摘要

本試驗之目的在探討利用塑膠布覆蓋棚架及間接送風式加溫克服低溫以生產高品質的早春葡萄，以供應本省3月5月間的葡萄需求。結果顯示，只搭塑膠布覆蓋棚架時，仍不能解決因低溫引起葉片黃化並導致果實著色不良及品質低下等問題。而且，膠布會減少日照，溫度過高時有結露現象，灰黴病及露菌病發生嚴重，在在都引起果粒小及產量低等致命傷。若從11月下旬開始在塑膠布霖架內間接送風加溫，可提高產量至807kg/10a，果實之糖度為18.4 Brix%，酸度為0.68%，繼續加強研究並改善栽培管理方式可望達到提高品質之目標。

This study was conducted to overcome the low temperature and to produce high quality grape in early spring by the application of covering plastic film on the trellis and indirect heating with warm wind. The results showed that those problems such as leaf yellowing, poor coloring and low quality of berry caused by the low temperature could not be resolved by covering the plastic film on the trellis only. Furthermore, the plastic film cutted down the sunlight and gathered much dew when the temperature was too high, the grey mold and downly mildew grew fast under these conditions, they mdade the berry became small and a low yield. Indirectly heated with warm wind in the plastic film covered trellis since late November, the yield increased to 807 kg/10a and the berry had a TSS of 18.4 Brix % and 0.68% of acidity. A further study is proceeded to improve the orchard management and the fruit quality.
