"Physical fertilizers" will show their skills
Hebei University’s Physics took the lead in developing “Physical Fertilizersâ€. It is different from ordinary fertilizers and it is not a supplement to the soil. Instead, they aim at the demand and joy of crops for light, and use various monochrome cold light pipes to accelerate the biochemical melons in the plants through the action of light, so that the crops can be absorbed and utilized more fully. This "light fertilizer" consists of short-wavelength red, blue, violet and other luminous tubes, which can make up for the lack of red light and blue light in the greenhouse. The power consumption of a set of eight glass tubes is 60 watts. Light bulbs, 333.5 square meters (half amu) of greenhouses cost 700 yuan to install two sets is enough, you can make the crop mature period 7-10 days in advance, the output increased by 20% -30%. At present, foreign countries are actively developing and using “physical fertilizers,†which use light, sound, electricity, and magnetism in different wavelength bands, different intensities, and different frequencies to act on plants. This not only shortens the maturation period, but also significantly increases production and improves fruit quality. It can improve the disease resistance of crops and has no pollution to soil and environment. Experts predict that at the beginning of the next century, physical fertilizers will play a major role in agriculture. Hebei University’s Physics took the lead in developing “Physical Fertilizersâ€.
