本研究以回收木屑為主要製備材料，藉由混合壓克力樹酯、椰子油發泡劑及聚丙烯酸鹽，經微 波加熱技術合成無土栽培基材。根據實驗結果顯示，回收木屑及水性壓克力樹酯於混合比例約 1:2時，具最佳成型效果，若椰子油發泡劑濃度維持8%時，無土栽培基材能具有最佳發泡孔 洞形態及孔洞量，以回收木屑所製成之無土栽培基材含水率為334.78%、保水率可達40小時、 孔隙率為53.50%。

In this study, recycled wood chips were used as the main preparation materials. By mixing acrylic resin, coconut oil foaming agent and polyacrylic acid salt, micro-heating technology used by synthesize soilless culture substrate. As the results, the recovery of wood chips and water-based acrylic resin in the mixing ratio of about 1: 2, with the best molding effect. If the concentration of coconut oil blowing agent keep at 8wt%, soilless culture substrate can have the best foaming pattern and pore volume. The moisture content of the soilless culture substrate was 334.78%, and the water retaining effect was 40 hours, and the effective porosity was 53.50%.
