Planting method and time of Bailu onion

When planting white dew onions, we should pay attention to seed selection, stubble selection, soil preparation and sowing, and watering with frozen water. The time is usually between the Millennium and the autumnal equinox, about August.

1. Select stubble

Choose Zhangqiu, ocean green onion, etc. You can also use your own fine farm varieties.

Choose stubble

Avoid continuous cropping of green onions and choose plots that have not been planted with onions, leeks and garlic for 3-4 years. Wheat, corn, potato and other crops should be used as good previous crops, and sandy loam or loam is better.

3. Soil preparation and sowing

After selecting stubble, plow and rake the land in autumn, and apply fertilizer appropriately in combination with the land preparation area. When sowing, the width is generally about 10 cm, and the ditch depth is 3-4 cm.

Pour in frozen water

Autumn seedlings have three true leaves, and the height of the seedlings is about 10 cm. At the end of June, freezing water was poured around 10, and thin manure was poured once in combination with fertilization to raise the ground temperature, and then a layer of raw manure was covered to ensure safe wintering.

Pay attention to the sowing date, sowing too late, the onion seedlings are weak, easy to die in winter, and the growth and development are slow after turning green in the second year, which affects its maturity and yield; Sowing too early, pulling weeds and sowing in the next spring is not suitable for planting onions. The suitable sowing time is 60-70 days before the onion stops growing, and the onion seedlings grow to two leaves and then thaw.
