An experimental planting-mechanism to be applied for the planting of taro-seeds was developed, with examinations of delivery performances and planting-accuracy of the device.
The results obtained are as follows.
1. The delivery-rate of the single seed and the delivery-rate of the zero seed (Variety: Daikichi; 90-92%, 6-7% Ishikawawasemaru; 85-89%, 8-9%, respectively) were obtained under the circumferential bucket-conveyor-speed of 10.6-12.7cm/s.
2. The proper planting-rate of the individual seed (Variety: Daikichi; 96-97% Ishikawawasemaru; 90%, respectively) was obtained under the circumferential planting-roll-speed of 14.4-17.3cm/s.
3. In order to develop a taro planter of high performance, the effect of the field test and the durability of the planting-mechanism must be investigated in the near future.
