What is the knowledge about agriculture?

The ancestors of corn were in America, and Columbus brought corn back from Cuba in 1492, which was a very strange plant at that time. This kind of thing is not produced in China. Some TV dramas let people hang corn cobs in their own yards during the Tang and Song Dynasties. That's nonsense. It is said that corn was introduced into China in 15 12. I'll talk about it later. There is an inference that China first discovered America, and the evidence is recorded in ancient history books. Fusang is corn. Attached is a record describing the country of Fusang.

Liang Shujuan is 54 years old.

In the first year of Qi Yongyuan, the state-owned Saman Shen Hui came to Jingzhou and said, "Fusang is more than 20,000 miles east of Dahan, and the land is east of China. Its soil is full of hibiscus wood, hence the name. " Hibiscus leaves are like tung trees, but they are as tender as bamboo shoots. People in China eat it as red as pears, and the skin is made of cloth and cotton. Make a board house without battlements. There are words, with hibiscus skin as paper. Without armor, there is no attack. Its national law has north and south prisons. If you commit a minor crime, you will go to the South Prison, and if you commit a major crime, you will go to the North Prison. If you forgive, you will forgive the southern prison, but not the northern prison. Men and women in the northern prison are paired, with boys at the age of eight as slaves and girls at the age of nine as handmaiden. Guilty people will never leave until they die.

I don't know how experts infer that "hibiscus leaves are like tung", and I don't know what similarities there are between corn leaves and tung leaves. It makes sense to say that it was born like a bamboo shoot. But some experts think that Fusang is corn, which is somewhat arbitrary. Some people think that the country of Fusang is Japan. (Later, Fusang was often called Japan. However, Japan does not exceed 20,000 miles. In the Tang Dynasty, the Japanese sent envoys to the Tang Dynasty to take the southern route by boat and arrived in China in three days. More than 20 thousand miles, so far, some people think it's America. It is even more incredible that Zheng He went to the West to reach America. I don't think this is likely to be America. First of all, hibiscus can't be corn. Then there is no mature writing system in the United States, Indians have no writing, and Mayan writing is a gobbledygook, which few people understand.

Columbus brought corn back to Spain, and Spain brought corn to the world. Spain occupied Luzon (Philippines), and probably the corn came from Luzon (accompanied by syphilis, which Fang Hung-chien reported in Fortress Besieged). According to the data, the earliest description of corn in China was in Pingliang County Records in the thirty-ninth year of Jiajing (1552). At that time, it was called Fanmai (the same name as tomato). In Li Shizhen's Compendium of Materia Medica, corn was also planted in the west, but there were few growers, indicating that there were few growers at that time. Because it is a newly introduced variety, it has a new name every time it is promoted in a place. In addition to Fanmai, Zea mays and Xitianmai (funny, brought here by Tang Priest), there are other names such as Baogu, Baogu, Liugu and Yao Lu (as for other names, you can contribute a few). It was mostly used as a non-staple food at that time. Later, because of its strong adaptability and easy cultivation, spring corn matured earlier than other spring sowing plants, and it was easy to make up for the shortage when it was green and yellow, and soon became the rations of farmers in mountainous areas, and then gradually spread to the plain areas. Since the 1950s, corn planting has developed greatly, surpassing chestnut to become the third largest food crop (the first two are rice and wheat).

Nowadays, corn is mostly used as feed, and of course, new varieties of edible corn such as sweet corn have been developed. I would like to ask how corn is eaten in many parts of the world, especially Mexico (the hometown of corn). Another important part of corn is making popcorn. The United States in 1930s was the era of popcorn and movies. Watching movies and eating popcorn was a fashion at that time.

Of course, corn can also be used to make wine, and many places in mountainous areas use corn to make wine. Corn wine is very good in some places in western Hubei.

Someone mentioned the era of eating corn flour. No one had eaten corn flour at that time. At that time, coarse grains accounted for 60% and coarse grains accounted for 40% in some places. Corn left a deep influence on people of that era.

Wowotou, also known as Wowotou, was the staple food variety of working people in the past. It is steamed with corn flour and a small amount of "screwdriver" (that is, baking soda) or alkali, so it is named because there is a concave pit at the bottom. Steamed dates are called jujube steamed buns, those with brown sugar are called sugar steamed buns, and those with onion and salt are called salty steamed buns. In the past, ordinary people could only eat a few white-flour steamed buns during the Spring Festival or the wheat harvest season, and generally they had to eat steamed buns. Of course, some people occasionally eat corn buns for a change. Now the supermarket also sells corn buns. Strictly speaking, it's not called corn buns, because there is no nest, and it doesn't taste so rough with wheat flour. Steamed bread used to be rough, but the more you chew it, the harder it is to swallow. Mr. Lao She grew up eating steamed buns, so his works are close to the people. In contrast, Xu Zhimo, Lin Yutang and Hu Shi are vulgar.

6 1 62, when food was difficult, our hometown people steamed corn with bran (the skin left after grinding wheat is now generally used to feed pigs) and radish, but because it was not sticky, they had to knead it into a ball. That's it. These are all good things. At that time, people there ate everything, such as bark, grass roots and corn leaves ... but they didn't eat people.
