中文摘要 | 新社地區是臺灣枇杷的主要產地,夏秋季的高溫使枇杷早花之有效性低,導致產 期過於集中。本研究於臺中新社地區枇杷園進行棄蔭網和噴霧處理的降溫試驗。研究結果指 出,就新社地區的氣候條件而言,若於9∼10月間使用0.78Lm�颳r 的噴水密度並配合70%遮 蔭處理,則每日上午9時至下午4時之間,枇杷植叢葉溫降至25℃以下的比例可達80%以下, 應可減少該期間高溫對早花發育的障害,有幫助產期分散調整的功效。 |
英文摘要 | Shinse area is a major Loquant produce area in Taiwan. However,the span of harvesting date is very narrow as a result of impaired inflorescence development by high temperature in early autumn. In this study, high-temperature alleviating techniques, such as shading and misting, were applied in a loquat orchard in Shinse area. The results indicated that combinations of misting at density of 0.078L�颳r and 70% shading could reduce the canopy temperature to 25℃ or lower for more than 80% time among 9 a.m. to 4 p.m. during September and October. This may alleviating the high temperature stress of loquat and have usefulness to harvesting date adustment. |
