What farm tools did farmers innovate in the Tang Dynasty? What are the characteristics of these farmers?

1. Irrigation tools: trucks. It is also called the water tumbler. The bamboo tube rotates by itself with the water flow, which can pump water from a lower place to a higher place, and can irrigate 100 mu of fields day and night, which is far more effective than turning it upside down. Since the invention of rollover irrigation in the Three Kingdoms period, it has been operated manually. In the Tang dynasty, there were pedal rollover and cattle rollover, and the effect was greatly improved. In the Tang dynasty, there was also a vertical waterwheel, also known as a well truck. This is a kind of waterwheel connected with wooden barrels, which is used to extract well water. It has been used in rural areas in the north and has played an important role in dry land agriculture.

2. Agricultural tools: Qu Yuan plough. Also known as Jiangdong Plough. Portable crankshaft plow has perfect structure, compact frame, convenient rotation, flexible operation, convenient deep ploughing and saving animal power: one cow can pull it, which has changed the previous traction mode of two cows lifting the bar. Since then, China's plow has been basically shaped. Claw appeared in the Tang Dynasty, which is not only a tool for weeding, but also can prevent nails from being worn by sand, so it can also be regarded as a tool for labor protection.

3. Land preparation tools: Luqi. Also known as "Lu Zhou", it is a cylindrical agricultural tool made of stone, with slightly larger ends and smaller ends, which is suitable for rotating around a center. Used for rolling grain, leveling the ground, etc.

4. Grain processing tool: water mill. The water mill in the Tang Dynasty was more advanced than before. Power is still started by running water. The best illustration of the development level of hydraulic stone rotary grinding in Tang Dynasty is a picture of a car at the door collected by Shanghai Museum. Judging from the proportion of the whole building complex, the water mill and the water turbine under the water mill occupy the whole central hall in the picture, which is really a behemoth. The whole scene is magnificent, the building is magnificent, and there are many service personnel, which shows how much attention was paid to this kind of water mill called "transfer car" at that time, and then the importance of water mill to society can be seen.
