中文摘要 | 試驗以 LED10R (10W紅光)、7R3B (7W紅光混合3W藍光)、5R5B (5W紅光混合 5W藍光)、5R2B (5W紅光混合 2W藍光)及23W 110V、23W 220V黃光省電燈泡為對照進行照度量測。燈泡之架設高度為 1.8 m,量測燈下及燈下不同水平距離之照度。 10R (10W紅光)的照度高於 7R3B (7W紅光混合 3W藍光),更高於5R5B (5W紅光混合 5W藍光)。藍光對照度之貢獻度遠不及紅光。 10R於燈下之照度高於 23W 110V或23W 220V黃光省電燈泡,但是在燈下水平距離 2.5 m處,則 10R之照度低於 23W 110V及23W 220V。於3 m邊長之正方形4頂角架設燈泡,並於夜間 10 pm ~ 2 am電照4小時。不同燈泡下之 ‘芬蘭小粉 ’到花日數, 10R於燈泡正方形中心點為 54日。其餘燈泡正方形中心點則為 47~51日,相差為 3~7日。 ‘白天星’之到花日數則在 42日至44日之間,其 10R之紅光抑制開花之效果仍比其他各組佳,其次為23W 220V省電燈泡及 LED 7R3B。‘黃精競’之到花日數,亦以 10R之結果最好,其次為23W 110V及23W 220V省電燈泡。 |
英文摘要 | LED lights 10W red (10R), 7W red with 3W blue (7R3B), 5W red with 5W blue (5R5B) and 5W red with 2W blue (5R2B) were tested for flowering inhibition of Chrysanthemum. The 23W 110V and 23W 220V yellow energy saving blubs were used as control. The height of light installation was 180 cm. Light intensity of 10R was higher than 7R3B and 5R5B. The input of light intensity of blue light was less than red light. Light intensity on ground under the 10R LED was higher than 23W 110V and 23W 220V blubs, while less than same blubs at the 250 cm away in horizontal. Light bulbs were installed on the 4 corners of a 3 m square and lighting was setup from 10 pm to 2 am. For variety “Fen-Lan-Xiou-Fen”, days to flowering of square center of 10R treatment was 54 days, while was 47 - 51 days of the other bulb treatments. For variety Bai-Tein-Xin, days to flowering was from 42 - 44 and the inhibition efforts of 10R treatment was better than others. For variety “Huang-Gin-Gin”, it was similar with the other two varieties. The result of 10R was the best. |
