中文摘要 | 本研究之目的在評估依據盆栽聖誕紅生育期間植體營養吸收量,調配養液配方,並探討專用養液配方及施肥頻率對盆栽聖誕紅生長及品質之影響,建立一套完整的盆栽聖誕紅營養管理模式,作為養液配方及施肥推荐之依據,以增進聖誕紅品質及商品價值。盆栽聖誕紅最適施肥濃度可界定在插植成活後至花芽形成前N-P-K-Ca-Mg=160-32-210-55-32 mg/l,花芽形成至出售N-P-K-Ca-Mg=400-32-530-55-32mg/l。最適施肥頻率為每二天施用一次,五寸盆每次灌施量為100ml。 |
英文摘要 | This study is aimed to determine the effect of different concentrations and application frequencies of N, P, K, Ca and Mg on the plant growth and quality of potted poinsettia. Results showed that optimum N-P-K-Ca-Mg application concentration of fertilizers were 160-32-210-55-32 mg/l used at growth stage after establishment and prior to flower formation and 400-32-530-55-32 mg/l used at flower formation to harvest. The optimum application frequency of fertilizers was once every two days and the amount of nutrient solution was given with 100 ml/pot at each application. |
