摘要

在臺灣農民栽培火鶴花慣行肥料多為好康多1號，本試驗臺南區農業改良場研發之生物可分解包膜控釋型肥料，應用於溫室切花型火鶴花栽培，增加農民栽培時不同肥料的施用選擇，以降低進口肥料使用成本。同時比較施用好康多1號或奧妙肥時，EC值變化、植株生長情形及切花產量等。結果顯示在不同肥料施用處理上，各品種切花產量、切花品質及瓶插壽命，均無明顯差異，植株也無肥傷情形產生，但各品種葉片快速生長期之生長量，除天使品種於試驗期間無差異外，丘比特、天使及胖妞品種均以施用本場自行研發之控釋肥，在試驗後期生長量較差。臺南場自行研發控釋肥處理組在試驗期間EC值有升高現象，若能有效改善肥份釋放速率或調整肥料用量，則控釋型肥料可應用於火鶴花切花品種栽培。

In Taiwan, the most popular fertilizer of Anthurium andreasnum cultivations is a controlled-release fertilizer called Hi-control No.1. In this study, we evaluated a controlled-release fertilizer (CRF) which had been developed by Tainan District Agricultural Research and Extension Station. The new CRF was applied in greenhouse-grown anthurium to compare with Hi-control No.1 and Osmocote. The EC value, plant growth rate and yields of cut flowers were surveyed. The result indicated the releases of fertilizers were affected by different seasons, plant growth rates and the degradation of medium. During the rapid growth stage of leaves, growth rates of commercial fertilizers were better than the new CRF. The production of cut flowers and vase lives did not differ among all treatments. The earlier release rate of new CRF is still the main issue. As the higher EC value of CRF made by TDARES is improved, the new CRF may be applied in floriculture.
