In this paper, the Multipurpose Sprinkler Irrigation System applying agricultural medicines in a grape orchard is investigated.
At the facilities, the medicines were mixed with water at terminal pipes, and the orchared were sprinkled from the pressure tank. It is possible to opperate the system by automatic opperation with use of many multipurpose values.
The concentrations of sprinkled fluid were examined by an electric conductance meter to make use of liquid fertilizer as reagentand fluid pressure at the sprinkler nozzle was mesured at the same time. Moreover, the appropriate distribution pattern of sprinkled fluid was examined.
From the test, the following results are obtained;
1) In this case of the Multipurpose Sprinkler System, the measured values of the concentration of sprinkled fluid are obtained highly precise.
2) The uniformity coefficients of sprinkler distribution are attained 79.6% and 85.6% at the set of spnrikler space of 12m×12m, and appropriate pressure are 2.5kg/<cm>^^^2, at sprinkler nozzle.
