Abstract:	本實驗以具有高孔隙度3D 主體結構骨架之天然絲瓜纖維作為無土栽培介質之基材，並利用氫氧化鈉水溶液對其進行鹼處理改質以增加親水性。文中探討不同濃度之海藻酸鈉(3%、5%、7%)與氯化鈣交鏈處理後對絲瓜無土栽培介質含水率的影響，並利用pH 計和EC 計測試絲瓜栽培介質之酸鹼度值及電導度值之影響。結果顯示海藻酸鈉濃度在5%時樣本之含水率最高，鹼處理在6 %時樣本則達到飽和含水。而隨鹼處理濃度提升，絲瓜無土栽培樣本的含水率亦隨之提高。 In this experiment, as soilless culture medium of the substrate having a main structural skeleton of the high porosity 3D loofah natural fibers, and the use of aqueous sodium hydroxide to the alkali treatment is modified in order to increase hydrophilicity. Of different concentrations of sodium alginate (3%, 5%, 7%) treated with calcium chloride crosslinking loofah soilless culture medium moisture and pH of the cultivation medium pH meter and EC meter test loofah value and electrical conductivity values. The results show that sodium alginate concentration of 5% when the water content of the samples of the highest rate of alkali-treated samples in the 6% saturated aqueous. With the concentration of alkali treatment to enhance loofah soilless culture samples moisture will improve.
