摘要

本試驗目的為研發擺動噴頭機構並與設施內自走式自動噴霧裝置整合，探求整合後的系統性能，及葉面的霧粒附著噴霧效果。開發完成之擺動噴頭機構雛型裝置重約76kg，而未裝設擺動噴頭的噴架重約30kg，兩者重量上有顯著差異，但是兩者噴架行走速率相差在2%以內，顯示行走性能方面並無太大差異。葉表面噴霧附著度測試結果顯示噴架速率在2.16km/hr（變頻器頻率60Hz）時，擺動噴架每分鐘來回擺動118次，葉下表面附著度為44%，較不擺動噴架的33%為高；噴架速率在1.07km/hr(變頻器頻率30Hz)時，擺動噴架每分鐘來回擺動58次，葉下表面附著度為67%，亦較不擺動噴架的46%為高，顯示噴頭擺動之噴霧附著效果確實較不擺動的噴架好，並且低速有較佳附著結果。

The aim of this experiment is to develop a swaying nozzles carrier and to evaluate the moving and spraying performances of the carrier with the self-propelled spraying equipment. The swaying nozzles carrier has the weight of 76kg, and is heavier than a nonswaying nozzles carrier (30kg). The speed of the swaying carrier is from 0.71 km/hr to 4.21 km/hr, but the speed difference of these two carriers is lower than 2%. There is not significant traveling speed difference between these two carriers.When swaying nozzles carrier traveling at 2.16km/hr (60Hz), and swaying times is 118 per minute, the deposition on leaf back surface is 44%. It is greater than 33% of a nonswaying carrier. When carrier travelinging at 1.07km/hr (30Hz), and swaying times is 58 per minute, deposition on the leaf back surface is 67%. It is greater than 46% of a nonswaying carrier. The results indicate that the deposition on dorsal leaf surfaces are higher than 96%. The swaying nozzles carrier at lower speed can improve deposition on leaf back surface in the rose culture.
