The correct use of LED plant lights in Shenzhen, China will bring good results to greenhouse planting
Most parts of the north are located in a temperate monsoon climate. In winter and spring, affected by the southward movement of cold air from Siberia, rain and snow sometimes form due to the convergence of cold and warm air. 1-3 days with low temperature and little light, 7-8 days or even cloudy days with little light. Due to the promotion of the demand for LED plant lights in foreign trade in the market, greenhouse planting began to appear in large numbers, but only to solve the problem of planting environment. However, there is still insufficient sunshine. When the light intensity is lower than its compensation point, the organic matter consumption is greater than the accumulation, and the dry weight of the plant decreases. The growth of the plant is also weak. So it is necessary to use LED plant lights to fill light.
With the emergence of LED plant growth lights, the development of indoor planting is now faster and faster. Now indoor growers will choose to use the Guangdong LED plant light factory LED full-spectrum plant light to supplement light. LED plant lights are also widely used in greenhouses to grow plants with high yield and fast harvest. How to use LED plant lights to achieve this goal. But how to make the planting effect better, this is a problem that people are more concerned about.
1. Illumination distance
The illumination distance of 1000LED plant lights is very important. You need to adjust the points for different plants at different stages, and also unify the distance, so that the uniformity of the light will be strengthened. If the distance is not well controlled, it may damage the plants. Grow. The general recommendation is that the germination stage distance: 60 cm, the seedling stage distance: 75 cm, the growth stage distance: 45 cm, and the flowering stage distance: 30 cm.
2. Evenly distributed installation
Measure the floor area. Multiply the length by the width to get the square meters of the planting area. You can make the right choice based on how much power to provide per square meter, that is, how many LED plant lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, and the light will be more uniform, which has a very good effect on the growth of plants.
3. Heat dissipation issues
If you don’t pay attention to the air circulation, the temperature of the space will always increase. The heat dissipation of the LED plant light will be a problem, which will affect the performance and life span. Therefore, you can choose air conditioning, fan heat dissipation or keep the air circulating, etc. Method.
4. Fill light distance
LED plant lights will generate a certain amount of heat. If they get too close, they will burn the plants and cause some damage to the plants. If the distance between the LED full-spectrum plant light and the plant is too far, it will greatly reduce the light utilization rate, thereby weakening the effect of supplementary light. If the LED plant supplement light generates less heat than other plant lights, it will generate a certain amount of heat. If the distance is too far, it will also affect the effect of fill light.
5. Fill light time
If the weather is fine, the plants can fill up the light for 2-3 hours in the morning and evening when the light is weak. If it is cloudy, rainy or hazy, plants can fill up the light all day. Plants have a time limit for supplementing light. Plants have 14 hours of supplementary light a day, which is a very suitable time. They also need to rest at night and have time to breathe.
Installation method and method of LED plant light
1. A mounting bracket
1. Installation of the triangle bracket: Take out the triangle bracket from the packing box, open the support feet of the bracket, and extend the support rod to complete the installation.
2. Install the LED plant light: Fix the screw under the LED plant light on the top of the bracket, rotate the tripod support rod, tighten the fixed parts, and the installation is complete.
Two, B mounting bracket
1. Mounting bracket: Take out the mounting bracket and mounting accessories from the packing box, insert the round iron piece from the bottom of the steel pipe (higher than the round hole under the steel pipe), insert the pin into the round hole under the steel pipe, and fix the round iron piece , And finally rotate the mounting bracket into the soil as a whole (the round iron sheet should be close to the ground or buried in the soil).
2. Install LED plant lights.
Remove the screw on the plant growth lamp, fix the top end of the LED plant supplement light to the upper end of the horizontal bracket, turn the screw, tighten the fixing piece, and complete the installation.
Three, C mounting bracket
1. Mounting bracket: Take out the mounting bracket from the packing box, connect the two long steel pipes together and rotate and tighten, insert the horizontal bracket from the top of the connected steel pipe, adjust the height according to the height of the plant and tighten it, from the bottom of the connected steel pipe (high Insert the round iron piece into the round hole under the steel pipe, insert the pin into the round hole under the steel pipe, fix the round iron piece, and finally rotate the mounting bracket into the soil (the round iron piece should be close to the ground or buried in the soil) ).
2. Install the LED plant growth light: remove the screw on the plant growth light, fix the top of the LED plant growth light to the upper end of the horizontal bracket, turn the screw, tighten the fixing piece, and complete the installation.
3. Power access mode.
Connection method 1: Insert the power cord connector into the power port of the growth lamp (pay attention to the connection of the interface bayonet when inserting), tighten the nut on the power cord, and plug the other end of the power socket directly into the AC220 power socket.
Connection method 2: Insert the power cord connector into the power port of the LED plant light and tighten it. The red wire at the other end of the power supply is the live wire; the blue wire: the neutral wire; the yellow wire: the ground wire is connected to the AC220 power supply. When the power is turned on, the LED plant light works normally.
Therefore, when installing LED plant lights, the lighting distance of the ball should not be too far or too close. At the same time, the installation of LED plant lights should be arranged reasonably according to the size of the space. Correct installation is a prerequisite for good results.
Tips for growing LED plant lights in greenhouses:
(1) Different types of plants should be planted reasonably and arranged according to natural rules, such as: planting plants in the northern hemisphere, according to the principle of high north and low south, so that all plants can be evenly illuminated, and try not to shade between plants. ；
(2) At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of LED plant lights. Use reflective materials when setting up the frame. In addition, the brackets do not need to be all 90 degrees upright. Keep the middle brackets upright, north and south. The brackets on both sides are slightly tilted, which can increase the light utilization rate by 5--10% and be reused by plants.
(3) The roof of greenhouses is cleaned and the “roof garbage” is cleaned regularly. Otherwise, the transparency is not enough, which will have a great impact on the light and temperature in the shed, which will affect the photosynthesis and respiration of plants, and ultimately affect the yield and quality of plants. .
(4) Using LED plant lights to fill light, on the one hand, the light distance can be appropriately shortened. Generally, when buying LED plant lights, it will be based on the installed area, and the irradiated area of LED plant lights can be combined to purchase, and the irradiated area can be appropriately shortened and increased within a reasonable range. Plants fill light.
(5) Reflective film
The mulching film and the reflection of the water droplets attached to the surface under the mulching film can strengthen the reflected light and scattered light near the ground, and the mulching film still has a better thermal insulation effect.
These make LED plant lights more popular in the market, and are deeply loved by greenhouse growers, industrial growers and plant research and planting units. LED plant lights are wholesaled in large quantities, and the future development trend of LED plant lights will get better and better.
