The specific process of growing onions

Onion as a common vegetable in our life, it is different from garlic, onion and ginger. Onions contain a pungent smell that irritates the eyes and causes tears when chopping onions. There are still a lot of onions planted in our country, but there are still many people who don't know how to grow them, so today the editor brings you the specific process of growing onions. Let's take a look at it.

1. Select the place

Onions are adaptable and can grow normally in almost all soils, but the nutrient absorption capacity of onion roots is not strong. So when we plant onions, we should choose fertile and loose soil to promote the growth and development of roots. The soil can preserve fertilizer and water, and its permeability should not be too poor. And onions need a lot of light to grow, so choose areas with plenty of light.

2. Land preparation

After choosing the onion planting soil, it is necessary to carry out the work of soil preparation. When we prepare the soil, we have to determine the degree of soil preparation according to the water, fertilizer and permeability of the soil planted with onions. After soil preparation, the soil is loosened and exposed to the sun under the soil for 5-7 days to eliminate germs and parasites in the soil. Soil preparation is usually carried out together with base fertilizer, in order to improve the soil fertility and enhance the growth of onion seedlings.

3. Base fertilizer

As mentioned earlier, base fertilizer should be applied together with soil preparation, and the amount of base fertilizer should be determined according to the area of the soil. Base fertilizer can use fully mature farm manure, but the right amount of phosphorus, potassium, calcium and other elements should be added. When applying the base fertilizer, mix the base fertilizer and the soil evenly. After onion seedlings were unearthed, nitrogen fertilizer was applied in time to improve the growth rate of onion seedlings.

4. Sowing seeds

The correct sowing time is the key to ensure the normal growth of seedlings. Improper sowing time will hinder the growth of onions and affect the yield and quality of onions. The time of sowing in the south can be chosen in mid-September, according to the emergence of onions in the past, reasonable control of sowing, wait until the seedlings are unearthed in time to check seedlings and replenish seedlings. Cover about 0.7-1 cm of nutritious soil after sowing to ensure that the seedlings are unearthed.

5. Colonization

When about 80% of the seedlings are unearthed, you can start transplanting, but check the condition of the seedlings when planting. Filter some seedlings that are weak, overgrown and thriving. The seedlings with well-developed roots and uniform growth distribution were planted. According to the growth of onion seedlings, the seedlings with the same specifications are planted together to facilitate the later management and ensure the growth of the seedlings.

6. Management

After the seedlings are planted, attention should be paid to management to prevent the emergence of various pathogens such as downy mildew and Fusarium wilt, and to do a good job in disease prevention and control. Because the planting time of onions is mostly in autumn, when the temperature is low, it is not easy to water too much after planting, otherwise the surface temperature is too low and the growth rate of onion seedlings is reduced. However, it also needs a certain amount of water, so it is necessary to control the amount of watering during the seedling growth period to ensure that it will not affect the seedling growth but can provide the water needed for growth.

The above is the specific process of growing onions, onions are relatively easy to grow, but also need to have a correct process. So I hope you can master the correct planting method.
