Description
Technical Field
The invention relates to a plant growth illumination device and a control method thereof, in particular to a plant growth illumination device for providing prevention and control of plant diseases and insect pests for workers in a plant illumination environment and a control method thereof.
Background
In the natural environment, plants perform photosynthesis and development and growth by acquiring light components with effective wavelengths in sunlight. However, the natural environment is diverse and has risks of insect damage and the like. Therefore, plant factories that plant plants in closed spaces such as indoor spaces and simulate natural light by artificial lighting lamps have been gradually developed in recent years, and various large enterprises including philips, osram, GE, siemens and the like have entered this field.
Not all of the light of the various wavelengths contained in natural light can be utilized by plants, and essentially only blue and red light can be absorbed by plants. In particular, blue light B (e.g. 460nm) can help the growth of plant roots, with the most significant effect on early plant; the red light R (for example 660nm) is beneficial to the stem and leaf, flowering and fruit growth of plants; ultraviolet FR (e.g., 730nm) is useful for controlling plant flowering and in vivo nutrient synthesis. According to the species and the growth stage of the plant, the optimal illumination environment for the plant can be obtained by setting the appropriate wavelengths of the red light and the blue light and the red-blue ratio (B/R) between the red light and the blue light; the ultimate goal is to obtain high and stable yield of plants and high and stable nutritional ingredients, while achieving insect control and other effects.
For example, in "lei xiao et al. effect of different red and blue LED combined light sources on watermelon seedling growth and physiological parameters [ J ]. chinese cucurbita pepo, 2015, 28 (3): the following are described in the documents 14-17 ": for watermelon planting, a fluorescent lamp is used as a reference (the illumination intensity is 150 mu mol. m-2s-1), and the influence of LED combined light sources (7: 1, 7: 2 and 7: 3) with different red light and blue light ratios (R/B) on the growth and physiological parameters of watermelon seedlings under the same illumination intensity is discussed; the results show that the stem renting degree, the fresh quality, the dry quality and the strong seedling index of the watermelon seedlings under the red and blue LED combined light source are all increased, wherein the effects are particularly remarkable under the condition that RB is 7: 3.
Disclosure of Invention
(problem to be solved)
However, the existing LED plant growth lamps are all plant LED growth lamps manufactured by mixing a white light LED light source or a red blue light LED light source or a red, blue and white LED light source. Because the red light has low luminous efficiency, the power of the plant LED growing lamp is high and the cost is increased sharply in order to meet the spectrum and the illumination intensity required by a plant photosynthetic pigment system.
The ratio of the number of red to ultraviolet photons (R/FR) in the spectrum has a significant effect on plant configuration and plant height regulation. Because the total quantity of the red LEDs and the blue LEDs is far more than the quantity of the infrared LEDs, the ultraviolet light is difficult to be uniformly distributed in the design of the lamp, and the plants are difficult to be uniformly irradiated.
When the LED plant growth lamp is in the red light and ultraviolet light working state, a user who carries out cultivation operation bears psychological burden because the user is in the red light and ultraviolet light environment for a long time. In addition, under red and ultraviolet light environments, it is difficult to determine the growth state of plants and the like by visually observing the colors of plants due to poor visibility, and thus workability and efficiency of plant cultivation are reduced.
