Abstract
為探討與建立本省荔枝園營養診斷方法，以供肥培改進之依據與參考，本研究應用葉片與土壤分析，針對台中縣、南投縣市及彰化縣約30個荔枝園，於1997年起進行營養與肥培管理調查。品種主為黑葉，次為糯米滋。產量調查及葉片分析結果顯示，產量與葉片氮含量呈二次式相關且葉片氮含量大多高於二次式中產量最高點的葉片氮含量，尤其花期（包括始花，2-4月）葉氮高於1.90%以上時收量減低，由迴歸程式求得最高產量90%之花期葉片氮素含量範圍為1.50-1.90%。至於葉片磷、鎂、鈣及硼含量與收量之迴歸分析則呈正相關，其相關r值 (n = 52) 分別為0.498**、0.561**、0.444**、0.543**，達極顯著（l%）水準。收量60公斤／株以上之植株，其花期（包括始花，2-4月）至謝花著果（5月）之葉片養分狀況，通常磷、鎂、鈣及硼分別為0.09%，0.30%，0.90%及25mgkg -1以上。
The aims of this study were to establish the mehtod and the reference of nutrient diagnosis as guides for fertilization improvement in lychee orchards. Thirty farms located in central Taiwan were selected to survey the changes of nutrient contents of leaves and yields of cvs Haak Yip and No May Tsz, and of soil fertility during the growing season in 1997. Some nutrients’ contents of leaves were significantly related to each other. Data revealed that the fruit yield of cv. Haak Yip was described well by nitrogen content in a quadratic relation and with the highest yield at 1.71% of nitrogen. Results also showed that the nitrogen content for most farms were higher than this value.
