氮磷鉀肥施用量對生薑產量的數據分析
Data Analysis of Nitrogen, Phosphorus, and Potassium Fertilizer Application Rates on Ginger Yield
摘要
為探討氮肥、磷肥與鉀肥施用量對於生薑產量之影響，以提供生薑生產管理作業的施肥依據，此研究收集附有實驗數據的研究文獻進行數據分析。以產量為他變數，氮肥、磷肥與鉀肥施用量為自變數，使用迴歸分析建立其經驗公式。品種，栽培地區等因子作為分類變數，用以評估各影響因子的顯著影響性。共有10篇論文數據用以研究。結果顯示氮肥、磷肥與鉀肥施用量對於產量的影響公式為各自變數的二次方程式。不同肥料的相互作用對於生薑產量無顯著影響。中國三組黃薑試驗數據無顯著差異，然而白薑數據與黃薑數據有顯著差異。不同國家（奈及利亞與墨西哥）的研究數據與中國黃薑數據有顯著差異。以適稱公式進行最佳化分析，氮肥之適用施肥量（533.6～667.4 kg/ha），鉀肥之適當施肥量範圍為607.0～885.1 kg/ha。鉀肥之適用施肥量並無合理結果。台灣農業單位所發行之施肥手冊，對生薑肥料推薦使用的氮肥與鉀肥施用量相對偏低。建議進行嚴謹之施肥試驗，以訂定推薦生薑生產施肥之最佳施用量。

To explore the impact of nitrogen, phosphorus, and potash fertilizer application rates on ginger yield, and to provide a fertilization basis for ginger management operations, this study collected literature in experimental data for data analysis. Taking the yield as dependent variables and the application rates of nitrogen, phosphorus, and potassium fertilizer as independent variables, regression analysis was used to establish its empirical equations. Varieties, cultivation regions, and other factors are used as categorical variables to evaluate the significant influence of each influencing factor. A total of 10 data sets were used for studying. The results indicate that the empirical equations for the effect of nitrogen, phosphate, and potassium fertilizer application rates on yield are the quadratic equations. The interaction of different fertilizers had no significant effect on ginger yield. There was no significant difference in the three groups of yellow ginger test data in China, but there was a significant difference between the white ginger data and the yellow ginger data. Experimental data from different countries (Nigeria and Mexico) are significantly different from Chinese ginger data. Optimization analysis was conducted based on adequate equations. The suitable fertilizer dosage range of nitrogen fertilizer is 533.6~667.4 kg/ha, and the suitable fertilizer dosage range of potassium fertilizer is 607.0~885.1 kg/ha. There is no reasonable result for the appropriate fertilizer application rate of potassium fertilizer. The fertilization manual issued by Taiwan's agricultural institute recommends relatively low nitrogen and potassium fertilizer application rates for ginger fertilizers. It is recommended to conduct rigorous fertilization trials to determine the optimal dosage of recommended fertilization for ginger production in Taiwan.
