摘　　要：为改变现有油莎豆排种技术,实现精准精量排种,提高油莎豆播种质量、播种效率及综合经济效益,通过对油莎豆籽粒的三轴尺寸物理测量,改造了排种盘,设计并搭建了试验台。单因素试验与正交试验优化验证得出,排种盘最佳工作参数为气吸盘孔径6.5 mm、转速25 r/min、负压值6.5 kPa,漏播率为0.52%。该气吸式排种盘实现了高效精量排种,并符合油莎豆播种技术要求,为油莎豆播种机气吸盘式排种器的选择提供了依据。In order to change existing seed metering technology of Cyperus esculentus,achieve precise seed metering,improve seed quality,seeding efficiency and comprehensive economic benefits of Cyperus esculentus,through physical measurement of three-axis size of Cyperus esculentus,seed metering disk was modified,test platform was designed and built.Single factor test and orthogonal test optimization verification showed that the best working parameters of seed metering disc were 6.5 mm diameter of air suction disc,25 r/min of rotation speed,6.5 kPa of negative pressure value,and 0.52%of missed seeding rate.The air-suction seed metering disc realized efficient and precise seed metering,and conformed to technical requirements of Cyperus esculentus seeding,providing a basis for selection of air-suction seed metering device of Cyperus esculentus seeder.
