[Edit this paragraph] China Jiang Sha's hometown-China Nansheng Jiangsha Millet is drought-tolerant, barren and afraid of soaking. Most cultivated land in Nansheng belongs to black mud field, which is rich in carbon, soft and hydrophobic and suitable for the growth of Alpinia officinarum. Nansheng is located in the south of China and belongs to Huazhou City, Guangdong Province. The natural climate and weather here are just right for planting galangal. The quality of galangal produced by Nansheng is the best. Its galangal is brown and slightly shiny, with the characteristics of thin skin and thick meat, crispy meat and tender meat, and spicy and sweet taste. Has the effects of resolving phlegm, promoting blood circulation, promoting digestion, stimulating appetite, invigorating spleen, promoting diuresis, eliminating dampness and preventing epidemic. According to elders' legend, during Guangxu period of Qing Dynasty, the plague was prevalent in Huazhou and neighboring counties, and villagers in Nansheng area ate ginger to prevent immune diseases and make the surrounding area peaceful. In addition, Nansheng Jiang Shui is served with the local famous dish "White Cut Chicken", which is fragrant but not greasy and full of flavor. Restaurants, restaurants and families all use ginger as the main seasoning, and they are used to each other. There is also spice powder used by local chefs for seasoning, and more ginger in the south. The food is particularly delicious. Jiang Sha has been planted in Nansheng for more than 200 years, when it was only a few tens of acres. Since then, Alpinia officinarum has been widely used. Not only can it be used as seasoning, but also can be used as medicine for treating Han disease, so the planting area has been expanding, and it has developed to more than 500 mu by the end of Qing Dynasty. During the Republic of China. The planting area of xie cun, Shanwei and Tang Le has been expanded from Pushan to Nansheng, with the annual planting of ginger 1000 mu. During the listing season of Jiang Sha (dried ginger slices), many merchants in Nanshengwei bought by the scale and shipped them to Guangxi, Yunnan, Central China and North China for sale. After the founding of New China, the people's government attached great importance to the production of Alpinia officinarum, summed up and exchanged experience in planting ginger, and popularized the improved varieties of Alpinia officinarum. At the same time, the commercial department set up some purchasing points, which promoted the development of Alpinia officinarum. From the late 1950s to the early 1960s, the whole commune planted about 3,000 mu of Alpinia officinarum every year, with a yield of 2 tons per mu. Later, with the construction and improvement of Nansheng water diversion project, there were many waterlogged fields in summer, which was not conducive to the production of Alpinia officinarum. Coupled with the tendency of "valuing grain over money" at that time, the planting area of Alpinia officinarum was reduced. 1988, about 200 mu of ginger is planted in the whole region (town), with a total output of more than 300 tons.
