2. The Basic Principles and Influencing Factors of Plant Growth
2.1 The Basic Process of Plant Growth
2.1.1 Photosynthesis
Photosynthesis is a crucial metabolic process in which plants utilize light energy to convert carbon dioxide and water into glucose and oxygen. It serves as one of the key links in plant growth and is also an important way to maintain the ecological balance of the Earth. During photosynthesis, plants use chlorophyll to absorb light energy, convert it into chemical energy, and release oxygen into the air.
Photosynthesis has a significant impact on plant growth and development. Factors such as light intensity, light quality, and photoperiod can affect the efficiency of photosynthesis and plant growth rate. In recent years, LED lighting has been widely used as a new type of light source for plant growth illumination. LED lighting boasts adjustable wavelengths, low energy consumption, and a long lifespan, providing suitable lighting conditions for plants to enhance photosynthesis efficiency, increase plant growth rate, and improve yield.
Studies have shown that under appropriate LED lighting, plants exhibit increased chlorophyll content, improved photosynthesis rate, shortened growth period, and vigorous growth. Therefore, the rational utilization of LED lighting's impact on plant growth can regulate plant growth and development, increase crop yield, and promote healthy plant growth.
In conclusion, the importance of photosynthesis in plant growth cannot be overstated. By studying the effects of LED lighting on plant growth, we can gain a better understanding of plant growth mechanisms, optimize plant growth conditions, promote healthy plant growth, and provide humans with more green and healthy plant products.
2.2 Factors affecting plant growth
2.2.1 The impact of lighting conditions on plant growth
Light conditions are one of the important factors affecting plant growth, and light intensity and light quality have a direct impact on plant growth [3]. Insufficient light intensity can lead to insufficient synthesis of chlorophyll in plants, affecting photosynthesis and growth and development. Excessive light intensity can cause excessive accumulation of photosynthetic products, affecting the normal function of plants. Different wavelengths of light also have different effects on plant growth. Red and blue light are the two main light qualities required for plant growth. Red light promotes photosynthesis in plants, while blue light promotes plant growth and development.
Research has found that LED lights, as an ideal lighting source for plant growth, can provide suitable light conditions to meet the needs of plants at different growth stages. By adjusting the light intensity and quality of LED lights, precise control of plant growth can be achieved, promoting plant growth, improving yield and quality [4].
Future research directions will focus more on exploring the specific impact mechanism of light conditions on plant growth, further optimizing the ratio and control methods of LED lights to better meet the growth needs of different plants. As a green and energy-saving light source, LED lights have broad application prospects in modern agriculture and will bring new breakthroughs to future agricultural production.
By studying the impact of light conditions on plant growth, we can not only promote the progress of plant growth technology, improve crop yield and quality, but also explore the mysteries of plant growth, providing theoretical support for humans to better utilize plant resources.
3. The Application of LED Lighting in Plant Growth
3.1 The Principle of LED Lighting
LED lighting, as a new type of illumination method, has been widely applied in the agricultural field in recent years. This study aims to explore the effects of LED lighting on plant growth, particularly in terms of plant growth rate, plant health, and yield [5]. The results indicate that the different wavelengths and light intensities of LED lighting have significant impacts on plant growth [6]. Among them, blue and red wavelengths of LED lighting demonstrate a promoting effect on plant growth, enhancing the growth rate and health status of plants. However, excessively high or low light intensities can have negative impacts on plant growth, resulting in poor or slow growth. The application of LED lighting also produces different effects on plants at different growth stages, requiring targeted selection of LED lighting wavelengths and intensities for different plant species [7]. Therefore, the rational utilization of LED lighting in agricultural production can effectively improve plant growth rate and yield, bringing new development opportunities to agricultural production.
3.2 The mechanism of action of LED lighting in plant growth involves several key factors
The mechanism of LED lighting in promoting plant growth lies in photosynthesis. Photosynthesis is the process where plants utilize light energy to convert carbon dioxide and water into energy. LED lighting provides the specific wavelengths of light energy required by plants, thus enhancing photosynthesis. Additionally, LED lighting can regulate the synthesis and transportation of plant growth hormones such as gibberellins and auxins, further influencing plant growth and development.
However, the impact of LED lighting on plant growth is also influenced by several factors. The light intensity and duration of LED lighting play crucial roles in plant growth, and different plants have varying demands for light. The wavelength of LED lighting also affects plant growth, as different wavelengths have varying impacts on plant growth and flowering [8]. Other factors like the distance and angle of LED lighting also influence the absorption and utilization efficiency of light energy by plants.
Therefore, it is essential to select appropriate parameters such as light intensity, wavelength, and irradiation distance of LED lighting based on different plant species and growth stages to achieve the best effect in promoting plant growth. In the future, with the continuous development and improvement of LED lighting technology, its application in plant growth will become increasingly widespread, bringing more opportunities and challenges to agricultural production.

Existing studies have shown that LED lighting has a significant impact on plant growth. LED lights with different wavelengths can promote or inhibit plant growth and development. For instance, red light typically stimulates photosynthesis and growth, while blue light affects plant morphology and physiology. Additionally, plants vary in their response to different wavelengths, with some being more sensitive to red light and others to blue light [9].
The light quality and intensity of LED lighting also have an effect on plant growth. Appropriate light quality and intensity can enhance photosynthetic efficiency, promoting plant growth and development. However, excessively high or low light intensities can inhibit photosynthesis, affecting plant growth.
Notably, LED lighting, as a green and environmentally friendly light source, has gradually gained widespread application in the field of plant growth. By properly configuring the spectrum and light intensity of LED lighting, the growth rhythm and quality of plants can be effectively controlled. Therefore, research on the impact of LED lighting on plant growth not only helps improve the efficiency and yield of plant growth, but also contributes to energy conservation and reduces light pollution. In the future, the application prospects of LED lighting in the field of plant growth will be even broader.

Wherein, Pmax represents the maximum photosynthetic rate of the plant under light saturation, I represents the light intensity, and P represents the plant's ability to respond to light. With this model, we can quantitatively analyze the impact of different lighting conditions on plant growth and draw conclusions.
Through this study, we have deeply explored the impact of LED lighting on plant growth and provided valuable insights for research on plant growth under various lighting conditions.
