Stock history

Around 3500 BC, farmers in the Mesopotamian plain invented the ox-pulling plough. Plow is an agricultural tool that people began to cultivate land in the early days. People in China have used plows, wooden plows and stone plows since the Shang Dynasty. In 500 BC, European farmers built an iron plow with two wheels and a share in front. During the Warring States Period, China put a V-shaped iron shovel on the wooden shovel, commonly known as the iron mouth plow. The plough frame is smaller, lighter, more flexible and adjustable in depth, which greatly improves the farming efficiency. In A.D. 1700, Europeans began to use advanced Roslin plows, Ransom iron plows and seeders. 1830, American immigrants began to use Deere copper plow, and other continents also began to use copper plow. In a word, the invention, application and development of plough condensed the efforts of China people and other inventors in the world, and showed their wisdom.
