In today's rapidly developing facility agriculture and plant factories, light, as a core environmental factor affecting plant photosynthesis, morphogenesis, and metabolic products, has become the key to improving crop yield and quality through precise regulation. The comprehensive testing system for plant illumination, light, color, and electricity, with its multi parameter integrated monitoring and spectral analysis capabilities, provides a scientific basis for optimizing the light environment for plant growth and is becoming a popular tool in modern agriculture“Optical technology weapon”.

1、 Technical core: Full spectrum coverage and multi parameter analysis

The system is designed to350-800nmFull spectrum monitoring as the core, covering ultraviolet light（350-399nm）Blue light（400-499nm）Green light（500-599nm）Red light（600-700nm）And near-infrared light（701-780nm）Band, capable of simultaneously collecting chlorophyll weighted and photosynthetic photon flux density（PPFD）Color temperature, color rendering index, etc18Key parameters. For example, in tomato cultivation, the system monitors red light by（660nm）Compared to far red light（730nm）Proportion can accurately regulate plant stem elongation and fruit coloring; And by analyzing the ratio of blue light to red light（B:R）It can effectively induce lettuce leaf thickening and improve nutritional quality.

2、 Core application scenario: closed-loop optimization from research and development to production

1. Research and Quality Control of Plant Lights

InLEDIn the production of plant lamps, the system can detect the spectral distribution of the lamps in real timePPFDUniformity and luminous efficiency parameters. For example, a company discovers through the system that it produces6500KFull spectrum lamp450nmBlue light band exists15%Adjust the ratio of fluorescent powder in a timely manner to increase the photosynthetic radiation power of the lamp output deviation12%Significantly increased the growth rate of lettuce seedlings.

2. Facility agriculture light environment regulation

In greenhouse cultivation, the system monitors the light intensity distribution of the crown layer in real time through multiple spectral probes, and automatically adjusts the brightness of the supplementary light based on the plant light response curve. For example, in strawberry cultivation, the system dynamically adjusts the ratio of red and blue light according to the light requirements of different growth stages (vegetative growth stage, flowering stage, fruiting stage), resulting in an increase in individual plant yield25%At the same time, the rate of malformed fruits will be reduced18%drop to5%.

3. Standardized production in plant factories

In a vertical farm, the system is linked with the environmental control system to build“light-Wen-wet-qi”Collaborative regulation model. For example, a plant factory discovered through the system that25℃In the environment, whenPPFDfrom200μmol/m²/supgrade to400μmol/m²/sWhen the dry matter accumulation of lettuce increases30%But whenPPFDexceed600μmol/m²/sAt that time, the leaves showed a phenomenon of light suppression. Based on this data, the factory optimized the shelf spacing and fill light strategy to improve space utilization40%.

3、 Technology Extension: From Basic Research to Industrial Empowerment

This system not only serves the production end, but also becomes an important tool for plant photobiology research. Research institutions have utilized their high-precision spectral analysis capabilities to reveal the regulatory mechanisms of light quality on plant secondary metabolites such as anthocyanins and flavonoids; By accumulating long-term monitoring data, the system can construct a plant light demand model, providing a light environment adaptation plan for the breeding of new varieties.

The comprehensive testing system for plant illumination, light, color, and electricity quantifies the parameters of the light environment, achieving the growth of plants from“Experience driven”to“data-driven”The leap. With the Internet of Things andAIThe integration of technology will further develop the system towards intelligence and portability in the future, contributing to the development of global agriculture“Light Efficiency Revolution”Inject new kinetic energy.
