Changes in dietary patterns have led to a decrease in rice consumption, raising demands for the cultivation of alternative crops that meet the current requirements. Potatoes are highly productive and can be stored for a relatively long period, thereby ensuring adequate income for farmers; however, optimal cultivation is necessary to maximize yield.
This study proposes optimal cultivation regions for potato considering climate and soil conditions.
The CLIMEX model was developed to evaluate climatic suitability, while the soil suitability was scored based on five soil characteristics. The final areal suitability for potato cultivation was classified into 4 levels: very suitable, suitable, marginal, and unsuitable.
Overall, 36.5% of South Korea had very suitable climate, but areas with the best values for soil conditions were approximately 10% of the climatically suitable areas. When considering the climate and soil conditions simultaneously, climatic suitability and soil condition were inversely related, resulting in only 1.2% of optimal areas with Jeju Island as the most suitable area.
Because both climate and soil conditions need to be suitable for growing crops, this study can provide potential paddy-cultivation areas for potato cultivation and a method for evaluating suitable areas for crop cultivation.
饮食模式的变化导致大米消费量下降，从而增加了对符合当前需求的替代作物种植的需求。土豆产量高，且可储存较长时间，从而确保农民有足够的收入；然而，需要进行优化种植以实现产量最大化。
本研究提出考虑气候和土壤条件的土豆最佳种植区域。
开发CLIMEX模型以评估气候适宜性，同时根据五种土壤特性对土壤适宜性进行评分。土豆种植的最终区域适宜性分为4个等级：非常适宜、适宜、边际适宜和不适宜。
总体而言，韩国36.5%的地区气候非常适宜，但土壤条件最佳的区域约为气候适宜区域的10%。同时考虑气候和土壤条件时，气候适宜性与土壤条件呈负相关，导致只有1.2%的最佳区域，其中济州岛是最适宜的区域。
由于气候和土壤条件都需要适宜作物生长，本研究可为土豆种植提供潜在的稻田种植区域，并提供一种评估作物种植适宜区域的方法。
