Maize is the most important crop in Heilongjiang province.Heilongjiang is facing with severe situation of the compressed maize area.In order to explore the development direction of maize production in Heilongjiang,based on the analysis of panel data and experimental data,this paper summarized the recent production situation,climate change characteristic and its influence on the production of maize,and the influence of economic policies on the maize production in Heilongjiang.The results showed that the increase of total yield of maize in Heilongjiang was mainly caused by the increase of planting area,and the main reason for the enlargement of the area was the expansion of social demand and the support of government policy.The contribution of maize yield increase was relatively small,and the technical factors that affected the yield increase from high to low were close planting,fertilization and variety improvement.At the same time,the effect of climate change on maize production had more advantages than disadvantages.The strategic of maize production in Heilongjiang in the future should limit the planted area by providing fallow subsidies,promote no tillage cultivation methods,implement of maize straw,maintain balance between land use and fertilizer,plant early maturity,high yield,high density,lodging resistance,and suitable for grain harvest of varieties,reasonable planting density and precision fertilization,improve the yield and reduce the cost,comprehensive improve land productivity and the utilization rate of maize production resources,reduce the cost per unit of grain,and improve the competitiveness of maize.
