摘要: | 本研究旨在探討階段性調整光質與光強 (光配方) 對香波綠萵苣生長與電能消耗之影響,使用AgroONE表型體設備及其燈管 (辰明智能,台灣) 為光源,於全人工光型植物工廠進行栽培,嘗試找出最適合香波綠萵苣生長之光配方,並以電力產能 (EY) 、光子產能 (PY) 、地上部鮮重與作物外觀及型態作為生產效能之量化指標及評斷標準。
試驗設計分為三部分:1. 不改變光譜只調整晝白光強度 (Natural White, NW)。2. 隨著株高的增加調降光強,並於栽培中同步增加遠紅光 (Far Red, FR)。3. 探討遠紅光的最適當給予週數與光強度。 在不添加FR只使用NW光的情況下,根據株高調降光強度處理組之電力產能 (EY為84.2 g·kWh-1) 得以超越未調光之對照組 (EY為80.3 g·kWh-1)。添加FR後鮮重與株高皆明顯提升,不過添加兩週之FR導致莖部徒長。於第四週補充23 µmol·m-2·s-1的FR,單株地上部鮮重與EY 均優於第三或第五週添加之處理組,整體賣相也較佳。24小時給予FR並縮短NW的光期證明於第四週每日添加24小時FR是可行的,且在第五週只補上10 µmol·m-2·s-1之FR,香波綠萵苣得以在不過度莖部徒長下,得到良好之地上部鮮重及EY,分別為181.9 g·plant-1及98.1 g·kWh-1,優於不調光對照組的125.6 g·plant-1及80.3 g·kWh-1。 本研究針對香波綠萵苣嘗試多種光配方,並延伸探討不同處理組之結果,找出較高生產效能 (產能與節電) 的栽培模式。 This study aims to investigate the effects of staged adjustment of light quality and light intensity (light recipe) on the growth and power consumption of Ice Queen Lettuce. AgroONE phenotype equipment and its LED (Agromeans, Taiwan) were used as the light source. Cultivate in a plant factory with artificial light, try to find out the light recipe that is most suitable for the growth of Ice Queen Lettuce, and use energy yield (EY), photon yield (PY), shoot fresh weight, crop appearance and shape as the production efficiency and evaluation criteria. The experimental design was divided into three parts: 1. The diurnal light intensity was adjusted without changing the spectrum (Natural White, NW). 2. Decrease the light intensity as the plant height increases, and simultaneously increase the far red light during cultivation. 3. Discuss the most appropriate administration cycle and light intensity of far-red light. In the case of using only NW light without adding FR, the power production of the light intensity treatment group adjusted according to plant height (EY is 84.2 g·kWh-1) can surpass that of the control group without light adjustment (EY is 80.3 g·kWh-1). After adding FR, the fresh weight and plant height were significantly increased, but the addition of FR for two weeks resulted in leggy stems. Supplemented with 23 µmol·m-2·s-1 of FR in the fourth week, the fresh weight and EY of the shoots per plant were better than those added in the third or fifth week, and the overall appearance was also better. 24 hours of FR and shortening the photoperiod of NW proved that it is feasible to add 24 hours of FR daily in the fourth week, and only 10 µmol·m-2·s-1 of FR was supplemented in the fifth week, and the Ice Queen Lettuce could prevent from excessive stem growth, good shoot fresh weight and EY were obtained, which were 181.9 g·plant-1 and 98.1 g·kWh-1 respectively, which were better than 125.6 g·plant-1 and 80.3 g kWh-1 of the non-dimming control group. This study tried a variety of light formulas for Ice Queen Lettuce and extended the results of different treatment groups to find out the cultivation mode with higher production efficiency (production capacity and power saving). |
