摘要

聖誕紅（Euphorbia pulcherrima Willd.）大禧及安琪兩品種以泥炭土、炭化稻殼、土和砂配合添加苦土石灰或矽酸爐渣組成六種不同介質配方供試，調查其生育性狀、介質理化性及植體營養狀況等影響。結果顯示，栽培介質中含土40%者、在株高、展幅、分枝數、葉片數及苞片面積均較無土介質者表現差，故可能還需降低含土量。而無土介質加砂者可增加盆土重量使之穩固不倒伏，而添加苦土石灰或矽酸瀘渣效果類似，對品質有利。

The experiment was conducted to study the effects of six culture media on the growth of poinsetlia. Peat moss, carbonated rice hull, soil and sand in three different ratioes with ground dolomite or silicate slag were used for formulating media. The physical and chemical properties were analyzed and the effects on plant growth and pot quality were also studied. The performance of poinsettia grown in the media mixed with 40% soil was worse than that in the soilless culture. Plant growth and pot quality were significantly improved with the medium added with ground dolomite due to the balance of pH value.
