What to pay attention to when filling light in greenhouses:
1. Supplement light in summer:
In summer, cloudy days are very harmful to the main stem and must be filled with light. If you encounter the sky's eye and the light lasts for a long time, then there is no need to fill the light.
2. The way of supplementing light when the winter day is a sunny day:
In order to better heat the vegetables in the greenhouse in winter, they are usually scraped at nine o’clock and covered again at three o’clock in the afternoon. In that way, it’s not enough for more than seven hours of sunlight to be irradiated in a day. In the basic of daylight illumination, supplement the necessary light for plants.
3. When there is no sun on a cloudy day and the sky is too bright, it must be filled with light:
The sun's light is a very weak light source directly coming back through the clouds, and the light necessary for photosynthesis of plants and plants cannot be considered from a distance. Therefore, in this type of continuous cloudy, haze, rainy and snowy weather, it is necessary to take immediate measures to supplement the light during the day. .
4. The effect of choosing environmentally friendly plant growth lights when supplementing light is remarkable
The chromaticity of the light is what everyone feels as a small animal, and the light that everyone feels has little effect on the growth and development of plants. The special type of light for plant growth lights, although everyone feels that it is not bright, it is more plant growth. Development must attract light, so the actual effect is significant.
5. It is unreasonable to use ordinary light bulbs as special tools for plant light supplement
As lighting, fluorescent lamps are indeed reasonable for plants, but the actual effect is very small, because there is too little effective light in the light it sends.
