Design and Research on Variable-Rate Fertilization Computer Control System

Abstract:

Based on domestic and foreign research situations of variable-rate fertilizing technology, the overall structure and working mechanism of variable-rate fertilizing machine were described, control content and strategy of control system were studied, AT89C5 SCM was used as a core control element in control system, control system hardware and software were designed and integrated. Variable-rate fertilizing experiments in space and paddy field showed that working efficiency of the spreader was up to 6 hm2/h, fertilizing error was less than 5%, fertilizing stability variation coefficient was less than 6.2%, working performance and control system design of the fertilizer can satisfy the demand of variable-rate fertilization in paddy field.
