Louche Effect Grapefruit-cello
Louche () was a mobile animal-drawn agricultural seed drill invented by the Chinese agronomist Zhao Guo, a Han official in charge of agricultural production during the reign of Han Wudi in the Han dynasty (156 – 29 March 87 BC). According to the records of ''Political Commentator'' by the Eastern Han dynasty writer Cui Shi Cui Shi (崔湜; 671–713), courtesy name Chenglan (澄瀾), was a Chinese writer and politician. He served as an official of the Chinese Tang Dynasty and Wu Zetian's Zhou Dynasty, serving as a chancellor during the reigns of Wu Zetian's sons ..., the Louche consisted of three feet and thus was called three-legged Lou. The three legs had three ditch diggers under it used for sowing. The Louche was animal powered and was pulled by an ox and the leg of the Louche directly dug a ditch in the flattened soil, sowed the seeds, covered the seeds, and pressed the land flat at the same time. The machine was known for its utility and efficiency for serving several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed Drill
A seed drill is a device used in agriculture that sows seeds for crops by positioning them in the soil and burying them to a specific depth while being dragged by a tractor. This ensures that seeds will be distributed evenly. The seed drill sows the seeds at the proper seeding rate and depth, ensuring that the seeds are covered by soil. This saves them from being eaten by birds and animals, or being dried up due to exposure to the sun. With seed drill machines, seeds are distributed in rows; this allows plants to get sufficient sunlight, nutrients, and water from the soil. Before the introduction of the seed drill, most seeds were planted by hand broadcasting, an imprecise and wasteful process with a poor distribution of seeds and low productivity. Use of a seed drill can improve the ratio of crop yield (seeds harvested per seed planted) by as much as nine times. The use of seed drill saves time and labor. Some machines for metering out seeds for planting are called planters. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Han Wudi
Emperor Wu of Han (156 – 29 March 87BC), formally enshrined as Emperor Wu the Filial (), born Liu Che (劉徹) and courtesy name Tong (通), was the seventh emperor of the Han dynasty of ancient China, ruling from 141 to 87 BC. His reign lasted 54 years – a record not broken until the reign of the Kangxi Emperor more than 1,800 years later and remains the record for ethnic Chinese emperors. His reign resulted in a vast expansion of geopolitical influence for the Chinese civilization, and the development of a strong centralized state via governmental policies, economical reorganization and promotion of a hybrid Legalist–Confucian doctrine. In the field of historical social and cultural studies, Emperor Wu is known for his religious innovations and patronage of the poetic and musical arts, including development of the Imperial Music Bureau into a prestigious entity. It was also during his reign that cultural contact with western Eurasia was greatly increased, directly and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Agriculture In China
For millennia, agriculture has played an important role in the Chinese economy and society. By the time the People's Republic of China was established in 1949, virtually all arable land was under cultivation; irrigation and drainage systems constructed centuries earlier and intensive farming practices already produced relatively high yields. But little prime virgin land was available to support population growth and economic development. However, after a decline in production as a result of the Great Leap Forward (1958–60), agricultural reforms implemented in the 1980s increased yields and promised even greater future production from existing cultivated land. History before 1949 Ancient history Wheat likely "appeared in the lower Yellow River around 2600 Before Common Era (BCE), followed by Gansu and Xinjiang around 1900 BCE and finally occurred in the middle Yellow River and Tibet regions by 1600 BCE". Ming era, 1368 to 1644 A.D. The population doubled as new lands wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Machinery
Agricultural machinery relates to the mechanical structures and devices used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. History The Industrial Revolution With the coming of the Industrial Revolution and the development of more complicated machines, farming methods took a great leap forward. Instead of harvesting grain by hand with a sharp blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads and stalks. The first tractors appeared in the late 19th century. Steam power Power for agricultural machinery was originally supplie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Inventions
China has been the source of many innovations, scientific discoveries and inventions. This includes the ''Four Great Inventions'': papermaking, the compass, gunpowder, and printing (both woodblock and movable type). The list below contains these and other inventions in ancient and modern China attested by archaeological or historical evidence, excluding prehistoric inventions of Neolithic and early Bronze Age China. The historical region now known as China experienced a history involving mechanics, hydraulics and mathematics applied to horology, metallurgy, astronomy, agriculture, engineering, music theory, craftsmanship, naval architecture and warfare. Use of the plow during the Neolithic period Longshan culture (c. 3000–c. 2000 BC) allowed for high agricultural production yields and rise of Chinese civilization during the Shang Dynasty (c. 1600–c. 1050 BC). Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
