Xinhua News Agency, Beijing, March 24 (Reporter Yang Dingmiao, Wang Xuetao, Zhou Wenqi) After installing the battery, pouring in the herbicide, and gently pressing the operating handle, the farm staff made a skilled operation, and the unmanned plant protection machine took off in place and flew towards the wheat field. .

The "unmanned farm" in Zhaoqiao Township, Qiaocheng District, Bozhou City, Anhui Province ushered in the first spring ploughing season after its completion.

  Jiao Kui, the head of the farm, is an "old-fashioned" farmer. Seeing that one person is in charge of the operation and the other person is responsible for the loading, one drone can spray more than 1,500 acres of pesticides in one day.

He lamented that the efficiency of traditional labor has increased hundreds of times, and he couldn't help but admire his "new farmer" son Jiao Rui, because Jiao Rui is an expert in various information-based "new agricultural machinery".

  "As long as you have a mobile phone, you can turn on the automatic irrigation system to water at any time, no matter where you are." Jiao Rui said that in the farm office area, technicians remotely monitor the conditions of the wheat fields through the large electronic screen of the "farm brain", and can also monitor the conditions of the wheat fields in real time. Learn about field soil, air temperature and humidity.

  Moshang flowers are blooming in spring, and it is the best season for spring ploughing.

During this period, just like Jiao Kui's farm, villages all over China were busy with farming, spring ploughing, and spring management, and the fields were busy.

  Food is stable and the world is safe.

China's grain production has achieved 18 consecutive harvests, but the string of ensuring food security has never been relaxed.

In the past two years, affected by the combined effects of the epidemic and disasters, the Chinese have a deeper and more real understanding of the phrase "you have food in your hands and don't panic in your heart".

  "Filling the 'rice bag', filling the 'vegetable basket', and firmly holding the rice bowls of more than 1.4 billion Chinese people in their own hands" has become the consensus and direction of efforts of all parties in China.

  This year's National Two Sessions, representatives and committee members discussed how to protect arable land, revitalize the seed industry, mobilize enthusiasm for growing grain, increase scientific and technological support, and provide suggestions for "holding grain in the land and storing grain in technology".

  Grain output is maintained at more than 1.3 trillion catties, which is one of the main expected goals for this year's development proposed in the government work report.

"This is a 'military order' issued to us, and it is a hard task that must be completed." Tang Renjian, Minister of Agriculture and Rural Affairs, said at the first "Minister's Channel" of the two sessions this year.

  Hu Zucai, deputy director of China's National Development and Reform Commission, said during the two sessions that China should ensure the supply and price of grain, stabilize the sown area and output of rice and wheat, and maintain sufficient grain and stable prices.

  "'Storing grain in land and technology' is China's basic strategy to ensure comprehensive grain production capacity, and it is of great significance to ensure stable grain output," said Cheng Guoqiang, a professor at the School of Agriculture and Rural Development at Renmin University of China.

He emphasized that "storing grain in the land" not only means ensuring the area of ​​arable land, but also improving the quality of arable land.

  Located in Duntou Town, Haian, Nantong, on the east coast of China, the nearly 7,000 mu high-standard farmland project has entered the final stage of construction.

High-standard farmland with flat surface, rows of greenery, and matching irrigation and drainage facilities is an effective measure to improve the quality of cultivated land that is being promoted and popularized in China.

  "After completion, it will greatly improve the drainage and storage capacity of farmland, as well as the scale and mechanization level of grain production, and eradicate traditional flooding." Ding Jun, director of the Farmland Construction Management Division of Nantong Agriculture and Rural Bureau, said that "high standards" will be reflected in smart agriculture. , Tianmei countryside, high efficiency and water saving, etc.

  According to this year's government work report, China will strengthen the transformation of low- and medium-yielding fields, build 100 million mu of high-standard farmland, and build and transform a number of large and medium-sized irrigation areas.

  In the smart farm of Shanxi farmer Hu Tianni, sensors monitor the ground temperature, water content, fertility and other indicators in real time, realizing the integration of fixed sprinkler irrigation and water and fertilizer.

  "Now the ground temperature is low, flood irrigation may cause wheat not to grow seedlings, and also cause soil compaction. Sprinkler irrigation can not only keep the soil temperature unchanged, but also make the surface moist, which is conducive to seedling growth." He said.

  Affected by the flood disaster last autumn, Hu Tianni's 500 mu of wheat was planted more than 30 days later.

With the support of 9.9 million yuan from the central government, Ruicheng County, where he is located, has taken management and protection measures such as rolling and spraying on some wheat.

Scientific farming can increase the average yield of wheat by 300 catties. Hu Tianni is full of confidence in this year's harvest.

  To solve the problem of eating, the fundamental way out is technology.

In addition to the empowerment of agriculture through digitalization, the seed industry is the source of food security.

In Changsha, Hunan, where the late "Father of Hybrid Rice" Academician Yuan Longping lived and worked, the Yuelushan Laboratory started construction recently, and is committed to creating an innovation highland for the seed industry and promoting the high-quality development of China's seed industry.

  "It is necessary to strengthen the leading and supporting role of science and technology, and increase the innovation, promotion and application of new varieties, new technologies, and new products." Wang Juanling, vice president of Shanxi Agricultural University, believes that "storing grain in technology" means continuously increasing investment and improving innovation efficiency. , fully tap the yield potential of land, seeds and fertilizers, and use science and technology to "eat and squeeze" all aspects of agricultural production.

  Many places in China have issued guiding opinions and action plans for "holding grain in technology".

Jiangsu has started the construction of a full-scale mechanized demonstration county. It is expected that by the end of the "14th Five-Year Plan", the comprehensive mechanization level of crop cultivation and harvesting in the province will reach over 90%, and the overall mechanization level of characteristic agriculture will reach over 70%; The annual action plan will carry out six major actions, including improving the quality and efficiency of the planting and breeding industry, the construction of the entire agricultural industry chain, the green and circular development of agriculture, and the digital empowerment of agriculture.

  "Storing grain in technology" is also inseparable from supporting infrastructure and multi-departmental collaboration support.

Spring ploughing in some areas of Qimen, Anhui was once limited by low voltage and weak power in small hydropower supply areas. This year, the local distribution network construction and the transformation of Taiwan districts were implemented step by step, which greatly improved the power supply capacity; Shizong Town, Tongzhou District, Nantong City has more than 20,000 mu. High-standard farmland, in order to ensure the safe operation of more than 200 intelligent agricultural irrigation and pumping stations, the local power supply company has established a party member service team to provide all-weather "electric nanny" services.

  In China, "food security" is regarded as the "bigger of the country".

With a population of more than 1.4 billion, China feeds nearly one-fifth of the world's population with 9% of the world's arable land, making important contributions to world food security.

  Cheng Guoqiang believes that adhering to the strategic bottom line of basic self-sufficiency in grains and absolute security of rations, and the policy of "holding grain in the ground and in technology" will help stabilize China's grain output and achieve the expected goal.

  In 2021, China's total grain output will be 1,365.7 billion catties, and the annual grain output will reach a new high, remaining above 1.3 trillion catties for seven consecutive years.
