Description
Technical Field
The invention relates to a server-based plant growth illumination device for preventing and controlling plant diseases and insect pests and a control method thereof, in particular to a server-based plant growth illumination device for preventing and controlling plant diseases and insect pests for workers in a plant lighting 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; far-red FR (e.g. 730nm) is beneficial 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.
The use of ultraviolet light as a pest trapping device is known in the art. However, researches show that the black light lamp emitting ultraviolet light induces the difference between the number of the excessive beneficial insects and the harmless insects and the number of the harmful insects which are less than the number of the beneficial insects, so that the application effect of the black light lamp is poor, the biodiversity is destroyed, and the expected target is not achieved. In developed countries such as the united states and japan, black light lamps and hybrid light lamps (incandescent lamps) have been mainly limited in use for agricultural pests in the last 70 th century by pest control surveys and reports, and are mentioned less as a control tool, even are banned.
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. Furthermore, the red-blue light quantum density ratio needs to be adjusted when different plants are in different growth stages. In the photosynthetic LED light source integrally formed by packaging, the light-quality proportion of red light and blue light is certain and cannot be regulated.
In the plant production process, diseases and insect pests are often accompanied. It is known that a large amount of insects can be trapped and killed by using ultraviolet rays of 200 to 380 nm. However, since light in this wavelength range damages DNA and human retina, there is a problem that it is harmful not only to fungi but also to biological safety of human. Research shows that the compound eyes of the nocturnal moths are in 'bright adaptation' state in daylight, also called 'bright eye' state, and in 'dark adaptation' state in nighttime, also called 'dark eye' state, while the feeding, mating and spawning activities of the common nocturnal moths are performed in the 'dark adaptation' state in nighttime, when enough green illumination intensity is given at night, some moths are still in the 'bright adaptation' state, for example, the shielding pigments of the cotton bollworm adult compound eyes still cover the compound eyes like in daytime, so that the green lamps can influence the biological habits of the nocturnal moths and play a role in controlling the density of pests.
