The fill light is an agricultural facility that can provide a light source for the normal growth of vegetables. In recent years, it has been widely used in greenhouses. Many vegetable farmers have installed various kinds of fill light in their own greenhouses. In fact, the use of fill light is flawed, but it is not used casually. There are many details to be paid attention to during the use process. How do you use the fill light in the greenhouse? Here are some details about the use of fill light in the greenhouse.
The fill distance should be flexible.
Some vegetable farmers have installed a fill light. Because of the large area of the greenhouse, the number of used fill light is huge, and it is often not adjusted after installation. The distance that the fill light provides light to the vegetables is not static and needs to be flexibly adjusted according to the height of the vegetables.
Under normal circumstances, the fill light with a large illumination range is far away from the vegetable, and the height is kept at a distance of 1.5-2 meters from the growth point. The fill light with a small illumination range is generally installed at a distance of 0.5-1.5 meters above the growth point of the vegetable. . If it is a simple fill light, it can be slightly closer to the growth point of the vegetable. If it is a light fixture with both light filling effect and warming effect, it needs to keep a certain distance from the vegetable growth point to avoid damage to vegetables too close. . If the distance is too far, the fill light will be reduced.
This distance is also subject to flexible adjustments depending on the growth height of the vegetables. Therefore, when installing the fill light, it is best to use a pulley to hoist it, so that the rope can be disassembled to adjust the distance.
The length of fill light should be flexible.
The fill time of the fill light is not fixed, and it needs to be flexibly adjusted according to the demand of the light intensity of the vegetables. Due to the different origins of vegetables and different climate adaptability, the requirements for the length of light are different. They can be divided into three categories: one is long-day vegetables, the other is short-day vegetables, and the third is Chinese-Japanese vegetables.
Eggplant requires higher light intensity and length. The light saturation point is 40,000 to 50,000 lux, and the light compensation point is 2000 lux. Under natural light, the longer the sunshine time, the stronger the fertility, the better the flower bud quality, the flowering period is advanced, and the yield is high. The sunshine time is shortened, the growth and development are poor, the growth is weak, the flower bud differentiation is delayed, the flowering rate is high, and the fruit is poorly developed. According to the above growth habits, the illumination can be enhanced at any time of the day, and the effective illumination time can be prolonged, such as when the length of the cloudy or winter sunshine is insufficient and the intensity is insufficient, so as to maximize the photosynthesis.
The light saturation point of the tomato is 70,000 lux and the light compensation point is 2000 lux. The daily sunshine hours are 12 to 14 hours, and the light intensity of 40,000 to 50,000 lux is the ideal lighting condition for tomatoes. If the light is weaker than 1.3 lux, the flower bud differentiation is greatly delayed. Even if the nitrogen fertilizer is added, the influence of such weak light can not be overcome, and it is easy to fall. Tomatoes are not strict with the length of light, and increase the photosynthesis time, which is beneficial to the formation of flower buds and the growth of plants.
According to the data, in a cloudy day, the yield of cucumber can be reduced by one-third after one day. After several cloudy days, the yield is almost no. If the cloudy time is too long, it will bring serious consequences to cucumber production. Cucumber is beneficial to female flower differentiation under short daylight conditions. Therefore, in the daytime, when the light intensity is relatively weak, the corresponding fill light can be performed, thereby improving photosynthesis and increasing the yield. But be careful not to extend the length of the light indefinitely, so as not to affect the yield only if it is not long.
Pay attention to moisture
Because the humidity in the greenhouse is higher than the outside, when the fill light is selected, the moisture of the lamp should be protected to extend the service life of the fill lamp. It can seal the luminaire or choose a fill light with good waterproof and moisture resistance. Of course, not only the lamps should be well protected from moisture, but also the wire connectors and lamp holders and switches used to fill the light in the shed should be protected from moisture.
In addition, in order to improve the light-filling effect, a reflective film can be laid on the ground to improve the light-filling effect of the middle and lower blades.

Good quality fill light can supplement the shortage of light for vegetables in the case of less light in winter, ensure the normal photosynthesis, and achieve the normal growth and flowering results of vegetables.
