Problems solved by technology

Vegetable seedling cultivation under artificial light sources is traditionally realized mainly through fluorescent lamps, but fluorescent lamps have disadvantages such as high energy consumption, short lifespan, and low light efficiency.
With the continuous development of LED semiconductor technology, there have been some reports on the use of LEDs for vegetable seedlings, such as CN201610172032.9 "A technology for growing cucumber seedlings using LED plant lights", CN201510629778.3 "A technology for growing plants using LEDs" A method for light source to promote seedling cultivation of solanaceous vegetables", CN201710060147.3 "A LED light source for promoting seedling growth", etc., all disclose related achievements of LED light source in vegetable seedling cultivation, referring to LED chips in different bands or combined with fluorescent light The powder technology is formulated into the plant growth spectrum, but for practical applications, there are still the following problems: 1. No specific spectral energy distribution is proposed for plant species. 2. A dedicated spectrum is only proposed for specific plant species. Seedling plants with poor applicability

Embodiment 1-3

[0020] Select Judi sweet pepper seeds with full grains, soak the seeds in warm water at 55°C for 15 minutes, transfer them to clean water for 8 hours, wrap them in wet gauze and place them in a thermostat at 28°C to accelerate germination, and keep the gauze warm every day. Moisten until the seeds turn white. Sow the dew-white seeds into a 72-hole seedling tray containing a substrate (peat: perlite: vermiculite = 3:1:1), 1 seed per hole, and then cover with a 1cm-thick seedling substrate after sowing. Before the cotyledons are unfolded, only water is poured, and after the cotyledons are fully unfolded, an equal amount of 1 / 2 Japanese garden test formula universal nutrient solution is added every 2 days. The day and night temperature of the cultivation environment is 28 / 20°C, the space air humidity is 65%, CO 2 The concentration is 1000ppm. The light source uses fluorescent lamps as a control, and sets 1 control example and 3 example spectra, and the light intensity is 250 μm...

Embodiment 4-6

[0027] Select the golden embryo 99-1 cucumber seeds with full grains, soak the seeds in warm water at 55°C for 15 minutes, transfer them to clear water for 8 hours, wrap them in wet gauze and place them in a thermostat at 30°C to accelerate germination, keep Moisten the gauze until the seeds are white. Sow the dew-white seeds into a 50-hole seedling tray containing a substrate (peat: perlite: vermiculite = 3:1:1), 1 seed per hole, and then cover with a 1cm-thick seedling substrate after sowing. Before the cotyledons are unfolded, only water is poured, and after the cotyledons are fully unfolded, an equal amount of 1 / 2 Japanese garden test formula universal nutrient solution is added every 2 days. The day and night temperature of the cultivation environment is 28 / 20°C, the space air humidity is 65%, CO 2 The concentration is 1000ppm.

Embodiment 7-9

[0033] Select julienne tomato seeds with plump seeds, soak the seeds in warm water at 55°C for 15 minutes, transfer them to clean water and soak for 8 hours, wrap them in wet gauze and place them in a constant temperature box at 31°C to accelerate germination, and keep the gauze moist every day until the seeds are white. Sow the dew-white seeds into a 50-hole seedling tray containing a substrate (peat: perlite: vermiculite = 3:1:1), 1 seed per hole, and then cover with a 1cm-thick seedling substrate after sowing. Before the cotyledons are unfolded, only water is poured, and after the cotyledons are fully unfolded, an equal amount of 1 / 2 Japanese garden test formula universal nutrient solution is added every 2 days. The day and night temperature of the cultivation environment is 28 / 20°C, the space air humidity is 70%, CO 2 The concentration is 1000ppm. The light source uses fluorescent lamps as a control, and sets 1 control example and 3 example spectra, and the light intensi...

Abstract

The invention relates to the technical field of plant lighting, in particular to an artificial light environment method for plant seedling raising. In the light environment, the photon number of lightwaves with the wavelength larger than 700 nm accounts for less than 3% in the whole light environment. The invention further provides a method for conducting seedling raising by adopting the light environment method. In the light environment of the management process, the artificial light environment method for plant seedling raising is adopted in the spectrum, and seedlings which are more robustthan traditional greenhouse seedlings are rapidly obtained.

Description

technical field [0001] The invention relates to the technical field of plant lighting, in particular to an artificial light environment method for growing plant seedlings. Background technique [0002] Solanaceous vegetables (tomatoes, peppers, eggplants) and melon vegetables (cucumbers, watermelons, muskmelons, bitter melons, etc.) have a long cultivation cycle, and they often need to go through the seedling process first, and the quality of the seedlings will directly affect the planting process. Post-vegetative growth and reproductive growth. Therefore, cultivating healthy seedlings of vegetables is a key factor to ensure the high yield of solanaceous fruits and melon vegetables. The traditional field seedling raising methods and greenhouse seedling raising are often limited by some natural factors. Insufficient light leads to weak growth of seedlings, which can no longer meet the market's demand for vegetable seedlings. With the emergence of artificial light plant fact...
