| Abstract | This study was conducted to select the optimal water spray number for the efficient utilization of a pulsatory direct water spray gun system. In order to accomplish the purpose of this research, we evaluated the impingement forces, according to different power pressures, distances, and water spray numbers per second, using a novel pulsatory direct water spray gun system. Based on the result of the basic test, the power pressure and distance of spray that can expect excellent performance were selected as 2 MPa and 1 m, respectively. Then, the flower and leaf bud thinning rate were investigated with different water spray numbers per second under four different flower developmental stages. The optimal water spray frequency for the use of the pulsatory direct water spray gun system was nine sprays per second at the flowering stage, because it resulted in 80% of the flower thinning rate and less than 8% of the leaf bud thinning rate. These results will be used for field applications, which could contribute to labor savings in peach cultivation. |
