中文摘要 | 國內文心蘭在遮蔭網室內進行栽培,由於此種設施未有環境調節裝置,無法調整 內部微氣候,因此花卉產期集中,無法全年供應市場。在此研究使用機械風扇與灑水噴頭之 間歇作業,用以調整內部微氣候。結果顯示國內慣用的晨間灑水灌溉方式在夏季對設施內部 產生了高溫高濕現象。僅利用灑水而未配合通風作業,設施內部氣溫無法降低,而且相對濕 度接近飽和。以間歇式灑水配合通風,可使設施內部氣溫低於大氣溫度。在 1.2m/s 風速下 之文心蘭植株。 其偽莖溫度則接近 28 ℃。三種灑水技術中,以 30sec/7min30sec 之作業 技術,對於此特定設施可以得到最佳之蒸發冷卻效率。此降溫技術對文心蘭之花期調整效果 已有改善。此技術可應用於其他文心蘭設施以得到最佳降溫作業。 |
英文摘要 | Oncidiums are planted in the shading nets in Taiwan. Because the protected structure was lack of controlling equipment of inside microclimate, the production period was limited in special season. In this study, mechanical fans and sprinklers with interval operations were applied to adjust the internal micro-environment of shading nets. The traditional method that sprayed water without ventilation induced the higher humidity and higher temperature. The interval spraying and mechanical ventilation can keep the interior temperature lower than outside air temperature. The plant temperature of Oncidiums can be reduced to 28℃ at the 1.2m/s wind velocity. The on/off spraying technique with interval function of 30sec/7min30sec had the best evaporative cooling efficiency among the three functions for the specific shading nets. Similar technique can be applied to others' shading nets of Oncidiums to obtain the adequate cooling operation. |
