Spring is for the day, and summer for the time. " At present, the summer grain in many areas of China is mature and the wheat is in the harvest season. However, in the vast wheat field, in the busy season of "three summers", there are "only agricultural machinery but not people". Even some large grain growers drive off-road vehicles, wear leather shoes, do not mud their feet and touch water with their hands, which subverts the traditional image of farmers "facing the loess and facing the sky".

Nowadays, the traditional "pickaxe, hoe, sickle and plough" is going to the museum, and the intelligent "golden iron horse" is on the main battlefield. With the continuous improvement of mechanization and intelligence, the labor intensity has been greatly reduced, but the production efficiency and efficiency have been greatly improved. The "gold shoulder" of farmers has become more and more stable and better, which is behind the great changes brought by agricultural science and technology to the mode of grain production.

It is easier for farmers to grow food and more secure for the country's food security. In recent years, the construction of high standard farmland, the application of Agricultural Internet of things, intelligent irrigation, UAV plant protection, driverless intelligent transplanter, Beidou satellite navigation agricultural machinery and other hard core technology equipment have gradually flown into the homes of ordinary people, further consolidating the foundation of stable production and high yield, greatly liberating labor force, and improving the happiness of grain growers. As one farmer said, it used to take more than a month to harvest with a scythe. Now the high-powered harvester can finish all the agricultural work in a few days.

The key to promoting agricultural modernization lies in science and technology and talents. In recent years, a group of new professional farmers have emerged in a new image, which has changed the thousands of years of Chinese farmers' life style of "working at sunrise and resting at sunset". They have led the rapid growth of cooperatives, family farms and other main bodies, driven small farmers to share profits with new technologies, services and channels, accelerated the transformation of agricultural management 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, made agriculture a leading industry, and made farmers become Attractive occupations make the countryside a beautiful home for living and working in peace and contentment. From the primitive agriculture of slash and burn cultivation to the traditional agriculture of "relying on the nature to eat", to the modern agriculture of improving quality and efficiency, agricultural science and technology has great potential and great potential.

At the same time, we must also realize that scientific and technological innovation is still the short board of agricultural production, and some agricultural technology promotion still stays in the stage of "bonsai", without forming a "landscape". Especially in some remote and backward areas, as well as hills, mountains and other terrain complex areas, the scientific and technological content of agricultural production is relatively low. In addition, there are still some problems such as the lack of core technology of domestic high-end agricultural machinery and the improvement of product quality. 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 large agricultural country to an agricultural power.
