Seedling-raising methods for Welsh onion seeds

1. Seed selection

For seed selection, it is best to choose new seeds from the current year. When selecting seeds, wind selection or screening is usually used. The screening method can select seeds that are large, plump, and of high specific gravity, while also removing a certain amount of debris, keeping the seeds clean. The screening method uses standard-hole sieves to remove shriveled seeds and keep plump seeds.

2. Sunning the seeds

Choose clear weather, spread the seeds for seedling raising in a place with sufficient sunlight, and sun the seeds for 2 days to 3 days, for 3-4 hours each day. But note that the location should be bare ground, not a cement surface or asphalt road; otherwise, the ground temperature is higher and can easily scorch the seeds.

3. Soaking seeds to promote sprouting

Soak the seeds in clean water and stir for 10 minutes, remove the blighted seeds and impurities, then put the seeds into warm water at about 60 degrees and soak for 20-30 minutes, stirring constantly so the seeds are heated evenly, and the water temperature naturally decreases.

4. Seedling raising

Welsh onion usually uses open-field seedling raising. For the seedbed, it is suitable to choose sandy loam soil that is fertile, rich in organic matter, flat in terrain, loose in texture, and convenient for drainage and irrigation. Apply an appropriate amount of decomposed farmyard manure and superphosphate per mu, then level the land and make beds, with shallow plowing and fine harrowing.

5. Sowing

The sowing methods for Welsh onion include drilling and broadcasting. If the bed surface is slightly dry, you can first water the ground, then level it, open furrows, sow, and cover with soil; if the bed surface moisture meets the seeds' needs, directly sow the seeds evenly in the furrows and rake the bed surface firmly. Next, tread it firm and water.

6. Emergence management

At emergence, if the temperature is low, it may take about 10-20 days to emerge. To promote emergence, you can cover the bed surface with a layer of film. If the temperature is high, they can emerge in 6-8 days. When they are about to emerge, water once to cover the heads. Before the cotyledons have straightened, water once again as well, to avoid the bed surface crusting and affecting soil aeration.

The above is an introduction to Welsh onion varieties and seedling-raising methods. When farmers grow Welsh onion, understanding a good seedling-raising method can save time and effort in the early stage and ensure product quality and increase yield in the later stage. Reasonable and effective use of seedling-raising techniques is an important foundation for ensuring high yield and increased income of crops.
