To implement the strategy of rural revitalization, we must take ensuring the supply of important agricultural products, especially grain, as the primary task, give more prominence to improving the comprehensive agricultural production capacity, and truly implement the principle of "storing grain in the land and technology". We should continue to make efforts to promote the high-quality development of social security, weave a dense social security safety net, and provide support for the people's well-being. Food security is "the largest country". Everything is long, and eating is great. Food is the most important thing for the people. Through hard work, China has raised nearly one-fifth of the world's population with 9% of the world's arable land and 6% of the world's fresh water resources. From 400million people who did not have enough to eat at that time to more than 1.4 billion people who do well today, which has effectively answered the question of "who will feed China". This achievement has not come easily. We should continue to consolidate and expand it. On the issue of food security, we should not be careless at all. We should not think that the problem of food is dispensable when we enter industrialization, nor should we expect to rely on the international market to solve it. We should prepare for a rainy day, always tighten the string of food security, and always adhere to the principle of giving priority to ourselves, basing ourselves on China, ensuring production capacity, appropriate imports and scientific and technological support. Cultivated land is the lifeblood of grain production and the foundation of the sustainable development of the Chinese nation. Farmland is farmland, which can only be used to develop the planting industry, especially food production. We should implement the strictest farmland protection system, strengthen the use control, standardize the balance between occupation and compensation, strengthen the supervision of the use of land transfer, promote the use of abandoned land, and resolutely curb the "non-agricultural" of cultivated land and the "non grain" of basic farmland. Farmland must be good farmland. We should build a national food security industrial belt, strengthen the construction of farmland and water conservancy, implement black land protection projects, transform saline alkali land by classification, and strive to build 1billion mu of high standard farmland. We should take hard measures to "grow teeth" and comprehensively compact the responsibility of local Party committees and governments at all levels for protecting cultivated land. The central government should sign a "military order" for protecting cultivated land with all localities, strictly assess and pursue responsibility for life, and ensure that 1.8 billion mu of cultivated land is worthy of its name. The fundamental solution to the problem of eating lies in science and technology. The safety of seed sources is related to national security. We must make up our minds to develop China's seed industry and realize the self-reliance and self-reliance of seed industry science and technology and the self-control of seed sources. We should give full play to China's institutional advantages, scientifically allocate advantageous resources, promote the construction of major national innovation platforms in the seed industry, strengthen basic and cutting-edge research, strengthen the collection, protection, development and utilization of germplasm resources, and accelerate the industrialization of biological breeding. We should deepen the reform of the agricultural science and technology system, strengthen the dominant position of enterprises in innovation, improve the variety approval and intellectual property protection systems, and promote the high-quality development of China's seed industry by focusing on the construction of the innovation chain. —— (Xinhua News Agency)
