The invention discloses an LB light wave optimizing ecological agricultural film for vents and a production technology thereof, which belongs to the field of chemical industry. The LB light wave optimizing ecological agricultural film for the vents is a three-layer coextrusion agricultural film for the vents, wherein, the film is made from Langmuir-Blodgett film (LB), nanometer materials, an ultraviolet absorbent, paint and a light conversion agent by combining an inner adding method. The LB light wave optimizing ecological agricultural film for the vents manufactured according to the method of the invention has cleaner and brighter surface, has the function of optimizing natural light waves, can achieve the effects of long drain and fog dissipation, increases the effect of sterilization and deodorization in the vents, reduces the breeding of pests in the vents, relieves the erosion to the film by pesticide, leads the anti-aging period of the film to be prolonged, decomposes the harmful gases such as pesticide, and the like, in the air of the vents and increases the health of truck farmers, etc.
