本研究目的在於探討利用牛糞、稻殼、蔗渣及金針菇類太空包廢渣等本土化有機廢棄物對木瓜幼苗生長之影響，以期評估作為木瓜育苗介質材料之適用性。由試驗結果顯示，使用未經堆積腐熟之牛糞為育苗介質材料，對木瓜種子發芽率及木瓜幼苗生長有不利影響。惟如將牛糞、稻殼、金針菇類太空包廢渣及蔗渣等本土化有機廢棄物經過適當的堆肥化作用，即能改善木瓜種子發芽率及木瓜幼苗存活率，如再配合添加適量的河砂或泥炭苔等處理，更有助於提昇上述性狀。另木瓜幼苗地上部株高、根長及全株乾物重等生育性狀與堆肥介質養分含量之多寡有密切關聯。

The objective of this research was to evaluate the effects of localized organic medium (dairy waste, rice hull, bagasse, and winter mushroom waste) on the growth of papaya seedlings. The results indicated that the treatments of matured organic wastes or appllied with sand (or peat moss) could improve the seed germination rate and seedling survival rate. There was significant relationship between the nutrient contents of matured organic medium and the growth of papaya seedling, in term of plant height, root length, and plant dry weight.
