When is the planting time of overwintering green onions?How and when to plant overwintering shallots

The planting time of wintering green onions belongs to, autumn planting time: sowing in early September in the autumn of the first year, overwintering with seedlings, planting in early to mid-May in the summer of the second year, harvesting before winter, overwintering in the cellar or open field, flowering in the spring of the third year, and harvesting seeds in the second season. Seedlings can be used as shallots from early May to late June.

Listing;It can also be planted in flat furrows before and after the beginning of summer (pinching onions) or narrowed row spacing to plant into ditch shallots as autumn shallots**, or as early spring onions after wintering**.

1. Spring green onion planting time: sowing after thawing the soil in early spring, as a shallot** before the arrival of hot summer, or harvesting as a dry onion or ditch onion ** in the year after planting. It can also be overwintered as a sage or as a seed plant.

2. Summer green onion planting time: mostly sown in late July to early August, so it is also called onion. The plants are larger when they overwinter that year. It is easy to complete the vernalization process, and the next spring germinates early and blooms quickly. Generally, it is marketed after receiving the horn onion.

The conditions under which green onions are grown.

1. Soil: green onions are suitable for loam soil cultivation, the seedling site requires loose fertilizer, sufficient bottom moisture, the seedling period should prevent topsoil compaction, and the seedlings begin to grow rapidly when they are topdressed once, and control soil moisture 10-15 days before planting to prevent lodging.

2. Fertilizer: Green onions like fertilizer, and require 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.

Particular attention should be paid to the application of phosphate fertilizer, as the lack of phosphate fertilizer can 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.

1. Planting time.

Winter shallots are best planted in October every year, adjust the time according to the local climate, if the temperature is low, you can choose to sow in early October, and in the south with high temperature, you can sow in late October. If the sowing time is early, it will suffer from low temperature and cause leaf death, if the sowing time is late, it will make the seedlings smaller, resulting in poor root development and easy death.

2. Organize the soil.

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

3. Seed treatment.

Before planting winter shallots, prepare the seeds first, you can determine the desired variety, and then select a full, full, disease-free new species, can not choose the old seeds, otherwise the germination rate will be reduced. Before sowing, prepare 55 minutes of warm water, soak the seeds for about 20 minutes, and then remove them to dry before sowing.

Fourth, carry out sowing.

Ditch according to the row spacing of 20-25 cm, water and soak thoroughly, then sow the seeds, cover them with thin soil, and wait for germination.

1. The planting time of overwintering shallots.

Overwintering shallots should be planted around October each year, on flat, well-drained plots with fertile soil. Overwintering shallots do not require high soil pH, but slightly alkaline soil will be more conducive to the growth of shallots. Before planting, the soil should be plowed deep and fertilized with the soles.

2. Thermal insulation treatment of overwintering shallots.

When planting overwintering shallots, its thermal insulation measures are very important, the easiest way is to plant the shallot seeds, cover some straw on the ground for heat preservation, but this insulation method, the shallot can only emerge after the spring of the second year, and the market time is relatively late. Another way to keep warm is to build a small arch shed, you can take some bamboo blanks to make a bracket, and then take an appropriate amount of plastic cloth to cover the bracket.

3. Field management of overwintering shallots.

The root system of shallots is relatively shallow, not suitable for applying thick fertilizer during the growth period, urea should be diluted into fertilizer water when topdressing, and then applied, in addition to the weeds in the field should be removed in time during the growth of overwintering shallots, and special attention should be paid to watering, not too much watering, should be used in the way of small water frequent watering, so that the soil can be kept moist. Shallots are mainly edible young leaves, and they should be harvested in time when they grow up, and the taste becomes worse after aging, which also affects its quality.

Hello, about your question I think that autumn 9-October sowing winter shallots. Shallots in the Yangtze River basin are generally sown in March and April and harvested in June and July; It can also be sown in 9 October and harvested in 4 May of the following year. During this period, the young seedlings that have not grown up are mainly eaten in the market.

