Rong'an Chinese Yam

Rong'an Chinese Yam

　　Chinese yam, commonly known as "shanyao," is recorded in *Compendium of Materia Medica* as having various health benefits such as "nourishing kidney qi, strengthening muscles and bones, improving digestion, stopping diarrhea, resolving phlegm, moisturizing skin and hair, and treating seminal emission and forgetfulness." It is considered a premium health food and traditional Chinese medicinal ingredient. Rong'an Chinese yam has an excellent appearance—regularly shaped, round, straight, plump, and smooth. It is of high quality, with a sweet taste, delicate and smooth flesh, a fragrant aroma, and rich nutrition, making it a top-grade variety for culinary use. Currently, our county has registered Chinese yam brands such as "Gen Zhuangyuan" (Root Champion).

　　Rong'an County is located in northern Guangxi, within the mid-subtropical monsoon climate zone. It enjoys strong solar radiation, mild weather, and abundant rainfall, with an average annual temperature of 19.0°C, average annual rainfall of 1,942.5 mm, and a frost-free period of 295 days. The climatic conditions are highly suitable for Chinese yam cultivation, and the alluvial soil along the Rong River provides particularly fertile ground. The cultivation of Chinese yam in Rong'an has a long history, reportedly starting over 60 years ago. In recent years, the planting area of Chinese yam along the Rong River has remained stable at around 10,000 mu annually. The harvesting season for Rong'an Chinese yam runs from November to March each year.

　　After several years of exploration and practice, Rong'an Chinese yam growers have mastered a set of proud technical improvements, producing yams with an attractive appearance and excellent quality. Agricultural authorities have also guided farmers in strengthening the management of Chinese yam cultivation, encouraging the use of agricultural, biological, and physical pest control methods. When pesticides are necessary, only non-toxic, low-residue varieties are used to ensure the quality of the yams.
