設施環控在瓜果類生產之應用及LED在草莓生長發育之影響

Abstract

利用環控溫室提高濕度，空氣排風增加，降低熱焓， 在高日照下，早上7時至下午6時， 室內溫度高，越早加濕通風，可有效使設施環控得到良好控制。在夏季高溫之環境，噴霧開3分鐘，停2 5分鐘、上方側風扇2 4 ” x 2組及溫控風扇36”x2台，用電量約23度電，內外溫差最大達6.5℃(室內溫度濕度31.3℃、 81.3%，室外溫濕度37.8 ℃、濕度49.8%)，但須注意高溫高濕造成植株病害發生所需的防治作業。建置人工介面控制並監控溫溼度及二氧化碳變化之草苺植物工廠。此系統仍可再擴充層架，以進行大量草苺涼溫育苗。在可控制的環境下，配合涼溫、長日及二氧化碳補充，可促進草莓苗營養生長，縮短育苗期，減少病蟲害及降低生產成本。配合低氮及短日涼溫處理，可促進花芽分化整齊度，如配合LED補光，則可增加定植前馴化能力的潛力。 The result indicated hat sprinkling for 3 minutes and off for 25 minutes with two 24”overhead fans and two 36” side fans could decrease the temperature,6.5℃, compared that of greenhouse with outside temperature (31.3℃ and 1.3% humidity in greenhouse, while 37.8 ℃, 49.8% humidity in outside). We suggested that sprinkling was started from the temperature increasing at 7 o’clock in the morning and stopped at 2 o’clock in the afternoon. The total electricity consumption was about 23 KWH per day under this experiment. In addition, the suitable pesticide control was indeed when the disease or pest were occurred. In this study, the strawberry plant factories have built. This could control and monitor the temperature, humidity and carbon dioxide by people-machine interface. Extend the number of the bench on the growth factory was used for mass seedling cold temperature treatment. Under control environment, which could improve the vegetated growth, decreased the disease, insect pest, lower product cost and shorter nursery period by cold temperature with long day-length and carbon dioxide enrichment. Low nitrogen concentration with short day-length and cool temperature could improve the uniformity floral bud induction. The LED supplements has the potential of which increased the acclimation before planting. The results of this study could be used as reference for strawberry factory manufacturing in the future.
