摘　　要：针对当前国内农业生产的发展情况,介绍了一种适合国内粮食产区推广使用的变量施肥控制器。该变量施肥控制器结合我国目前国产的施肥设备均采用普通外槽轮作为施肥机肥料计量装置的特点,控制系统通过调整外槽轮的转动速度达到调整肥料量的目的。利用该控制系统可以在土壤肥力不一致的情况下,用预先划分地块不同施肥量的方法,通过驾驶员在行驶过程中自动调整施肥量指示按钮,达到精准变量施肥的目的。同时,对控制器电子结构及软件设计进行了详细的介绍,对系统使用不同肥料进行了控制性能试验和检测。In this paper, aiming at the current development of domestic agricultural production, introduced a variable fertilizer controller which suits for a domestic food - producing areas to promote output. The variable rate fertilization controller combined with the current Chinese made fertilizer equipment, mechanism of metering system for the applicator uses a flute wheel. The amount of fertilizer is determined by the rotation speed of flute wheel. The use of the control system can be inconsistent in soil fertility, pre - division of plots with different fertilizer way through the process of moving the driver automatically adjusts the amount of fertilizer direction buttons to precision variable fertilization. Papers on the electronic structure of the controller and software design in detail, using a different system for the control of fertilizer test and testing.
