摘要

黃椰子在50%雙層遮光網下栽培，切葉品質最佳。切葉產量卻以單層50%遮光網下，每叢每年17片較多。至於瓶插壽命則以50%雙層及單層遮光網下15及14天最長。在雙層遮光網下栽培，施肥量每年每公頃1440公斤處理黃椰子葉長、葉寬及產量明顯優於480公斤及不施肥處理施肥量每公頃960公斤處理黃椰子葉長、葉寬明顯優於480公斤及不施肥處理。在單層遮光網下，施肥處理黃椰子切葉品質明顯優於不施肥處理，在施肥量處理間，施肥量1440公斤黃椰子葉長、葉寬、瓶插壽命及產量均顯著優於480公斤。產量及瓶插壽命隨施用0、480、960及1440公斤肥料，而呈遞增的趨勢，產量分別爲19、23、25及27片，瓶插壽命分別爲12、14、15、16天。露天下栽培，黃椰子切葉品質雖然不佳，但施肥比不施肥處理可提昇切葉品質。瓶插壽命及產量亦隨著施肥量增加，而呈增加的趨勢。

The foliage quality of yellow butterfly pains was the best if it was cultivated under 50% double shading environment. The yield of foliage was 17 slices all year when it was cultivated in 50% shading. The vase life of foliage was 15 and 14 days respectively under 50% double and single shading. Fertilized 1440 kg compound fertilizer (N:P2O5:K2O=20:5:10) per year, the leaf length, leaf width mod yield of the plants were significantly better than plants fertilized 480 and 0 kg per year under 50% double shading environment. Treatment of fertilizing 960 kg compound fertilizer per year, plant leaf length, leaf width were significantly better than plants fertilized 480 and 0 kg per year. Foliage quality of plant fertilizing was better than plant not applied fertilizer under 50% shading environment. Fertilized 144 0kg per year, the leaf length, leaf width, vase life and yield of plants were significantly better than plants fertilized 480 kg per year. Foliage yield were 19、23、25、27slices and sane life were 12、14、15、16days respectively by applying fertilizer 0、480、960 and 1440 kg per year. In outdoors, though the foliage quality was the worst, fertilizing treatment could promote its quality. According to the increase of using fertilizer, the foliage yield and vase life would increase us well.
