Embodiment 1

[0031] Embodiment 1. Implementation structure of light source equipment:

[0032] (1) Functions of each part

[0033] 1) LED lighting fixtures (other light sources can be used)

[0034] It is the luminous main body, which is divided into four types. The brightness of each lamp can be adjusted in 256 brightness levels. Each luminous pixel is composed of high-brightness light-emitting diodes. The detailed parameters are as follows:

[0035] Table 1 LED lighting parameters

[0036]

[0037] (Note: Each pixel consists of 2 super bright LEDs)

[0038] 2) Control switch

[0039] It is used to control and adjust the working parameters and working status of the luminous lamps. There are four buttons in total.

[0040] ①Set / OK button

[0041] Press it for the first time to enter the control setting state, the setting function indicator light is on, press it again to confirm the current value, and exit the setting state, the setting function indicator light is off.

Embodiment 2

[0056] Embodiment 2, spectrum test and growth effect test of Momordica grosvenori test-tube plantlets

[0057] 1 Materials and methods

[0058] 1.1 Growth effect test of Luo Han Guo test-tube plantlets under different wavelengths of light

[0059] Inoculate the aseptic materials of the test tubes of Luo Han Guo Qingpi varieties on the same medium (MS+BA0.2+NAA0.02), and culture them under blue, yellow, red and fluorescent lamps respectively. Adjust the illuminance of the luminaire by adjusting the button. After the size is as consistent as possible (about 800lx), the light is illuminated for 12 hours a day. 20 vials per treatment. After cultivating for a certain period of time, take 5 bottles to observe the growth of the seedlings, including plant height, leaf number, fresh weight, etc.

[0060] According to the growth situation of the seedlings in the above test, the illuminance of the LED light source was adjusted to the maximum, and the illuminance was respectively blue ...

Embodiment 3

[0095] 1. Use the light source wavelength range between 300-800nm ​​(simulating the composition and wavelength range of sunlight) to test the absorption spectra of the three different sunshine types of rice, mangosteen and calla lily. The selected leaves are all grown The upper and middle leaves of young plants; the directly measured data is the transmission spectrum of light passing through the leaves, and the absorption spectrum of the leaves can be calculated from the transmission spectrum. The measurement results show that the absorption spectrum of mature leaves of plants has two strong absorption ranges: one is between the wavelength 380-500nm, including the UV-B, UV-A region and blue light region; the other is the wavelength 660-680nm Left and right, a very narrow area of ​​red light. There are only slight differences in the absorption spectra of different plants, mainly in the absorption intensity.

Abstract

The invention discloses a method for promoting plant growth by illumination, in particular to designing a light source product with universal meaning according to the spectrum demanded by plant growth, therefore the method of supplementary illumination of plants in raising seedling of plastic tents and factories is found. The method comprises the following processes: (1) seedling preparation; (2) confirming the absorption spectrum of the plants; (3) testing the photosynthesis under different light qualities; (4) comparing and analyzing the experiments so as to confirm the light absorption of different plants; (5) designing light source equipment; (6) supplementary illumination is carried out to the plants. In the method, spectrum test equipment is used for testing the plants with different types; the light sources with different wavelengths are chosen and made according to the absorption spectrum of the plants, therefore the pertinence and efficiency of the light source can be improved efficiently. The bud ratio and the survival ratio can also be improved efficiently, the seedling state can be shortened, the biomass of seedlings can be increased, and the height of the seedlings and the number of leaves are promoted for increasing, thus shortening the growth period of the plants efficiently and improving the efficiency and benefit during raising seedling and growth.

Description

technical field [0001] The invention relates to a method for promoting plant growth by using light, in particular to design a light source product with universal significance according to the spectrum required by plant growth, so as to find a method for supplementing light for plants in industrial seedling and seedling raising in greenhouses. Background technique [0002] Light is an important environmental factor in plant growth and development. It not only provides the energy needed for plant photosynthesis, but also provides the information that plants need to adapt to the environment for normal growth and development. Through scientific research, it has been found that green plants have a selective demand for light, mainly concentrated in the blue-violet light region of 400-460nm and the orange-red light region of 600-700nm, among which, blue and red light can promote photosynthesis of plants; Ultraviolet light, red light, and near-infrared light can regulate the growth ...
