The rapid development of modern information technology makes the amount of every day data increase at the speed of TB, how to effectively use and manage the big data with explosive growth? It is a problem need to be solved urgently. Big data has penetrated into various fields including agriculture, with the agricultural informatization construction and the application of Internet technology in agricultural production, resulting in a large amount of agricultural data to be stored, managed and processed. Based on the background of the construction of agricultural informatization in Pengzhou Gexian mountain agricultural demonstration base of Chengdu agricultural science and technology vocational college, according to the demand of informatization construction of agriculture, we build high performance agricultural big data management platform based on Hadoop, realizing the agricultural big data safe and reliable storage, intelligent management and application. And ultimately we achieve the purpose of early intelligent warning of agricultural production, intelligent decision-making and intelligent analysis, providing professional guidance to farmers. This lays the foundation for China to enter the intelligent agricultural era based on fine planting, precise control, visual management and intelligent decision-making.
