The development history of Zizania latifolia

The Book of Rites says "eat snails and soup". The food is rice, so it can be seen that the seeds of Zizania latifolia have been used as food in the Zhou Dynasty. In Zhou Li, rice, together with millet, wheat, rice and rice, is listed as the "Six Grains". In ancient times, it was mainly planted as a food crop. Later, "Zizania latifolia" was parasitized by smut, which made it impossible for the plant to head and blossom. Instead, an abnormal and hypertrophy fungus gall was formed at the top of the stem, which was called "Zizania latifolia" in ancient times. Smut is a fungus, basidiomycete. As early as the Western Zhou Dynasty, it was found that this kind of fungus gall was fresh, tender and edible, and it was a delicious vegetable.

"Erya" records: "Deep vegetables are like soil bacteria to grass. Today, Jiangdong is sweet and slippery. " Erya was written in the Qin and Han Dynasties, so it can be seen that at that time, in addition to using English white seeds as food, Zizania latifolia was already used as food. According to the Southern Song Dynasty Luo Yuan's Er Ya Yi. "Nowadays, there are bacteria in the middle, such as children's arms, and Erya is called a vegetable." He also said: "The leader has been with Jiang for more than three years. His heart is like a lotus root, and he is like the arm of a child in autumn. The big one is called the first one, and the so-called root licking in materia medica can also be cooked or eaten raw. It may have small black bunches such as black spots, and it is called "mullet". At the end of the Tang Dynasty, rice began to be planted on a large scale in China and became the staple food of people. After that, the seeds of Zizania latifolia were rarely collected, so that it gradually separated from grains and became a vegetable with special flavor and rich nutrition, which was called carved Hu and Zizania latifolia in ancient times. Zizania latifolia has been widely planted since the Tang Dynasty, and its seeds are one of our five cereals. Later, it was found that some Zizania latifolia was infected with smut, the plants did not heading, and the stems kept expanding, gradually forming a spindle-shaped fleshy stem covered by a green leaf sheath, with three cylindrical nodes in it, yellow, white or blue-yellow, with tender meat and less fiber. Zizania latifolia is a special vegetable in China and one of the "three famous dishes in the south of the Yangtze River".
