  王美琴、張元聰、楊藹華。2015。控釋型肥料應用於火鶴花栽培之探討。臺南區農業改良場研究彙報66:52-60。

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。

現有技術:農民栽培火鶴花慣行肥料主要為進口好康多或奧妙肥等緩釋型肥料,且以好康多1號(N-P2O5-K2O=14-12-14)或奧妙肥(14-14-14)為主要施用肥料種類。

創新內容:為臺南場研發之生物可分解包膜控釋型肥料,應用於火鶴花栽培。

對產業影響:增加農民栽培花卉作物時不同肥料的施用選擇,進而取代進口肥料使用量,降低肥料使用成本及整體栽培成本。

關鍵字:火鶴花、控釋型肥料、切花產量

Effects of Controlled-release Fertilizer on Leaf Area, Stalk Length and Vase Life on Cut-flower of on Anthurium andreanum Cultivation

Wang M. C., Y. T. Chang and A. H. Yang

Abstract

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.

What is already known on this subject?
The popular fertilizers of Anthurium andreasnum cultivations in Taiwan are commercial controlled-release fertilizers called Hi-control and Osmocote. By far, Hi-control No. 1 (N-P2O5-K2O=14-12-14) and Osmocote (14-14-14) are much more applied among Anthurium growers.

What are the new findings?
The new controlled-release fertilizer (CRF) could apply in greenhouse-grown Anthurium cultivars.

What is the expected impact on this field?
The new CRF may be applied in Taiwan floriculture, and could substitute the use of commercial fertilizers.

Key words: Anthurium andreasnum, controlled-release fertilizer, yield
