Abstract

本試驗將省產高經濟價值之孟宗竹、巨竹、馬來麻竹及桂竹,以鎳鹽、銅鹽、鉻鹽等保護藥劑予以處理,冀能研製出保有綠色竹青且耐久性佳之高品質竹材,拓展竹材之使用領域。竹材經保護藥劑處理後,以色差計分析比較竹青顏色之變化,試驗結果顯示:竹青之綠色效果隨著保護藥劑濃度與處理時間增長而增加;孟宗竹竹青之綠色效果以保力定K-33、硝酸鎳、硫酸銅等處理為佳;巨竹、馬來麻竹以保力定K-33處理,竹青具有最佳之綠色效果;桂竹經保護藥劑處理後竹青顏色偏黃,綠色效果較差;以保力定K-33與硝酸鎳或硫酸銅混合處理可以改善孟宗竹竹青之明度與彩度;以硝酸鎳與硫酸銅混合處理竹青顏色最綠;孟宗竹對於保護藥劑的適用性最優,巨竹次之,馬來麻竹與桂竹較差。
