本研究目的在針對市售2 種溶磷菌，對玉米肥效及整合性施肥應用進行評估。肥效試驗方面：玉米含苞葉穗重及單軸穗重，分別以½施肥量＋滅菌液處理及½施肥量＋菌液處理，顯著高於全量肥料推薦用量處理，在可溶性固形物 (°Brix ) 之表現，各處理間無顯著差異。在整合性施肥應用方面：春作於酸性土壤之試驗結果顯示，不施有機肥處理方面，僅單軸穗重½肥料推薦用量＋菌粉處理，顯著優於全量肥料推薦用量處理。在基肥施用稻殼灰炭方面，½肥料推薦用量＋菌粉及菌液2 個處理，在含苞葉穗重及單軸穗重，均顯著優於全量肥料推薦用量處理。在秋裡作於鹼性土壤之試驗結果顯示，含苞葉穗重及單軸穗重，均以⅔肥料+菌液及全量肥料+菌粉2 項處理，顯著優於對照組。而在可溶性固形物之表現，2 期作各處理間，均無顯著優於對照組。
The purpose of this study was to evaluate the effects of corn fertilization and integrated fertilization on two commercially available phosphate solubilizing bacteria.The fertilizer efficiency test showed that: The ear weight and uniaxial ear weight of maize were treated with 1/2 fertilization amount + sterilizing solution and 1/2 fertilization amount + bacterial liquid treatment, which was significantly higher than the recommended dosage of whole fertilizer. There was no significant difference between the treatments at °Brix. The integrated fertilization application showed that: Spring was tested in acidic soil, and no organic fertilizer treatment was applied. Only uniaxial ear weight 1/2 fertilizer recommended dosage + bacterial powder treatment, significantly better than the total amount of fertilizer recommended treatment. In the application of rice husk ash biochar in base fertilizer, the recommended dosage of ½ fertilizer + bacterial powder and bacterial liquid treatment, the weight of glutinous leaves and the weight of uniaxial ears were significantly better than the recommended dosage of whole fertilizer. Test for alkaline soil in autumn: In the weight of glutinous tassel and uniaxial ear weight, it was treated with ⅔ fertilizer + bacterial liquid and full fertilizer + bacterial powder, which was significantly better than the control group. Performance at °Brix showed that: There was no significant difference between the two treatments in the treatments.
