Planting onions in spring needs to pay attention to choosing suitable land. In spring, the temperature is suitable, there is no rainstorm, and the soil humidity is suitable. It is best to choose well-drained soil. Variety selection. The onion varieties planted in spring should be cold-resistant, precocious and resistant to pests and diseases. For example, "Crown Grape", "Middle Early Maturity" and so on. Ridge and trench excavation. Trenching depth is 20 ~ 25cm and width is15 ~ 20cm. Ridge and furrow spacing is selected according to onion varieties.

Onions planted in spring need weeding and loosening in time. At the same time, attention should be paid to the prevention and control of pests and other diseases in the soil.

Plant spacing and row spacing of onion cultivation

1, plant spacing

The spacing between onions determines the size and growth of plants. If the spacing between plants is small, onion plants will grow well, but the growth consequences will be dense and more screening will be needed. If the plant spacing is too large, the onion plants will be too dense after growing, which will lead to a smaller ball head per plant. Therefore, the onion spacing should be controlled as far as possible between 10 and 15 cm.

2. Line spacing

The row spacing of onions should be selected according to the growth period and market demand. If the onion is planted for a long time, it is suggested to keep the row spacing of 10~20 cm; If it is planted temporarily, the row spacing can be appropriately expanded. Generally speaking, good growth effect can be obtained when the row spacing is 25~30 cm.
