How to grow scallions for high yield? A detailed guide to high-yield scallion cultivation techniques
Scallions are an indispensable side vegetable in our daily lives. They can be used for seasoning, adding aroma, and effectively helping to stimulate the appetite. Whether grown on a large scale for market sale or at home for self-sufficiency, they occupy a considerable planting area. However, many friends find that the scallions they grow are not only unattractive in appearance but also particularly low in yield. So how should they be grown to achieve high yield? Below, the editor brings you high-yield cultivation techniques for scallions.
1. Planting method
When consumers buy scallions, they judge them by the length of the white portion and how upright they grow, so we must lay a good foundation at planting time to ensure the length and uprightness of the white portion. Before planting, prepare the planting holes well, and make sure the seedlings are planted upright rather than at a slant. Also, the planting depth must not be too shallow. If the planting depth is too shallow, the white portion will be very short, but they also must not be planted too deep, because this will affect the seedlings' sprouting. Control the planting density properly. Although scallions are relatively small, the garden must still have good air circulation.
2. Reasonable watering
During the growing process, watering should be carried out reasonably according to factors such as growth rate, weather and soil. However, watering needs to be done at several specific times. For example, when summer turns to autumn, water appropriately to promote the growth and development of scallion roots. If the weather is not too dry, we should appropriately reduce watering. If the rainy season comes, pay attention to water accumulation in the vegetable garden and drain it in time. Too much accumulated water will affect root respiration and cause root rot. After entering autumn, water demand decreases, so a little light watering can be given appropriately. After Frost's Descent, it is enough to keep the soil moist.
3. Fertilization management
During the growing process, the amount of nutrients will directly affect the growth of scallions, and scallions have a relatively high nutrient demand. This is especially true during the vigorous growth period, which is the most critical stage. If sufficient nutrients are not guaranteed, the quality of the white portion will be reduced, such as its length and firmness. When topdressing, mainly use farmyard manure. Do not apply only one kind of fertilizer or apply too much of a single fertilizer, especially nitrogen fertilizer. Various compound fertilizers should be used reasonably to effectively promote growth. The two most important topdressing times are during the seedling growth period and the vigorous growth period of the white portion. At these two stages, fertilizer supply must be guaranteed to promote scallion growth and high yield.
4. Proper hilling
As mentioned earlier, the quality of scallions is mainly determined by the white portion, and improving the quality of the white portion depends on hilling. During the growth and development of scallions, hilling should be carried out at least three times. The purpose of hilling is to loosen the soil better, enhance soil permeability, and promote root respiration. It can not only effectively prevent abnormal growth and lodging of scallions, but also benefit the growth of the white portion and increase yield. However, everyone must pay attention not to let the soil cover the white portion when hilling.
The above are the high-yield cultivation techniques for growing scallions. Of course, during the growing process we still need to pay attention to the prevention and control of pests and diseases, since this is an aspect that requires our attention in cultivation. Strengthen vegetable garden management, reduce latent pathogens in the garden, and lower the disease incidence. That is all for today's introduction. I hope everyone can draw some inspiration from this article.
