Description of the Related Art Conventionally, there has been a method for cultivating vegetables in a greenhouse made of a synthetic resin film such as polyvinyl chloride, polyethylene, or a copolymer of ethylene and vinyl acetate, which enables cultivation even in low temperatures. Has been taken. In this case, since the synthetic resin film used needs to always transmit sunlight, a method of kneading an antifogging agent in advance is used to prevent the occurrence of clouding due to water on the surface of the synthetic resin film. Examples of the antifogging agent include higher fatty acid esters such as polyethylene glycol, glycerin, sorbitan, and sorbitol, and ethylene oxide (hereinafter referred to as EO) in addition to these higher fatty acid esters.
Or) propylene oxide (hereinafter referred to as PO) has been used as a nonionic surfactant.

The lack of sustainability in Japan has come to be pointed out. On the contrary, it has been pointed out that the improved high temperature durability has a poor initial effect and low temperature effect.
