Plant illumination adjusting method and plant illumination adjusting device

Abstract

The invention provides a plant illumination adjusting method and a plant illumination adjusting device. The plant illumination adjusting method comprises the following steps: collecting natural illumination intensity of each planting area in a greenhouse; comparing the natural illumination intensity of each planting area with a corresponding preset illumination intensity range of each planting area; performing illumination supplementing operation on at least one planting area when the natural illumination intensity of at least one planting area is less than the lowest threshold of the corresponding preset illumination intensity range of the at least one planting area; and performing shading operation on at least one planting area when the natural illumination intensity of at least one planting area is larger than the upper threshold of the corresponding preset illumination intensity of the at least one planting area. Through a technical scheme of the invention, the illumination intensity in the greenhouse can be in an intensity range applicable to plant production; meanwhile, corresponding illumination adjusting operation can be performed in terms of different planting areas with different planting conditions; thus, planting efficiency and application efficiency of the greenhouse are further enhanced.

Description

technical field [0001] The present invention relates to the field of planting, in particular to a method for adjusting light of plants and a device for adjusting light of plants. Background technique [0002] In related technologies, according to the demand for red and blue light in each growth stage of plants, set red and blue light thresholds, detect the red and blue light intensity in the plant growth environment, and judge whether supplementary light is needed by comparing it with the corresponding red and blue light thresholds And precise fill light amount, if fill light is required, calculate the input current of the corresponding fill light group according to the required fill light amount, so as to accurately control the brightness of the fill light group, and realize intelligent and precise fill light on demand, if no fill light is required, Then turn off the supplementary light group, there are the following defects: [0003] (1) There are different types of crops...

AI Technical Summary

Problems solved by technology

[0003] (1) The types and growth stages of crops in different areas of the greenhouse are different, and different types of crops and different growth stages of the same crop have different requirements for light. Using the same light supplement mode cannot achieve the best light supplement effect;

[0004] (2) Only the supplementary light function can be realized. If the ambient red and blue light are stronger than or equal to the corresponding red and blue light thresholds, it is judged that supplementary light is not needed, and excessive light will also affect the normal growth of plants.
