番石榴是原產熱帶淺根性果樹，選擇於不同時期進行修剪即可調節為周年生產，由於栽培管理簡單，果實產量高，施肥效果顯著影響品質與產量。如何在適時、適量與適法施用有機質與化學肥料，則須依據土壤特性選擇適宜之肥料種類，再依品種特性、樹齡、整枝修剪程度、產期調節模式，與留果量等，來擬定肥培管理方法，提高肥料效率，與維持果園良好之土壤肥力。施用有機質肥料為主的管理，果實品質較佳。番石榴葉片礦物營養診斷時，營養診斷用的葉片為當年結果枝或未結果枝上，葉齡5－6個月之葉片為宜。

As the root system of guava is shallow. yield and fruit quality of guava are strongly influenced by fertilization management. Cultural techniques such as training and pruning to dwarf and forcing culture to supply fulfilled fruit all the year around are popularly utilized in the industry. Meanwhile, cultivated with organic fertilizers was much higher than those cultivated with chemical fertilizers. Leaf analysis showed that leaves with the age of 5-6 months has stable concentration of nitrogen, phosphorus and potassium and are better for nutrition diagnosis of guava tree.
