The light conversion agricultural film mainly comprises a light conversion agent master batch, and the light conversion agent master batch comprises, by mass, 10-50% of the nitride red light conversion agent, 1-10% of an assistant, and the balance of a master batch matrix. The nitride light conversion agent well matches with spectra required by plant photosynthesis, has excellent red long afterglow luminescence performance through trivalent rare earth ion co-doping and cation replacement, and can provide red orange light required by plant photosynthesis for a long time under night or sunless conditions to prolong the plant photosynthesis. The nitride light conversion agent is processed to form the master batch, and the master batch is used to make the agricultural film, so the light conversion agent is pre-dispersed, thereby the dispersion of the nitride light conversion agent in the film matrix is improved, and yield increase and quality improvement effects are reached when the agricultural film is applied in the agriculture field.
Description
Technical field
The invention belongs to agricultural light-light conversion field of functional materials, particularly a kind of optical transfer agricultural film and preparation method thereof and application.
Background technology
Agricultural rare-earth luminescence-light conversion agent is also referred to as agricultural light-converting agent.When agricultural light-converting agent is through being processed as optical transfer agricultural film and for proportion of crop planting, can by the light being partially converted to the absorption of plant-growth needs useless or harmful to plant-growth in sunlight; In addition, there is the light-converting agent of obvious twilight sunset effect, booth implants photosynthesis still can be made to carry out efficiently for during light deficiency under field conditions (factors).Therefore, agricultural light-converting agent and optical transfer agricultural film are as a kind of high technological aqriculture light filling material of effective raising chamber crop output, under the background that traditional agriculture tillage system reform can not meet modern society's demand, more and more become the new trend that current photoelectric technology is applied at agriculture field.
The light of heterogeneity is different to the growth of plant.The royal purple light of wavelength 400 ~ 480nm by chlorophyll, carotenoid strong absorption, can promote the cauline leaf growth of plant; The blood orange light of wavelength 600 ~ 700nm, by Chlorophyll absorption, can promote the fruit growth of plant; The yellow green light of wavelength 500 ~ 600nm to photosynthesis almost without contribution; And the near-ultraviolet ray of wavelength 315 ~ 400nm except the light near 360nm to promotion fruit painted useful except, remaining all can make plant become short, blade is thickening; The ultraviolet of wavelength 290 ~ 315nm is all harmful to most plants, can impel plastic sheeting for farm use degeneration and wane.Desirable light-converting film can by plant-growth is harmful to and the light that cannot absorb be converted to the royal purple light and blood orange light that the green element of Photosynthesis can absorb, thus the light quality changed through the light of optical transfer agricultural film, promote that plant is to the absorption of the nutritive elements such as nitrogen, phosphorus, potassium, zinc, improve blade area and the expansion degree of plant, increase plant height and the petiole length of plant, increase the content of leaf chlorophyll thus, the photosynthate content in blade is raised, promote plant growth.
