As an ancient traditional crop, red dragonfly is suitable for planting in mountainous areas because of its unique biological habits. The area where red dragonfly is planted in history is only the southwest mountainous area of ​​China, mainly in the Xishui area. Xishui is located in the northern part of Guizhou. It is the junction of Sichuan and Chongqing, and the Chishui River passes through the county. Since ancient times, it has been a trading center and a good wine. The place where the wine is produced is indispensable to the cereal grains. Therefore, Xishui is a large grain-growing county, which complements the local wine industry. In this context, Hung Hom was widely planted in Xishui due to its unique taste and nutritional value, and developed rapidly to a certain scale. Eventually, the name “Xi Shuihong” was formed by word of mouth.

Red peony is rich in 17 kinds of amino acids beneficial to human body: aspartic acid, threonine, serine, glutamic acid, glycine, alanine, cystine, proline, methionine, isoleucine, leucine Acid, phenylalanine, tyrosine, histidine, lysine, arginine, proline; vitamins B1, B2, B3; mineral trace elements: potassium, sodium, calcium, magnesium, iron, selenium Human essential nutrients such as protein, dietary fiber, carbohydrates, etc. According to the records of Minnan Materia Medica, red peony is a kind of ancient original ecological crop with the same origin of medicine and food. It has been planted in Zunyi in 1610, and it is born in cold soil of plateau mountainous area above 1500 meters above sea level. It is drought tolerant and less Diseases, Qing Emperor Qianlong, Jiaqing years of extensive breeding. Function Indications Root: Tiaojing Stops bleeding. For nasal discharge, blood in the stool, menorrhagia, postpartum hemorrhage, etc. Seed: rash and cough, make up the water. For measles, chickenpox, whooping cough, rectal prolapse, edema. The whole grass has both the root and the seed. The relationship between Xishuihong and the natural factors of the production area 1. Xishui is located in the high-altitude mountainous area, and the unique mountainous terrain is suitable for the growth of red carp, providing a specific growth environment for the growth of red carp. The wide distribution of sandy loam is one of the necessary conditions for the production of high quality red peony. Xishui County is located in the north of Guizhou Plateau, which is continuously rising in the near future. Xishui belongs to Dagu Mountain and Chishui River Basin. The whole county is mainly based on plateau mountainous terrain, with high altitude. The county has an elevation of 275m-1871.9m. The sandy loam is widely distributed. The territory of Xishui County is conducive to the growth of red dragonfly. The temperature difference between day and night at high altitude in this area is large, which improves the photosynthesis efficiency of red peony and is conducive to the accumulation of red sorghum. At high altitudes, the content of soluble carbohydrates in red sorghum plants is high, and the illumination time is long. The light (solar radiation) is the only energy source for all metabolic activities of red carp. In the high-altitude mountainous areas with special features, Xishuihong has “plateau, green, organic "specialty. Because Xishuishan has fewer fields, it is the most inferior. If there is a little rain, there will be sufficient rain in the high slope area, and there will be disasters in the low area. If the drought is less rainy, the irrigation in the low area is quite sufficient, and the high slope area is also very dry, red. It is the special product formed under this geographical condition. Because its red carp has the growth habit of being poor and resistant to water and fertilizer, it is suitable for the development of mountain agriculture. 2, Xishui warm and humid climate, provide good climatic conditions for the growth of red carp, the county is wet, foggy, high temperature and low cool, suitable for the growth of red peony. Xishui County has a subtropical mountain climate. The average annual sunshine hours of the county is 1053.0 hours, the annual average temperature is 13.5 °C, and the annual average frost-free period is 268 days. It is wet and foggy, high temperature and low temperature, and frequent changes. The spring is low and cool, the summer is rainy; the autumn is cool; the winter is damp, the local microclimate is obvious, and the vertical difference in climate is significant. It is the ideal environment for the growth of red dragonfly. The growth of red peony requires a suitable climatic environment. The excellent climatic environment of Xishui County provides a guarantee for the production of high-quality red peony. The light is sufficient to promote the photosynthesis of red peony and accelerate its growth. It is also conducive to the precipitation of nutrients of red peony. Temperature, which promotes the metabolism of red peony, is a necessary condition for the growth of red sorghum. Xishui County is rich in rainfall and provides sufficient irrigation water for the growth of red carp. The superior climatic resources of Xishui are favorable conditions for the growth of red sorghum and also form The unique characteristics of Hung Hom also make Xishui Hung Hom popular with consumers and its popularity is constantly improving. Gradually sold to all parts of the country and even foreign cities.

Quality technical requirements of Xishuihong稗 I. Carex baccans Nees, the source of the genus Cypress, and the elevation of 800m to 1600m in the site of the site.
