Solid granaries make the world safe. For a large country like ours with a population of 1.4 billion, the fundamental position of agriculture cannot be ignored and weakened at any time. It is true that we have food in our hands and we are not panicked at all times. Answer the question "Who will feed China" with ambition. We implemented the national food security strategy of "taking ourselves as the main force, basing ourselves on the domestic market, ensuring production capacity, appropriate imports, and supporting science and technology", put forward a new food security concept of "ensuring basic self-sufficiency of grain and absolute safety of grain rations", took a series of measures and successfully walked out of the path of characteristic food security, laying a solid foundation for ensuring food security on the new historical journey. Answer the question "Who will grow grain and how to grow grain" with backbone. "Who will plant grain and how to plant grain" is the key to determine whether our Chinese jobs can be firmly in their own hands. To build a food security system, we need to constantly promote and improve the agricultural modernization system, take the modern agricultural industrial system, production system, and management system as the starting point, accelerate agricultural modernization, and adhere to solving the problems of agriculture, rural areas, and farmers as the top priority. By consolidating and improving the basic rural management system, we will determine the property right protection of the land contractual management right, so that farmers can have a long-term "reassurance". At the same time, we will adhere to the principle of "policy guaranteed, business efficiency increased", adhere to and improve the minimum purchase price system, stabilize and strengthen the subsidy measures for grain farmers, and ensure and stimulate the enthusiasm of farmers to grow grain and the main production areas to pay attention to grain. Answer with confidence the question "on what to produce food". "What to rely on to produce food" is the basic condition for us Chinese to be able to fill our own rice bowls with Chinese food. To fully implement the spirit of the 20th National Congress of the Communist Party of China, we should stick to the red line of arable land to ensure food security, take hard measures to "grow teeth", constantly consolidate the "farming base" of the granaries of large countries, and protect the "giant panda in arable land", the black land. Seed is the "chip" of agriculture. To ensure food security, we must grasp the "chip" of seed. We should deeply implement the seed industry revitalization action, strengthen the protection, development and utilization of agricultural germplasm resources, give play to the seed "chip" function, and ensure that Chinese grain is mainly used in China; Meanwhile, improve relevant supervision
