This study was conducted to increase the control efficiency of domestic apple orchards by improving the morphological improvement of air-blast sprayer and reducing the amount of pesticide spraying in line with the domestic apple orchard system changing from the large tree to the high density apple orchards.
As for the spraying pattern according to the type of air blast sprayer, the spray amount of the axial-type air blast sprayer steadily decreased as the higher the height of the tree, resulting in a large gap between the upper and lower parts, but the tower-type air blast sprayer was evenly sprayed. Although there was no significant difference in shape of the air blast sprayer in the blast distribution, the left and right blast distribution was found to be more uniform than the axial-type air blast sprayer due to the design characteristics of the tower-type air blast sprayer. The nozzle pressure showed high injection pressure, even though the axial-type air blast sprayer was the same rpm as the tower-type air blast sprayer.
In the case of the type of sprayer and the coverage rate of each nozzle, the coverage rate was higher for both 5,000 L/ha, but at 3,000 L/ha, the coverage rate difference between the top and bottom of the canopy was larger than that of the regular nozzle-modified axial and tower-type air blast sprayer.
In the same 1800 L/ha volume in different orchard systems of 3.7x1m and 3.6x1m and the covering rate test using tower-type air blast sprayer, both orchard systems showed effective covering rates, but 3.6x1m orchard system was more evenly distributed.
