What is the significance of light inside the greenhouse?
What we need to know is that the growth rate of plants is determined and light intensity, that is, the amount of light radiation energy absorbing light radiation energy on the surface of the plant does not depend on the number of light sources. Many people ask, what is the significance, how to do the interior lighting of the greenhouse, and what kind of light source should be used?
The significance of inside the greenhouse is to extend enough light intensity within a day. It is mainly used for planting vegetables in late autumn and winter, roses and even chrysanthemum seedlings. Greenhouse lighting has a huge impact on growth and seedlings. Usually, the tomatoes will start light after the plant seedlings grow two leaf leaves. Continuous light can reduce the seedling preparation period of 6-8 days. But more than 24 hours of light will be disorders of plant growth. The most suitable light time is 8 hours a day. In the days of cloudy and low light intensity, artificial lighting is necessary. At least at least 8 hours of light per day, and the time of light is fixed every day. However, the lack of night break can also cause plant growth disorders and reduce production.
For tomatoes, the most effective light time is from dusk to midnight, 16: 00-24: 00 or from midnight to 24: 00-8: 00. In practice, we should provide light from plants throughout the growth period, that is, from seedlings to planting. In the last period, we should reduce light until 6 hours or even stop for 2-3 days a day. If due to poor light conditions, it takes a long time when the planting period is required, and the light will usually last for one month.
Optional selection
When using artificial light sources, we must choose natural light closest to meet the conditions of plant photosynthesis. The light source should have the following characteristics:
1. Highly -efficiently convert electricity into radiation energy
2. A high radiation intensity in the effective range of photosynthesis, especially low infrared radiation (thermal radiation)
3. The radiation spectrum of light bulbs meets the physiological requirements of plants, especially in the effective spectrum area of ​​photosynthesis.
The comparative intensity is in an effective area of ​​photosynthesis. Among the various artificial light sources of horizontal radiation, the energy conversion effect of sodium lamps is twice as high as the mercury lamp. Sodium lamps are the most effective light sources that affect the photosynthesis of the plant in the greenhouse. The tubular sodium lamp can reach 150lm/W high -light radiation, which is currently the most favorable choice for the growth of various crops. Increasing the sodium steam pressure in ceramic arc light can expand the spectrum of blue and red light, which is the high range of wavelengths pursuing. Their difference is to increase the range of 0-40%of the blue light and activate the chlorophyll of the plant.
