Outline of Research at the Start

労働集約型農業では、多めに播種し間引きを行う。この間引きは篤農家の経験・伝承・勘に基づいており、科学的根拠に乏しい。一方、植物は幼少期、単独で生長するよりも幾つかの個体での方が生長に有利であり、生育後期に過密による生長低下とは相反する。つまり、成育初期の小群落、間引きの科学的根拠に基づく栽培法の構築は、農業技術へのゲームチェンジングな試みである。本研究では、「疎と密」効果の実態を分子レベルで解明するために、植物の生長に影響を与える、根から分泌される物質、根系微生物との相互作用、土壌中の微量金属イオン動態の調査を行う。さらに、農書からも関連事項を調査し、領域融合的に、実態解明を目指す。

Outline of Final Research Achievements

The number of seeds sown per unit area was varied in eight steps from sparse to dense. The growth was not better under the sparsest dry matter weight per seedling, but was better when the density was about two levels higher than other conditions. This effect was named the "friend effect." As causes and consequences of this "friend effect," we investigated metal ions in the soil, rhizosphere microorganisms, and genes expressed in plants. There were no characteristic changes in expressed genes and metal ions linked to the cultivation density. On the other hand, there were changes in rhizosphere microflora, and we determined that it was important to examine rhizosphere microflora changes in more detail. Similar studies were also investigated from historical documents and other sources. However, no pertinent results were obtained.

Academic Significance and Societal Importance of the Research Achievements

日本の様に有効な農地が少なく、労働集約型農業の場合、往々にして必要播種数より多めに播種し、栽培途中で間引きを行う。間引きのタイミング・強度等は、篤農家の経験・伝承・勘に基づいており、科学的根拠に乏しい。一方、植物は幼少期、単独で生長するよりも幾つかの個体で小群落を形成した方が生長に有利であり、生育後期に過密による生長低下とは相反する。一方、先述のように従来の農作技術では対応が難しいような地球環境の変化、農業経営・栽培のグローバル化が迫っている。つまり、成育初期の小群落、間引きの科学的根拠の理解に基づく栽培法の改変ができれば、農業技術をゲームチェンジングでき、社会的な意義は大きい。
