Scallions are a must-have for many households in the northern region. Many people also plant some green onions for daily consumption. In the process of planting green onions, there is a high demand for the temperature at the time of sowing. The following is a small series of Huinong. I will talk about the planting conditions and planting methods.
Soil
Scallions prefer to survive in slightly acidic soils, and the soil to be planted is preferably loose and fertile with sufficient sensation. In addition to the fertility of the soil, before the emergence of green onions, we must pay attention to the management of the soil, to avoid soil compaction leading to poor emergence.
2. Fertilization
Green onions are very popular with fertilizers, but they also require an average of nitrogen and potassium. In the early stage, the demand for nitrogen fertilizer was very high, and in the later stage, a lot of phosphate fertilizer may be needed. The growers should adjust the fertilizer according to the different growing seasons of the green onions.
3. Temperature
Green onions are hardy and heat-resistant, and growth is not difficult, but the temperature is better when the yield is high. The root system of the green onion is basically distributed on the outermost layer of the soil. It prefers moist conditions, but it cannot be excessively accumulated. Therefore, the green onion soil is often kept moist, and there is no water accumulation.
4. Lighting
Green onions are not very light-demanding, because in the case of very close planting, the green onions still have better light-receiving ability, so they can be productive without strong light. And the light is too strong, which will cause the leaves of the green onions to age.
5. Seeding
September is a good time to plant green onions in the fall. In May of the coming year, transplanting and planting can be carried out and harvested before winter. In the third year, seeds can be harvested after flowering.
6. Colonization
Before planting green onions, growers need to separate the seedlings and seedlings, and remove the diseased and weak seedlings. In the process of planting green onions, it is necessary to pay attention to controlling the density. More than 30 plants can be planted per meter, and the row spacing should be kept at about one meter. You can plant 20,000 plants per mu. Be careful to plant water immediately after planting.
The above is the small onion planting conditions and sowing and planting methods compiled by Huinong. The green onions are always in great demand in our lives. Friends who want to grow green onions must learn the cultivation techniques.
