| 摘要 | [Objectives] Farmland ginseng cultivation, as a sustainable alternative to traditional forest-clearing ginseng planting, requires systematic evaluation of soil optimization strategies. This study aimed to quantify the linkage between soil improvement outcomes and ginseng (Panax ginseng) yield across five regions in Yanbian Korean Autonomous Prefecture. [Methods] Soil improvement trials were conducted using farmland soils, with forest soils as the baseline. Soil nutrient contents were measured via soil agrochemical analysis method using a continuous flow analyzer. Statistical approaches, including significance tests, correlation analysis, and regression analysis, were applied to identify key factors influencing yield. [Results] Ginseng yield exhibited a significant positive correlation with organic matter content and available phosphorus, but a negative correlation with electrical conductivity, ammonium nitrogen, and available potassium. Wangqing and Liucai regions achieved post-improvement yields equivalent to 94% and 88% of forest soil yields, respectively, demonstrating the highest soil similarity to forest ecosystems. [Conclusions] Region-specific soil improvement protocols in Wangqing and Liucai show high replicability and efficacy. These strategies can serve as benchmarks for sustainable farmland ginseng cultivation, minimizing ecological disruption while maintaining productivity. |
