Proper planting and care for onions in the open field

It is quite simple to grow high-quality onion heads from sevka, especially since the technology has many advantages. There is a high productivity, rapid ripening of root crops, the release of arrows occurs less often than when growing turnips. With proper care, planting in the open field does not cause difficulties.

Sowing sevka in the country can be in the northern regions, Siberian regions and Novosibirsk. It is important to observe the rules of sowing, care properly and protect from frost.

The correct time for planting onion sevka in open ground

The optimal period of the landing work - end of april. Early term due to the resistance of culture to cold. Also used a method of growing onions from sevka planted before the winter (in the second half of October).

Planting sevka at a later time leads to rapid drying of the upper layer, as a result of which the soil quickly loses the moisture accumulated during the winter. This negatively affects the rooting of the bulbs, which delays the emergence of shoots. As a result, roots are not fully mature.

Seeding planted in the Urals and in the regions of Siberia since the beginning of May (from 5-10 numbers) when the soil temperature is from +7 degrees.

Delay planting work is not worth it, it will reduce productivity. But it is also not necessary to hurry to throw the planting material into the cold land, this will lead to the release of arrows during the development of feathers.
To ensure a good harvest, delay planting should not be

Methods of growing and planting onions

Place under the beds is selected well sunlit and ventilated. It is necessary for normal growing season, eliminating the formation of rot and fungal diseases.

The soil is suitable light fertile neutral or slightly acidic. To reduce the acidity, lime is introduced into the soil (up to 4-5 kg ​​per hundred parts). Also suitable for these purposes: dolomite flour, wood ash, crushed chalk.

There is no need to break up the beds at the place where garlic is grown, the land after the savory culture is very depleted, which will reduce the onion harvest. But after tomatoes, eggplants, pumpkins, cereals and potatoes, you can plant sevok.

When enriching the soil with fertilizers, it is not necessary to simultaneously introduce lime into it, as this leads to a significant reduction in the amount of nitrogen. And it is necessary for normal growing season.

When preparing the beds for onions in the fall, humus (up to 5 kg per m2) is added to the plot. In the course of work, the earth is dug up to the depth 20 cm. Spring work begins with cleaning the area from debris and fertilizing the soil with minerals. Superphosphate (6 g / m2), urea (1 g / m2), potassium chloride (2 g / m2) are scattered on the ground and cultivated.

Mandatory preparatory stage is the disinfection of the soil. To do this, 7 days before disembarking, it is poured over with a solution of copper sulphate (a tablespoon of money in a bucket of water).

Copper sulfate solution is used to disinfect the soil.

Planting material also needs to be disinfected before planting. Proper preparation affects yield and crop resistance to diseases and pests. Sealing processing consists of the following steps:

  • soaking in a weak solution of potassium permanganate (copper sulphate 0.35%);
  • drying followed by storage for 20 days at a temperature +20 degrees;
  • heating the heads for 10 hours at a temperature +40 degrees;
  • seed treatment with growth stimulant.

Onion Sevok is grown in several ways:

  • in the spring;
  • before winter;
  • in the greenhouse;
  • bridge method.

Spring in the garden

Spring disembarkation is made according to the scheme:

  • interrow width at manual processing of beds - 25 cm (in the presence of the tiller - 60-72 cm);
  • hole spacing - from 5 to 10 cm;
  • immersion depth - 3-4 cm.
Planting onion sets in spring
The interval between the heads is selected depending on the diameter of the used bulbs: up to 10 mm should be indented 5 cm, up to 15 mm - 8 cm, over 15-20 mm - 10 cm.

After planting, the bed is mulched with a layer (2-3 cm) of peat, paper, sawdust, or other suitable materials.

Before the winter to the soil

The method of landing sevka for the winter has several advantages:

  • there is no need to ensure the storage conditions of the set in the winter period until the middle of spring;
  • early terms harvest (mid-July);
  • by the time pests appear, the culture is quite mature and mature.

On the vacant place you can have time to grow a crop of some fruits with a short period of ripening.

The peculiarity of the choice of the place for the bed is in the preference of the site located on a hill. There the snow melts faster, moreover, the meltwater stagnation is excluded.

The landing time is from October 5 to 20. Planting material should be properly prepared: calibrate, disinfect and heat. The scheme is used standard or with a narrow aisle. up to 15 cm. Sealing depth is 5 cm.

With the onset of cold weather, the bed surface is covered with mulch material. In the spring of the old protective layer must be removed.

