为了优化水稻碗盘式精密播种机的参数，提高其性能，分别在5个水平上对影响水稻精播机排种量的3个主要因素：定径、种子垂直位移和凸轮转速进行了试验，并进行了二次正交旋转回归试验，研究了这些因素对排种率、漏播率和伤害率的影响。试验结果表明，影响水稻播种率的因素大小顺序为：成型孔直径、凸轮转速和水稻种子垂直位移。影响水稻插秧渗漏率的因素依次为：成孔直径、水稻种子垂直位移和凸轮转速，影响水稻伤害率的因素依次为凸轮转速、水稻种子垂直位移和水稻成孔直径。优化的参数(定径10 mm，水稻种子垂直位移27 mm，凸轮转速13r/min)和性能指标(播种率95.43%，漏播率0.37%，损伤率0.58%)为水稻碗盘式精密播种机的设计和性能改进提供了依据。
In order to optimize the parameters of bowl-tray rice precision seeder and improve its performance, three major factors respectively at five levels, including shaped hole diameter, vertical displacement of rice seeds and rotating speed of cam, were tested, the quadratic orthogonal rotational regression experiments were conducted, and the effects on seeding rate, leakage sowing rate and the injury rate were investigated. The test results show that factors affecting rice seeding rate are in the order of shaped hole diameter, rotating speed of cam and vertical displacement of rice seeds. The factors affecting rice planting leakage rate are in the order of shaped hole diameter, vertical displacement of rice seeds and rotating speed of cam, and the factors affecting rice injury rate are in the order of rotating speed of cam, vertical displacement of rice seeds and shaped hole diameter. Optimal parameters (shaped hole diameter: 10 mm, vertical displacement of rice seeds: 27 mm, rotating speed of cam: 13 r/min) and performance index (seeding rate: 95.43%, leakage sowing rate: 0.37%, injury rate: 0.58%) provided the basis for design and performance improvement of the bowl-tray rice precision seeder.
