Green onions are a common seasoning in our daily life and an indispensable ingredient in cooking. However, when planting shallots, the problem of rotten roots is often encountered, which not only affects the yield and quality of shallots, but also leads to the death of shallots. So, how to plant green onions to avoid rotten roots?belowHaifu AgricultureLet's introduce some practical methods for you.
1. Choose the right soil.
Green onions prefer to grow in fertile, well-drained soil. Therefore, when planting green onions, it is necessary to choose soil with good air permeability and smooth drainage, and avoid using soil that is too sticky and heavy to prevent root rot caused by too much moisture.
2. Reasonable watering.
Green onions need plenty of water, but too much water can also lead to root rot. Therefore, it is important to pay attention to the appropriate amount when watering and not to let the soil get too wet. Generally speaking, the amount of watering should be decided according to the climate and soil moisture, and the soil should be kept moist. During the rainy season, it is necessary to pay attention to timely drainage to prevent water accumulation and root rot.
3. Control fertilization.
Fertilization is one of the important measures to promote the growth of green onions, but excessive fertilization can also lead to root rot. Therefore, when fertilizing, it is necessary to pay attention to the appropriate amount and not to overfertilize. Generally speaking, fertilizer can be added in moderation every time you water to promote the growth of green onions. At the same time, it is also necessary to pay attention to choosing the right fertilizer and not using too much nitrogen fertilizer, so as not to cause overgrowth of the plant and reduce the resistance.
Fourth, strengthen the prevention and control of pests and diseases.
Pests and diseases are also one of the main causes of root rot. Therefore, it is necessary to pay attention to strengthening pest control when planting onions. Generally speaking, it is necessary to regularly check the growth of green onions, and find and improve pests and diseases in time. At the same time, it is also necessary to pay attention to the use of appropriate pesticides for prevention and control, so as to avoid using too many pesticides to cause environmental pollution and food safety problems.
5. Choose the right planting time.
Planting time is also one of the important factors affecting the growth of green onions. Therefore, when planting green onions, it is necessary to pay attention to choosing the appropriate planting time. Generally speaking, spring and autumn are the best times to plant shallots, as the climate in these two seasons is suitable for the growth of shallots. At the same time, it is also necessary to avoid planting in the hot and rainy season to avoid root rot caused by too much water.
To sum up, it is necessary to pay attention to choosing the right soil, reasonable watering, controlling fertilization, strengthening pest control and choosing the appropriate planting time. Only by doing these measures well can we make green onions grow healthily and improve yield and quality.
