摘要

本研究之微生物液肥分為氮質液肥及磷鉀質液肥，氮質液肥之氮、磷、鉀含量分別為0.58、0.14、0.58%，而磷鉀質液肥之氮、磷、鉀含量分別為0.3、0.23、1.36%。植栽試驗之植株葉片分析結果顯示，氮質液肥處理之葉片氮含量為所有處理中最高，而葉片磷含量則以磷鉀質液肥處理最高，而植株鮮重調查，葉萵苣綠珊瑚品種在液肥澆灌第4 週後，以氮質液肥處理產量最高(88.5 克)，但市售液肥處理是所有處理中最低的(35.6 克)；葉萵苣翠妹品種在液肥澆灌第4 週後，以磷鉀質液肥處理植株鮮重最高(110.9 克)，而市售液肥處理仍是所有處理中最低的(23.0 克)。綜合以上結果顯示微生物液肥確有其效果，但同一作物不同品種，其植株生長呈現不同結果，未來值得持續進行其他作物之效果試驗。

In the study, nitrogen, phosphorus, potassium content of nitrogen microbe liquid fertilizer and phosphorus and potassium microbe liquid fertilizer were 0.58、0.14、0.58% and 0.3、0.23、1.36%, respectively. The plant nutrient element analysis datas showed the leaf nitrogen content of plant grown with nitrogen microbe liquid fertilizer was the highest, and leaf phosphorus content of plant grown with phosphorus and potassium microbe liquid fertilizer was the highest among the treatments. The fresh weight of lettuce (Lactuca sativa, green coral) plant grown with nitrogen microbe liquid fertilizer was the highest and grown with the commercial liquid fertilizer was the lowest at 4 weeks after planting. The fresh weight (Lactuca sativa, chui-mei) plant grown with phosphorus and potassium microbe liquid fertilizer was the highest and the plant grown with commercial liquid fertilizer was the lowest. The plant culture experiment result showed microbe liquid fertilizer was helpful to the growth of plant growth, but it's effect was different between different varieties. At last, it is need to study the effect on other plant in the future.
