Description

Technical Field

[0001] The present invention relates to the technical field of plant cultivation, in particular to a plant cultivation box capable of adjusting light wavelength bands. Background Art

[0002] At present, there is a huge demand for agricultural products in China, and the problem of arable land is becoming increasingly serious. Based on this situation, soilless cultivation technology has developed rapidly in recent years, and plant culture cabinets are an important equipment for it. However, the common plant culture cabinets currently use simple lighting to simulate the sunlight environment to enable plants to photosynthesize. However, simply simulating the simplest light cannot achieve the best photosynthesis in plants. This is because plant photosynthesis relies on light and pigments, and the absorption spectra of various pigments are also different. For example, chlorophyll a and b mainly absorb red, orange, blue, and purple light, carotenoids absorb blue-violet light, and green light is the color light with the lowest absorption rate of various pigments. In addition, different plants have different light sensitivities at different production stages. Plants need to absorb different types of wavelengths of light. Therefore, simple light cannot make plants grow in the best state.

[0003] The inventors discovered during their research that the plant incubators in the prior art have at least the following disadvantages:

[0004] During the plant growth process, the lighting effect is not adaptively adjusted according to the plant's growth stage, resulting in low plant growth efficiency. Summary of the Invention
