The time of planting onions should be determined according to different varieties, different geographical environment, climatic conditions and so on. However, in general areas, it is recommended to plant in September-October every year, because the temperature during this period is more suitable, the weather is cool, and the germination rate is relatively high. If planted in advance, it is in summer, the temperature is relatively high, onion sprouting is relatively slow, affecting its growth.

Second, the planting method of onion (onion)

1. Sowing seeds

Onion planting generally choose the way of sowing, onion seeds are relatively hard, before sowing, it is recommended to soak the seeds to accelerate germination to improve the seed germination rate. Soak the onion seeds in cold water for a day, then fish them out, put them in a cool and ventilated place, wash them once a day, and wait until the onion seeds show a large area of whiteness.

Sowing the seedbed is also critical, try to choose a good loose, breathable, more fertile soil, before sowing to give plantar fertilizer, so that its smooth growth.

2. Management at seedling stage

To promote the germination and emergence of onion after sowing, it is necessary to keep the soil moist. Water control should be carried out when the seedlings grow two or three true leaves. The seedlings of onions should be fertilized properly, and farm manure is generally selected for ripening. At ordinary times, we should pay attention to the weeding work in the garden to avoid weeds and onion seedlings competing for nutrients.

3. Colonization

The key point of planting is to screen out healthy onion seedlings, get rid of diseased seedlings and thin seedlings, and leave seedlings with good growth, uniform size and no disease attack. When planting onions, we should pay attention to the planting density, not too dense and sparse, according to the fertility of the soil.

4. Water and fertilizer

The impact of watering onion for a month after planting is relatively great, and both flood and small water will affect its growth, so it is necessary to control the amount of watering each time, according to the wettability and growth of the ground. Onion within a month to rely on base fertilizer on it, a month later will be extra topdressing, remember to apply fertilizer frequently, thin fertilizer, after fertilization to be properly watered.

5. prevention and control of diseases and insect pests

Onion is more vulnerable to root rot, onion flies, so to do a good job of prevention and control, once the disease occurs, the spread rate is very fast. In addition, we also need to pay attention to bird damage, you can be a dummy to drive birds.

To sum up, onion planting time, seedling treatment, water and fertilizer are the key points, we must master it well.
