  為探討‘麻豆文旦’果園覆蓋泰維克(Tyvek®)反光布對果實品質之影響,本試驗分別在麻豆文旦果實採收前一個月及兩個月進行地面覆蓋,以提高樹冠光合作用及控制土壤溫度、水分。試驗結果顯示,覆蓋Tyvek®反光布,可減緩中午地表溫度的劇烈變動,果皮色澤有較高明度(L值)、彩度(Chroma)及色相角度(hue angle);同時能增加樹冠外層的葉綠素a、葉綠素b及總葉綠素含量。且以採收前兩個月覆蓋Tyvek®反光布者明顯較對照組提高果實可溶性固形物、果汁率與糖酸比。

關鍵詞:麻豆文旦、果實品質、泰維克、覆蓋


Effect of Tyvek® Mulch on Improvement of Fruit Quality of ‘Matou Wentan’ (Citrus grandis Osbeck cv. ‘Matou Wentan’)

Chang, C. C., C. S. Chang and D. L. Lin

Abstract

  To investigating the effects of Tyvek® mulch on the fruits quality of ‘Matou wentan’. This study improved the canopy photosynthesis and controlled the soil moisture by covered Tyvek® under ground in the orchard one and two month before harvested. The result showed that Tyvek® mulch can stabilized the soil surface temperature, increased the total chlorophyll and chlorophyll a,b content of outer canopy, The color of fruit rind higher L, chroma and hue angle value than control. Compare to control, the treatment of Tyvek mulch two month before harvested, it showed higher total soluble solids (TSS), percentage of juice, and ration of total soluble solids (TSS) / titratable acidity (TA).

Key word: Matou wentan, Fruit quality, Tyvek®, Mulch
