How to plant onion seeds? A detailed guide to the latest growing methods
Onion is a common vegetable in our daily life, with high nutritional value. Onions are propagated by sowing when planted, so how should onion seeds be planted? Let's take a look at the detailed introduction.
1. Seed selection
When planting, first choose suitable seeds for planting. Generally, seeds from the current year should be chosen, which can increase the sowing germination rate. If old seeds are chosen, the seeds have a limited lifespan, and old seeds have lower vigor. The longer they are stored, the lower the germination rate, and they are difficult to germinate after planting, causing losses to farmers. At the same time, also pay attention to whether the seed color shows signs of pests or diseases, and whether the surface color is bright.
2. Sowing time
Sowing time is extremely critical, as it is related to the yield and quality of onions, so sowing time must be taken seriously. Although onions can be planted all year round, they prefer a cool environment and have strong cold tolerance. At high temperatures above 26 degrees, they enter a dormant state and stop growing. Therefore, it is recommended to plant from July to September, when the temperature is about 20-25 degrees. After sowing, onions will grow extremely quickly, which can improve yield and quality.
3. Seed soaking and sprouting
⟦NL>To increase the germination rate of seeds, sprout them before sowing. This not only improves the seed germination rate but also makes the seedlings grow uniformly. First, soak the seeds in warm water at about 50 degrees for 4 hours. After they fully absorb water, rub and wash off the waxy layer on the surface, and sow after drying.4. Sowing method
The soil for sowing onions must be fertile, loose, and well aerated. You can also mix garden soil with decomposed farmyard manure to make the required fertile, well-aerated soil. Then water the soil thoroughly, keep it covered with a layer of fine soil, and scatter the seeds on the soil. After sowing, cover with plastic film and control the temperature at about 20 degrees. After about a week, the seeds will germinate. Do a good job of seedling management, thinning and filling in seedlings in time, and promote seedling growth.
