This　article　discusses　the　partition　node　incremental　deployment　method　in　the　wireless　sensor　network,　which　is　divided　into　partition　structure　deployment,　incremental　deployment　nodes　and　node　position　adjustment.　It　suggests　how　the　partition　node　incremental　deployment　method　might　influence　the　running　of　the　farmland　wireless　sensor　networks,　and　gives　illustration　of　how　the　connective　and　stable　communication　were　provided　against　the　instability　of　the　farmland　wireless　sensor　networks.
