How to plant green onions
1. Separate small and large seedlings before planting, and remove diseased seedlings, weak seedlings, too small seedlings and obviously bent seedlings. The spacing between plants is 35-40 plants per meter, and the spacing between rows is 1 About 23,000 plants are planted per acre. When planting, avoid breaking the green onion seedlings. The planting depth should not bury the heart of the green onions. Too deep will not allow seedlings to sprout. Too shallow will affect the white length of the green onions. When planting, the leaves and planting trenches should be arranged in a vertical direction to facilitate dense planting and management.
2. The planting tool can be a garden iron skewer or garden wood pole with a diameter of about 1.5 cm. When planting, first make a shallow hole, perpendicular to the ground, then insert the seedling, and then lift it up slightly to allow the roots to grow. Spread downward and keep the onion seedlings straight. If it is bent, the stem will also be bent when harvested later, and it will become a defective product.
3. Planting should be done on the same side of the onion ditch, which is beneficial to drainage after rain.
4. After planting, compact the loose soil on both sides of the onion plant, and then water it thoroughly.

Cultivation conditions of green onions
1. Soil: Green onions are suitable for cultivation in loam soil with a pH of 6.5-7.5. The nursery land needs to be fertile and loose. The bottom moisture is sufficient, and the topsoil should be prevented from compacting during the seedling emergence period. Topdressing is done when the seedlings begin to grow rapidly. The soil moisture should be controlled 10-15 days before planting to prevent excessive growth and lodging.
2. Fertilizer: Green onions like fertilizer and require balanced application of nitrogen, phosphorus and potassium. It requires more nitrogen fertilizer in the early stages of growth, and more phosphorus and potassium fertilizers in the later stages. Special attention should be paid to the application of phosphate fertilizer, because lack of phosphate fertilizer will lead to poor plant growth and reduced yield. At the same time, attention should be paid to the sulfur content in the onion land. Sulfur deficiency in the soil will affect the yield increase effect.
3. Temperature: Green onions are stress-resistant and resistant to both cold and heat. Although temperature does not have much impact on the growth of green onions under normal circumstances, suitable temperature conditions are conducive to high quality and high yield.
4. Moisture: Green onions have few root hairs and poor ability to absorb water and fertilizer. The root system is mostly distributed on the surface of the soil and likes moisture. It requires high soil moisture, but the root system is afraid of waterlogging. High temperature and high humidity can easily cause root death.
5. Light: Green onions require light intensity. Moderate. Because the tubular leaves of green onions can still get good lighting conditions under dense planting conditions, they do not need strong light. Strong light has an adverse effect on the growth of green onions, causing leaf aging, increased fiber, reduced quality, and even loss of edible value.
