With　the　rapid　development　of　the　social　economy　and　the　continuous　improvement　of　people＇s　quality　of　life,　under　the　background　of　promoting　＇Internet　+＇　modern　agriculture,　the　safety　of　agricultural　products　has　aroused　widespread　concern　in　society,　and　further　promoted　the　research　of　traceability　technology　of　reliable　and　credible　agricultural　products.　This　paper　proposes　a　method　that　apply　the　Internet　of　Things　and　blockchain　technology　to　agricultural　traceability　scenarios.　The　method　uses　agricultural　sensors　to　detect　product　production　environment　parameters,　improve　production　efficiency,　and　uses　blockchain　technology　combined　with　asymmetric　passwords　to　provide　security　for　the　Internet　of　Things.　Blockchain　technology　makes　data　irreversible　and　traceable,　which　enables　the　traceability　of　agricultural　products　to　be　realized.　This　paper　also　proposes　a　fusion　method　of　blockchain　technology　and　intelligent　technology.　It　uses　machine　learning　methods　to　analyze　the　production　and　sales　data　on　the　chain,　helping　producers　and　enterprises　to　improve　efficiency　and　solve　practical　problems.　©　2019　IEEE.
