Abstract

The invention discloses a novel imitative-ecological double-band light-energy conversion agricultural film and a production technology thereof. The light conversion film has long service life and good light conversation performance, a light conversion agent used has low production cost and amount and the mixing ratios of re-light conversion agent and the blue-light conversion agent can be regulated according to different types of plants so as to more effectively use the sun light. The production technology comprises the following steps: light stabilizer, thermal stabilizer, dripping agent, mixed light conversion agents and the like are weighed according to a respective ration against resin, are added into a plasticator, and stirred in a high speed with the stirring speed being controlled; the temperature is controlled till the resin taking the shape of plasticized state; the mixture is discharged and put into a granulation extruder for granulation; and then various types of resins and master batch are weighed accurately, according to the requirements of a technological formula, put into a stirrer for stirring and added into an extruder for extrusion, and coiling, coil stripping and packaging are carried out finally.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a novel ecological imitation dual-band light energy conversion agricultural film and a production process thereof. Background technique [0002] In addition to light intensity and photoperiod, light quality is an important factor for plants' demand for light energy. It not only affects the photosynthetic efficiency of crops, but also regulates the growth of crops. The chlorophyll of green plants has different degrees of selective absorption of light of different wavelengths. The light-changing agent can absorb the destructive near-ultraviolet light in sunlight, and emit the blue-violet or red-orange light most needed in the photosynthesis process of chlorophyll to complete the photoconversion. So far, most light-converting films only convert ultraviolet light into visible light of a single band, such as red-orange light or cyan-blue light, especially red-orang...
