1. There is no difference between scallions and scallions. scallions are a variety of scallions. Lamb's horn scallions are also known as Louzi scallions, yellow scallions, etc. Lamb's horn scallions are on the market just after the supply of dry scallions ends and before the harvest of scallions. The leaves are long conical and hollow. The pseudostem is short, and the part buried in the soil is white. When mature, it turns into a brown-red onion coat that wraps the pseudostem.

2. Spring onions should be planted late in spring seedlings, densely planted in small ridges, and the yield increased by the number of plants planted. Generally, the row spacing is 30 cm, the plant spacing is 5 to 6 cm, and 35,000 to 40,000 seedlings are planted in 667 m2. Lamb's horn onion likes a cool climate and has strong cold tolerance. The underground bulbs of the Louzi onion variety cultivated in the north can survive the winter safely in the open at temperatures as low as zero degrees Celsius.

3. There are sporadic plantings in some areas of my country, as well as in Russia, Japan and other countries, and there are more in Yanbian area in my country. The pseudostems and young leaves of scallions are used as seasonings in dishes, and the fatter aerial bulbs on the flower stems are also edible. The scallion has a very strong aroma and is a rare type of scallion that can be eaten raw, stir-fried, and used as a seasoning.

4. According to the length of growth time, green onions in the northern region include scallions, ground scallions, shallots, improved scallions, ditch scallions, green onions, old scallions and other varieties. The shape of the above-ground part of the green onion plant is very much like an onion, with cylindrical and hollow leaves. Its leaf sheaths and stems are included into pseudostems. If soil is cultivated and softened, a stick-shaped "green onion" will be formed. Green onions are the main edible part.
