Plant fill lights are effective and have certain uses, but they have little effect.
When plants are growing, if there is insufficient external light, they need to use plant fill lights. The luminous body of the plant supplementary light is a light-emitting diode, which can supplement the light for the plant, allowing it to carry out photosynthesis and accumulate nutrients. During the maintenance period, if the power of the supplementary light for the plants is too low, the light will be weak and have little effect on the plants.
Development Prospects
At the same time, modern greenhouses are widely used in countries around the world to increase yields by creating conditions suitable for crop growth. The Netherlands has built 110 million square meters of glass greenhouses, accounting for a quarter of the world's total greenhouse area. It ranks third in the world in terms of agricultural exports and has achieved significant yield increases. For example, the unit yield of peppers in the greenhouse has reached 30kg/m2, and the yield of tomatoes has reached 30kg/m2. The unit output reaches 60-70 kg/m.
The United States has built a "sapling factory" in Santa Pola, Los Angeles. It uses bioengineering methods to cultivate fruit tree saplings with single cells, achieving large-scale industrialization. High value-added agricultural products such as vegetables, fruits and flowers in developed countries are mainly supplied by greenhouses. High-efficiency agriculture cultivated in greenhouses is an inevitable trend in modern agriculture.
