从八粒种子到万亩良田，文登以土壤改良与冻干技术赋能西洋参产业

Core Viewpoint - The article highlights the remarkable development of the Wending American ginseng industry, showcasing its transformation from a small-scale trial in the 1980s to a leading global producer, with significant contributions to local economy and agricultural innovation [1][10]. Group 1: Historical Development - The journey began in the late 1970s when a veteran, Wang Wenshui, sought to improve the living conditions of his impoverished village by cultivating American ginseng, starting with just 11 seeds [2]. - The first successful cultivation occurred in 1981, making the village the only successful trial site in Shandong province at that time [2]. - By the late 1980s, the region had developed comprehensive techniques for ginseng cultivation, leading to large-scale farming and breaking the monopoly held by Western countries [3]. Group 2: Quality and Environmental Factors - Wending ginseng benefits from its unique geographical and climatic conditions, including a long frost-free period and significant temperature variations, which enhance its nutritional content [4]. - The ginseng's saponin content is reported at 8.8%, surpassing imported varieties, while its selenium content is eight times higher than that of imported ginseng [4]. Group 3: Agricultural Practices - To maintain soil fertility, a scientific crop rotation system is implemented, requiring a rest period of 3 to 5 years after ginseng cultivation, which improves quality despite reducing land utilization [5]. - The current cultivation area exceeds 50,000 acres, producing 8,000 tons of fresh ginseng and 2,200 tons of dried ginseng annually, establishing Wending as a key global production area [5]. Group 4: Technological Advancements - The integration of IoT technology in ginseng farming allows for real-time monitoring of environmental conditions, enhancing pest control and decision-making processes for farmers [7]. - Advanced processing techniques, including freeze-drying, have significantly improved the quality and marketability of Wending ginseng products [8]. Group 5: Market Position and Branding - The establishment of the "Wending American Ginseng" brand has strengthened its market position, allowing for higher prices compared to ordinary ginseng, with a premium of 2-3 yuan per pound [9]. - The brand has gained international recognition, successfully entering markets in South Korea, Japan, and Southeast Asia, and has been included in influential agricultural product directories [9].
