| 中文摘要 | 在追求環境永續和糧食安全的過程中，生物炭已成為緩解連作障礙（CCOs）的有前景的土壤改良劑。本研究探索了具有高吸附能力的工程化生物炭（WP400）在芹菜栽培中的應用，旨在緩解連作障礙。研究利用液相色譜四極飛行時間質譜（LC-QTOF/MS）進行目標及嫌疑分析，並採用 Biolog EcoPlate™ 追踪土壤細菌的功能多樣性，檢測在不同 P400 施用量下的化學和微生物相互作用。結果顯示，WP400 增強了芹菜的生長，降低了病害的嚴重程度，並吸附了潛在的自毒物香豆酸（COU）。此外，還鑑定出其他潛在的化感物質，主要是與脂肪酸相關，暗示脂肪酸在化感作用中可能具有更廣泛的角色。WP400 還影響了土壤細菌的碳利用，並改變了微生物群落結構。然而，高劑量 WP400（0.8% w/w）可能不利於芹菜生長，並降低了細菌的代謝潛力，顯示其效果存在限制。適當施用 WP400 可為緩解連作問題提供可持續的解決方案，促進環境永續與農業發展。 |
| 英文摘要 | In the pursuit of environmental sustainability and food security, biochar has emerged as a promising soil conditioner to mitigate continuous cropping obstacles (CCOs). This study explored the use of engineered biochar (WP400) with high adsorption capacity for phenolic acids in celery cultivation. Using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF/MS) for both target and suspect analyses, along with Biolog EcoPlate™ to track the functional diversity of soil bacteria, the study examined chemical and microbiological interactions at varying P400 application rates. WP400 enhanced celery growth, reduced disease severity, and adsorbed p-coumaric acid (COU), a potential autotoxin. Additionally, other potential allelochemicals, predominantly fatty acid-related, were identified, suggesting a broader role for fatty acids in allelopathy. WP400 also influenced soil bacterial carbon utilization and altered microbial communities. However, higher WP400 doses (0.8% w/w) may not be beneficial for celery growth and reduced bacterial metabolic potential, indicating limitations to its effectiveness. Proper application of WP400 provides a sustainable solution for alleviating continuous cropping issues, promoting both environmental sustainability and agricultural development |
| 發表成果與本中心研究主題相關性 | 利用物理化學方法製備的生物炭，可用來處理農業生產時的連作障礙問題，本研究以芹菜為標的作物，將生物炭施入有連作障礙的土壤中，觀察其對減緩芹菜連作障礙的原因，結果發現，化學自毒物質並非導致連作障礙的直接原因，而是化學物質誘導致病微生物的生長及對部分含氮養分吸收的差異所致，本研究除可循環利用廢棄農業資材外，亦可將此資材重複回歸於土壤中解決農業的問題，符合中心的宗旨。 |
