The earliest edible rice in China is Zizi, and the literature about Zizi can be found in Zhouli in the 5th-3rd century BC. "Cattle should be covered with millet, sheep should be covered with millet, dogs should be covered with millet, geese should be covered with wheat, and fish should be covered with millet.
It shows that "Zizania latifolia" is a kind of grain, which is used as food, and it is listed as one of the six cereals.
During the Warring States Period, Zizania latifolia was one of the important cereal crops of China people.
However, the flowering period of Zizania latifolia is long, the maturity of seeds is inconsistent, and it is easy to fall off naturally and the yield is low, so it is no longer used as the main food crop in the future development.
The record of preserved vegetables was first found in Wang Pan's Wild Cookbook during the Jiajing period (1522-1566), saying, "Preserved vegetables are raw at the bottom of the water, and if reed shoots, they are better than rice.
I want to satisfy my hunger, and my eyes are full of tears.
Hunger Relief: Being born in Shui Ze in summer means sprouting.
Both raw and cooked.
"There are many citations in the subsequent literature.
Relatively speaking, there are not only few records about preserved vegetables in ancient books, but also late.
Up to now, Hubei Province, Jiangsu Province and other places still have the habit of eating pickled cabbage in early summer.
Potamogeton crispus can only be picked in the wild.
The consumption of Zizania latifolia was first seen in Er Ya Shi Cao, which was written in the Qin and Han Dynasties, and there was an entry of "Going out of the tunnel: crossing vegetables".
Guo Pu (257-324) of the Eastern Jin Dynasty noted: "The plants are like soil bacteria, and they grow in the grass, but now they are fragrant in the east of the river, which is sweet and smooth.
"The Biography of Hans Zhang in the Book of Jin" (648) records that during the rebellion of the Eight Kings in the Western Jin Dynasty (290-311), when Hans Zhang, a writer, was an official under Sima Tang, the king of Qi, "because of the autumn wind, he thought about Wuzhong's vegetables, soups and bass.
Here, "going out of the tunnel", "water chestnut" and "water chestnut" all refer to the present water chestnut.
Water bamboo can be divided into double-season water bamboo and single-season water bamboo.
The record of double-season Zizania latifolia was first recorded in the Tang Dynasty. In the Tang Dynasty, Han Baosheng said: "The roots of Zizania latifolia are raw in water, and the leaves are like sugarcane and glutinous rice. For a long time, the roots are thick and thick.
Xia Yue is famous for its raw bacteria.
For three years, the center is white like a lotus root, white and soft like a child's arm, and there are black veins in it. Those who are worthy of it are also named as the first.
"Here," there are black veins ",which means smut fungus.
It can be seen that the so-called "Zizania latifolia" is produced in summer, that is, "Zizania latifolia".
According to the biological habits of Zizania latifolia, those who can produce Zizania latifolia in summer should be double-season Zizania latifolia.
In the 4th year of Xianchun in the Southern Song Dynasty (1268), it was stated in the Records of Piling (now Changzhou) in Jiangsu Province that "water bamboo shoots are also born in spring", which also refers to double-season water bamboo shoots.
In the Ming Dynasty, Wang Shimao's Yu Shu in Xuepu (1587) clearly recorded the varieties of double-season water bamboo, "Water bamboo was born in autumn, and Wuzhong was born in spring, which was called Lv Gong water bamboo.
Take untimely as beauty.
The successful breeding of double-season Zizania latifolia, represented by Lv Gong Zizania latifolia, is a great achievement of ancient ancestors in China in Zizania latifolia breeding.
In fact, among the varieties of Zizania latifolia, single-season Zizania latifolia is more abundant than double-season Zizania latifolia, and it is also the main type used by the ancients for cultivation.
The above shows that the domestication and cultivation of Zizania latifolia originated in Taihu Lake area at the earliest, and people in China have not only a long history of using Zizania latifolia, but also carried out the work of variety breeding.
