In addition to rich trace elements such as selenium, iron, zinc, calcium and magnesium, as well as plant proteins and vegetable fats, the red rice is also rich in B1, B2, B6 and other vitamins and 18 essential amino acids. The comprehensive nutritional value is far better than the Thai fragrant rice.

Hunan Xinhuangyu Tibetan Red Rice Planting System is located in Xinhuang Dong Autonomous County, Huaihua City, Hunan Province, China. It is the historical heritage of farming civilization in Xinhuang Township for thousands of years. Red rice is a precious and rare species resource. For thousands of years, the Tibetan red rice has been preserved in Xinhuangyu Township, Huaihua, Hunan Province, the birthplace of hybrid rice, with its unique human geography and cultivation practices. The red rice is not only the food of the family, but also the spiritual pillar of the family's advocating nature. It is regarded as a god by the family, and has a folk culture such as witchcraft culture, sacrifice culture, birth culture, song and dance culture, festival culture, etc. close relationship. On the mountain, the mountains are closed for afforestation, and the water is irrigated under the mountain. The forest and rice are mutually complementary. The circulatory system of water and drought rotation not only enriches the planting structure of crops, but also improves the nutrient composition of the soil. The organic combination of the planting system and the fish farming duck system has invisibly established a virtuous cycle of agro-ecological system. The Xinhuangzang Tibetan Red Rice Planting System has a history of 8,000 years. Today, with the increasing influence of modern agricultural technology, the preservation of abundant rice resources not only has a positive effect on enriching China's rice genetic resources, rice production, variety improvement, rice research and ecological security, but also solving the future of mankind. Material security for food security. In addition to rich trace elements such as selenium, iron, zinc, calcium and magnesium, as well as plant proteins and vegetable fats, the red rice is also rich in B1, B2, B6 and other vitamins and 18 essential amino acids. The comprehensive nutritional value is far better than the Thai fragrant rice. At present, due to lack of understanding, lack of policies, sharp decline in rural labor, coupled with the impact of urbanization and industrialization and the comprehensive promotion of high-quality hybrid rice, the use of modern agricultural technologies such as fertilizers and pesticides, etc., the red rice planting system The inheritance and development of the company face great challenges. In recent years, the government has focused on protecting the red rice planting system through measures such as the establishment of core protected areas, and strives to make the farmers in the protected areas fully benefit, while the red rice cultivation and red rice culture are further inherited and protected. And development and utilization.
