本研究的目的是通过比较冈山县和香川县，阐明濑户内地区双季水稻种植存在的因素。由于对新需求大米的政策支持以及2010年代后气候变化造成的高温灾害，水稻品种的多样化正在取得进展。我们阐明了推广晚熟品种是维持一年两熟农业的必要条件。冈山的大农户可以延长种植期，而香川的社区农场由于灌溉规则和没有晚熟品种的小麦收获较晚，无法扩大农场规模。
The objective of this study is to clarify factors for the existence of double cropping paddy farming in the Setouchi region, comparing Okayama and Kagawa Prefecture. Diversification of rice varieties has been progressing due to the policy supports for new demand rice and the high temperature damages caused by climate change after the 2010s. We clarified that disseminating late-ripening varieties is necessary to maintain double cropping farming. Large farmers in Okayama could extend the planting period, while community farms in Kagawa could not expand their farm size due to irrigation rules and late harvest of wheat without late-ripening varieties.
