In green onions, there are a lot of microelements and vitamins useful for the human body, which are very necessary during the period of beriberi, observed in the spring. By regularly eating onion feathers, you can significantly reduce the risk of contracting viral infections. Compared to other crops, growing onions is not difficult, but to get a good harvest, it is important to properly prepare the soil and feed the crop in a timely manner.
It is especially important to apply fertilizer for onions on a feather into the soil during its active growth. Therefore, it is important to know when and what fertilizer to apply. This will be discussed in the article. But first, consider the question of how to choose a variety of onions for a feather.
Variety choice
In order for you to grow not only large bulbs in your garden, but also abundant green mass, you should choose the right crop variety, as well as fertilize it in time. So, the following varieties are suitable for growing green onions:
- Schnitt-onion. This variety is distinguished by narrow feathers, stretching in length by about 50 cm. With proper care from 10 m2 you can collect up to 30 kg of feathers. Chives have a pleasant aroma, feathers remain tender for a long time.
- Shallot. This is an unpretentious variety that gives a bountiful harvest from 10 m2 usually you can collect up to 40 kg of feathers.
- Tiered bow. Frost-resistant variety, high quality greens, does not require maintenance and easily survives the winter. Gives a lot of greenery.
- Onion-Batun. Planting material is very cheap. Does not form bulbs. It contains much more useful substances in comparison with other varieties of culture. With proper care, you can collect about 35 kg of greenery from 10 m2. The culture is perennial.
- Leek. It has a feather that looks like green garlic. Does not form a bulb, but has a thick white part. It is worth noting that it is the white stem that is usually used in cooking. With this crop planted at 10m2, you can get up to 20kg of pen.
- Slug Bow. Has feathers like garlic. Their structure is soft, with a slight garlic aroma. It contains a large number of useful substances. Onion slime has a pleasant taste. In the greenhouse, this variety can be grown year-round, and in open ground – until frost. It ripens quickly and has a bountiful harvest.
- Bow Parade. Differs in the highest productivity – on 10 m2 you can collect up to 65 kg of greens.
Features of growing in open ground
The crop varieties proposed in the article are planted in late autumn or early spring. At the same time, it is important to select only that planting material that has several primordia and its size in diameter is 3-4 cm.
Before planting the onion, the planting material is soaked in warm water and remains in it for the next 24 hours. To speed up germination, cut off the top of the bulbs. Thus, among other things, productivity is improved.
There are 2 ways to plant onions in open ground:
- The prepared planting material is placed in the grooves at a distance of about 4 cm from each other, and then the beds are leveled with a rake. In this case, there should be a distance of about 20 cm between the grooves.
- The onions are stacked close to each other, and from above they are covered with earth by 3 cm. In this case, by 1 m2 takes about 10 kg of planting material.
In the spring, this covering material is removed, and the onion plantings are covered with a protective film.
Another option is to sow onion seeds. This can be done closer to the middle of summer, after fertilizing and loosening the soil. Before sowing, the seeds must be soaked in a solution of potassium permanganate. So, they will be disinfected and less prone to disease. After the emergence of seedlings, the onions need to be thinned, leaving a distance of about 5 cm between them.
By winter, beds with onions, the greens of which at this point reach up to 25 cm, should be sprinkled with peat or covered with straw. So, after the spring snowmelt, you can pamper your family with green vitamins. So that you can use the green mass of onions in the summer, sowing seeds must be done in early spring.
Features of greenhouse cultivation
The best option for growing onions is by a closed method, that is, in a greenhouse. In this case, the crop can be harvested all year round. Greenhouse onions are best grown from mid-autumn to spring, and planted in a greenhouse from mid-winter to the end of May.
The easiest way to feed onions on a feather is to properly prepare the soil. To do this, it is best to choose boxes for growing, in which nutrient soil will be filled. It should consist of equal parts of fertile soil, peat and compost or humus.
Before planting, planting material is also soaked in warm water for a day. After, it can be planted close to each other, and then covered with a thin layer of soil. Until sprouts emerge, onion boxes can be stacked on top of each other, allowing you to make room for other crops. After 15 days, arrange the container around the perimeter of the greenhouse or greenhouse. At the same time, it is important to maintain the temperature of the air in the room. It should not fall below 18ºС.
Watering onions on a feather in a greenhouse during the growth period is carried out approximately 5 times. Between this, it is important to apply mineral fertilizers. When the greens reach a height of about 40 cm, then it must be cut.
Subject to agrotechnical rules, the onion yield will correspond to the crop variety. If you have the opportunity to heat the greenhouse, then planting onions can begin in October. To maximize the yield of onions for greens in the greenhouse, plant planting material with a multi-ring structure.
You can use Baikal, Epin and others.
