Description

Three-dimensional plant light guiding device

The invention relates to a stereoscopic plant light guiding device, in particular to a crop which can be planted in the lower layer of the planting rack in the greenhouse can also obtain sufficient sunlight to not only make the crop grow better and obtain better. The output, without the need to use artificial light source to supplement the light, can reduce the cost of use, reduce the cost of crop planting, and increase the utility characteristics in its overall implementation.

According to the different environments, temperature, humidity, and illumination required for different crop growth, if the cultivation of general economic crops is carried out in an open-air manner, the crops will be weather-limited, causing crop growth to be affected, even Leading to poor crop yields, and crops are prone to death due to the inability to withstand extreme temperatures such as extreme heat or cold temperatures; therefore, it is often seen that farmers build greenhouses to use the greenhouse to grow a variety of cash crops. Mainly a closed environment, and the greenhouse roof is constructed with lighting panels, so that the set light, temperature and humidity can be provided in the greenhouse to enable the crop to obtain the optimal environment for growth.

With the development of the industrial and commercial industry, the area of agricultural land has been gradually reduced, and the planting of crops in a flat manner has not been able to effectively increase the crop yield per unit area, making modern agricultural cultivation techniques use three-dimensional for the purpose of increasing the yield per unit area of the greenhouse.
