The development trend of the greenhouse light

In recent years, with the improvement of agricultural productivity, domestic greenhouse light has developed rapidly. The reasons are as follows: (1) in order to enliven the market of flowers, fruits and crops, greenhouse is used to produce off-season crops; (2) Spring seedling raising of rice and other fruit vegetables; (3) High-tech plant factories that artificially control crop growth conditions meet the needs of the development of ecological agriculture such as soilless cultivation and green food.

At the same time, modern greenhouses lights are widely used all over the world to increase production by creating conditions suitable for crop growth. The Netherlands has built a 110 million M glass greenhouse, accounting for one quarter of the total greenhouse area in the world. Its agricultural export ranks third in the world and has achieved obvious yield increasing benefits. For example, the unit yield of pepper in warm room is up to 30kg / M and that of tomato is up to 60-70kg / m. The United States has built a "seedling factory" in San Paula, Los Angeles, using bioengineering means to cultivate fruit tree seedlings with a single cell, realizing large-scale industrialization. High value-added agricultural products such as vegetables, fruits and flowers in developed countries are mainly supplied by greenhouse. High efficiency agriculture cultivated in greenhouse is an inevitable trend of modern agriculture.
