Performance of machinery in potato production in one growing season

摘要: Statistics on the machinery performance are essential for farm managers to make better decisions. In this paper, of all machineries in five sequential operations, namely bed forming, stone separation, planting, spraying and harvesting potato production system, were investigated during one growing season. order analyse decompose recorded GPS data into various time distance elements estimation performance, an automatic analysis tool was developed. The field efficiency capacity estimated each operation. Specifically, measured average 71.3% 68.5% 40.3% 69.7% spraying, 67.4% harvesting. capacities 1.46 ha/h, 0.53 0.47 10.21 0.51 respectively. These results deviate from corresponding estimations calculated based norm American Society Agricultural Biological Engineers (ASABE). deviations indicate that norms provided by ASABE cannot be used directly prediction work. Moreover, forming separation could as supplementary which does not provide these two operations. gained can help management operational decisions result potential improvement productivity profitability well environmental benefits.
