Champa rice is a fast-maturing, drought-resistant variety that can be harvested every sixty days. Champa rice originates from the subpopulation that shares characteristics with both and rice varieties. Champa rice likely originated in India and was introduced to China in the late 10th century.
What was the purpose of Champa rice?
It is a very important animal feed and is used extensively in the production of the biofuel cellulosic ethanol. Asia’s staple food is rice (Oryza sativa), the second largest cereal crop.

During the Song period, innovations in rice cultivation, particularly the introduction of from what is now Central Vietnam, as well as and, dramatically increased rice yields. Rice was primarily consumed as food, but was also employed in the production of the wine consumed in homes and taverns.
- Rice was primarily cultivated south of the Yangtze River.
- This region had many advantages over the North China Plain due to its warmer climate and abundant rainfall.
- Summer and winter crops could frequently be grown on the same plot of land due to the south’s mild climate.
- The region’s numerous rivers and streams facilitated shipping, which reduced transportation costs and made regional specialization economically feasible.
Throughout the Song era, became the. As cultivated throughout East Asia prior to modernization — to level paddy fields, clear irrigation ditches, plant and especially transplant seedlings, and to weed, harvest, thresh, and hull. Farmers created, such as drought-resistant and early-ripening varieties, as well as rice suited for special applications such as brewing.
What was created during the Tang Dynasty?
Cultural Advances – Xuanzong was a poet and cultured man who supported the arts and encouraged creative expression. During the Tang Dynasty, primarily during the reign of Xuanzong, more than 50,000 poems, plays, short stories, and other literary works were composed, and an encyclopedia was also compiled.

Advances in medicine, such as recognized symptoms of a disease and how to treat it, were now available to the general public through books that also suggested preventative habits and promoted diet as a health-promoting factor. The world’s first clock mechanism was invented in 725 CE by the Chinese engineer Yi Xing, as a result of technological advancements.
- Additionally, mechanical expertise led to the creation of automatons, which were self-moving, motorized figures.
- Even though motorized puppets existed in China as early as (221-206 BCE), the automatons of the Tang Dynasty were more complex and based on designs by Hero of (circa 10-70 CE), who was renowned for his inventions in.
A motorized monk that collected donations was an example of a Tang automaton, as was a mountain-shaped wine-pourer that utilized a hydraulic pump. During the Tang Dynasty, gunpowder, waterproofing, fireproofing, gas stoves, and air conditioning were also invented.
- They created agricultural machines to expedite the planting, watering, and harvesting of crops.
- The poor, who formerly wore primarily animal skins, could now afford the linen worn by the middle class, albeit with coarser material.
- The increase in trade brought more new ideas, inventions, and products than ever before, resulting in a dramatic improvement in the quality of life of the Chinese people.
When Xuanzong began his personal decline, the entire Tang Dynasty collapsed and the country was plunged into chaos.
