<；P>；PROBLEM TO BE SOLVED: To provide a blowing apparatus for solving such problems that a vent duct is conventionally arranged between the legs of an elevated cultivation bench to directly spray to strawberry or the like from the opening of the vent duct for local blowing between stocks, and a culture medium cooling device includes a saucer and a nonwoven fabric for wrapping culture medium set on a saucer, and includes cooling culture medium together with blowing for facilitation of installation, lowering cost, and wide installation, but local blowing between stocks is partly possible but hardly sufficient yet. <；P>；SOLUTION: The blowing apparatus of a greenhouse of tomato stocks has such a configuration that a suction fan is installed in a greenhouse wall in a greenhouse for a plant shelf and ground cultivation of tomato stocks, a duct connectedly installed on the fan is extended to the ridge direction of the greenhouse, and many branch ducts installed on the duct are moved in the same period of the growth of tomato stocks. Blowing from the blasting hole of the branch duct is performed towards the calyx (tomato) or leaf joints of the plant so as to destroy air accumulation on the leaf surface of the plant. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