It is advisable to choose flat terrain, good drainage, fertile soil for planting, regardless of sandy soil, clay loam soil, the soil pH requirements are not strict, slightly acidic to slightly alkaline. However, it is not suitable for many years of continuous cropping, and it is not suitable for stubble with other onions and garlic vegetables. After selecting the plot, it is immediately ploughed, and generally 2500 3500 kg of rotting manure or manure are applied per mu, plus 30 35 kg of phosphorus and potassium fertilizer, or 40 kg of compound fertilizer.

Due to the shallow distribution of onion roots, the absorption is weak, so it is not tolerant to thick fertilizer, not tolerant to drought and waterlogging, and the competitiveness of weeds is poor. After planting, tillering begins, and a second tillering can be extracted on the tiller. Generally, 2 to 3 months after planting, the clumps are more luxuriant and can be harvested.

3. All winter onions are called winter onions in our place. There are obvious regional and seasonal differences in the cultivation of green onions, like the main production areas of green onions in the north, green onions can be stored and cultivated in winter, and in spring, summer and autumn, they can also be cultivated with seeds for a short period of time, and they can be harvested and marketed at any time. However, in the warm areas of the south, it is mainly cultivated by dividing onions as fresh onions.

The cultivation of winter onions is mainly based on the white onion as the product**, so there are certain requirements for varieties.

First, the selection of varieties.

Winter onions should choose green onion varieties with high white yield and storage resistance, which is the basic requirement and the basis for obtaining high yield. For example, we often use Changbai green onion varieties here, which have high yield, good quality and good commerciality, and customers are willing to collect enough. The yield of short green onion white type is low, but the storage tolerance is better than that of long white green onion.

Chicken thighs and green onions are also available.

In the selection of varieties of winter shallots, it is necessary to determine the type of variety first, and then determine the variety to be cultivated according to the local cultivation and consumption habits.

Second, the cultivation season.

Winter onions are mostly seedlings raised in autumn, planted in summer, and harvested around winter, referred to as autumn sowing, summer planting and winter harvesting. In some areas, seedlings can also be raised in spring, such as early spring warms early, winter is cold late, green onion varieties with a long growth period can be sown and transplanted in summer.

We here winter onion is mainly autumn seedlings, can be sown after the white dew solar term, the green onion seedlings are required to grow three leaves before the winter is the best, water enough wintering water during the light snow solar term, cover the open field with manure or wind barrier insulation for winter, water back to green water in spring, when the seedlings are about 30 cm high in May, they can be transplanted.

Pay attention to fertilizer and water management after transplanting, before the arrival of the high temperature season in July, let the root system of green onion seedlings fully develop, the more nutrients accumulated, the more nutrients can grow slowly in the high temperature season without dormancy, and wait until the temperature drops in autumn, the green onion will quickly resume growth, and it can be harvested and listed during October.

Autumn sowing green onion seedlings must pay attention to the sowing date, if sowing too early, seedlings grow too much before wintering, affected by low temperature, early sprouting phenomenon will occur in spring. If it is too late and the seedlings have less than three leaves, they are prone to freezing to death during the winter. Therefore, the most suitable time for autumn sowing seedlings is mid-September to early October, that is, when winter wheat is sown.

If it's not suitable, or you want to sell shallots in the coming year, then you can stay in the field and not harvest them.

Third, green onions overwinter.

Winter onions are relatively cold-resistant, and they will not be frozen to death at a low temperature of -30, so they can safely overwinter in the open field.

Winter onion soil winter, that is, green onions at the beginning of winter do not plan, as the weather turns cold, to follow the two sides of the onion ditch soil, keep the green onion white from freezing, do not lose water, and wait until the first time can be planed with the market, the method is simple and easy, and the storage effect is better.

You can also take trench, frozen, cellar, or refrigerated storage after harvesting.

