金針菇堆肥在本瓜及梨育苗之研究

Winter Mushroom Compost as a Medium for the Seed Germination and Growth of Papaya and Pear

木瓜台農二號種子在金針菇堆肥的發芽率與對照組（peatmoss :perlite=1:1）相同高達87.5%，其發芽勢較對照組集中，但木瓜幼苗期生長較對照組差，且葉片有缺氮黃化現象，添加養液後，對木瓜苗生長都有改善效果，而金針菇堆肥混合泥炭苔的植株其株高、鮮重、乾重皆與對照組相近。以金針菇堆肥／泥炭苔／砂（6:6:1, v/v）栽培臺灣原產梨（Pyrus kawakami），其株高、莖粗與對照組相近或更好。綜合以上試驗結果顯示，金針菇堆肥可混合較粗的粒子改善其物理性；混合有機質如泥炭苔、粕類等改良其化學性，作為育苗栽培介質應是深具潛力的。

The germination rate of papaya seeds in winter mushroom Flammulina velutipes) compost is the same as control (peatmoss: perlite = 1:1,v/v), but the growth of seedlings was inferior to control and showed nitrogen deficiency slightly. The mixture of winter mushroom compost with other organic (peatmoss, seed pomaces etc.) and inorganic components (vermiculite, sand etc.) have been desired to improve those weakness. The shoot length and stem diameter of Pyrus kawakami were similar or greater than control in SWMC/peat/sand (6:6:1,v/v). All the results show that modified winter mushroom compost has the potential to grow horticultural crops for liner production.
