摘要

堆肥含有充足的養分及豐富的微生物，若與物理性良好的填充資材混合調製，可望成為優良的本土化育苗介質。為研究其可行性，本計畫以市售粉狀一般堆肥29種及其他有機資材6種為材料，進行調製與試驗。結果顯示，有5種堆肥可以直接作為花胡瓜育苗介質，有2種堆肥可以直接作為甜椒育苗介質，育成率高達90%以上，且苗株生育顯著優於商用介質。另有7～25種堆肥，需與其他資材，以不同比例混合後，才有應用價值。其餘有2～17種堆肥，則不能用於育苗介質。因此，直接以堆肥作為育苗介質，或混合其他資材作為介質，應具有可行性。另外，六種資材中以泥炭苔、椰子屑、蛭石、及木屑等四種之育苗效果最佳，而粗糠及蔗渣之效果則較差。以經濟成本來評估，則以木屑及椰子屑成本最低，最具有開發潛力。而不同的木屑中，又以尤加利樹、蓮霧樹、及柳胺木的效果較優，相思樹則較差。

Compost contains mineral nutrients and vital microorganisms. A mix of compost amended with locally-available additives could potentially be used as a superior seedling media. To evaluate the potential of compost mix used for seedling media, a methodology of preparing effective compost mixes from 29 commercial compost products incorporated with six locally-available additives, were investigated. The six additives used were coconut husk, nitantai, vermiculite, sawdust, rice husk, and bagasse. Growing tests were conducted on each of the prepared compost mix. The test plants used were cucumber and green pepper. If a compost mix exhibited a 90% healthy growth rate during the growing test, that particular compost mix is a satisfactory potting media. The results indicated that 1) two to five commercial compost products can be used as potting media without amendment. Furthermore, seeding growth in these compost products are better than in the commercial potting media; 2) seven to twenty five compost products can become effective potting media after they are amended with proper additives; 3) two to seventeen compost products, which have been amended with any one of six additives, can not be used as an effective potting media; 4) compost mix amended with either peat moss or coconut shreds, or vermiculite, or sawdust are most effective, while the compost mixes amended with either rice hull or bagasse are least effective when used as potting media; 5) the compost mixes prepared with sawdust or coconut husk exhibit excellent potential as potting media because the preparation costs are the lowest; and 6) sawdust obtained from yukiali tree, wax apple tree, and liuan tree are effective additives but shiansu tree's sawdust is not.
