To grow onion a bow seems, at first glance, a very simple task. However, if you want to get large and dense heads, and not just green arrows, you will have to work hard. Basically, this concerns the correct pre-landing preparation and the observance of the timing of the landing of the sowing .
Preparing the onion for planting
First you need to carefully select the bulbs for planting, having eliminated soft, dried and too small. Then, to accelerate germination, it is necessary to cut off the husk, dry it in a warm and dry place and heat it for 2-3 weeks at + 20 ° C. Closer to planting, it should be warmed well at a temperature of + 35-40 ° C for 10 hours.
An important stage in the preparation of onion is its disinfection. Do this immediately before landing in the ground. The simplest and most effective method that our grandmothers used was the processing of onions before planting with salt and manganese.
At the first stage before planting, the onions are processed with salt. To do this, immerse the inoculum for 2-3 hours in saline solution, prepared from the calculation of 2 tablespoons of salt (stone or table) for two liters of water.
Processing of onions with saline solution will give the plant a rapid development and ensure its protection from the corrosive effects of the environment. Also, salt disinfects the onion from the nematode.
The second stage of preparation is the processing of onion in spring in spring before planting potassium permanganate. You need to dilute 35 g of potassium permanganate in 10 liters of water and immerse the bulbs in this solution for a couple of hours. This simple method is the most effective against any diseases. And although today many new preparations have appeared for processing, potassium permanganate has been and remains the most popular, since it is very effective at its cheapness.
Another option for presowing onion preparation:
- Before planting, the onion should be filled in a bucket and poured hot water (65-70 ° C) for 2 minutes, then dropped literally for a minute into cold water;
- then soak the bulbs in a nutrient solution (you can use 1 tablespoon of complex fertilizer per bucket of water) for 8-10 hours;
- drain the solution, and the bulbs, without rinsing, put in a solution of copper sulfate (1 teaspoon per 10-liter bucket of water) for 5-7 minutes;
- wash the bulbs and you can proceed to planting.
Preparing the soil for onion planting
If you want to grow a good crop of onions, it is not enough to only process the seeds, it is also important to choose the right place for planting and prepare the soil. And to start preparing beds you need from the autumn.
Bow loves good light and it grows best on sunny areas. Also, it is hygrophilous, and does not tolerate waterlogging. Because of groundwater or not at all, or they should lie at a considerable depth.
As precursors of onions, crops such as peas, potatoes, tomatoes or cabbage are most suitable. You can also plant carrots near the onion bed so that its phytoncides drive away the onion fly .
Since autumn, the selected site is to be dug up, to introduce the manure and peat. If the soil is acidic, it is necessary to carry out its liming in order to create
In the spring, before planting, fertilizer is not advisable, as this will allow many onions to come in, and the bulbs will not be large enough. You just need to loosen the bed, destroying the surface crust, and you can start planting prepared onions.
Plant the bulbs at a distance of 8-10 cm. It is necessary to cover the ground with the layer above the shoulders of the onion no more than 2-2.5 cm. When planting, it is necessary to water the bed. Further care consists in loosening, weeding weeds, watering.
