The trend of the times: high and new technology "playing with" traditional agriculture

If you want to ventilate the rice seedlings in the seedling shed, all you have to do is pick up your phone at home and press a few buttons to open the shutter door of the seedling shed, a high-tech segment in American Hollywood movies. Now it has been realized in the intelligent production of rice in Qixing Farm in Heilongjiang Reclamation area.

The farm uses global satellite positioning technology, remote sensing technology and geographic information technology to realize the quantification and accuracy of production management. Compared with the general field, the farmland of the Internet of things application demonstration park reduces the application of pesticides and chemical fertilizers by more than 10% per mu, and the per unit yield increases by 5% to 10%. " Liu Cheng, deputy director of Qixing Farm, said.

The Internet of things agriculture in Seven Star Farm is only a microcosm of China's high-tech "playing" with traditional agriculture. The 65 years since the founding of New China is not only the 65 years of rapid economic and social development, but also the 65 years of rapid development of agricultural science and technology and promoting the leapfrog development of agricultural production.

"65 years ago, the technical level of agricultural production and the level of per unit grain yield in China were very low, there was no infrastructure construction, the ability to resist natural disasters was very weak, a wide range of crops were harvested thinly, depended on nature for food, and there was a serious shortage of grain and other agricultural products. the phenomenon of begging is very serious in disaster years." Li Guoxiang, a researcher at the Chinese Academy of Social Sciences who has long been concerned about agricultural development, said.

Today, China's agriculture has already changed from the traditional farming mode of cattle ploughing and iron ploughing in the past to the intelligent agricultural production mode of "big machinery" and "big technology". Drone spraying pesticides, sprinkler irrigation, drip irrigation, water-saving irrigation, large harvester gallop fertile fields. Such a scene can be seen everywhere in many farmland in our country, and the current national comprehensive mechanization level is close to 60%.

In particular, it is worth mentioning that over the past 65 years, a number of major agricultural breeding and other scientific and technological achievements have been published one after another, which has become the "golden key" to solve the food problem-- the world leader in hybrid rice breeding. Hybrid corn, transgenic insect-resistant cotton, double-low rape and other successful research and development, selected lean pig hybrid combination, Chinese black and white dairy cattle and other excellent breeds.

It is under the promotion of agricultural high-tech that the Chinese people have gradually emerged from the memory shadow of lack of food and clothing and achieved a major leap forward of adequate food and clothing and good food and clothing.

Ms. Mou, a Beijing resident, recently bought selenium-rich black peanuts on a website. "I heard that these peanuts have the effect of protecting cardio-cerebral vessels and improving immunity, and my mother likes them very much," she told reporters. "

Ms Mou's mother has long remembered the old days of storing Chinese cabbage in winter. She said: "over the years, seeing that there are more kinds of food and all kinds of food, people no longer worry about eating."

Selenium-rich black peanuts, square watermelons, white eggplant, "weight" hundreds of jin of space pumpkins. In recent years, the research and development ability of dominant new varieties in China has been improved steadily. High and new technology has continuously improved the variety of agricultural products and enriched the dining tables of the common people, and the Chinese people have changed from being full to eating well.

From facing the loess back to the sky, to the mouse click easy irrigation, science and technology is a mirror, reflecting the changes of the times, recording the great achievements of agricultural development.

According to historical records, from 1949 to 2013, China's grain output increased from 113.18 million tons to 601.935 million tons, cotton output from 444000 tons to 6.3 million tons, and meat output from 2.21 million tons to 85 million tons. China's per capita share of grain has increased from less than 420 jin of raw grain in 1949 to more than 800 jin at present, exceeding the world average.

From breeding to cultivation, from planting to breeding, from production to circulation and consumption. Science and technology are adding soaring wings to traditional agriculture.
