摘　　要： 随着农村产业结构的变化,作物种植面积不断扩大,传统的施肥方式已不能实现肥量的精确控制,与之相应的耕种施肥技术需要提高和改进。近几年推广的精准农业技术,由于成本高和技术性强等原因还不能得到广泛应用。精准农业的推广急需一种简易、轻便、造价低廉、适合一般用户使用的变量施肥机械。为此,在已有施肥机的基础上,设计了与拖拉机配套使用的变量施肥机。 Along with the countryside development, the crops sown area expanded unceasingly, applied fertilizer the technology with it corresponding cultivation also to need to enhance with the improvement. This tradition applies fertilizer the way not to be able to realize the fat quantity accuracy control. In recent years, appeared the fine accurate agricultural technology, but because the cost is high, the technical nature strong and so on the reasons cannot obtain the widespread application, therefore urgently needs one kind simple, facile, the construction cost inexpensive and suits in the common user use variable applies fertilizer the machinery. Therefore we design the tractor necessary use variable fertilizer applicator.
