Development of a precision direct drill seeder for direct sowing of rice on paddy field (Part 4) - regional adaptability of development seeder

摘要

This study was carried out to develop precision direct drill seeder with controls of seed depth for direct sowing of rice on paddy field. This performance will exert influence on the stable germination by decreasing an inappropriate germination. The developed 8-row or 10-row seeders were investigated in the regional adaptability tests to support commercial enterprise of the developed seeders smoothly. These seeders were evaluated by user about the operational performance and the durability. The result were summarized that the developed machine have worked many fields under high accuracy, and some improvement points were cleared. The developed seeder was put on to the market in spring 2000.