When growing onions on greens, placing the bulbs close to each other when planted, the underground part of the plant will dry out, which allows its above-ground part to grow luxuriantly. In addition, this way, you will get greens with the maximum amount of vitamins and minerals. So that the soil does not acidify, and the underground part of the onion does not begin to rot, the plant should be watered rarely, but plentifully.
Additional recommendations
The yield of onions depends entirely on the conditions that are created for it. And if all the crop care activities are really done correctly, then the only problem that you will face in the fall will be the safety of the crop. There are several feeding options. It largely depends on what types of fertilizers you have. To make the soil more fertile, add superphosphates to it before planting.
However, organic fertilizers cannot be applied to the soil in its pure form. In order for onions to grow better, there must be a sufficient amount of nitrogen in the soil. If fresh manure is introduced into the ground, it will decompose for too long and the onion will not receive the nutrition it needs.
Excess nitrogen can cause the underground part of the onion to simply rot, so fertilization should be moderate. Therefore, for feeding onions, manure diluted in water is used in a ratio of 1: 3. If you decide to feed the onion with bird droppings, then it needs to be diluted much more, the ratio is 1:15. This is due to the fact that bird droppings are more saturated with nitrogen than other organic matter.
Soil mineralization
In the absence of organic matter, mineral fertilizers can be applied to the soil. Saltpeter, potassium salt and superphosphate can be used as top dressing.
So, you will need 1 tbsp. l. saltpeter, 1 tbsp. l. potassium salt and 2 tbsp. l. superphosphate. All this is diluted in a bucket of water.
When to Feed Onions
As mentioned above, the soil for onions can be fertilized before planting or during the period of active growth. For example, after the first thinning of the rows of onions. During this period, the culture especially needs saturation with phosphate and nitrogen.
The next top dressing is carried out in a few weeks. This time it is better to add organic matter to the soil. Alternatively, you can also mineralize the soil, but it is important to use preparations that do not contain nitrogen.
Basic care
After germination, you need to wait for the feathers to grow about 12-15 cm in height. Then you can thin out the onion, while removing weak and unhealthy sprouts. Winter onions need to be fertilized during this period. You can use organic, mineralization, or some combination of fertilizers.
Organic
Yes, you can add organics. Some recipes for making organic fertilizers have already been mentioned above, but below we will look at a few more ways:
- Fertilizer from horse manure. So, for 10 liters of water you will need 500 g of manure. This composition should be infused for a week. To fertilize onions, you will need to dilute the fertilizer: 5 liter of slurry goes to 1 liters of water. Watering is carried out in the aisles.
- Cow feeding. So, to prepare a composition useful for onions, you need to insist 500 g of mullein in 5 liters of water. After diluting the solution, it must be allowed to brew for a week. The proportion in which the mullein is bred is 1:5. Just as in the first case, watering is carried out between the rows.
Use of minerals
Infusions of mineral fertilizers do not need to be done. They are sold as powders or liquids that are diluted with water just before watering. It is worth noting that soil mineralization is carried out in 3 stages:
- After germination.
- 2 weeks after the first feeding.
- After 20 days. But the third feeding is carried out on infertile soil, and nothing more.
Experienced gardeners use 2 main schemes for applying mineral fertilizers to the soil.
The first feeding option in 3 stages:
- 2 tbsp. l. “Vegeta” are bred in 5 liters of water;
- 1 tsp the drug “Agricola – 2” is diluted in 5 liters of liquid;
- 2 tbsp. l. “Effekton – O” and 1 tbsp. l. superphosphate for 5 liters of rain / settled water.
The second option for feeding onions on a feather in 3 stages (all components from the list are diluted with 5 liters of water):
- 1,5 st. l. ammonia;
- 1 st. l. salt and the same amount of ammonium nitrate;
- 2 tbsp. l. superphosphate.
Combined fertilizer
Many specialists use combined fertilizers, even on an industrial scale. So, the fertilizer application scheme in 3 stages looks like this:
- 0,5 cups of manure infusion + 1 tbsp. l. urea + 5 l of water;
- 1 st. l. nitrophoska + 5 l of water;
- 5 g of potassium salt + 10 g of superphosphate + 5 l of water.
It is worth noting that for better yields, before planting or sowing onions, it would be good to disinfect the soil. For this purpose, copper sulfate is excellent, which is diluted with water in a proportion of 1 tbsp. l. for 10 liters of water. Before fertilizing the beds for onions per day, disinfection must be performed. Watering is carried out with a flow rate of 2 l / m2.
Conclusion
If you decide to grow onions for sale and you need the maximum amount of crop on a minimum area, then you need to prepare the soil in advance, and also apply fertilizer in a timely manner according to one of the schemes proposed in this article. By following all the recommendations, you can expect a bountiful harvest, either for your family or for sale.
