Problems solved by technology

[0004] The domestic plant light source market has developed rapidly in recent years. Most of the plant light sources of LED manufacturers have not done in-depth research on the spectrum with the highest plant utilization efficiency. Generally, full-visible light continuous spectrum broadband LED equipment is used as plant light sources. The lower spectrum is wasted, and the efficiency of converting electrical energy into phytochemical energy is reduced, resulting in a waste of energy

Embodiment 1

[0069] This embodiment provides a method for promoting the growth of tomato seedlings. The method for promoting the growth of tomato seedlings includes providing artificial light sources to the growing tomato seedlings to promote the growth of tomato seedlings, specifically:

[0070] In plant factories with artificial light sources as the main light source, the artificial light source provided in the tomato seedling stage is 85% red light and 15% blue light according to the light quality spectrum integral percentage;

[0071] In a plant factory with sunlight as the main light source, the artificial light source provided in the tomato seedling stage is 90% red light and 10% blue light according to the light quality spectrum integral percentage;

[0072] The red light is red light R with a peak wavelength of 615-650nm, and the blue light is blue light B with a peak wavelength of 430-470nm.

Embodiment 2

[0074] This embodiment provides a method for promoting the growth of tomato seedlings. The method for promoting the growth of tomato seedlings includes providing artificial light sources to growing tomatoes to promote the growth of tomato seedlings, specifically:

[0075] In plant factories with artificial light sources as the main light source, the artificial light source provided by the tomato seedling stage is 75% red light, 15% blue light and 10% continuous spectrum of full visible light according to the integral percentage of light quality spectrum;

[0076] In a plant factory with sunlight as the main light source, the artificial light source provided in the tomato seedling stage includes 80% red light and 20% blue light according to the integral percentage of light quality spectrum;

[0077] The red light is red light R with a peak wavelength of 615-650nm, and the blue light is blue light B with a peak wavelength of 430-470nm.

Embodiment 3

[0079] This embodiment provides a method for promoting the growth of tomato seedlings. The method for promoting the growth of tomato seedlings includes providing artificial light sources to growing tomatoes to promote the growth of tomato seedlings, specifically:

[0080] In plant factories with artificial light sources as the main light source, the artificial light source provided by the tomato seedling stage is 75% of the red light, 20% of the blue light and 5% of the continuous spectrum of the full visible light according to the integral percentage of the light quality spectrum;

[0081] In a plant factory with sunlight as the main light source, the artificial light source provided in the tomato seedling stage includes 85% red light and 15% blue light according to the light quality spectrum integral percentage;

[0082] The red light is red light R with a peak wavelength of 615-650nm, and the blue light is blue light B with a peak wavelength of 430-470nm.

Abstract

The invention relates to a light source distribution method and light source parameters for promoting growth of tomato seedlings in winter or lack of light. An application of the method for promotingthe growth of the tomato seedlings in a plant factory includes the aspect of providing artificial light sources for the tomato seedlings during growth to promote the growth of the tomato seedlings. The method has the following beneficial effects: according to the application of the method for promoting the growth of the tomato seedlings in the plant factory, corresponding spectrums suitable for the growth stage are supplemented in the growth process of the tomato seedlings to provide the plant with the most suitable light supplement solution, the method covers the vegetative growth period of solanum lycopersicum from seeding to flower bud appearance, improves the absorption rate and utilization rate of the solanum lycopersicum to light energy, promotes the conversion of electrical energy into biochemical energy of the solanum lycopersicum, ensures the strong seedling rate of the tomato seedlings in winter or lack of light, promotes precocious flowering and improves quality of the seedlings.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a method for promoting the growth of tomato seedlings and its application in plant factories, in particular to a light source distribution method and light source parameters for promoting the growth of tomato seedlings in winter or in a light-deficient environment. Background technique [0002] Light is closely related to the growth of crops. Capturing light energy to the greatest extent and giving full play to the potential of plant photosynthesis will be directly related to the benefits of agricultural production. In recent years, in order to meet market demand, greenhouses are widely used to produce off-season flowers, fruits, vegetables, etc. Due to the short sunshine time in winter and spring, slow growth of crops and low yield, it is urgent to supplement light. [0003] According to the natural law of plant growth and the principle that plants use sunlight for phot...
