The present invention relates to a film for cultivating eggplants that causes less fog and disease, and also provides good coloring of eggplants. Conventionally, agricultural vinyl films, etc. have contained a small amount of ultraviolet absorber, so they have low ultraviolet transmittance, and when used in eggplant cultivation greenhouses or tunnels, the pigment anthocyanin flue is less likely to be produced, which reduces the coloration of eggplants. There was a downside to it being bad. For this reason, films that do not contain ultraviolet absorbers have been proposed as films for eggplant cultivation, but such films have the disadvantage of being susceptible to gray mold, sclerotia, and other diseases due to their large UV transmittance. Ta. As a result of intensive research to eliminate the above-mentioned drawbacks, the present inventors found that the occurrence of gray mold and sclerotium diseases can be prevented by lowering the humidity inside the greenhouse, and the ultraviolet transmittance 7
The present invention has completed a film for cultivating eggplants that suppresses the occurrence of moss in the greenhouse at a concentration of 0% or more, gives good coloring to the eggplants, and reduces the incidence of diseases. That is, the eggplant cultivation film of the present invention contains at least 0.5 parts by weight of a nonionic surfactant and 0.01 to 1.0 parts by weight of a nonionic surfactant per 10 parts by weight of vinyl chloride resin. parts by weight of a fluorine-based surfactant and/or a silicon-based surfactant, and has a transmittance of 70% or more at a wavelength of 35 Kagawa. Vinyl chloride resins that can be used in the present invention include polypinyl chloride and copolymers of vinyl chloride and other monomers, such as ethylene, vinyl acetate, vinyl ether, maleate, and the like. Blends of polyvinyl chloride and other polymers are also not excluded. In addition, plasticizers, lubricants, stabilizers, antioxidants, which are commonly used for vinyl chloride resins,
Pigments, inorganic substances, antistatic agents, etc. can be included. The nonionic surfactants used in the present invention include: 1. Ether type surfactants such as polyoxyethylene alkyl ether, polyoxyethylene alkylaryl ether, and polyoxyethylene polyoxypropylene ether;
'Ester-type products such as polyoxyethylene alkyl esters, partial esterification products of polyhydric alcohols and fatty acids,
{C}Aminoether type such as polyoxyethylene alkylamine, dish polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitol fatty acid ester, polyoxyethylene mannitan fatty acid ester, polyoxyethylene glyceryl fatty acid ester and ether ester types such as polyoxyethylene propylene glycol monofatty acid ester. These nonionic surfactants can basically be selected arbitrarily, but preferably they have properties such as moldability, heat resistance, transparency, etc. in addition to maintaining drip-proof properties, It is desirable that the performance as an agricultural covering material is fully satisfied. Examples of suitable nonionic surfactants for obtaining the above performance include:

If the amount added is less than 0.5 parts by weight, a sufficient drip-proof effect cannot be obtained; If the weight is more than 2 parts by weight, there will be a lot of bleeding, water absorption will cause whitening, and transparency will decrease, which is not preferable. Next, in the present invention, the fluorine-based surfactant added together with the nonionic surfactant is a surfactant characterized by having a fluorine atom in its molecular structure, and representative examples are shown below. tl} Nonionic RfOH Rf-○(CNH2n○)mH Rf(CQ)nOH Rf(C ratio) 10(CnH or○)m Rf(CH2)nCOOH RfBN(R)(C2day○)nH ■Anionic RfCOO M RfBN (R') CH2COOM RfBN (R') C2 ratio○S03M RfS03M Leg strength thione system RfBNH (C2 day 4) Yellow (CH3) 3 words '4) Amphoteric RfBNH (C2 day 4) Yellow (R') 2C2 day 4 COO8

From the point of view of adhesion and weather resistance, it is more preferable to use a fluorine-based surfactant alone, which is effective in a small amount.Examples of the present invention are listed below, but the present invention is limited to these examples. Examples 1 to 3 Films of 0.1 skin were created for the formulations of Examples 1 to 3 in the table, and an eggplant cultivation test was conducted.Comparative Examples 1 to 3 Comparative Examples 1 to 3 in the tables About the formulation 0.1
A skin film was prepared, and an eggplant fruit cultivation test was conducted using the same machine as in Examples 1 to 3. The table shows the results of the actual cultivation tests, which investigated the occurrence of moa, the coloring of eggplants, and the occurrence of diseases.
