing should be done as soon as the local temperature reaches 7. Green onions are suitable for loam cultivation.

The nursery land is required to be loose and loose, and the bottom moisture is sufficient. At the seedling stage, it is necessary to prevent topsoil compaction, top dressing once when seedlings begin to grow rapidly, and control soil moisture 10-15 days before planting to prevent lodging. From June to July, the row spacing of long-white varieties was 70cm, and the row spacing of short-white and chicken leg varieties was about 50cm, and the plant spacing was about 5cm.

In order to increase the depth of the false stem into the soil, the ditch depth of the Changbai variety (below the ground level) is 15cm, the depth of the ditch of the short white variety is about 10cm, the bottom of the ditch is loosened, the green onion seedlings are planted in the ditch, the depth of the soil is 5-7cm, and the normal growth of 1000 kg of green onions needs to absorb nitrogen kilograms, phosphorus kilograms, and potassium kilograms. When the soil hydrolyzed nitrogen is less than 80 ppm during the growing period, it is necessary to apply fast-available nitrogen fertilizer. Phosphorus and potassium supplementation can increase yield and improve quality.

The management of the high temperature season is mainly to prevent waterlogging and weeding and protect seedlings, and sufficient soil moisture is required during the vigorous growing season.

Soil cultivation prevents the lodging of green onions and softens the false stems, which is an important part of the cultivation and management of green onions. When the plant begins to grow vigorously, and the height of the false stem exceeds the ground level, the Yongtu flat furrow is carried out in combination with top dressing. When the false stem is about 10cm above the ground, the soil is raised.

Landrace varieties were soiled twice, and the false stems were 30-40cm into the soil. The short white and chicken leg varieties are cultivated once, and the false stem is about 20cm into the soil. If there is no soil during the growth period, the plants can be discharged upright in a softened bed after harvesting, and the sand can be filled from the gap between the false stems, and the bottom of the bed can be kept moist and the upper part can be protected from rain.

Softening can be completed in 25 days in the warm season and about 40 days in the cold season. This method has a large softening loss, but it can be densely planted during the cultivation period, and it is easy to obtain high yield.

Green onions have a wide range of adaptation to temperature, and can be harvested and eaten from seedlings to before sprouting. In addition to cultivating green onions that are fully grown in autumn, shallots (green onions that have not grown up sufficiently) are cultivated and harvested in other seasons.

Seed. There are two types of seed collection: adult and semi-adult. Adult plant collection:

The green onion that grows fully in autumn is used as the seed, which is convenient for strict selection, but the cost is high, and it is used when propagating the original seed; Semi-adult seed collection: sowing and cultivating semi-grown mature plants in summer as seed plants, planting before winter, low cost, and shortening the cycle by one year. Green onions are easy to cross-pollinate, and the varieties should be isolated from each other.

The green onions harvested in early winter are arranged into bundles after being harvested and dried, and discharged in a shallow ditch in the shade. It can be stored for more than 100 days at a low temperature below 0, and the onion bundle should be kept lightly frozen during the storage period to avoid repeated thawing. The air humidity should be about 80%, which can be covered with grass to moisturize and prevent rain.

Green onions have no natural dormant properties. Although the false stem can be stored for a long time at room temperature, it has a large loss.

Planted in highlands with good drainage.

1. Prepare green onion seedlings. Choose straight and dry shallots with good white onions, remove the dead leaves on them, and use scissors to cut the shallots short, which is conducive to the green onions to fully absorb the water in the soil. Pick a spare.

2. Prepare the soil. You can pick up soil under the bushes in the park, or you can buy it at the flower market. It is best to fill about three-quarters of the container you have prepared. Because when the green onions are planted, the container is full.

3. Implement onion planting. Fill a small part of the prepared high-quality soil into the foam box, and then plant the green onions prepared in advance into the soil in the box with the roots facing down at a certain distance. You can plant in 2 rows, 5 trees in each row, stagger the empty pendulum, do not put too densely, and then continue to fill the soil until the box is full.

Make the green onions stand one by one. Solidify the soil, dig a small trench along the edge of the box with a shovel, and pour the right amount of water into the trench with a kettle.

4. Daily management. Keep it bright and water in moderation. After a week, tender green green onion leaves will grow.

When picking, pick the outer layer of plump green onion leaves carefully, do not hurt the green onion stem, and do not light the leaves at one time, the leaves can be photosynthesized and promote the growth of green onions. The green onion leaves can be used to make chopped green onions, cold vegetables, scrambled eggs, etc. In addition, the appearance of green onions is very beautiful, the vitality is very strong, put on the windowsill, the emerald green color undoubtedly adds a beautiful scenery to the winter interior.

In order to strengthen the disease prevention ability of onion seedlings, foliar spraying of supplementary potassium fertilizer can be carried out with filtered aqueous solution of plant ash, and it is recommended to use water-soluble potassium fertilizer of sea meal. It can also be sprayed with potassium dihydrogen phosphate liquid of sea meal fertilizer powder to make the green onion seedlings grow strong and improve the ability to resist diseases and wind.

Green onion seedlings: If you want to grow green onions indoors in a pot in winter, you need to prepare green onion seedlings first. When choosing green onion seedlings, it is necessary to keep the green onion white intact, then clean up the dead leaves of the green onion, and then cut the green onion leaves short with scissors, so that the green onion can better absorb the water in the soil.

Soil: When planting green onions, the soil requirements are not very high. We can choose the soil in the bushes, or we can buy the flower soil directly, and fill the pot with green onions about 3 4.

Plant green onions: Plant green onions in pots, if the pot is small, plant a green onion is fine. If the pot is large, you can plant two more trees in moderation. But when planting green onions, be sure to pay attention to the spacing, and water the right amount after planting.
