Laser plant growth technology uses laser light of specific wavelengths to irradiate plants to promote their growth and development and increase crop yields. This technology is increasingly favored by the agricultural sector due to its efficiency and precision. However, when using laser equipment, operators must take appropriate safety measures, especially eye protection.
1. Application of laser in agricultural field
A. Laser weeding: Use the high energy and concentration of laser to precisely irradiate weeds in farmland, thereby killing weeds without harming crops.
B. Laser breeding: irradiating crop seeds with laser light changes the genetic characteristics of the seeds and breeds better varieties. In addition, laser irradiation can also accelerate seed germination, increase seed germination rate, promote crop growth, make crops mature earlier, resist diseases, and increase yields.

C. Laser measurement: Use the high precision and speed of laser to quickly and accurately measure farmland, such as measuring land area, slope, etc.
D. Laser soil analysis: Use laser spectral analysis technology to analyze the components in the soil to help farmers better understand the fertility and moisture conditions of the soil.
E. Laser plant protection: The sterilization and insect-proof effects of laser can be used to protect crops and prevent the occurrence of diseases and insect pests. Since laser is a monochromatic light, it has a repelling effect on all migrating insects.
2. Principle of laser plant growth
The principle of laser plant growth is to use laser synthetic spectrum technology to replace sunlight to allow plants to perform photosynthesis, extending the light required for photosynthesis of crop plants. Laser plant growth lights are usually composed of 430nm, 450nm, 480nm, 630nm, 650nm, 660nm, 730nm, 780nm and other wavelength bands required for plant photosynthesis.
The wavelength of laser has an important influence on its application effect. Lasers of different wavelengths have different effects on plants. For example, some specific wavelengths of laser light can promote plant growth and development, while other wavelengths of laser light may have a negative impact on plants. Therefore, when selecting laser equipment, it is necessary to select the appropriate laser wavelength based on specific application requirements.
Laser protection is a series of measures taken to prevent laser equipment from causing damage to personnel and equipment. Here are some ways to protect yourself from lasers:
① Set up eye-catching signboards: Set up eye-catching signboards on laser equipment with warning text, such as "Laser is dangerous, please do not approach".
② Closed optical path system: Use a sealing sleeve of corresponding material to seal the internal optical path system of the laser equipment to avoid direct exposure.
③ Use objects that can shield optical fibers: For workbenches using laser equipment, glass or other objects that can shield optical fibers should be used as much as possible.
④ Wear protective clothing and laser protective glasses: For laser systems that cannot be completely enclosed, users should wear work clothes and laser protective glasses that can shield the absorbed light. When choosing laser protective glasses, make sure that the glasses can cover the possible exposure during operation. All laser wavelengths. For red and blue lasers commonly used in agricultural applications, protective glasses should cover at least the wavelength range of 400nm -800nm.
Optical density is a measure of the protective ability of protective glasses, indicating the proportion of harmful light that the glasses can reduce. For laser equipment in agricultural applications, it is recommended to choose protective glasses with an optical density of at least 6 to ensure adequate protection.
⑤ Set up protective fences and isolation facilities: The site where laser equipment is used should be equipped with protective fences and isolation facilities to prevent non-staff from entering by mistake.
⑥ Do a good job of inspection: Before and after using the laser equipment, you should do a good job of inspection of the laser equipment to avoid lighting failures in the laser equipment.
In general, through the reasonable selection and use of laser protective glasses, you can enjoy the agricultural revolution brought by laser technology while ensuring that the eye safety of every participant is properly protected. Choosing appropriate laser protective glasses is a key step to protect the eye safety of operators, and is also an important guarantee for achieving efficient agricultural production.
