文登西洋参种植气象因子适宜性分析报告

Meteorological Factor Suitability Analysis Report of American Ginseng in Wendeng

摘要: 文登区作为全国最大的西洋参主产区，其独特的气候条件和土壤特性为西洋参的高品质生产提供了优越的自然环境。本研究基于多源气象数据，结合西洋参生长的关键气象因子，系统分析了文登区西洋参种植的气象适宜性。结果表明，文登区年平均气温12.3℃，极端最高气温36.4℃，极端最低气温−18.2℃；年降水量770.9毫米，主要集中在5~9月；年日照时数2335.9小时，土壤疏松，适宜西洋参生长。此外，文登区西洋参总皂苷含量显著高于国家标准，这与当地冷凉的气候和适宜的降水分布密切相关。本研究为文登区西洋参种植的科学管理及气象灾害防御提供了理论依据，也为其他地区引种西洋参提供了参考。

Abstract: As the largest main production area of American ginseng in China, Wendeng District boasts unique climatic conditions and soil characteristics that provide an excellent natural environment for the high-quality production of American ginseng. Based on multi-source meteorological data and combined with key meteorological factors affecting the growth of American ginseng, this study systematically analyzes the meteorological suitability of American ginseng cultivation in Wendeng District. The results indicate that the annual average temperature in Wendeng District is 12.3˚C, with an extreme maximum temperature of 36.4˚C and an extreme minimum temperature of −18.2˚C; the annual precipitation is 770.9 millimeters, mainly concentrated in May to September; the annual sunshine duration is 2335.9 hours, and the soil is loose, suitable for the growth of American ginseng. Furthermore, the total saponin content of American ginseng in Wendeng District is significantly higher than the national standard, which is closely related to the local cool climate and suitable precipitation distribution. This study provides a theoretical basis for the scientific management and meteorological disaster prevention of American ginseng cultivation in Wendeng District, and also serves as a reference for the introduction of American ginseng in other regions.
