In northern China, the emergence of wheat has eased local food shortages and has even become one of the important staple foods in the region. But in the process of planting wheat, nitrogen and wheat yield and quality is closely linked to the lack of nitrogen will lead to a sharp sharp drop in wheat production, and we can judge by the chlorophyll content of nitrogen in wheat growth process of a lack of status, It can then guide farmers to use nitrogen fertilizers. Some people may ask how to get the value of chlorophyll content? This requires the application of professional chlorophyll content meters.
Chlorophyll content meter, as the name implies, is a plant physiological instrument for determining the relative amount of chlorophyll. In plant chlorophyll research work, we found that nitrogen is an important component of chlorophyll. It has a close correlation with chlorophyll content and plant growth status. When plants lack nitrogen, the amount of chlorophyll will be reduced, and leaf color will be reduced. Light greenish yellow, decreased photosynthesis, decreased photosynthetic products. When the supply of nitrogen is sufficient, the vegetative and leaf area of ​​the crop increases, the chlorophyll content is relatively high, the leaf color is dark green, and the photosynthesis is vigorous. This has positive effects on improving the yield of crops and further improving the quality of the products. Role. Therefore, knowing the relative content of chlorophyll in plants, we can determine whether plants are deficient in nitrogen, and in the process of wheat cultivation, we can achieve the purpose of precise fertilization, which can increase wheat yield and quality.
Therefore, in northern China, many wheat growing areas use the chlorophyll content meter as an important auxiliary tool for wheat cultivation. By measuring the chlorophyll content of the plant through the chlorophyll content meter, farmers can reasonably apply nitrogen fertilizer, increase the utilization rate of nitrogen fertilizer, and increase wheat yield. quality. According to the current results of the application of some wheat fields, it was found that the chlorophyll content meter can also help reduce the nitrogen fertilizer use by 10% under the premise of ensuring that the crop yield does not decrease. This will not only increase the yield of crops but also reduce the amount of crops for growers. The production cost is a very good thing.
LED Car Light
LED car lights refer to the use of LED technology inside and outside the car for external and internal lighting. External lighting equipment involves thermal limits and EMC issues, as well as many complex standards for unloading load testing. LED car lights can be widely used to create the environment in the car. The life span is 50,000 hours. The structure of the LED is sturdy and not easily affected by vibration. The light output brightness will not significantly decrease during use. LED car lights are suitable for various lighting applications of automotive electronics, including headlights (high beam and low beam), fog lights, tail lights, brake lights, turn signal lights, daytime running lights, pedal lights, instrument lights, license plates Lights, door lights, interior lights, width indicator lights, navigation, entertainment systems, backlights and indicator lights, etc.
- Advantage
1. Energy saving: Light-emitting diodes are directly converted from electrical energy to light energy. Compared with ordinary car bulbs, the power consumption is only 1/10 of that of traditional lamps, which can better save fuel consumption and protect car circuits from being burned by excessive load currents. Bad.
2. Environmental protection: There are no ultraviolet and infrared rays in the spectrum, low heat generation, no radiation, low glare, and the waste can be recycled, no pollution, no mercury, and safe touch. It is a typical green lighting light LED source.
3. Long lifespan: There is no loose part in the lamp body, and there are no shortcomings such as easy burning, thermal deposition and light decay of the filament. Under the appropriate current and voltage, the service life can reach 80,000 to 100,000 hours, which is longer than that of traditional light sources. More than 10 times longer. (It has the characteristics of one-time replacement and lifetime use)
4. High brightness and high temperature resistance. (Electric energy is directly converted into light energy, and the heat is small, and it can be touched by hand, which is safe and secure)
5. Small size. The designer can change the lamp mode at will to make the car diversified. Automobile manufacturers' favor of LEDs is entirely determined by the advantages of LEDs themselves.
6. Good stability, strong anti-vibration performance of LED: resin encapsulation, not easy to break, easy to store and transport.
Seven, the luminous purity is high, the color is clear and bright, no lampshade is needed to filter the light, and the light wave error is within 10 nanometers.
8. The response speed is fast, no hot start time is needed, and it can emit light within microseconds. The traditional glass bulb bulb has a 0.3 second delay, which can prevent rear-end collision and ensure driving safety.
