Moxibustion, the name of agricultural tools of the old Han nationality. It is a kind of animal-powered drill. Zhao Guo worked as a cymbal in the Western Han Dynasty, with a history of more than 2, years. It is composed of a hammer frame, a hammer bucket, a hammer leg and a hammer shovel. There are many kinds of one-legged cymbals to seven-legged cymbals, and the sowing of two-legged cymbals is more uniform. It can sow barley, wheat, soybean, sorghum and so on. The first seed drill in the west was inspired by China. In 1566, the Venetian Senate granted the patent right to the earliest drill in Europe, and its inventor was Camiro Torello. The earliest drill that left a detailed explanation was that of Tatier Ka Varina in Bologna in 162, but it was very primitive. The first real drill in Europe was developed in Jethro Tull. Shortly after 17, this machine was produced, and its description was published in 1731. But this and other types of drill rigs in Europe are expensive and unreliable. It was not until the mid-19th century that there were enough solid and good quality drill rigs in Europe.
those who don't know the history of western agriculture may be surprised to learn that there was no drill until the 16th century. Before the drill was used in the west, seeds were planted by hand. This is a great waste, and often half of the grain harvested in the current year is reserved for sowing in the next year. When the seeds used for sowing are germinated and grow into plants, everyone gathers together to compete for water, sunshine and nutrition, and there is still an unsolved problem that weeding cannot be done.
