| 英文摘要 | The impacts of long-term (1996–2019) fertilizer inputs on grain yield and edaphic factors of upland maize and wetland rice rotation system were assessed for sustainable intensification of agriculture. Subtropical field treatments included swine manure compost (CP), chemical fertilizer (CF, control), no fertilizer (CK, blank), inorganic N-amended CP (CPN1 and CPN2), peat (PN1) and green manure (GMN1). Maize exhibited a significantly increased yield trend under CF, GMN1 and CP-based inputs (CP, CPN1 and CPN2), whereas rice yield displayed a non-significant marginal improvement or negative result. Principal component analysis of edaphic factors revealed distinct clustering of CP-CPN1-CPN2, CF-GMN1-CK and PN1 samples during maize-rice rotation. CP-based inputs in particular improved OM, EC, microbial metabolism and nutrient availability during crop rotation. Pronounced soil microbial activity and Bacterial abundances were recorded during maize cultivation. In contrast, low aerobic metabolism coupled with high Bacterial and Archaeal species richness, diversity and evenness were found during rice cultivation. In conclusion, increasing maize yield trends observed under long-term CP-based inputs were on par with CF and GMN1 amendments that concurrently acidified soil. Numerically dominant aerobic Bacteria appear to drive nutrient recycling and promote maize grain yield, whereas metabolically lethargic diverse prokaryotes constrained nutrient turnover stagnating the rice yield. |
| 發表成果與本中心研究主題相關性 | 長期水旱輪作系統下 (1996-2019年) 應用不同的施肥處理可逐年增加旱作玉米產量，而水稻產量則顯示遲滯現象，尤其可見於 CF、GMN1 和CP 的施肥調整結果。長期應用 CPN1 與 CF 相比，在統計上顯著提高了玉米和水稻的平均產量。調整堆肥的處理可維持土壤的 pH、EC、SOM，顯著提高植物所需元素的可利用性、促進原核生物（包括細菌和古細菌）的多樣性，並抑制玉米和水稻田土壤中的氨氧化菌 (Thaumarchaeota) 和厭氧甲烷菌 (Euryarchaeota)。相較之下，化肥與綠肥處理導致土壤 pH、EC、SOM、大量/微量元素和生物多樣性下降。在玉米-水稻輪作系統以堆肥添加部份化肥的施肥策略是一種永續的農耕方式，可提昇了土壤營養元素、作物產量和土壤微生物的多樣性。提供台灣亞熱帶長期水旱輪作及不同施肥試驗田區永續經營之參考。 |
