Research overview:
The number of harvested mandarin orange declines every other year owing to abnormal climate such as drought and the like and insufficiency in management caused by shortage of labor force. Therefore, management of farmhouse has become unstable because the price of mandarin orange has been lowering. To cope with such situation, we establish stable continuous production engineering that can cope with the change in climate, and simplify techniques using sprinkler and the like which utilizes irrigation canal. We also verify stable production engineering to continuously produce mandarin orange that contains high sugar so as to strengthen systematic production and shipment system.
