摘要
对2QXP-1型气吸式精密排种器构造、工作原理和工作性能影响参数进行了分析,应用正交试验的方法研究排种盘转速和真空室气压变化对排种性能的影响。试验表明：对排种性能影响的主次因素顺序为排种盘转速、真空室气压。
The structure and working principle of 2QXP-1/2 type suction-seed metering device were introduced, and the influencing parameter of working performance was analyzed theoretically. The effects of the speed of planter plate and vacuum degree on seeding performance were studied with orthogonal experiments. It indicates that the order of primary and secondary factors affecting planting seeds is rotation speed of planting plate and pressure of planting respectively .