In short, the wintering of green onions is mainly to seize the sowing season of overwintering seedlings to ensure that green onion seedlings can safely survive the winter without being frozen to death, and the rest can be harvested at any time according to demand.

The planting period of overwintering green onions is generally in June of the following year.

In the seedling stage, the temperature is low, the growth is very small, and the nutrient requirement is also less. The spring rejuvenation to the planting period is the vigorous growth period of seedlings, which is the key period for cultivating strong seedlings. After planting, due to the high temperature in summer, the growth is stunted, and the nutrient uptake is very small.

As the weather gradually cools, the temperature difference between day and night increases, the plant growth rate accelerates, and the onion begins to elongate and thicken rapidly. In November, the temperature drops, and after the frost on the green onions, the growth of the plants almost stops, and the nutrient uptake drops rapidly.

The overwintering shallots are planted in September and October every autumn, and when planting the overwintering shallots, it is necessary to provide them with sandy loam soil with good drainage and air permeability and slightly acidic, and it is also necessary to place the overwintering shallots in a bright place, and also need to be watered according to the growth state of the overwintering shallots, so that they can grow vigorously.

1. Planting time

The best planting time for wintering shallots is in September and October every autumn, because planting at this time can make the wintering shallots have enough nutrition to survive the winter, but the specific planting time also needs to be adjusted according to the local ecological environment and climate conditions, and it is best to plant wintering shallots when the weather is fine.

2. Soil conditions

Overwintering shallots are suitable for growing in slightly acidic soil with good drainage and air permeability, when planting overwintering shallots, it is necessary to use sand, vermiculite, perlite in a ratio of 2:1:1 to mix the soil as a cultivation medium, and also need to apply ferrous sulfate to the soil to adjust the pH of the soil, so that the soil is slightly acidic.

3. Lighting conditions

Overwintering shallots are short-day plants, which need to be placed in a brightly lit place when planting, so that they can receive no less than five hours of natural light a day, so that overwintering shallots can carry out normal photosynthesis, and they also need to be moved indoors in rainy weather, and use plant fill lights to illuminate them.

4. Provide moisture

When breeding overwintering shallots, it is necessary to water according to the growth state of the plant, during the overwintering shallots seedlings, it is necessary to water every other week to keep the soil slightly moist, and during the vigorous growth of overwintering shallots, it is necessary to water every three days to provide the water needed for growth and promote the vigorous growth of overwintering shallots.

Overwintering green onions are sown better after the autumn equinox, generally between September 25 and October 10, after sowing to overwintering 45 to 55 days, before winter grow 2 true leaves, can safely overwinter.

Post-sowing management: autumn sowing is generally 6-8 days seedlings, due to the high temperature at that time, the seedbed should be injected with interest and moisturizing, and the seedbed should be removed in time when the mulch film emerges after sowing, and the seedbed watering should depend on the soil condition.

Generally, after the seedlings are raised, a small water is watered, and the soil is frozen and watered with wintering water.

After pouring frozen water, a layer of horse manure, soil miscellaneous fertilizer or plant ash of 1-2 cm can be sprinkled on the seedling furrow to help prevent cold and moisturize, and the seedlings can safely overwinter.

After the soil thaws in the spring of the next year, it is necessary to shout in time to imitate the mulch out of the furrow, when the seedlings grow 3 true leaves, combined with watering and top dressing 2-3 times, each time with about 15 kg of ammonium sulfate, or 6-7 kg of urea.

At the same time, after nearly greening, weeds should be pulled out in time for secondary seedling; About 7 days before planting, stop watering and return to refining seedlings to improve the survival rate of planting.

Before planting, the age-appropriate strong seedlings are 40-50 cm high, the stem thickness is cm, the root system is developed, the leaves are not yellow, there are no diseases and pests, and the area of 5-8 acres can be planted per mu of onion seedlings.
