Development of zigzag planting mechanism for rice transplanter (Part 2)

摘要

Two types of the zigzag rice transplanter was prototyped. The first one had four planting mechanisms with 45 cm space. It transplanted in a zigzag pattern. A lest field transplanted by the prototype yielded as same as that of conventionaltransplanter with more planting mechanisms. The second prototype has 36 cm of mechanism space, so it is suitable for high density transplanting, such as 30 hills per square meter. Results at field tests showed that high density zigzag transplanting waspossible. A survey at a manually planted field indicated that the yield of high density zigzag planted rice was 10% higher than usual.
