However, heavy application of fertilizer is considered to cause drought stress because the water-holding capacity of the nursery box decreases. The objective of this study was to elucidate the possibility of drought injury of rice seedlings in a nursery box with heavy, one-shot application of controlled-release fertilizer. We examine the drought stress for three fertilizer application levels (0, 600, 1200 g/box), nine types of potting soils, two periods (a covered period for retaining heat by plastic film in the initial stage of seedlings and the subsequent uncovered period with daily watering), and three methods of seeding (seeding on a mixture of soil and fertilizer and covering with soil ; adding potting soil first, applying fertilizer on the potting soil, seeding on the fertilizer, then covering with soil ; and putting down fertilizer first, applying potting soil on top, seeding on the potting soil, then covering with soil). In the covered period, the water content of the surface soil had a high correlation with ratio of standing. Using high-water-holding-capacity potting soil and seeding on soil but not on fertilizer increased the water content of covered soil and the standing ratio. In the uncovered period, the water content of nursery boxes had a significant correlation with the dry matter of seedlings, but the coefficient of determination was small (r^2=0.13). We concluded that the most critical period for the risk of drought stress is the covered period, and that the selection of potting soil with a high water-holding capacity and the application of seeds on soil rather than fertilizer are important techniques to avoid drought injury.\n","subitem_description_type":"Abstract"},{"subitem_description":"水稲の疎植栽培の普及などにより、育苗箱全量施肥を行う際、苗箱への肥料の多量施用が必要となる機会が増えている。肥料の多量施用は苗箱中の保水性や苗の生育に影響を及ぼす可能性がある。そこで本研究では多量施用を行った場合の育苗時の乾燥ストレスの可能性について検討を行った。施用量は0, 600, 1200g/箱とし、培土の種類、施肥位置 (混合、層状施肥、箱底施肥) をかえ、無加温育苗での農業フィルムの被覆期間と灌水開始以降の水分環境について検討した。被覆期間においては表面から5mmの土壌の水分と出芽率の間に有意な正の関係がみられ、最大容水量が大きい培土、または箱底施用で表層土壌の含水比が高まり、出芽率が高くなった。被覆除去後においては苗箱の保水性と苗の乾物重に有意な関係は見られたが、決定係数は小さかった (r^2=0.13)。以上から被覆期間において出芽率が低下するリスクを第一に考える必要があり、これを防ぐためには最大容水量の大きな培土を選ぶこと、箱底に施肥することが効果的だと結論した。\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001293","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人
