1, sowing
Onion planting is generally carried out by sowing. Onion seeds are hard, so it is suggested to soak seeds to accelerate germination before sowing to improve seed germination rate. Soak the onion seeds in cold water for a day, then take them out, put them in a cool and ventilated place, and wash them once a day. You can sow them after a large area of onion seeds appears white.
The seedbed for sowing is also very important. Try to choose soil with good porosity, strong air permeability and relatively fertile soil, and fertilize the soles of feet before sowing to make them grow smoothly.
2. Management of seedling stage
To promote the germination and emergence of onion after sowing, it is necessary to keep the soil moist. When two or three real leaves grow out of seedlings, water control should be carried out. Onion seedlings should be properly fertilized, and farmyard manure should generally be selected for decomposition. Attention should be paid to weeding in the garden at ordinary times to avoid weeds and onion seedlings competing for nutrients.
3. Planting
The key point of planting is to screen healthy onion seedlings, remove diseased seedlings and thin seedlings, and leave seedlings with good growth, uniform size and no disease attack. When planting onion, we should pay attention to the planting density, not too dense and too sparse, depending on the fertility of the soil.
4. Water and fertilizer
One month after the onion is planted, the influence of watering is relatively great, and large water or small water will affect its growth, so the amount of watering should be controlled every time, according to the humidity and growth of the ground. The onion in one month can rely on basic fertilizer, and after one month, additional topdressing is needed. Remember to apply fertilizer frequently and thinly, and water it properly after fertilization.
