A glass greenhouse can create a suitable environment for crops to grow in, and the greenhouse can meet various conditions required for crop growth, such as temperature, humidity, etc. Today, the editor will take you to briefly understand the relevant content of what to pay attention to when adding light in a glass greenhouse.
1. Summer supplementary lighting:
Summer overcast weather has a significant impact on plants, and it is necessary to supplement light. If it's sunny and the light lasts for a long time, there's no need to fill in the light.
2. When it's sunny during the day in winter, the method of supplementing light is:
In order to keep warm in winter vegetable greenhouses, the straw covers are usually lifted at 9 o'clock and re covered around 3 o'clock in the afternoon. This way, the sunlight only lasts for more than seven hours at the end of the day, which is far from enough. Therefore, it is necessary to supplement the light needed by plants on the basis of sunlight.
3. When there is no sun on a cloudy day and the sky is very bright, supplementary light is also needed:
The faint light emitted by the sun through the clouds is far from sufficient for plant photosynthesis. Therefore, in cloudy, foggy, rainy and snowy days, it is necessary to supplement the light in a timely manner.
4. The use of energy-saving plant growth lights for supplementary lighting has a significant effect
The brightness of light is what we perceive as animals, and the light we perceive has almost no effect on the growth of plants. Although we cannot feel brightness, it is the light that plants need to attract, so the effect is very obvious.
5. It is unscientific to use ordinary light bulbs as a plant light supplement tool
As lighting, incandescent lamps are effective for plants, but the effect is minimal because they emit too little useful light.
Through the introduction of the editor, we hope that users can pay attention to the importance of supplementing light for crops in glass greenhouses, so that crops can have a good growth environment and grow normally.
