Description

Three-dimensional plant light guiding device

The invention relates to a three-dimensional plant light-guiding device, in particular to a crop that can be planted in the lower layer of a greenhouse in a greenhouse, and can also obtain sufficient sunlight, which not only makes the crop grow better, but also obtains better Yield, without the need to use artificial light sources to supplement lighting, can reduce the use of expenses, reduce the cost of crop planting, and more practical features in its overall implementation and use.

As the environment, temperature, humidity, and light required for the growth of different crops are different, if the general economic crops are planted in the open air, the crops will be subject to weather restrictions, which will affect the crop growth and even As a result, crop yields are poor, and crops are prone to death due to extreme temperatures that cannot be resisted by extreme high or low temperatures; therefore, it is often seen that farmers build greenhouses to use the greenhouses to grow various types of cash crops. It is mainly a closed environment, and the roof of the greenhouse is set up with daylighting panels, so that it can provide the set light, temperature and humidity in the greenhouse, so that the crop can obtain the best environment for growth.

With the development of the industrial and commercial industry, the area of agricultural land is gradually shrinking. In addition, planting crops in a flat way cannot effectively increase the yield of crops per unit area. Modern agricultural cultivation techniques are mostly used to increase the yield per unit area of the greenhouse. The planting method cultivates crops, and the three-dimensional planting method is mainly composed of a multi-layer structure of a planting frame, which is divided into several planting blocks for planting crops.

However, although the structure for growing crops in the greenhouse using the three-dimensional planting method can achieve the expected effect of increasing crop yield, it is also found in its actual use. Please refer to the existing schematic diagram of the use state in Figure 6, In the greenhouse (5), due to the blocking of each planting frame (51), when the sunlight is irradiated on the roof lighting plate (52) in the range of 30 to 60 degrees, the sunlight cannot be effectively radiated to each The bottom of the planting frame (51), and only the crops on the upper layer of each of the planting frames (51) can be fully exposed to sunlight. As a result, the crops on the lower layer of each of the planting frames (51) cannot receive sufficient sunlight. It affects its growth and may even reduce yield; therefore, it is usually necessary to additionally install artificial light sources to supplement the lighting of the lower crops, increase the consumption of electrical energy, and increase the overall cost of use.

The reason is that the inventors have taken this into consideration, and based on many years of rich design, development, and actual production experience in the relevant industry, research and improve the existing structure and defects, and provide a three-dimensional plant light guide device in order to achieve better practical value.
