What is the difference between bunching onion and fragrant onion? Detailed explanation of high-yield cultivation techniques

Bunching onion is also called four-season onion, vegetable onion, winter onion, frozen onion, etc. It is widely cultivated in the southern regions of our country. It is actually a variety of onion and an important seasoning, often used when cooking dishes and stewing soup. So where is the difference between bunching onion and fragrant onion? What are the high-yield cultivation techniques?

1. Where is the difference between bunching onion and fragrant onion?

Bunching onion generally has a plant height of about 20-30 cm, green leaves, cylindrical, hollow, tapering at the tip, white-green flowers, clustered into groups, the base of the bulb is easy to connect, growing in clusters, and when mature the outside is covered with a red membrane. The appearance of bunching onion is like a shrunken Welsh onion, with a long white stalk and slender pointed leaves, because it is indeed a variety of Welsh onion.

Fragrant onion has slender leaves, looks like bunching onion, and is also more closely related to Welsh onion. In some places, the plant called “small fragrant onion” is a different cultivar or variety of fragrant onion. There is another kind, called chives, also called northern onion and Ezo onion. Chives are the only Allium plant distributed across Eurasia and North America. We have wild species in Xinjiang. If it is blooming, you can recognize it at a glance, because its inflorescence is large and round, pink-purple, and very beautiful.

2. High-yield cultivation techniques for bunching onion

1. Land preparation and fertilization: Bunching onion requires deep, loose, and fertile sandy loam soil. Deeply plow the land, apply 4000 kg of high-quality farmyard manure per mu as base fertilizer, mix it evenly with the soil, make beds 2 m wide, rake the bed surface smooth, and open furrows in the beds 6-7 cm deep. For early-maturing cultivation, the row spacing is 20-25 cm; for general cultivation, the row spacing is about 40 cm.

2. Timely planting: Before planting bunching onion, prepare bulb seed balls. Separate the bulbs one by one and dry them in the sun for 1 day. About 50-60 kg of seed balls are needed per mu. For early-maturing cultivation, plant 2-3 seed bulbs per hole, with a hole spacing of about 15 cm. For general cultivation, plant 3-4 seed bulbs per hole, with a hole spacing of 20-25 cm. Plant in the furrows, cover with soil after planting, keep the bulbs 6-7 cm from the soil surface, and water after covering with soil.

3. Field management: Field management of bunching onion mainly consists of topdressing, stopping cultivation and weeding, watering and irrigation, and hilling for hardening. Topdressing is mainly with quick-acting nitrogen fertilizer. Starting from when the plant grows to 12-13 cm, apply topdressing once a month, for 3-4 times. Water once a month; in dry weather, appropriately increase the number of waterings. After the second topdressing, begin hilling, for a total of 2-3 hillings. Generally, hilling is done together with topdressing, that is, hill after topdressing. Each hilling should not be too deep, and it is best not to cover the white stalk.

4. Timely harvest: Except in the hot summer, bunching onion can be harvested in early summer, spring, and early winter. The specific harvest time varies with the variety and cultivation method. You can harvest only the leaves, and after each harvest, apply fertilizer once. You can also pull them all out, wash off the soil, tie them into small bundles, and sell them on the market.
