Outline of Research at the Start

作物の生長およびバイオマス・収量の精緻な予測は,最適な営農ポリシーの導出,単収の増加,農作業の省力化を実現する上で必要不可欠である.しかし,農業に関与する実世界の現象は複合的かつ連鎖的で非常に複雑である.また,センシング技術の進展により取り扱えるデータ量は増えたが,特性が多様でありデータ分析の難しさが増している.本研究課題では,データ同化技術により作物モデルと数理統計手法を融合させ,直接観測できない情報を推定し,農業従事者の意思決定に資する予測情報の提供が可能な空間スケールに非依存な高精度シミュレーション技術の確立を目的とする.

Outline of Final Research Achievements

The aim of this study was to establish a highly accurate simulation technique that is independent of spatial scale and can reasonably estimate parameters such as data and conditions that are difficult to observe directly by integrating an integrated crop growth model with mathematical and statistical methods, based on consistency with the model. The effectiveness of data assimilation and measurement of LAI and grass height of tomato was verified, and the prediction accuracy of LAI was improved. On the other hand, prediction accuracy did not improve for yield, which was expected because of improved LAI reproduction and prediction accuracy. Future work includes the addition of model parameters to the expanded spatial vectors and the application of new methods to optimize the estimation of model parameters. These results have been published in 13 refereed papers and 10 conference presentations during the research period.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は,統合型作物モデルと数理統計手法の融合により,観測困難なデータや条件を合理的に推定し,空間スケールに依存しない高精度なシミュレーション技術を確立することである.この技術により,作物の生長や収量の予測精度が向上し,農業の効率化と省力化に貢献できる.また,UAVや人工衛星を活用することで,広範囲の圃場情報を効率的に収集し、農家の意思決定を支援するシステムを構築することが可能である.
