中文摘要 | 本試驗目的在探討野生茶樹於遮蔭環境下的反應及其適應性,做為栽培野生茶樹生產模式的依據。試驗處理分為70%、50%黑色遮蔭網長期遮蔭區及無遮蔭區(CK)。由不同遮蔭區之野生茶樹生育、化學成分及製茶品質變化的結果顯示,無論50%或70%遮蔭處理,其茶樹存活率、樹高、葉長及寬度與葉面積、葉片數均高於無遮蔭區,葉片厚度則呈現相反之趨勢。由此可知幼苗期野生茶樹於遮蔭設施之栽培管理呈現較佳的生育狀況。架設高架式水平黑色遮蔭網設施栽培,在夏季能夠達到降低氣溫且減少光度,冬季期間尚有保溫的效果。經長期遮蔭處理之野生茶樹樹冠擴展及產量高於無遮蔭區,製茶品質同樣呈現較佳之趨勢。顯示在遮蔭環境下有利於野生茶樹的生育及提高製茶品質。無遮蔭區之芽葉及成品之可溶成分、多元酚、兒茶素、可溶糖含量高於遮蔭區,且達顯著的差異,不同季節有相同的趨勢。咖啡因含量則因季節而呈現不同的變化。胺基酸含量在茶季間有不同的變化趨勢,整體而言,以無遮蔭區之胺基酸含量高於遮蔭區。 |
英文摘要 | For the purpose of establishing economic culture production model of wild tea plantation at plain, long shading by artificial black net were used to modify cultivating environment to understand response and adaptation of wild tea tree. The experimental treatments included 70%, 50% shading and no-shading (CK). The results were summarized as follows: Both the survival ratio of 50% or 70% shading treatments were higher than that of the no-shading treatment in wild tea seeding period. Tree height, leaf length, leaf width, leaf area and leaf number had the same trend. But the leaf thickness was thinner in shading treatment. Under the shading canopy, the air temperature and light intensity were decreased in summer tea season, while air temperature keep warmer in winter tea season. The extension of wild tea canopy and shoot yield of shading treatment were higher than that of the no-shading treatment. The manufacture quality also had the same trend, which suggested wild tea tree grows was better in the shading environment. However, the soluble solid, polyphenol, catechin, soluble sugar content of fresh tea shoot and made tea of no shading were significantly higher than that of the long-shading treatment, and the same trend appeared in the different tea seasons. The caffeine and total free amino acid content varied differently among tea seasons. |
