Rice Precision Transplanting as Achieved by Use of Mechanical Transplanting Regular Drilling and Transplanting Machines

Technology achieving precision transplanting of rice seedling of 2-4 seedlings per hole and average 3 seedlings per hole was introduced. It uses a complete set of 2BSP- 500A rice planter with a few additional parts recombined to form a new planting process so that precision drilling of prenursery tray can be obtained. The tray then can be used satisfactorily to give precision transplanting with regular rice transplanting machine without modification. Theoretical analysis of the new functional parts was carried out to determine the main parameters of their design. Performance tests for drill planting and transplanting were conducted showing satisfactory results
