Cucumber (Cucumis sativus Linn, English name Cucumber) belongs to Cucumis of Cucurbitaceae. Also known as gourd and cucumber. The fruit is oily green or green with soft thorns on the surface.

Widely cultivated in all parts of China, and now widely cultivated in temperate and tropical regions. Cucumber is one of the main greenhouse products, because it likes warmth and is not cold-resistant.

Cucumber was brought back to the Central Plains by Zhang Qian in the Western Han Dynasty, and it was called cucumber. The word "Hu" was taboo by Emperor Shile of Zhao after the Five Dynasties and Sixteen Countries, and was later changed to "cucumber" by Fan Tan, the county magistrate of Han Dynasty.
