Plant factory is the product of industrialization of agricultural planting and the development direction of vegetable planting in the 21st century. It marks the advanced stage of facility agriculture development and is the most valuable new industry for investment in the next 10 years. The establishment of greenhouse light supplement lamp for vegetable production in cities has become a new field for the development of countries all over the world.
The main reasons why plant factories have become hot spots of investment are as follows:
1. The uncertainties of global climate change are increasing. The decrease of water resources and desertification of land make traditional agriculture encounter difficulties.
2.the logistics cost of urban vegetable supply has increased, and the price of urban vegetable has risen, which provides profitable space for products.
3. The use of pesticides and insecticides in vegetable cultivation in pursuit of yield has raised concerns about vegetable pollution.
4.the growing environment deteriorated, food safety, increased medical costs and other requirements for vegetable safety increased.
5.the urbanization process has brought about an increase in urban population, an increase in vegetable supply, while land resources have been decreasing.
6. The environmental burden caused by traditional agricultural production is increasing.
The most important feature of LED plant lamp is to break the traditional vegetable production mode, through the automatic control of plant photosynthesis, temperature, carbon dioxide concentration, nutrient solution and other high-efficiency planting, to achieve ordered production, vegetable production cycle will not change because of weather and other reasons, the vegetables produced are truly safe vegetables. Vegetables, with the gradual expansion of the application of LED plant light supplement lamp based on LED technology, plant factories will usher in the golden period of development.
