Abstract: Agricultural standardization is an important way to realize agricultural modernization. The improvement of grain production standardization in large grain production counties is beneficial to the quality improvement of grain products and the guarantee of national food security. Taking Tanghe County of Henan Province as a typical case, this paper analyzed the present situation of corn production standardization in large grain-producing counties represented by Tanghe County of Henan Province. The results showed that, compared with the standardized and non standardized production, the social benefit was remarkable, the cost and the output value were increased. The land cost was the key factor that restricted the economic benefit of standardization production and the enthusiasm of farmers. There were some problems in the production of corn production in big counties, such as the decline of economic profits, the lack of maize varieties, the low standardized production would of some farmers, the difficulty in transferring land and loans and less subsidies, and the limited agricultural input capacity of the government. The policy suggestions were put forward to strengthen the standardization of the whole industry chain, the ability of disaster warning, the ability of research and development of the seed industry, the extension of agricultural technology and information service, the support of the new agricultural management body and the transfer payment to the large agricultural county.
