The following is to share with you the cultivation method and time of onions.

When is the planting time of onions?

Different varieties of onion will have certain differences in planting time, but the approximate sowing time is mostly concentrated in the first ten days of September, that is, before and after the white dew solar term, which is the best time point for onion sowing.

When the buds are exposed, they can be sown.

2. How to grow onions? What are the planting methods?

1. Soil preparation

In order to prevent diseases and insect pests and ensure onion yield, it is necessary to carry out soil preparation treatment before sowing. The plot can be deeply turned, then exposed to sunlight for about 2 days, and then decomposed base fertilizer is applied to the soil to make the soil and fertilizer fully mixed.

2. Seedling management

After sowing, it is best to cover the soil with a layer of straw, and then keep the straw moist, and then remove the straw after the onion seedlings grow.

3. Colonization of onion seedlings

When onion seedlings grow about 4 true leaves, they can be planted. When planting, they should be selective. To eliminate diseased seedlings, short seedlings and excessive seedlings, it is best to classify onion seedlings.

The planting time can be selected at the end of October. The row spacing can be selected about 20 cm *15 cm.

4. Field management

After planting is completed, it is necessary to have the best corresponding fertilizer and water management and pest control.

(1) Fertilizer and water management: urea, nitrogen, phosphorus and potassium compound fertilizer are the main topdressing, and topdressing is carried out in the vigorous growth period and bulb expansion period. Each topdressing can be combined with watering.

(2) Pest control: The diseases mainly include downy mildew, purple spot and rust. The pests are mainly onion thistle. Generally, it is serious in rainy weather. Therefore, it is key to do well ventilation treatment. Check the field in time. Once the disease occurs, prescribe the right medicine in time.

Pay attention to not watering onions one week before harvest, otherwise the harvested onions will not be able to withstand storage and affect returns.
