First, the installation cost of cultivated crops is high due to the high installation cost due to the separate installation of feed water pump and pesticide sprayer.

Second, since water or pesticide remaining in the water supply pipe or pesticide supply pipe is dropped into the cultivated crop after spraying or spraying the pesticide, the crop is damaged by local over-pesticide in the soil below the sprinkler, especially the pesticide. If it falls locally, the residual amount of pesticides in the soil and cultivated crops will increase, which may cause the growth of the cultivated crops or lose the commercial value of the cultivated crops, which will cause a decrease in productivity.

Third, because the pump must be operated to obtain pesticide dilution water when spraying pesticides, there is a complicated problem.

In view of the above problems, the present invention is to provide a spraying sprinkling and pesticide spraying device for uniformly and conveniently spraying and spraying pesticides, and can produce cultivated crops at low cost by reducing the cost of facilities such as plastic houses. do.
