The history of green onion cultivation

The earliest introduction of original varieties of green onions can be traced back to the records in the famous work "Guanzi" of the Warring States and Qi States: "In the fifth year of Duke Huan of Qi, he conquered the Shanrong in the north and obtained winter onions and peppers, which spread all over the world." The fifth year of Emperor Huan of Qi is roughly equivalent to 681 BC. This time is also the beginning of green onion cultivation in Zhangqiu area.

It can be inferred that green onions have been planted in the Zhangqiu area for nearly three thousand years, and were first introduced from the northwest minority areas. The "Zhangqiu County Chronicle" of the 9th year of Jiajing's reign in the Ming Dynasty (1530) also contains records about the cultivation of green onions, and four poems handed down by farmers at that time: "On the ninth anniversary of Jiajing in the Ming Dynasty, the fair lady climbed to the dragon's garden, long live the food. The praises are sweet and crisp, and the king of onions has given him the royal title."

This shows that in the Ming Dynasty, Zhangqiu green onions were crowned the king of onions. Green onions were widely planted in the Zhangqiu area and were used as tributes.
