State of the art

A traditional large crop field for crops is usually an open agricultural field (open-air cultivation), has a large area and is easily influenced by the climate. Therefore, research institutions in many countries are trying to develop a breeding system to create better environmental conditions to increase yield (especially of food crops) and save energy.

So that the cultivation of crops is not limited by the natural environment and the principle of time- and location-based cultivation can be neglected, the plant breeding takes place in a building under the control of energy sources and environmental conditions for the growth of plants, such as light, water, air and Nutrients to completely eliminate external environmental impact, allowing for continuous harvests throughout the year, increasing yield and saving energy.

However, the conventional plant breeding systems only improve the natural environmental conditions such as light, water, temperature and humidity, especially the lighting and the water supply. The water temperature and air quality are not strictly controlled. If the water temperature and the air quality are not suitable for the growth of the plants, the growth of the plants is weak or fluctuating, so that the yield is not stable.

In addition, the environmental conditions are not the same for the growth of different crops. The same crops also require different environmental conditions at different stages of growth. How to control plant breeding effectively and in a timely manner by adjusting the facilities in the building and overcoming the restriction of plant production by the natural environment has long been a task which industry and science have tried to solve.

The nutrient solution unit 20 contains in the underground at least one reservoir 21 , The reservoir 21 is through a nutrient solution pump 22 and a nutrient solution supply tube 23 with the culture beds 12 connected. Through the earth, the influence of the external temperature is reduced to the nutrient solution, whereby a freezing or overheating of the nutrient solution is avoided, so that the nutrient solution can be kept in a certain temperature. When the temperature of the earth's surface is too low, the reservoir becomes 21 isolated from the earth, creating an additional heating element to increase the temperature of the nutrient solution in the reservoir 21 is not required. Or if the temperature of the earth's surface is too high, the reservoir becomes 21 isolated from the ground, whereby an additional cooling element for reducing the temperature is not required. Therefore, energy is saved, so that the costs of plant breeding are lower. In general, the plants perform photosynthesis to convert first the NPK fertilizer (nitrogen-phosphorus-potassium fertilizer) into amino acid and then amino acid into proteins, lipids and carbohydrates. In the present embodiment of the invention, a biofertilizer (also called microbial fertilizer) is introduced into the reservoir 21 given. Since the biofertilizer was subjected to a second fermentation, the biofertilizer has reached the state of the peptide. In other words, the Biofertilizer was converted to an amino acid after undergoing a second fermentation. The plants can directly add the amino acid in the reservoir 21 absorb with the bio-fertilizer, reducing the demand for the light mask and converting the amino acid into proteins, lipids and carbohydrates. When the bio-fertilizer in the reservoir 21 given, the plants can be stimulated to produce useful secondary metabolites. In addition, the biological sterilization function can be achieved.

Since the diameter of the microbubbles or nanobubbles is small, the buoyancy force is smaller than the normal bubbles by more than three stages (factor 1000), so that the oxygen in the water has a higher stability. The amount of dissolved oxygen in the water has a certain value below a certain temperature, pressure and electrolyte state. The microbubbles or nanobubbles are water-miscible bubbles in the water, whereby the oxygen content in the water is increased and a sterilization and a cooling effect can be achieved.
