中文摘要 | 本研究之目的,在評估栽培介質之物理性質對聖誕紅生長及品質的影響,以界定聖誕紅栽培介質物理性質適宜值範圍,提供花農調配栽培介質之依據。栽培介質材料為堆肥(牛糞:粉碎穀殼:金針菇木屑=1:2:2(v/v/v)混合堆積腐熟)、河砂及矽石。試驗結果顯示,栽培介質總體密度、質材密度、總孔隙度、容水量及保水力等物理性質對盆栽聖誕紅性狀均有不同程度的影響,依據其影響程度界定盆栽聖誕紅栽培介質總體密度、質材密度、總孔隙度、容水量及保水力之最適範圍,分別為0.62g/cm3以下、1.15g/cm3以下、46.5%以上、55%以上及30%以上。 |
英文摘要 | This study was established to determine the criteria of physical properties of growth media to provide a proper formulation for potted poinsettia production. The media were made by mixing compost (cow dung, crushed rice hull and mushroom residue mixture with the ratio of 1:2:2 v/v/v), sand and expanded clay. Assessments of optimum the physical properties of growth media for potted poinsettia showed that the plant characters were affected to a certain extent by bulk density, particle density, total porosity, water capacity and water-holding capacity of growth media. Based on crop response, the optimum conditions for the growth media were proposed for bulk density below 0.62 g/cm3, particle density below 1.15 g/cm3, total porosity above 46.5%, water capacity above 55% and water-holding capacity above 30%. |
