In tradition, worker must computer, then change the gear for regulating the quantity of seeding by himself. This system can regulate it automatically by a microcomputer inside after inputting the demand of seeding quantity, and the regulating precision improved.
此系统与传统播种机人工计算、更换齿轮调整播量的方法不同，而是利用单片机可编程的优点，在播种前输入播量、排种器类型及五轮仪打滑移率等参数，系统内部会自动进行计算调整，提高了调节精度。
