Winter is the most important period for the production of vegetable greenhouses. However, because of the low temperature in winter and the frequent occurrence of natural disasters such as ice, snow, and frost, it will adversely affect crops in vegetable greenhouses. Therefore, in the cold winter, how to use warmth, heat preservation and supplement light is an important skill to ensure the quality and efficiency of vegetable greenhouse production. So the greenhouse supplement light is very important
Suggestions for supplement light in greenhouses at night
Artificial light sources can be used to compensate during periods of lack of illumination. It is recommended to use light waves in the field of horticultural production at 400-460 nm and 600-660 nm, as this range of light is necessary for photosynthesis.
The growth of melon and solanaceous vegetables requires a minimum temperature of 13 °C or above, and stop growing when the temperature below 10 °C.
Generally, vegetables should be kept warm at night to avoid freezing, so that plants can grow at night, but basically, do not grow when the temperature below 10 ° C, so the greenhouse temperature is controlled above 10 ° C.
What is supplement light in Greenhouse
What we know is that the growth rate of plants depends on the intensity of light, that is, the amount of radiant energy absorbed by plants. It does not depend on the number of light sources.
What is the meaning of greenhouse interior lighting, how to do it, what kind of light source should I use?
The meaning of interior lighting in a greenhouse is to extend enough light intensity throughout the day.
It is mainly used to grow vegetables, roses and even chrysanthemum seedlings in late autumn and winter.
Greenhouse lighting has a huge impact on growth and seedling quality.
Artificial lighting is necessary in days of cloudy and low light intensity. The crop is given 8 hours of light per day at least at night, and the time of daylight is fixed.
However, reducing the night rest time can also lead to plant growth disorders and reduced production.
How to supplement light in Greenhouse?
Many friends say that the role of the supplement light is not very good. In fact, a large part of it is wrong with the use of lights.
The supplement light is not open indoors for 10 hours or outdoor nights for a few hours or 24 hours.
The correct method of application is based on the moment of illumination of the crop.
The supplement light in the greenhouse is 12-14 hours in the flowering period, and the sunshine in the winter is 5-7 hours. We pass the LED plant growth light to compensate for the missing light to increase crop yield. It also can reduce disease.
Plants supplement light at night is composed of three stages, the supplement light stage, the absorption stage and the black period.
