Onion planting time and method planting whole process

Onion planting time

Due to the influence of different onion varieties, geographical environments, climatic conditions and other factors, it is generally recommended to plant onions around September-October each year. Because the temperature during this period is relatively suitable for the growth of onions, the chance of germination is also relatively high. If you want to plant onions in advance, you need to pay attention to the temperature during planting. When the weather temperature is high, the germination speed of onions will become slower.

Onion planting methods and key points

1. Planting

The key point of planting is to select healthy onion seedlings, remove bad seedlings and small seedlings, and leave the seedlings with good growth, uniform size and no disease. When planting, pay attention to the planting density of onions, which should be appropriate and determined according to the fertility of the soil.

2. Planting

Onions are generally planted by broadcasting. Because onion seeds are relatively hard, it is recommended to soak the seeds for germination before sowing to increase the germination rate. When a large area of ​​onion seeds turn white, they can be sown.

3. Lighting

Onions are long-day vegetables. They need more than 14 hours of sunlight a day to grow normally. If the temperature is high and the sunlight is short, only leaves will grow and onions will not form.

4. Moisture

Onions need sufficient water at all stages of their growth, but they need to be water controlled during the seedling stage and before winter. To prevent the seedlings from growing wildly and suffering from frost damage, the humidity in the air can be kept at 60%~70%. Excessively high air humidity can lead to the occurrence of diseases.

Onion planting precautions

1. Water and fertilizer

One month after the onion is planted, it is necessary to water it, but too much or too little water will affect its growth, so the amount of water should be controlled every time, and it should be determined according to the moisture of the ground and its growth. At the same time, the onion within one month only needs basal fertilizer, and after one month, it is necessary to apply topdressing, which can be applied frequently and thinly, and water appropriately after fertilization.

2. Prevention and control of diseases and insect pests

Onions are more susceptible to root rot and onion flies, so prevention and control work must be done. Once the disease occurs, it spreads very quickly. In addition, you also need to pay attention to bird damage. You can make a dummy to drive them away.
