In winter, greenhouse vegetables equipped with supplementary lighting equipment are better than those unused. This is because vegetable growth requires relatively fixed light intensity and quantity. And to meet this demand for vegetables, vegetables naturally grow vigorously. So, grape light supplement lamp, how to use the light supplement lamp to achieve the desired effect?
Supplementary lamp to provide light for vegetables is not constant distance, need to be flexible adjustment according to the height of vegetable growth.
Under normal circumstances, the supplementary lamp with large irradiation range is far from the vegetable, and its height is about 1.5-2 meters away from the growing point. The supplementary lamp with small irradiation range is usually installed at the distance of 0.5-1.5 meters above the vegetable growing point. Therefore, when installing the light supplement lamp, the pulley is used for lifting, so that the rope can be disassembled conveniently to adjust the distance.
lighting time is not fixed, it needs to be flexibly adjusted according to the needs of vegetable light intensity. For example, cucumber under short-day conditions is conducive to female flower differentiation, so when the light intensity is weak, it can be supplemented accordingly, so as to improve photosynthesis and yield. But we should pay attention not to extend the length of illumination indefinitely. In the absence of precipitation, the scattered light can be seen in the pullable shed and the supplementary light can be turned off.