In the greenhouse

Growing seed in a greenhouse provides for a number of preparatory activities:

  • disinfection of construction surfaces;
  • loosening the soil;
  • introduction of humus (5 kg per 1 m2);
  • fertilizer beds with minerals (superphosphate - 30 gr., potassium chloride - 15 gr.);
  • mixing and leveling the ground.

The seed is selected with a diameter of 30-50 mm. Any bad material is discarded. in the second half of October according to the scheme:

  • distance between the heads - 20-25 cm;
  • immersion depth - 4 cm.

On top of the beds, mulch of straw or sphagnum moss is covered with a layer up to 20 cm.

Spring work begins with the cleaning of the mulching material before planting and growing. Then fertilizers of nitroamofoska (up to 15 g / m2) are introduced twice. Irrigation is done as needed. Actively begin to rise in mid-April and early May. When the height of the pen reaches 20 cm, the crops are harvested.

Growing onions in the greenhouse

Mostovoy

This method of growing onions on the feather is used more often on balconies or in small greenhouses. The essence of the technology lies in the deepening of sevka in the ground in one row at a minimum rate without intervals between heads. Thus, it turns out the bridge, which served as the name of the method.

For the cultivation of the bridge method are selected onions with a diameter of 3-5 cm. Care includes watering and weeding. The soil should be constantly wet, it is important to water in the right proportions in time.

From bait is recommended to use:

  • superphosphate and potassium chloride - 2 g / 10 l of water;
  • ammonium nitrate.

Baits are introduced on the 8th and 14th day of the growing season.

Bridge way of landing onion sets

When rises

When growing planted on open ground with spring planting, seedlings appear above the soil surface on days 9-11. If the landing work was carried out in October, then the first green is breaking through, depending on weather conditions, more often it occurs in early to mid-April.

Greenhouse cultivation also guarantees different timing of emergence of seedlings, due to the type of construction and thermal conductivity of its surfaces. In the most common polycarbonate greenhouse you can see the greening soil from the soil at the end of February and the beginning of March.

When using the bridge cultivation method, the first shoots can be obtained 5-6 days after disembarkation.

How to care and loosen

For the growing season it is important to saturate the soil with oxygen, remove weeds from the beds, water the seedlings and introduce baits.

After emergence of shoots above the ground surface every 2 weeks to loosen the soil in beds to prevent earth formation.

Soil loosening should be done every 2 weeks.

This process is often combined with weeding to remove weeds, which creates favorable conditions for disease and rotting onions. Moreover, this neighborhood contributes to the formation of a thick neck, which subsequently complicates the drying of the crop.

Onion refers to the cultures that can do without bait, but this is when the soil is fertile. Many gardeners use 2-3 one-time bait mode:

  • 20-25 days after planting the seeding is carried out by watering with a solution of manure (1 kg per bucket of water);
  • application of mineral fertilizers (urea, nitrophoska) before irrigation.

Watering the beds is carried out with strict control of soil moisture. Lack of moisture is just as unacceptable as its abundance. If you carefully observe the plant, you can understand what the slightest changes indicate. Water should not be salty, when contaminated need to be slightly drained from the bucket.

The appearance on the leaves of a bluish-white shade indicates insufficient watering, and the paleness of feathers indicates an abundance of moisture. The first couple of months sevok irrigated weekly (7-8 liters per 1 m2). Since July, the amount of water is reduced, and 3 weeks before harvest, it stops altogether.

Strict soil moisture control is extremely important.
To protect against onion flies, it is recommended to use saline watering, which also stimulates plant growth.

200 grams of salt is taken on a bucket of water, the amount of liquid is prepared at the rate of 300 ml per bush. The procedure is repeated. 1 time in 3 weeks. If the treatment was ineffective, the concentration should be increased to 450 g / 10 l of water.

Is it afraid of frosts and what temperature can withstand

Onion is afraid of freezing and night temperatures below zero. The temperature indicators of the air at the landing should be within +12 degrees, the soil at a depth of 10 cm - not less than +5 degrees. Planting material germinates at 4-5 degrees. Ripe onions of specially selected varieties withstand frost down to -7 degrees, while sweet varieties die at -4 degrees.

When choosing a set, the climatic conditions of the region should be taken into account in order to give preference to the corresponding varieties.

Onion care is quite simple, if done properly preparatory work. Monitoring the state of the feather of the plant will be a hint, and the plan of measures will not let you forget about important procedures that guarantee a high yield.
