Green onion cultivation technology and green onion cultivation time

As one of the common vegetables in our daily life, green onion is not only delicious and nutritious, but also has good medicinal value. Therefore, mastering the planting time and method of green onions is of great significance to improving yield and quality and meeting daily needs. Let’s talk about the green onion cultivation technology and green onion cultivation time.

1. Planting time

The planting time for green onions is usually in spring and autumn. Spring planting generally takes place around March, while autumn planting takes place around September. In the southern regions, due to the warmer climate, the planting time may be advanced accordingly.

2. Planting Method

1. Soil selection

Green onions need deep soil with good drainage to grow. Therefore, when choosing a planting site, you should choose soil that is fertile but not too sticky. Before planting, the land needs to be deeply plowed and ploughed to increase soil permeability and drainage.

2. Seeding and seedling raising

Onion seeds can be sown directly in the soil, but in order to increase the survival rate and yield, seedling cultivation is generally required. When raising seedlings, you need to select healthy seeds, sow them in loose soil, and then cover them with a thin layer of soil. During the seedling raising period, the soil needs to be kept moist and care needs to be taken to prevent the invasion of pests and diseases.

3. Colonization

When the onions grow to a certain height, they need to be transplanted. When planting, the onion seedlings need to be dug out and then planted in the soil at a certain distance. The planting depth should be based on the height of the onion seedlings, and generally should not exceed the white part of the onion. After planting, the soil needs to be kept moist and protected from pests and diseases.

4. Fertilizer and water management

Green onions need sufficient water and nutrients to grow. During the growing period, it needs to be watered regularly and an appropriate amount of fertilizer should be applied. Generally speaking, green onions require fertilizers that are rich in nitrogen, phosphorus, potassium and other elements, as well as appropriate amounts of trace elements such as iron, zinc, copper and so on. When applying fertilizer, you should pay attention to controlling the amount and frequency of fertilizer application to avoid negative impact on the growth of onions.

5. Pest and disease control

Green onions may be attacked by pests and diseases during their growth. Therefore, during the planting period, it is necessary to regularly check the growth of green onions and promptly detect and prevent diseases and pests. Generally speaking, biological control and chemical control can be used for prevention and control. When using chemical agents, care should be taken to choose low-toxic, low-residue agents to avoid negative impacts on the environment and human body.

3. Notes

1. The growth of green onions requires sufficient light and ventilation, so when planting, you need to pay attention to choosing the appropriate planting density and spacing to ensure that the growth of green onions is not affected.

2. When planting green onions, care must be taken to avoid continuous cropping with similar vegetables to reduce the occurrence of diseases and pests and the impact on yield.

3. When harvesting, be careful not to over-dig or damage the white part of the onion, so as not to affect the quality and value of the onion.

In short, the cultivation of green onions requires attention to many aspects, including planting time, planting methods, fertilizer and water management, and disease and pest control. Only by doing a good job in these aspects can we ensure the good growth, high yield and excellent quality of green onions.
