為測試溶磷菌肥 (功) 效在田間的應用，本場選擇臺東地區代表性作物小米，進行溶磷菌在不同磷含量的土壤對小米生長的效應，結果顯示以處理一 (溶磷菌有機肥) 的產量在低及中磷試區與對照有顯著差異，如單純施用液態溶磷菌則在各區均無顯著差異，綜合施肥法以液態溶磷菌為基礎，深入根系施用，與對照有差異，惟可能缺乏能長久維持溶磷菌生存的有機質及養分，因此效益不顯著；綜上試驗顯示參與本試驗之市售二款溶磷菌在小米生長的效應方面高磷區因不缺肥，溶磷菌較無法發揮效益，在中低磷區，因各項養分均不高，因此溶磷菌有機肥得以發揮效用。
In order to test the application of phosphate solubilizing fertilizer in the field, we selected the representative crop millet in Taitung area to carry out the effect of phosphate solubilizing bacteria on the growth of millet with different phosphorus content. The results showed that the yield of treatment one (phosphate solubilizing bacteria within organic manure) was significantly different between the low and medium soil phosphorus content areas with the control. The application of liquid phosphate solubilizing fertilizer was not significantly different in all areas. The comprehensive fertilization method was based on liquid phosphate solubilizing fertilizer, even if it was applied deep into the root system. There may be a lack of organic matter and nutrients that can sustain the survival of phosphate solubilizing bacteria for a long time, so there is no significant benefit in every treatment. The result showed that the two commercially phosphate solubilizing bacteria in this test have no any millet growth promotion in the high soil phosphorus content area, and in the lowand medium- soil phosphorus content area, the nutrients of soil are not high, so the phosphate solubilizing bacteria with organic manure can be effective.
