According to the local climate, soil and market demand, choose green onion varieties with fast growth, strong disease resistance, high yield and good quality. 2. Land preparation and sowing Site selection: Choose a plot with good drainage, deep soil and rich organic matter. Avoid planting in low-lying or poorly drained land to prevent the onion's root system from becoming flooded and becoming diseased. Land preparation: Loosen the land and till it to a depth of 20-30 cm to make the soil fine. Add an appropriate amount of organic fertilizer when preparing the land to increase soil fertility. Sowing: Choose the appropriate sowing time according to local climatic conditions and variety characteristics. Generally, seeds are sown in rows or in holes. The sowing density is about 15-20 grams of seeds per square meter. After sowing, cover with a thin layer of soil and water to keep it moist. 3. Seedling Management Watering: Keep the soil moist and water frequently during the growing period, but avoid excessive watering to prevent root diseases. Fertilization: Apply appropriate amount of nitrogen fertilizer according to the growth of onions during the seedling stage to promote the growth of seedlings. Thinning: When the seedlings grow to about 5-7 cm, thin them out to allow each seedling enough space to grow. 4. Management during the growth period Watering: Watering during the growth period of green onions should be moderate, both to keep the soil moist and to prevent excessive water from causing root disease. Fertilization: During the growth period of green onions, appropriate amounts of nitrogen, phosphorus and potassium fertilizers should be applied in a timely manner to meet the nutrients required for the growth of green onions. At the same time, adjust the amount and type of fertilizer appropriately according to the growth of onions and soil fertility. Intertillage and weeding: During the growth period of onions, intertillage and weeding should be carried out in a timely manner to keep the soil loose and remove weeds. Pest and disease control: Take appropriate prevention and control measures based on the growth of onions and the occurrence of local pests and diseases. Common diseases and pests include rust, downy mildew, gray mold, etc., which can be controlled by chemical agents or biological control methods. 5. Harvest and Storage Harvest: When the onions grow to a certain height (about 70-80 cm), they can be harvested. Avoid damaging the roots and leaves of the green onions when harvesting. Cleaning: Clean the harvested green onions and remove the yellow leaves and dirt from the roots. Storage: As needed, green onions can be stored in a cool and dry place, or processed and stored.
