PROBLEM TO BE SOLVED: To spray a chemical liquid to a tea plant cut surface after cutting in a shortest possible time to prevent occurrence of gray blight of the tea plant after cutting a tea branch/leaf since the gray blight is a sickness causing large damage to a tea variety of "Yabukita".SOLUTION: The tea field work machine is constituted by: a travel machine body causing a portal type machine body to straddle a tea plant ridge and travel a cutting work machine arranged in the travel machine body and including a cutting blade cutting a tea branch/leaf and chemical liquid spray means formed as an attachment. The tea field work machine performs cutting of a tea branch/leaf and spraying of a chemical liquid to the tea plant cut surface having been cut, during the same traveling.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 茶品種の「やぶきた」にとって、輪班病は被害の大きな病気であるため、本発明は、茶枝葉を切断した後の茶樹の輪班病の発生をなくすことを課題としており、そのために、切断後の茶樹切断面にできる限り短時間で、薬液の散布をおこなうことを課題としている。【解決手段】茶樹畝を跨いで門型の機体を走行させる走行機体と、該走行機体に設けられる、茶枝葉を切断するための刈刃を備えた切断作業機と、アタッチメント化された薬液散布手段とより構成し、茶枝葉の切断と、該切断した茶樹切断面に対する薬液散布とを同一走行間におこなうことを特徴とする茶園作業機。【選択図】図1
