When is the planting time for Chinese onion (Allium chinense)? Planting methods and high-yield cultivation techniques

AbstractSeed selection: Chinese onion (Allium chinense) reproduces asexually, and after harvest it can be planted directly as seed, generally using the semi-recumbent method. Soil: Choose sandy soil with good drainage; after one year of planting in a plot, it needs to be rotated with other vegetables that are not in the pungent/spicy aromatic category. Land preparation: Apply sufficient base fertilizer, and dig drainage ditches running north-south alongside, so that drainage is smooth. Management: Apply fertilizer in a timely manner and prevent pest and disease damage, and that is all.

Friends in the north may rarely see fresh Chinese onion (Allium chinense); what they are more likely to see is pickled Chinese onion. Chinese onion mainly grows in the south. When I was little, going with the adults to dig Chinese onion was also a great joy. Next, let us learn about the planting time and cultivation techniques of Chinese onion.

Planting time and methods of Chinese onion (which month to plant)

The planting time for Chinese onion is generally from the end of September to early October. If planted too early, the Chinese onion seeds are not so easy to sprout; if sown too late, the temperature will be relatively low at that time, and growth will be relatively slow, thereby affecting yield.

When planting Chinese onion, place the Chinese onion diagonally in the dug planting furrow, then cover with a layer of soil about 7 cm thick. Do not cover too thickly, to avoid making it difficult for the Chinese onion to sprout and emerge from the soil, and do not cover too thinly, to avoid the roots and stems being washed by rain during later growth and exposed above the ground, causing them to turn green from light exposure, affecting appearance and quality, and thereby affecting planting returns.

High-yield cultivation techniques for Chinese onion

Chinese onion is very easy to plant, and it does not have great requirements for the growing environment or climate; in that case, yield is also not strongly guaranteed. If you want to grow high-yield Chinese onion, you must also pay careful attention to the following points.

1. Chinese onion generally reproduces asexually, and the previously harvested Chinese onion can be planted directly as seed. First, we should choose sandy soil with good drainage. Slightly clayey soil can also be used for planting, but the yield is not as high as when planting in sandy soil. Moreover, the roots of Chinese onion can secrete a sulfide called propenyl, which can inhibit the growth of soil microorganisms. Therefore, Chinese onion cannot be planted in the same plot every year; it needs to be rotated with other vegetables that are not in the pungent/spicy aromatic category.

2. Before planting Chinese onion, the soil needs to be thoroughly plowed once, sufficient base fertilizer should be applied, and drainage ditches running north-south should be dug alongside, so that drainage is smooth.

3. Choose strong, sturdy Chinese onion seeds, cut off the dead leaves and dead roots, and then planting can begin. We generally use the semi-recumbent method for planting, so that the new roots and stems can grow better in the soil. After planting, cover with soil about 7 cm thick.

4. Chinese onion is relatively easy to manage in the later stages; just apply fertilizer in a timely manner and prevent pest and disease damage.

The planting method for Chinese onion is relatively simple, but if you want to grow high-yield Chinese onion, in addition to understanding the above methods, friends should also ask the older generation for advice more often and learn from their planting experience, so as to avoid getting half the results with twice the effort.
