摘  要：
针对气吸滚筒式精量穴播器作业过程中能耗大、排种性能不稳定等问题,以主要影响因素:取种盘吸孔线速度和充种负压为研究对象进行正交试验、回归分析,确定各因素对排种性能的影响规律及较优工作参数组合。结果表明:充种相对压力-4.5kPa、取种盘吸孔线速度0.38m/s时为较优作业参数组合,此条件下穴播器的单粒指数为98.67%、综合评价指数为99.00%、重播指数为0.67%、漏播指数为0.67%,满足精量穴播要求。

摘  要：
In order to solve that the large energy consumption and unstable sowing-performance of air-suction cylindrical,orthogonal test and regression analysis were applied to research the relative pressure and suction-hole velocity that influenced the sowing-performance mainly. Variance analysis of the experiment results defined the influencing regularity and the optimization of the factors. Experimental results indicated that the sowing-performance became worse quickly with the increasing of suction-hole velocity,but became better with the increasing of relative pressure. The optimization of the two factors was the suction-hole velocity of 0.38m/s and the relative pressure of-4.5kPa. Under such working conditions,the single seed index was 98.67%,the synthetical rate of seed was 99.00%,the multiples index was 0.67%,and the miss index was 0.67%,so the seed-metering device could satisfy the demand for precision seeding.
