Preparation method of nanometer light-converting shed plastic film for kiwifruit planting

The invention relates to a preparation method of a nanometer light-converting shed plastic film for kiwifruits, wherein the preparation method sequentially comprises: modified master batch preparationand nanometer light-converting shed plastic film synthesis. According to the present invention, the nanometer light-converting shed plastic film prepared by the method has characteristics of good gloss and good uniformity, can inhibit the deliquescence of light-converting agents, has a prolonged service life, and still has a good light-converting effect after use for 9 months, wherein the conversion emission spectrum is maximally close to the absorption spectrum of kiwifruits, such that the sunlight absorption and utilization of kiwifruits is enhanced, the phenomenon of infrared radiation isavoided, and the temperature difference between day and night in the shed is low so as to increase the yield of red-fleshed kiwifruits, wherein the yield is up to 5102 kg/mu, and the yield is increased by 28.13%; and the fruit
