"Seeds are the key to China's food security. Only by holding Chinese seeds tightly with your own hands can you stabilize China's rice bowl and achieve food security." Why does the general secretary care about a small seed? "A seed can change a world, and a technology can create a miracle." As early as the central rural work conference in December 2013, this sentence of the general secretary revealed the true meaning. —— In December 2020, the central economic work conference proposed to solve the problems of seeds and cultivated land. At the central rural work conference in the same year, the general secretary emphasized the early realization of independent and controllable seed sources of important agricultural products; —— In May 2021, during the inspection in Henan, it was pointed out that we should start from cultivating good seeds, strengthen the tackling of key problems in improved seed technology, and rely on Chinese seeds to ensure China's food security; —— In July 2021, when presiding over the 20th meeting of the central deep reform commission, he stressed that "we should raise seed source security to a strategic height related to national security, and concentrate on solving problems, making up weaknesses, strengthening advantages and controlling risks"; —— In October 2021, during the investigation and investigation in the agricultural high-tech industry demonstration zone in the Yellow River Delta, it was emphasized to change the breeding concept from controlling saline alkali land to adapting crops to breeding saline alkali tolerant plants to adapt to saline alkali land; —— …… From changing breeding concept to ensuring food security, from promoting platform construction to biological breeding industrialization... Behind the repeated mention by the general secretary, there are major considerations at the overall level. A seed, connected with the "big country", is related to the initiative of food security. More than one billion people have to eat, which is the biggest national condition of our country. In recent years, China's grain yield has increased significantly, more than 50% of which is due to variety improvement. An inventory of China's seed family can be found that the planting area of varieties independently selected by China's crops accounts for more than 95%, which has achieved the goal of "China's grain mainly uses Chinese varieties". At the same time, China's soybean and maize are affected by breeding, cultivation and other factors. Now the unit yield is only about 60% of that of the United States. "Farmers say, 'good children and good mothers, good planting and more grain', 'if you don't choose to plant the land, you're tired and empty'." Seeds are the "chip" of agriculture. Seed is the key to produce more and better grain on limited cultivated land. A seed carries the hope of securing China's rice bowl. At present and in the future, the pattern of tight balance between grain supply and demand in China has not changed. In the future, grain demand will continue to increase, and the tight balance between supply and demand will become tighter and tighter. In addition, the international situation is complex and grim, and the string of ensuring food security should always be very tight. A seed, connected with the key to creating miracles, is related to building a strong country in science and technology. "To solve the problem of eating, the fundamental way out lies in science and technology." This time in Hainan, the general secretary focused on understanding the innovation of seed industry. He stressed that seed sources should be self-contained and controllable, and seed industry science and technology should be self-reliance and self-improvement. This is a major event of strategic significance. Independent innovation is the key to a successful turnaround in the seed industry. When he first arrived at liangjiahe, during the period when he was sent to the seed production station to study improved seed breeding, he actively studied breeding knowledge, took notes with a small notebook, returned to the cave and told everyone about seed production when he had the opportunity. "As a large agricultural country, we must not lag behind. We must adhere to the self-reliance and self-improvement of agricultural science and technology and accelerate the tackling of key core agricultural technologies." A seed, connected with agricultural modernization, is related to the good life of the people. Seed industry is at the source of the whole agricultural industrial chain and is a landmark and pilot project for the construction of modern agriculture. The 20th meeting of the Central Committee for comprehensively deepening reform, held in July 2021, deliberated and adopted the action plan for the revitalization of the seed industry, which provides a road map and mission statement for promoting China's progress from a large seed industry to a powerful seed industry. Hundreds of millions of farmers are moving towards comprehensive modernization at the same time, which can release a huge amount of consumption and investment demand. Promoting the revitalization of seed industry is the necessity of drawing a new picture of Rural Revitalization. We are moving towards the second Centennial goal. We should start from better meeting the people's needs for a better life and ensure the effective supply of grain and other kinds of food. Rice bags and vegetable baskets should be carried well, and variety is the key. We should further promote the structural reform of the agricultural supply side, and promote the cultivation of excellent varieties, quality improvement, brand building and standardized production. Firmly fighting the turnaround of the seed industry is undoubtedly an important foundation for realizing agricultural modernization and meeting the needs of people's better life. However, the revitalization of the seed industry is by no means overnight. As the general secretary stressed during his inspection tour in Hainan: "grind a sword in ten years, take credit for a long time, and do a good job in this major event." (Xinhua News Agency)
