遮蔭與施肥間隔對臺灣一葉蘭產量與開花之影響

Effect o Shade and Fertilization Intervals on Yield and Flowering of Pleione Formosana

在臺灣中部海拔2100m梅峰農場栽培臺灣一葉蘭，於生長期間（4~10月）予50%遮蔭，球莖產量高，開花品質佳。不遮蔭及遮蔭25%者，葉片日燒嚴重，球莖產量較低，並增加球莖之腐敗率，遮蔭75%者，雖產量與遮蔭50%者相近，但增加消蕾率，降低開花品質。每週施肥一次較每2或4週施肥一次者佳，而光線強度與施肥次數間似無多大關係。

Pleione formosana grown in highland of Mei-Feng (2100m above sea level) had to be shaded 50% under f all light conditions during growing season from April through October to get high yield and flowering quality. Sun scorch on leaven and corms under fall light conditions or 25% shade level triggered leaf senescence that decreased corm yield and increased percentage of corm decay. Plants given 75% shade level increased flower-bud bloating although the corm yield was similar to 50% shade level. Plants receiving fertilization weekly had greater fresh weight than those receiving fertilization two and four-week intervals. There are no. interaction between light intensity and fertilization frequency.
