中文摘要 | 本研究為探討觀賞鳳梨催花後,施用液肥及尿素對開花品質之影響。試驗結果Denise品種以催花後第3週才施液肥,盆花品質最好,植株高度最高、花穗長度最長,冠徑最大且花色最豔紅;但Cherry品種卻以催花後第2週施液肥,盆花品質最好,植株高度最高及花穗長度最長,冠徑最大且花色最豔紅。而液肥中最適的尿素濃度,對Denise及Cherry二品種皆以250ppm處理,植株高度最高且冠徑最大。在花色表現上Denise品種以尿素250ppm處理最豔紅,但Cherry品種則以尿素125ppm處理較豔紅。 |
英文摘要 | Fertilization at the third week after flower forcing was the optimum time to obtain better plant height, spike length, flower diameter and flower color on G.” Denise”. Fertilization at the second week after flower forcing could obtain better plant height, spike length, flower diameter and flower color on G.” Cherry”. To both varieties of Denise and Cherry, using 250ppm-urea concentration could obtain higher plant height and bigger flower diameter after flower forcing. Flower color development was best at 250ppm-urea for G. “Denise” and 125ppm-urea for G. “Cherry”. |
