What kind of plant production environment can be called plant factory?Bio2 since established in 1987, the United States, although the test finally ended in failure, but the process of human beings have been continuously explore, as greenhouse cultivation, soilless cultivation, artificial lighting, and so on unceasingly in the field of rapid development, the concept of plant factory experienced from clear to fuzzy, and again from fuzzy to clear process.
At first clear was the ideal of Bio2, which was simply a mini-earth;It's fuzzy because Bio2 failed;It is now becoming clear that rapid technological advances on all sides have made the Bio2 ideal feasible in many ways, but not too harsh.
How do you define a plant factory?According to the current trend of plant factory development in various countries in the world, a plant factory should have at least the following conditions:
(1) It can realize the continuous production and operation of crops in an infinite cycle;
(2) Nearly fully automatic control of the internal environment of the factory, including lighting, carbon dioxide concentration, temperature, humidity, nutrient solution, etc.;
(3) Not affected by natural conditions, almost completely divorced from natural conditions;
(4) Automatic control of production line, from pre-production, production to post-delivery and so on;
(5) While the production efficiency is significantly higher than that of traditional cultivation, it is necessary to ensure that after the plant plant operation is mature, the cost is lower than that of traditional cultivation, the crop quality is better than that of traditional cultivation, the energy consumption is lower than that of traditional cultivation, and the environmental pollution is lower than that of traditional cultivation.
In the final analysis, plant factory is a plant planting system that can realize the continuous production and operation of crops in an infinite cycle, separate from the influence of natural conditions, and fully realize automatic control, which is beneficial to human beings and the earth.
To be precise, the current plant factory can not be called a plant factory in the true sense, but only the transitional existence of the plant factory. Although the emergence of LED plant lamp dispelled many concerns when using traditional plant lamp, it also completely overturned the concept of "everything grows by the sun" in the real sense.It can be said that the emergence of LED plant lights promoted the development of plant factories a big step.
However, a revolution in plant cultivation, which will take decades or even hundreds of years, cannot be fully controlled by a small LED plant lamp.
In terms of the current state of plant factories, the production cost is very high, the statistics of growth conditions in different growth periods of various plants are not complete, the crops with statistical data are not completely stable output, and the semi-automatic control mode of plant factories is not fully mature.
Moreover, the most important point is that the current plant factories consume much more energy and pollute much more than the traditional farming methods. According to the statistics of American scientists, if the current plant factories grow rice, which is required to satisfy the entire population of California for a year, the electricity consumption is twice the total annual electricity consumption of the whole United States.Waste gas pollution is far greater than traditional farming.
With LED plant lamp plant factory development can smooth sailing?No, there are still many difficulties to overcome in the future. I only hope that the plant factory in the real sense can be realized as soon as possible. I only hope that in the society obsessed with profit, the great countries, scientists and capitalists should not forget that we all live on earth.Plant factory built a day, do not destroy the earth's environment at the cost of.
