What is generally believed to be the earliest agricultural science book in China's history?

It is generally believed that it is the earliest agricultural scientific work in the history of our country, and it is Taisheng Book. As early as the Warring States Period, there were agricultural books such as Shennong 20 and Yelao 17 in China, but these books have long been lost. Bi Sheng was written in the Western Han Dynasty. It is the earliest existing agricultural book in China, and is generally considered as the earliest agricultural book in the world.

This book about great victories is not comprehensive. About the Song Dynasty, this book has been lost. Fortunately, some books before the Song Dynasty quoted some contents of Taisheng Book, and later generations refined the materials cited in these books and compiled them into integrated books. The Book of Ascension is about 3,500 words.

In order to sum up and popularize fresh experiences among the masses, Pei Shengzhi often visited the Guanzhong Plain incognito, humbly consulted agricultural experts, and combined the agricultural experience of the masses with his own research results.

He deeply studied the cultivation techniques of rice, sericulture, wheat, melons and other crops in the north, and summarized and popularized the methods of planting wheat, sowing, selecting ears, planting melons, adjusting the water temperature in rice fields, preserving moisture and cutting mulberry seedlings, which promoted the development of agricultural production. He recorded all these valuable experiences summed up in practice in the book Great Victory.
