In about a week, the green onions will emerge, and then apply nitrogen fertilizer once, and spray no-labor dew, dew sujing and other agents to avoid continuous disease and promote the rapid growth of green onion seedlings.

2. Transplanting and planting

It is advisable to choose a plot with high terrain, good drainage, and fertile soil to plant green onions, and when planting, it is necessary to apply plantar fertilizer and compound fertilizer, and then plough and turn over to improve soil fertility, plant green onion seedlings into the ditch according to a certain spacing, step on the soil after planting, and water once according to the water requirements of green onions.
