The hometown of Shajiang in China-Nansheng in China

[Edit this paragraph]

Ginger is panicum miliaceum, which is drought-resistant, 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 are just suitable for planting galangal. The galangal produced by Nansheng is of the highest quality. Its galangal is brown, slightly shiny, and has a thin skin and thick flesh, crisp and tender meat, spicy and sweet taste. It has the effects of eliminating phlegm and promoting circulation, promoting digestion and appetizing, invigorating spleen, eliminating water and removing dampness, and preventing epidemic. According to the legend of the elders, during the Guangxu period of the Qing Dynasty, plague was prevalent in Huazhou and neighboring counties, and villagers in Nansheng area ate ginger to prevent them from getting immune diseases, which made the surrounding areas peaceful. In addition, Nansheng Shuijiang is accompanied by the local famous dish "White Cut Chicken", which is fragrant but not greasy and full of flavor. Restaurants, restaurants and residents' families all use ginger as the main seasoning, and they become accustomed to each other. There is also spice powder used by local chefs for seasoning, and most of them are served with ginger in the south. The dishes are particularly delicious.

Nansheng has a history of more than 200 years of planting Shajiang, and it was only a few tens of acres at that time. Since then, the application of Alpinia officinarum has become more and more extensive. 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 continuously expanded, and it has developed to more than 500 mu in the late Qing Dynasty. During the Republic of China. The planting area of xie cun, Shanwei and Letang has been expanded from Pushan to Nansheng, with an annual planting area of more than 1,000 mu of ginger. During the listing season of Shajiang (dried ginger slices), many merchants in Nanshengwei buy them by the scale and ship 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 acquisitions, 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 the Nansheng Water Diversion Project, there were many waterlogged fields in summer, which was not conducive to the production of Alpinia officinarum. In addition, there was a tendency of "paying more attention to grain than money" at that time, so that the planting area of Alpinia officinarum decreased. 1988 The whole region (town) planted about 200 mu of ginger, with a total output of more than 300 tons.
