| 中文摘要 | 施用蚓糞堆肥已被證實可以減少昆蟲對作物之危害，本研究以蚯蚓餵食不同食物所產生之蚓糞堆肥進行盆栽試驗，以評估其對土壤肥力、小白菜產生之次級代謝物與抗氧化能力及斜紋夜蛾生長之影響。研究結果顯示，不同食物來源會影響蚓糞堆肥之性質，土壤施用蚓糞堆肥可以增加其肥力，土壤有效性硫濃度及小白菜中之硫濃度亦會增加，進而使斜紋夜蛾幼蟲之相對生長速率降低。然而，添加蚓糞堆肥處理對總酚類、總類黃酮及DPPH清除自由基能力並無顯著之影響。 |
| 英文摘要 | Amendments with vermicomposts can reduce the incidence of pests. In this study, earthworms were fed different foods to produce four vermicomposts. A pot experiment was then conducted to assess different vermicomposts’effects on soil fertility, and the secondary metabolite content and antioxidant capacity of Brassica chinensis L., and on the growth of Spodoptera litura larvae. The results showed that the characteristics of vermicomposts are mainly affected by food supplements, and that the application of vermicomposts can improve soil fertility, whereas increasing the soil and leaf sulfur content can decrease the relative growth rate of S. litura larvae. However, there were no significant differences in the total phenolic content (TPC), total flavonoid content (TFC), nor the DPPH free radical scavenging ability under the different treatments. |
| 發表成果與本中心研究主題相關性 | 永續農業需要使用對環境友善之資材，而蚓糞堆肥即為適用之選項之一。本研究證實土壤施用蚓糞堆肥不但可以增加肥力及作物之生長，對於增加土壤碳匯及作物抗蟲亦有顯著之效果，研究結果可作為未來田間應用之參考。 |
