摘要

本研究係利用栽培土壤經添加不同比例之椰纖；並與聚乙烯醇(PVA)均勻混合；並經由熱定型處理製成不同混合比例和含膠量的實驗樣本；進而測試各項物理和化學性質；以取得最適合栽培的條件；而最終之目的在取代目前之栽培介質；由實驗結果顯示；添加50%之椰纖；並以2%聚乙烯醇均勻混合之樣本；其含水率、保水率、孔隙度、三相體積分率、Ph值均較好；最適宜用於土壤栽培之上。

This research is using soil and by adding Polyvinyl Alcohol Fiber and Coir- Fiber in different percentage, samples are made in different percentage and contained percentages glue’s quantity by compressing in to a fixed volume by high temperature. According to physical and chemical tests, we suppose to find the best growth condition. At least we suppose to replace the soil culture medium. The research shows when adding coir-fiber 50% and PV A fiber2%, it is suitable for soil culture. The coir fiber percentage effects volume reducing percent, water losing percent, three kinds of capacity percent and pH value.
