Identifying suitable site for growing mountain-cultivated ginseng is a concern for ginseng producers. This study was conducted to evaluate the soil properties of cultivation sites for mountain-cultivated ginseng in Hamyang-gun, which is one of the most well-known areas for mountain-cultivated ginseng in Korea.
The sampling plots from 30 sites were randomly selected on or near the center of the ginseng growing sites in July and August 2009. Soil samples for the soil properties analysis were collected from the top 20 cm at five randomly selected points.
Mountain-cultivated ginseng was grown in soils that varied greatly in soil properties on coniferous, mixed, and deciduous broad-leaved stand sites of elevations between > 200 m and < 1,000 m. The soil bulk density was higher in Pinus densiflora than in Larix leptolepis stand sites and higher in the < 700-m sites than in > 700-m sites. Soil pH was unaffected by the type of stand sites (pH 4.35-4.55), whereas the high-elevation sites of > 700 m were strongly acidified, with pH 4.19. The organic carbon and total nitrogen content were lower in the P. densiflora stand sites than in the deciduous broad-leaved stand sites. Available phosphorus was low in all of the stand sites. The exchangeable cation was generally higher in the mixed and low-elevation sites than in the P. densiflora and high-elevation sites, respectively.
These results indicate that mountain-cultivated ginseng in Korea is able to grow in very acidic, nutrient-depleted forest soils.
为种植人参寻找合适的场地是人参种植者关注的问题。本研究旨在评估韩国闻名的汉拏山人参种植区之一——海南郡的人参种植场地的土壤特性。
2009 年 7 月至 8 月，在人参种植场地的中心或附近随机选择了 30 个采样点。从五个随机选择的点采集了表层 20cm 土壤样本，用于分析土壤特性。
在海拔 200m 以上至 1000m 以下的针叶林、混交林和落叶阔叶林种植场地，人参生长的土壤特性差异很大。在赤松种植场地的土壤容重高于落叶松种植场地，而在 700m 以下的场地高于 700m 以上的场地。土壤 pH 值不受林分类型的影响（pH 值为 4.35-4.55），但 700m 以上的高海拔地区则呈强酸性，pH 值为 4.19。赤松种植场地的有机碳和全氮含量低于落叶阔叶林种植场地。所有林分场地的有效磷含量均较低。可交换阳离子含量在混交林和低海拔地区通常高于赤松和高海拔地区。
这些结果表明，韩国的人参能够在非常酸性、养分贫瘠的森林土壤中生长。
