Abstract;For the purpose of labor saving of plucking and skiffing work of tea in a tea garden of an intermediate hillside slope place, we carried out investigations on basis preparation conditions, elucidation of using method of small-sized riding-type tea plucking machine, and management evaluations of conditions of establishment by individuals and introduction of riding-type machines. As the results, the following became clear. 1) In the prefecture, the complex formation was general, wherein there are numerous tea gardens of gentle slope of 6.DEG. or less of tilting, and wherein gentle-steep slope tea gardens of around 15.DEG. of tilting, or steep slope terrace tea gardens of 18.DEG. or more of tilting were scattered in the peripheral parts. Tea field establishments by individuals were performed at places of topography where the slope was 15.DEG. or less, and they were arranged to 1-5.DEG.. Terraces after preparations had shapes following the original topography, and the terrace surface rate was 89.6% in the average to the original topography. Further, as pillow places for turning a machine were taken, and the planting rate of terrace surface became 88.7% in the average. Such problems were seen, the slope gradient after preparation was a little steep and there were few preparation of drainage canal, and there was an example that a work path, etc. between terraces had a steep slope. 2) As for the small-sized riding-type tea plucking machine, a large scale labor saving was possible in plucking and skiffing work. However, the load to an operator was larger than that of traditional plucking machine for two persons, power tea pluker in plucking work. As for plucking travel speed, 0.3 m/s was appropriate for the primary tea, and 0.4 m/s for the secondary/tertiary tea. As for the housing capacity of green leaves, 18 kg was suitable for one bag, because it took more time in exchanging bags as the capacity of one bag increased.... (author abst.)
