Winter is the most important period for the production of vegetable greenhouses. It is the most obvious effect on the yield of vegetable greenhouses in winter. It is because the winter temperature is low, and there are natural disasters such as ice, snow and frost. The crops inside have adverse effects, so in the cold winter, how to use warming, heat preservation and light filling is an important skill to ensure the quality and efficiency of vegetable greenhouse production.
Requirements for light temperature at night in the greenhouse
Night fill light requirements for lighting:
Artificial light sources can be used to compensate during periods of lack of illumination. It is recommended to use lightwave lengths of 400-460 nm and 600-660 nm in the field of horticultural production because the light in this interval is necessary for photosynthesis.
Night light fill temperature requirements:
Melons and solanaceous vegetables require a minimum temperature of 13 degrees Celsius or above. If the growth is stopped below 10 °C, the vegetables should be kept warm at night and not damaged by freezing, so that the plants can grow at night, but basically do not grow below 10 °C, so the greenhouse greenhouse temperature at 10 °C cannot. Growed up.
What we need to 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. Many people ask, what is the meaning of greenhouse interior lighting, what to do, which light source should be used? The meaning of greenhouse interior lighting is to extend enough light intensity in one day. It is mainly used to cultivate 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 daylighting is fixed. However, the short nighttime rest time can also lead to plant growth disorders and reduced production.
Many friends say that the role of the fill light is not good. In fact, a large part of it is wrong with the use of lights. The fill 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 greenhouse light in the greenhouse is 12-14 hours in the flowering period, and the winter sunshine in the winter is 5-7 hours. We pass the laser plant growth lamp to compensate for the missing light moments and increase crop yield. Reduce the role of disease. Laser plant growth lights at night fill light is composed of three stages, the fill light stage, the absorption stage and the black period.
