Abstract
近年來運用農業廢棄物製作生物炭來改善土壤性質已慢慢受到重視。施用碳化稻殼可改善土壤物理性質和促進土壤微生物活性，使作物根部生長良好。本研究以結球萵苣‘常利 6 號’為測試品種，進行施用碳化稻殼增加土壤碳匯試驗。除了球高及生物量處理差異達 5%顯著水準外，包括產量等其他園藝性狀各處理間並無顯著差異，因此結球萵苣栽培至少可以添加 2,500 公斤/0.1 公頃之碳化稻殼至土壤中。田區土壤分析結果為水分含量及總體密度處理間沒有顯著差異，但隨著施用碳化稻殼次數增加，土壤有機碳儲量有略為增加的情形。因此栽培結球萵苣田區施用碳化稻殼，可以提升土壤碳匯能力。
In recent years, the use of agricultural waste to produce biochar for improving soil properties has gradually gained attention. The application of rice husk carbon can improve the physical properties of the soil and promote soil microbial activity, leading to better crop root growth. In this study, we used iceberg lettuce ‘Chang Li No. 6’ as the test crop to conduct experiments on increasing soil carbon sequestration by applying rice husk carbon. Apart from significant differences in plant height and biomass at the 5% level, there were no significant differences among treatments in other horticultural traits, including yield. Therefore, in the cultivation of iceberg lettuce, at least 2,500 kg / 0.1 ha of rice husk carbon can be added to the soil. Soil analysis results showed no significant differences in moisture content and bulk density among treatments, but with the increased application of rice husk carbon, there was a slight increase in soil organic carbon density. Applying rice husk carbon in iceberg lettuce cultivation areas can enhance the soil's carbon sequestration.
