The custom of eating yam in the New Year comes from a legend: eating yam at night and not taking medicine the next year. And yam has a beautiful meaning, representing health and happiness. For everyone who has experienced the epidemic, nothing is more important than health, so we might as well add a plate of yam to the table during the Spring Festival to add a good wish for the new year.

Distribution area

Now it is cultivated everywhere.

growing environment

Born in Xiangyang, Shan Ye.

Growth habit

Wild in the sunny areas of mountainous areas, they like to be warm and cold-resistant, and they can overwinter with a little covering in the north. Because yam is a deep-rooted plant, sandy loam with deep soil layer, good drainage and loose fertility should be selected in the planting area.

Neutral soil has the best pH value. If the soil is acidic, it is easy to produce branches and nodules, which will affect the yield and quality of roots. Over-alkali, its roots can't grow down sufficiently. Therefore, in the south of China, appropriate amount of lime should be applied to the soil with strong acidity to neutralize the soil acidity.

Breeding mode

It is mainly propagated by reed heads and bulbils (yam bean).
