Abstract：

    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.
