The history and development of rice in China, who invented rice?

Origin: From the perspective of species distribution, about 50,000 years ago, early rice plants appeared in Yunnan. Therefore, it is speculated that the earliest area of rice cultivation in Asia should be the Yunnan region.

Archaeological discoveries in Hunan Dao County and Jiangxi Wannian County show that humans began to cultivate and eat about 13,000 years ago, and humans should have chewed whole rice grains by mouth before the Neolithic period.

There is evidence of rice cultivation in the Hemudu site excavated in the lower reaches of the Yangtze River. As early as 7,000 years ago, the original inhabitants of the lower reaches of the Yangtze River in China had fully mastered the cultivation technology of rice and took rice as the main food.

The Hemudu culture in the middle and lower reaches of the Yangtze River entered the Neolithic Age after about 7,000 years.

The invention of the pestle mortar was applied, and mankind knew how to clean and separate the uneaten chaff and rice bran. Soon thereafter, it should be found that washing with water is a more efficient process of removing impurities and cleaning the rice, and the efficient debacterization and removal of oxidized bran layer and dust in the rice washing process are still in use, and the pestle and mortar rice making equipment is still used until the seventies of the twentieth century.

In the 19th century, the unrolled rice machine was invented, and the efficiency of rice milling was greatly improved. In the mid-twentieth century, the blast rice machine came out, and the rice milling effect was greatly improved.

In the late twentieth century, the rapid development of rice-making technology, the continuous improvement of the level of automatic cleaning of photoelectric color sorting, coupled with the continuous expansion of japonica rice planting in the cold regions of the north, in 1988, the rice-free rice was produced on a large scale in the second rice factory of the Grain Bureau of Daqing City, Heilongjiang Province. In 1989, the 50-ton-day production line was launched.

In the ruins of the Yellow River Basin, as early as 5,000 years ago, China was a country that cultivated rice, and later the rice in the Jiangnan region could feed the population of the whole country.

As a great ancient civilization, China has a long history of cultivating rice and wheat, and since the founding of the People's Republic of China, it has been vigorously supporting agricultural development and making great achievements in scientific research, which has been highly praised by the international community.

What about the daimyo of China? At that time, was it in ancient times, when the Hemudu clan was in power? Mainly rice is grown.

China believes that rice originated in China, and rice plants appeared in Yunnan 50,000 years ago. It was found at the Hemudu site that 7,000 years ago China had a history of rice planting.

Five grains of carbonized rice were found in Yuchanyan, Daoxian County, Hunan Province, which was 12,000 years ago and was known as the oldest rice in the world.

12,000 years ago, rice became a staple food for Chinese.

It should be said that it is a discovery, not an invention.

Rice, commonly known as rice. The origin of rice remains a long-standing topic of debate in the scientific community. Scientists debate the time, place, and origin of the first batch of rice.

The cultivation of rice originated in the settlement zone of the middle reaches of the Pearl River in Nanzhong about 8200 B.C., and archaeological discoveries also found that there was also an early rice in Hunan before about 8200 B.C. In 1993, the archaeological team discovered the world's earliest ancient cultivated rice in Yuchanyan, Daoxian County, about 8,200 years ago.

After rice is widely cultivated in China, China and east, south and Asia, it gradually spread westward to India and degree, and has been the staple food since ancient times in the Asian monsoon climate zone, and was introduced to Europe and southern Europe in the Middle Ages. At present, half of the world's population eats rice, mainly in Asia, Europe, southern Europe and parts of tropical America, Africa and Africa. Total rice production in 2013 was the second largest in the world for food crops, only below maize.

Shennong was the first person to be recorded as eating rice. Shennong's way of eating is to heat the stones, put the rice directly on the stones to heat, and make it cooked. Nowadays, Shanxi's famous stone cake still uses this ancient cooking method.

The conditions of the pre-Qin were simple, so the rice could only be boiled in a pot, and then taken out and steamed in a steamer until it was half-cooked.

During the Qin and Han dynasties, rice was called "dry rice", which was dried in the sun and then sealed and stored. When eating, put in soup and eat as you like, a bit like today's instant cereal, which is easy to carry and anti-hunger.

