The first complete agricultural book that exists in our country is

The earliest surviving complete agricultural book in China is the "Qi Min Yao Shu" written by Jia Sixian, an agronomist in the Northern Wei Dynasty.

Qi Min Yao Shu is a comprehensive agricultural book, the first of the five major agricultural books in ancient China, which describes the agricultural production in the lower reaches of the Yellow River Basin, that is, the southeastern part of present-day Shanxi, the south-central part of Hebei, the northeastern part of Henan, and the north-central part of Shandong, and outlines the production technology knowledge of agriculture, forestry, animal husbandry, fishery, and sideline departments.

Jia Siqian believed that the level of agricultural science and technology was related to whether the country was rich and strong, so he came up with the idea of writing a book on agriculture. During his time as an official, he traveled to many places. Everywhere he went, he attached great importance to agricultural production, and he used to personally engage in agricultural production practices, conduct various experiments, raise livestock, and grow grain.

It not only pays attention to hands-on practice, but also is good at learning from experienced old farmers, and absorbs the valuable experience summed up by working people in long-term production and life.

Finally, on the basis of summarizing the experience of predecessors, combined with the production knowledge obtained from experienced old farmers and the personal practice and experience of agricultural production, he carefully analyzed, systematically sorted, summarized and summarized, and finally completed the "Qi Min Yao Shu".

The influence of the later generations of "Qi Min Yaoshu":

Qi Min Yao Shu can be interpreted as a method of livelihood for civilians, and it can also be interpreted as a method of governing people's livelihood. Since the Tang and Song dynasties, there have been many agricultural books, all of which take it as a model, among them, Yuan's "Agricultural Mulberry Collection", Wang Zhen's "Agricultural Book", Xu Guangqi's "Complete Book of Agricultural Administration" in the Ming Dynasty, and the Qing Dynasty's "General Examination of Time" are all influenced by it.

Qi Min Yaoshu systematically summarized the knowledge of agricultural science and technology in the Yellow River Basin of China since the Qin and Han dynasties, preserved the essence of agricultural technology in the Han Dynasty, and focused on summarizing the new experience and achievements of dryland agriculture in northern China after the Book of Bisheng, and in the following 1,000 years, the development of dryland agricultural technology in northern China basically did not exceed the direction and scope of its summary, and opened up a way to follow for many agricultural books in China later.

The earliest surviving complete agricultural book in China is the "Qi Min Yaoshu" written by Jia Siqian of the Northern Dynasty.

The book summarizes the production technologies of agriculture, forestry, animal husbandry, sideline products, and fishery, and is very rich in content. Jia Siqian sorted out the agricultural knowledge recorded in ancient books, collected folk songs and proverbs, and learned from the production experience of farmers.

He also proved and enriched these experiences in production practice, emphasizing that agricultural production should follow the laws of nature, and that crops must be planted according to local conditions.

Qi Min Yao Shu praised Geng Shouchang's Chang Ping and Sang Hongyang's average loss method as "the art of benefiting the country and the people, immortality", and ridiculed Confucius for "not being diligent in the four bodies, and not dividing the five grains".

Jia Siyun has established a relatively complete agricultural science system, and has made a reasonable classification of agricultural categories characterized by practicality. A series of processes such as land reclamation, cultivation, post-production processing, brewing, and utilization are described in detail, and also discuss planting, forestry, and various aquacultures.

The first complete agricultural book in China is "Qi Min Yaoshu". Qi Min Yaoshu is a comprehensive agricultural book, the first of the five major agricultural books in ancient China, which describes the agricultural production in the lower reaches of the Yellow River Basin, that is, the southeastern part of present-day Shanxi, the south-central part of Hebei, the northeastern part of Henan, and the north-central part of Shandong, and covers the production technology knowledge of agriculture, forestry, animal husbandry, fishery, and sideline departments.

Qi Min Yao Shu was written in the last years of the Northern Wei Dynasty (533-544 AD), which is a comprehensive agricultural work written by Jia Sixian, an outstanding Chinese agronomist during the Northern Wei Dynasty and the Song to Liang dynasties in the Southern Dynasties, and is also one of the earliest monographs in the history of agriculture in the world, and the earliest complete agricultural book in China.

The book consists of 10 volumes and 92 articles, systematically summarizing the agricultural and animal husbandry production experience, food processing and storage, utilization of wild plants, and methods of controlling famine among the working people in the middle and lower reaches of the Yellow River before the sixth century, and introduces in detail the seasons, climate, and the relationship between different soils and different crops, and is known as the "Encyclopedia of Ancient Chinese Agriculture".

Other agricultural books in our country:

1. "Agricultural Mulberry Compendium".

The book consists of 7 volumes and more than 60,000 words, mainly introducing the agricultural technology of the north. Although much of the content in the "Compendium of Nongsang" is quoted from ancient agricultural books such as "Qi Min Yaoshu", there are also new contents, and they are more practical.

2. "Wang Zhennongshu".

Wang Zhen's Book of Agriculture was written in the second year of Emperor Yuanrenzong's reign (1313), and the author was Wang Zhen (year of birth and death unknown). The book has a total of 130,000 words, which changes the limitations of the previous agricultural books that describe agriculture in the north, and discusses the agricultural technology and its similarities and differences between the north and the south, and at the same time widely introduces various agricultural tools in the first way.

3. The Complete Book of Agricultural Administration

Written in the seventh year of Qianlong in the Qing Dynasty (1742), it is a comprehensive agricultural book officially revised in the middle of the Qing Dynasty. The book has a total of 78 volumes and more than 980,000 words, with field production as the main content, as well as various industries of forestry, animal husbandry and sideline fishery. In addition to compiling the agricultural books of the past dynasties, the "General Examination of Conferral of Time" also widely quoted many words and illustrations about agricultural affairs in the "Siku Quanshu", and the literature value is very high.

The earliest and most complete agricultural book in China is "Qi Min Yaoshu".

Qi Min Yao Shu is a comprehensive agricultural work written by Jia Sixian, an outstanding Chinese agronomist during the Northern Wei Dynasty and the Song to Liang dynasties in the Southern Dynasties, and is also one of the earliest monographs in the history of agriculture in the world, and is the earliest complete agricultural book in China. The book systematically preserves the essence of ancient agricultural technology, summarizes the agricultural production experience of more than 400 years in the Wei and Jin dynasties, and is the earliest, most complete and most comprehensive and valuable ancient agricultural work in the world.

Qi Min Yao Shu is regarded as a symbol of China's ancient agricultural system, and is also known as "the encyclopedia of ancient Chinese agriculture".
