[Industrial Application Field] The present invention relates to an agricultural covering material used for covering agricultural tunnels, simple greenhouses, and the like. [Prior art and problems to be solved by the invention] Vinyl chloride resin films or sheets are widely used as covering materials for agricultural tunnels, simple greenhouses, etc. because they are inexpensive, transparent, and have excellent heat retention and strength. However, vinyl chloride resin has problems with weather resistance, and its physical properties deteriorate due to exposure to sunlight, resulting in a decrease in transparency, and its strength decreases, making it susceptible to holes forming where it comes into contact with the frame of a house, etc. There are drawbacks such as: For this reason, conventionally, ultraviolet absorbers are added to resins to improve their weather resistance, but adding ultraviolet absorbers reduces the amount of ultraviolet rays transmitted, resulting in color discoloration of eggplants, strawberries, and flowers. The big problem was that it was getting worse. On the other hand, an eggplant cultivation film with a transmittance of 70% or more for ultraviolet light with a wavelength of 350 nm has been proposed to improve the coloring of eggplants (Special Publication No. 60-28860).
issue). However, conventionally, in order to improve UV transmittance, weather resistance had to be sacrificed.
It has been desired to develop a fog-proof agricultural covering material that has both excellent ultraviolet transmittance and excellent weather resistance. [Means for Solving the Problems] The present invention solves the drawbacks of the above-mentioned prior art, and provides fog-proofing properties that can simultaneously satisfy the problems that could not be met at the same time, such as excellent ultraviolet transmittance and excellent weather resistance. As a result of intensive research to develop agricultural covering materials, we have found that by incorporating specific amounts of hydrotalcites, higher alcohol phosphate ester metal salts, and specific fluorine-containing compounds into vinyl chloride resin, we have improved the transparency of ultraviolet rays. The present invention was completed by discovering that weather resistance can be improved without degrading it. That is, in the present invention, per 100 parts by weight of vinyl chloride resin, the formula:
[(M 1 ) a (M 2 ) b (M 3 ) c ] 1-x Alx(OH) 2 A n- x/o・mH 2 O (1) (0<x≦0.5, 0.5≦a+b+c< 1.a

Each film was used as a covering material for pipe houses, and in 1986,
Exposure tests were conducted from March 10th to December 20th of the same year to evaluate weather resistance. The fog-proof properties of each film were tested by spreading them in a tunnel house. The ultraviolet transmittance of each film was determined by measuring the ultraviolet transmittance (%) at a wavelength of 350 nm using a spectral light transmittance measuring device. The results are also shown in Table 2.
