Abstract

The invention discloses a light-converting transparent plastic greenhouse film for cucumber planting. The light-converting transparent plastic greenhouse film comprises the following components in parts by weight: 65-75 parts of low density polyethylene, 10-20 parts of calcium stearate, 5-10 parts of a titanate coupling agent, 10-12 parts of N-methyl-2-dihydrogen pyrrolidone phosphate, 20-30 partsof starch, 15-20 parts of polyvinyl alcohol, 10-20 parts of cotton fibers, 5-10 parts of glacial acetic acid, 5-10 parts of acetic anhydride, 3-5 parts of a plasticizer, 3-5 parts of a flexibilizer and 3-5 parts of a dispersing agent. The transparent plastic greenhouse film disclosed by the invention is capable of increasing yellow, red and orange light, eliminating green and purple light and promoting budding and flowering of cucumbers, and the effect of increasing yield is achieved, the utilization rate of sunlight is improved, the service life of the greenhouse film is prolonged, and the aging rate of the greenhouse film is effectively retarded.