During the Wei, Jin, Southern and Northern Dynasties, people ate more and more types of rice, but the output was too small, so everyone would mix various vegetables into the rice to make "vegetable rice", just like today's fried rice.

Rice is not an invention, rice originates from wild rice, which has existed in nature for a long time and has been domesticated by humans for tens of thousands of years to become one of the staple foods. The latest archaeological research proves that humans learned to grow and eat about 13,000 years ago.

Rice and rice have been around since ancient times, and they are not something invented by one person. Hybrid rice is an improved variety by Yuan Longping.

<> the world's rice originated in China, as early as 7,000 years ago, the original inhabitants of the lower reaches of the Yangtze River in China have completely mastered the cultivation technology of rice, and take rice as the main food. After rice was popularized and planted in China, it soon spread to neighboring countries in East Asia. About 3,000 years ago, at the turn of Yin Zhou, China's rice spread from the Zhoushan Islands to North Korea, Japan, and Vietnam.

During the Han Dynasty, Chinese rice was introduced to the Philippines. In the 5th century AD, rice spread to Western Asia via Iran and then to Europe via Africa. After the discovery of the New World, it spread from Africa to the Americas and the world.

In 1990, the national rice output was 170200000000000 catties, and the number of mu was 100 million mu。In the early nineties, the yield of rice per mu was about 800 catties. Yuan Longping.

In the nineties, the development of Zayouyou rice cave Bosen was successful, so that the yield of rice per mu reached 1300 catties and 1 mu.

China is one of the first countries in the world to plant rice, as early as six or seven thousand years ago, the Hemudu clan in the middle and lower reaches of the Yangtze River began to plant. During the Song and Song dynasties, Champa rice was introduced from Vietnam, which was both drought-resistant and high-yielding. It has been rapidly promoted, and since the Song Dynasty, rice production has jumped to the first place among grain crops and has become the staple food of the Chinese.

Nutritional value of rice

Rice contains carbohydrates.

75% or so, protein 7%-8%, fat to 18% and rich in B vitamins.

Wait. The silver carbohydrates in rice are mainly starch, and the protein contained in rice gluten is mainly rice glutenin, followed by rice gum and globulin, and the biovalence and amino acids of its proteins.

The proportion of composition is higher than that of wheat, barley, millet, corn and other cereal crops.

Lysine in rice protein.

and threonine content is less, so it is a complete protein, and its nutritional value is not as good as animal protein. However, eating rice at lunch and dinner is more beneficial than pasta**. In the southern part of our country.

People generally eat rice as a staple food, but in the north it is very different.

The fat content is about 1% to 10%, and the linoleic acid content in the fat is relatively high, generally accounting for 34% of the total fat, which is 2 to 5 times more than rapeseed oil and tea oil respectively.

The inventor of rice is not known for sure, but archaeological information suggests that rice was first cultivated by Chinese ancestors dating back more than 13,000 years.

In addition to Antarctica, rice is grown on all continents of the world, with 21 different wild varieties and 3 different cultivars. So far, the oldest evidence of rice consumption is a four-grain rice found from the Yucia Cave in Dao County, Hunan Province, China. Some scholars associated with the site believe that the grains appear to represent an early form of domestication, with japonica and alfalfa characteristics, and are dated to about 13,000 years ago.

Hehe, this question, rice is made from rice after artificial processing, and the wheat is processed into wheat, and then milled out of white flour. In the south, two-crop rice is generally grown, and in some places it is three-crop rice, and two-crop rice extends from south to north to Taierzhuang in Shandong, and then grows wheat in the north. There is a crop of rice in the northeast (basically in Heilongjiang).

In fact, the rice we eat in daily life is finely processed, so some of the nutritious parts have been removed, and eating some coarse grains regularly is very beneficial to the body

Nobody invented, it was discovered! As for hybrid rice, it was cultivated by Yuan Longping, and this achievement has greatly increased China's rice production. So let's have white fat millet grains to eat.

It was discovered by the people of Hemudu in the Neolithic period, when they planted rice, and rice is rice.
