"Spring vies for the sun, summer for the time." At present, summer grain is mature in many places in China, and wheat has entered the harvest season. However, in the vast wheat fields, in the busy season of "three summers", only agricultural machinery is seen, but no one is seen. Even some large grain growers drive off-road vehicles, wear shoes, keep their feet free from mud and hands from touching water, subverting the traditional image of farmers who are "facing the Loess and facing the sky".

Today, the traditional "pickaxe, hoe, sickle and plough" is going to the museum, and the intelligent "Golden Horse" is on the main battlefield. With the continuous improvement of mechanization and intelligence level, the labor intensity has been greatly reduced, but the production efficiency and benefit have been greatly improved. The more stable and the better the "golden shoulder pole" of farmers is, behind this is the great change brought by agricultural science and technology to the mode of grain production.

It is easier for farmers to grow grain, and national food security is also more guaranteed. In recent years, the construction of high standard farmland, the application of Agricultural Internet of things, intelligent irrigation, unmanned aerial vehicle plant protection, unmanned intelligent rice transplanter, Beidou satellite navigation agricultural machinery and other hard core scientific and technological equipment gradually flew into ordinary people's homes, further consolidating the foundation of stable and high yield, greatly liberating the labor force, and improving the happiness of grain farmers. As one farmer said, in the past, it took more than a month to harvest with a small sickle. Now the high-powered harvester can finish all the farm work in a few days.

The key to promoting agricultural modernization lies in science and technology and talents. In recent years, a number of new professional farmers have emerged with brand-new images, which has changed the life style of Chinese farmers "working at sunrise and resting at sunset" for thousands of years. They have led the rapid growth of cooperatives, family farms and other main bodies, driven small farmers to share profits with new technologies, new services and new channels, accelerated the transformation of agricultural operation mode to scale, organization and specialization, provided strong talent support for the development of modern agriculture, constantly improved the comprehensive efficiency and competitiveness of agriculture, and made agriculture a leading industry and made farmers become a leading industry Attractive jobs make the countryside a beautiful home to live and work in peace and contentment. From the primitive agriculture of slash and burn cultivation, to the traditional agriculture of "relying on heaven", and then to the modern agriculture of improving quality and efficiency, agricultural science and technology has great potential and promising prospects.

At the same time, we must also realize that scientific and technological innovation is still a short board of agricultural production, and the promotion of some agricultural technologies is still in the "bonsai" stage, without forming a "landscape". Especially in some remote and backward areas, as well as hilly and mountainous areas with complex terrain, the scientific and technological content of agricultural production is relatively low. In addition, there are still some problems, such as the lack of domestic high-end agricultural machinery core technology, product quality needs to be improved. Therefore, it is necessary to speed up the cultivation of science and technology innovation enterprises, increase policy support for agricultural science and technology innovation projects, and let more and more "science and technology models" inject more vitality into China's transformation from a big agricultural country to a powerful agricultural country.
