However, Taiwan is a subtropical region and most of it is exposed to sunlight after noon or rainy season. It is easy to cause high temperature and high humidity in the indoor cultivation space, which in turn affects the growth of lily (Lilium). To improve the shortcomings of existing agricultural facilities, this experiment was conducted from April 2017 to May 2019 and selected in the Fengshan shade net house attempts to use the semi- open roof type aeroponic cultivation system to conduct a feasibility evaluation test for cut lily cultivation. The results of this experiment show that the design of this system, including set up plant cultivation chamber (3mm thickness x L1000mm x W1000mm x H700mm, Material: SUS304) and externally covered with 30mm thermal insulation cotton. In addition, the system will be equipped with a timing evaporative cooling equipment / temperature and humidity sensor combine timing spray irrigation device and the upper cover of the chamber will be designed with additional openings to enable the system to achieve rapid temperature/humidity control、instant irrigation and adjustment internal light source of the plant cultivation chamber. In system performance test result that shows, although the system at the start-up stage, the temperature, humidity, wind speed and luminosity values of the 550mm height section in the cultivation chamber can provide the initial growth and cultivation requirement of cut lily, but cut lily (Lilium 'Donato') plant growth test results show that the base fertilizer of this irrigation has not been adjusted to the optimal concentration, so it is easy to cause damage to the roots of the lily and affect subsequent growth. Therefore, although the current test has completed the performance test of aerosolized hardwood, and the feasibility of cultivating cut lily, it is necessary to improve the proportion of existing cut lily formula and improve the existing artificial spray to avoid excessive fertilization and affect lily follow-up growth.
