水稻钵苗行栽机试验

Experimental study on rice potted-seedling transplanter

介绍了研制成功的水稻钵苗行栽机的构造和工作原理,以及样机的性能指标检测和生产试验.试验结果表明该机的检测项目均达到或超过设计指标,满足水稻生产要求;采用水稻钵苗行栽机作业与人工抛秧相比具有生产效率高、秧苗分布均匀、直立度好等特点;与插秧相比具有栽植深度适宜、植伤轻、缓苗快的优点,作业质量显著提高;每公顷可增产558kg,增产幅度达到10.0%,具有明显的增产效果.水稻钵苗行栽机是目前较为理想的一种水稻移栽机械.

The structure and operation principle of rice potted-seedling transplanter are introduced, and the performance measurement of the prototype and the production testing are conducted. The experimental results prove that the machine has reached the design index and can meet the rice production demand. Compared with the manual throwing rice seedling, the rice potted-seedling transplanter has the characters of high production efficiency, evenly distributed rice seedling and well upright degree. Compared with rice transplanting, this machine has advantages of suitable planting depth, less damage on the seedling, fast recovery, and notably-improved working quality. The yield can increase up to 558 kg/hm2, and the percentage increase is up to 10.0%, which has obvious effect in increasing the yield. It will be an ideal rice transplanting machine at present.
