Problems solved by technology

In the existing technology, photovoltaic greenhouses are built mainly by laying photovoltaic modules on the top of agricultural greenhouses. However, there is a phenomenon of competition between photovoltaic power generation and plant growth, which cannot meet the growth requirements of light-loving plants. Due to the constant temperature inside the greenhouse, only a single crop can often be planted. It is difficult to provide abundant food for the flock. The second type of photovoltaic greenhouse is behind or in the middle of the photovoltaic module greenhouse. Although there is no problem of smearing light, there are many columns in the greenhouse and the height of the greenhouse is low, which is not conducive to the operation of agricultural mechanization.
In addition, photovoltaic modules on photovoltaic greenhouses can absorb ultraviolet and infrared rays in sunlight, which weakens the bactericidal effect of sunlight. Therefore, the soil in the greenhouse is prone to breed a large number of harmful bacteria and reduce the yield of forage
[0003] The patent with the application number CN201410362799.9 discloses a method for large-scale and standardized breeding of beef cattle and sheep with photovoltaic facilities. The organic combination of traditional agriculture and photovoltaic power generation is realized by building photovoltaic greenhouses. The light transmittance of thin-film solar panels is better, reducing the The shading area, but the panel can absorb ultraviolet rays with a wavelength lower than 400nm, absorb all the ultraviolet rays of 287-390nm in sunlight, greatly increase the content of harmful microorganisms in the soil, and increase the incidence of crops. In addition, the closed The greenhouse structure is not conducive to the operation of agricultural mechanization
