摘　　要：移栽是烟叶生产的关键工序之一,而影响烟草移栽的主要因素是移栽的烟苗疏密不一。为了解决这一问题,我们利用AT89s51系列单片机对烟草移栽机的机械投苗系统进行了改造。该系统通过传感器把烟苗的株距的数值反馈给控制系统,再通过执行来进行投苗。我们通过实验数据分析可以看出,该系统的株距都平均在500mm左右,株距均匀统一,符合农民要求,因此使用该系统不仅提高了移栽的稳定,而且提高了烟苗前期的育苗质量。Transplanting is the key process of tobacco production.And the varying space between seedlings is the bottleneck of tobacco transplanting.This paper improves the seedling delivery system via MCU（AT89s51）.The plant spacing data is fed back to a control system by sensors,and the spacing is adjusted to a set value based on the data.The experimental data shows that the average plant spacing is 500mm,and this also shows that the improved seedling delivery system can meet requirements of tobacco farmers.The system not only enhances the stability of tobacco transplanting,but also improves the quality of previous grow seedlings.
