Cucurbits (scientific name: Lagenaria siceraria), also known as cucurbits, flat cucurbits, gourds, gourds, cucurbits, lagenaria [1], etc., is a plant belonging to the cucurbit family Cucurbitaceae cucurbitaceae, which is a climbing plant, and its fruit is also known as gourds.

The gourd was one of the first plants grown by humans for use as a container. It is estimated to have originated in Africa, and thousands of years of cultivated gourds have been found in present-day Mexico, Peru and Thailand. In Egypt gourds were used as burial objects. The earliest gourd skins unearthed at archaeological sites in Henan, China, date from seven to eight thousand years ago [2]. Gourd seeds found in Hemudu culture sites are also seven thousand years old [3], and some scholars suspect that the word referring to gourds (卣) already existed in the oracle bone inscriptions [4]. China first referred to gourds as gourds, lagenaria and pots. There are references to gourds in the Classic of Poetry and the Analects of Confucius. An example is "Eating gourds in July, breaking pots in August" in Shijing Binfeng - July (诗经-豳风-七月).

The gourd is an annual climbing herb with soft hairy, tendril-branched, oval leaves that alternate; white flowers in summer and fall, and monoecious plants.

Cucurbits have vines that can be up to 15 meters long, with hairy vines and oval or heart-shaped leaves. The fruits can vary from 10 centimeters to a meter, and the heaviest ones can weigh up to a kilogram. Cucurbits like warm, sheltered environments and need a lot of space when planted. Young seedlings are afraid of freezing. Fresh cucurbits have tender green skin and white flesh.
