其他摘要：The purpose of this study is to clarify the bottleneck elemental works in planting using containerized seedlings. For this purpose, the total number of 16 people planted containerized seedlings using 4 implements (hoe, dibble, spade, and planting tube), and we analyzed working efficiency and elemental works with the 4 implements. The results showed that the highest working efficiency is the hoe. The working efficiency of pitting with a dibble or spade or planting tube is lower that those of pitting with a hoe. The working efficiency of planting with planting tube is lower than that of planting with hoe. The work time to tread down around a seedling and the work time to move to the next planting ground is not affected by the difference in the planting implements. We show that the efficiency improvement of the pitting and planting is necessary for the high efficiency of the planting work using planting implements besides the hoe.
