Early plant factory construction scale is little, mainly limits in the laboratory, and plants crop variety singleness, adopts the phytotron to control, and the running cost is higher. Plant factories begin to develop from the first 70 th to the middle 80 th of the 20 th century, and enterprises in many countries such as the United states, Japan, England, Norway, Greece, Libiya, etc. invest enormous capital in a number of times, and develop key technologies in conjunction with research institutions.

In 1961, LEDs and the like are invented, and have the photoelectric advantages of low energy consumption, high luminous efficiency, low heat generation, specific wavelength, pure light color and the like. With the continuous progress of LED technology, energy-saving LED light sources special for plants are increasingly popularized.

For example, the light intensity of the iced vegetables cultivated in the transparent light-transmitting glass room can be slightly weaker than that of the iced vegetables cultivated in the full-shading cultivation room based on the external supplementary lighting condition.
According to a preferred embodiment, the environmental parameters can be adjusted for the light-providing conditions in the light environmental quality control plan in the manner of equation 1:
F=Q1*M1+Q2*M2+...Qn*Mn

Fluorescence is used to generate the excited light. The fluorescence provided at the plant roots is used to recover and reuse the light that is irradiated to the bottom of the plant without being absorbed by the plant. The fluorescence is applied to the fluorescent plate in a direction toward the light emitting part 100. The fluorescent plate utilizes the light source generated by the light emitting part 100 in multiple levels, so that the aims of reducing irradiation dead angles and collecting signals by using light rays without energy supply so as to monitor the environment and plants are fulfilled.
The light signal emitted from the fluorescence can be used for monitoring the plant state or supplementing the light signal on the back of the plant leaf. A part of light emitted from the fluorescent plate irradiates the back of the plant leaf or other tissue parts due to the shielding of plant tissues and is absorbed; the other part passes through the plant tissue gap and finally returns to the side where the light emitting part 100 is disposed, thereby being sensed by the light sensing member disposed near the light emitting part 100.
