The plant lamp was developed by Nanjing Agricultural University. It is the transformation of the research results of scientific research projects such as the National 863 Program, the National Natural Science Foundation of China, the National Science and Technology Support Program, and the Science and Technology Support Program of Jiangsu Province. It is an ideal lighting device for facility agriculture. After more than ten years of application testing and continuous improvement, the technology and products are mature and can be used with confidence.

1. Technical features:

1. According to the principle of plant photobiology, based on the characteristics of light demand of plants, the suitable spectral energy distribution parameters are matched with suitable suitable photoelectric control parameters to more efficiently meet the needs of plant growth and have high light efficiency.

2. The light distribution is reasonable and uniform, which meets the requirements of plant groups for light.

3. The shape is optimized, the structure is compact, and the space occupation is small, which is convenient for the placement of various space sizes.

4. Slow light decay and stable light output.

5. High power density and strong light output.

6. There are no moving parts as a whole, high reliability and stability, and long life of the whole lamp.

7. Better protection, waterproof and dustproof, and higher environmental adaptability.



2. Function

1. The spectral distribution is reasonable, and it has a plant growth effect equivalent to sunlight.

2. High optical density output, which can meet the strong demand for high optical density in the whole growth period of light-loving crops (such as tomato, rice, watermelon seedlings, etc.).

3. Can effectively inhibit plant growth. In the seedling stage, it can effectively increase the stem diameter of seedlings, shorten the internodes and plant height, and inhibit leggy growth.

4. It can effectively improve the photosynthetic efficiency of plants, enhance the nutrient accumulation of plants, promote the healthy growth of plants, effectively resist the invasion of diseases, and improve the ability of plants to resist diseases.

5. The output spectrum can kill pathogenic bacteria in the air and on leaves, and inhibit diseases.

6. In a low-temperature and high-humidity environment, the output spectral energy is conducive to eliminating water droplets on the leaf surface and increasing the temperature of the mesophyll, eliminating the hidden danger of bacteria entering the leaves through the stomata.

7. It can effectively control the seedling cycle, and delay or shorten the seedling growth time according to market demand or changes in agricultural time.



3. How to use:

It can be installed arbitrarily according to the planting conditions and space conditions.

1. It can be installed horizontally, and the light is projected from the horizontal direction;

2. It can be installed or hoisted vertically, and the light is projected vertically downward or vertically upward;

3. It can be installed at any angle, and the light can be projected at any angle.

4. In use, water should not be sprayed directly to the lamp body, especially the luminous body.

5. On sunny days, it is recommended to shorten the turn-on time. The turn-on time can be adjusted to 9:00-11:00 am and 3:00-6:00 pm.

6. On cloudy and rainy days, it is recommended to turn on the lights at 9:00-17:00.

7. The lighting time should be reasonably determined according to the photoperiod requirements of different plants and different growth periods.

8. For seedling raising, if it is necessary to delay the time of seedling formation, the daily light time can be appropriately shortened and the optical density can be reduced; if the seedlings need to be formed in advance, the daily light time can be appropriately increased and the optical density can be increased.



4. Installation distance

1. For seedling raising, the vertical distance between the lamp and the leaf canopy of the seedling cannot be less than 1-1.2 meters, and the distance between the lamps is 3X3 meters.

If you encounter rainy and little sunshine for more than 3 consecutive days, it is recommended to increase the installation density of the lights, use a square combination or a diamond combination, and the center distance between the lights should not be higher than 2 meters.

2. It is used for raising seedlings. In sunny days, the distance between the lamps can be increased according to the specific conditions.

3. Light for vegetative growth or reproductive growth. The installation distance should be reasonably determined according to the plant's preference for light.

5. Through the application of plant fill light, the low temperature, rain and fog, and lack of light in winter seedlings are troubled, and there is no need to worry about the failure of seedlings. There is no need to be afraid of rain for 7-10 consecutive days, and normal good seedlings can still be bred with fill light. It has a good defense effect on anthracnose and brown rot caused by low temperature, high humidity and lack of light.

6. The only thing that is difficult to promote is: high one-time investment cost and high operating cost. For large-scale use, the capacity of the transformer and the carrying capacity of the line must be considered at the beginning, otherwise it will cause potential safety hazards.
