摘　　要：针对小麦精播技术节省种子、减少田间间苗定苗用工、提高农作物产量与品质、减少制种用田等优点,利用气吸式精密排种器的工作原理,进行小麦精密排种器的参数优化设计;研究吸孔直径、风机压力和排种盘转速对播种性能的影响,并确定因素的取值范围;采用均匀试验设计的方法安排试验,建立排种合格指数的回归方程;分析各因素对排种性能指标的影响规律,进行参数优化,对模型寻优得出最优参数组合。试验证明:最优组合好于其他组合,满足了小麦精密播种的要求。The wheat precision seed metering device was optimization designed, using the principle of air - suction precision seed metering. The main influence factors, bore diameter, vacuum, rotate speed of pahe, was studied to determine the scope of factor. Uniform design experimentation was adopted to establish regression equation of qualified index. The effect relation of three factors was find out to qualified index, and parameters were optimized to seek the optimum parameters combination. Through experimentation test, optimum parameters combination surpasses other combinations, and has satisfied the request of wheat precision seeding.
