In recent years, the situation of China's overall grain production remains stable, and the overall agricultural production has achieved a ninth consecutive year of growth, which ensures the national food security. At the same time, the arrangement of China's regional grain production has experienced significant changes. Among the overall grain production, the percentage of grain production in southern China has decreased, while the percentage of grain production in northern China, especially in the northeast Plain, has increased dramatically. Therefore, the new regional arrangement of grain production has been taking shape. In the future, we should make more effort to promote the grain production in the northeast area, and establish the northeast Plain as the national granary, which is an essential component to ensure food security. <<
