Background:　To　study　the　application　of　the　mathematical　programming　method　in　agricultural　machinery　operation　optimal　allocation　and　scale　management,　this　paper　adopts　the　non-linear　programming　method　to　establish　the　relevant　mathematical　model.　Methodology:　This　paper　investigates　the　crop　planting　area,　mechanization　level,　and　agronomic　direction　requirements,　production　situation,　and　technological　process　of　corn　planting　mode.　Results:　The　structure　of　agricultural　machinery　equipment　is　relatively　reasonable,　and　the　production　efficiency　is　high.　In　the　whole　process　of　corn　production,　11.195　million　yuan　of　maize　production　value　was　optimized.　The　proper　harvest　time　of　corn　was　5　days,　the　planting　time　of　wheat　was　26　days,　and　the　harvest　time　of　wheat　was　10　days.　Conclusion:　The　optimal　allocation　quantity　of　agricultural　machinery　system　is　calculated　by　lingo　software,　and　the　mathematical　model　is　established　by　combining　non-linear　programming.　©　2021　Bentham　Science　Publishers.
