Green onions are a widely grown vegetable and a plant with relatively high water requirements. Correct watering methods can effectively improve the growth rate and yield of green onions, so it is very important to master the appropriate watering time, frequency and method.

1. Growth needs of green onions Green onions are a common vegetable that likes to grow on fertile land with sufficient sunshine. Its growth process requires sufficient light, suitable temperature and humidity, and requires relatively high soil fertility and moisture.
2. The principle of watering green onions The principle of watering green onions is to keep the soil moist but not excessively moist to avoid standing water or drought. At the same time, the time and frequency of watering should also be controlled to avoid causing soil hardening or excessive moisture.

3. The watering requirements for the green onion growth cycle vary according to different stages of the green onion growth cycle. Generally speaking, in the early stage of green onions growth, appropriate amount of watering is needed to promote root growth; in the medium stage, the amount of watering should be controlled to avoid soil hardening; in the later stage, the amount of watering needs to be reduced to ensure the quality of the onions.
4. The best time to water green onions is in the morning or at night, avoid watering at noon or under the scorching sun. Because the scorching sun will accelerate the evaporation of water and excessively dry the soil, which will adversely affect the growth of green onions.
5. The frequency of watering green onions The frequency of watering green onions should be determined based on the local climate, soil fertility and growth stage of green onions. Generally speaking, green onions should be watered 1-2 times a day in the early stage of growth, once every 2-3 days in the middle stage, and once a week in the later stage.

6. Methods of watering green onions There are many methods for watering green onions, such as spraying, drip irrigation, bubble irrigation and ground irrigation, among which drip irrigation and bubble irrigation are the most suitable. These two methods allow water to fully penetrate into the deep layers of the soil to avoid excessive wetting of the surface and drying of the deep layers.
7. Precautions when watering green onions During the watering process, attention should be paid to controlling the amount of water to avoid excessive watering causing soil water. At the same time, spraying water on the leaves of green onions should be avoided to avoid causing the breeding of diseases.
8. Preparations before watering green onions Before watering, weeds and residues on the soil surface should be cleaned up to avoid adverse effects on the growth of green onions. Irrigation facilities should also be checked to ensure that the water source is stable.
9. Drought treatment during the growth of green onions In the growth of green onions, if drought occurs during the growth of green onions, water should be replenished in time. Generally, drip irrigation or bubble irrigation can be used to replenish water, and at the same time, pay attention to keeping the soil moist to avoid severe dryness.
10. Flood prevention treatment during the growth of green onions During the growth of green onions, if excessive water accumulation occurs, drainage should be carried out in time. Soil water accumulation can be prevented by improving soil drainage capacity and strengthening soil ventilation.
11. Combination of fertilizer and water during the growth of green onions During the growth of green onions, the combination of fertilizer and water is very important. Appropriate fertilization can promote the growth and development of green onions and increase yield. However, attention should be paid to controlling the amount of fertilizer and avoiding excessive fertilization.
12. Foliar spraying during the growth of onions During the growth of onions, foliar spraying can increase the absorption of nutrients by onions and promote growth and development. However, attention should be paid to selecting appropriate fertilizer varieties to avoid excessive spraying, causing leaf burns and other phenomena.
13. Influence of weather changes during the growth of green onions on watering During the growth of green onions, weather changes will have a certain impact on watering. For example, drainage should be done in time during rainfall to avoid excessive wetting of the soil; in high temperature and dry weather, the frequency and amount of watering need to be increased to ensure that the soil is moist.
14. Ripening and harvesting of green onions After the green onions mature, they should be harvested in due course. Generally speaking, green onions will appear withered after they mature and can be harvested at this time. Water should be stopped before harvesting and the soil should be gradually dried for easy excavation and storage.
15. The watering of green onions is an important management task. Attention should be paid to keeping the soil moist, controlling the watering time and frequency, and avoiding drought or water accumulation. Reasonable watering methods can promote the growth and development of green onions and improve yield and quality.
