| 内容記述 | Biodegradable plastics applied to soil stimulate the production of greenhouse gases and inhibit plant growth under aerobic conditions. This study aimed to examine the effects of biodegradable plastics on paddy rice growth and greenhouse gas emission under flooding conditions in pot experiments and also on greenhouse gas production under flooding conditions in an incubation experiment. Two series of pot experiments were conducted with rice (Oryza sativa). First series as immediate flooded and 2nd series as 2 weeks nonflooding before flooded, and both kept flooded until harvest. The following four kinds of materials were added to the sandy paddy soil, 1) nonwoven fabric sheets made of polylactic acid and polybutylene-succinate, 2) laminate sheets made of polybutylene adipate terephthalate and pulp, 3) cellulose filter paper, and 4) rice straw. Only soil was used as control. Methane (CH4) emission, measured by chamber method followed by gas chromatography, was significantly larger only in the cellulose treatment than the laminate treatment in the immediate flooded series, indicating that biodegradable plastics had no significant impact on CH4 emission from paddy rice soil. Rice growth and yield did not show significant difference among treatments in both series. Incubation experiment showed the largest CH4 production in cellulose-amended soil, followed by straw-amended and laminate amended soils, and least in fabric-amended soil, while CO2 did not show significant differences among treatments. We need further examination with different biodegradable plastics for a longer period that test used in this study. | |||||||||||||

| 内容記述 | 生分解性プラスチックが湛水条件下の温室効果ガス放出と水稲生育に及ぼす影響を調べた。 生分解性プラスチックは畑土壌で温室効果ガス放出を加速化しコマツナ生育を阻害することが先行研究で認められていたが、本研究では畑に隣接する水田から採取した土壌に同種の生分解性プラスチックを添加し、ポット試験で水稲を栽培して、温室効果ガス、メタンの放出と水稲生育に及ぼす影響を調べた結果、 ・2種類の生分解性プラスチックの添加は無添加と比較してメタン放出に影響はなかった。 ・水稲生育や収量にも影響を及ぼさないことが示された。 ・プラスチック添加後、直ちに湛水しても2週間畑状態後に湛水しても結果は変わらなかった。 |
