[forge ahead into a new journey, make contributions to a new era and great changes] have the courage to make breakthroughs and strive to achieve high-level scientific and technological self-reliance
CCTV news (News Network): Xi Jinping General Secretary pointed out that the basic point of the Chinese nation’s struggle is self-reliance, and the only way to climb the world’s scientific and technological peak is independent innovation. Since the 18th CPC National Congress, under the strong leadership of the CPC Central Committee with Comrade Xi Jinping as the core, China has taken self-reliance and self-improvement in science and technology as the strategic support for national development, made continuous breakthroughs in the fields of basic science and cutting-edge technology, and embarked on a path of independent innovation with Chinese characteristics.
On Haizi mountain, Daocheng, Sichuan, at an altitude of 4410 meters, the world’s largest and most sensitive “gaohaiba cosmic ray observatory” is conducting a new round of scientific observation. Its core component, namely the photomultiplier tube, which can make the observation equipment more “hearing and seeing”, has been fully localized. For Chinese scientists, the independent production of this core device was only a bold idea a decade ago.
Basic research is the source of scientific and technological innovation, but it can not be achieved overnight. A small general component of high-energy physics experiment, photomultiplier tube, has become a key point in urgent need of independent innovation. In 2013, Xi Jinping general secretary came to the Chinese Academy of Sciences for investigation. At the Institute of high energy physics of the Chinese Academy of Sciences, he proposed that we must set up ambition and catch up with each other to promote the accelerated development of China’s science and technology. This sentence is a great encouragement to the team of the Institute of high energy physics. In order to solve the core technical problems in large-scale scientific research devices as soon as possible, the Institute of high energy physics accelerated its research and development. After countless experiments, it finally developed a photomultiplier tube with the world’s advanced level.
In 2020, after a long period of exploration and joint research, 15000 domestic 20 inch photomultiplier tubes will be produced and ready for use in China’s second generation neutrino experiment – Jiangmen neutrino experiment. This alone will save hundreds of millions of yuan compared with purchasing foreign equipment. “The key core technology is not to come, buy or beg, so we must take the road of independent innovation.” Since the 18th CPC National Congress, Chinese scientific and technological workers have made continuous innovations and breakthroughs in basic research and core key technologies. The localization rate of the core components of the fighter, which has set China’s deepest manned deep diving record, has exceeded 96.5%, and has made cutting-edge breakthroughs in materials, acoustics and other fields. The global networking of Beidou satellite navigation system has been completed, and the core components have been 100% localized. Jin Kui, a “post-80s” scientist of the Chinese Academy of Sciences, spent nearly six years leading his team to produce the world’s most cutting-edge material gene experimental equipment, revealing a 10-year unsolved quantitative physical law of high temperature superconductivity.
The improvement of independent innovation ability of core technology also depends on the increase of national investment. Since the 18th CPC National Congress, China’s R & D investment in the whole society has increased from 1024 billion yuan in 2012 to 2790 billion yuan in 2021, of which the investment in basic research has increased from 49.8 billion yuan to more than 160 billion yuan, 3.4 times that of a decade ago. The number of large scientific installations put into operation and under construction in China has increased from a handful to more than 50, and the ability to make breakthroughs in basic research and strategic frontiers has been greatly improved, laying a new foundation for great change and building a dream power.
Li Keqiang inspected the Ministry of agriculture and rural areas and presided over the symposium
CCTV news (news broadcast): on the 23rd, Li Keqiang, member of the Standing Committee of the Political Bureau of the CPC Central Committee and Premier of the State Council, visited the Ministry of agriculture and rural areas and presided over a symposium.
At the agricultural information office, Li Keqiang listened to the reports of spring management and spring ploughing. He was very concerned about the situation of wheat seedlings delayed by last year’s autumn flood. He learned that the proportion of class I and II seedlings was significantly higher than that before winter. Li Keqiang told him to continue accurate guidance and service. He said that the agricultural situation is connected with the grain situation, the grain situation is connected with the people’s situation, and the people depend on food. We should continue to strengthen monitoring, timely reflect the situation and suggestions, and promote stable agricultural production and increase production.
At the meeting, the Ministry of agriculture and rural areas made a report, and the main heads of Hebei, Heilongjiang and Henan provincial governments made a video speech. Li Keqiang said that agriculture is the foundation of the national economy. In recent years, under the strong leadership of the Party Central Committee with Comrade Xi Jinping as the core, and with the joint efforts of all parties, remarkable achievements have been made in agricultural and rural development and bumper grain harvests have been achieved year after year. At present, the international situation is complex and grim, and unstable factors such as sharp price increases and Shenzhen Agricultural Products Group Co.Ltd(000061) market fluctuations are increasing. China’s development and agricultural production are facing new challenges. China’s grain and important Shenzhen Agricultural Products Group Co.Ltd(000061) stocks are sufficient and the supply is guaranteed, but we should always tighten the string of ensuring food security based on ourselves and deal with external uncertainty with the certainty of stable production and supply in China, which is very important to stabilize prices and stabilize the overall situation of economic and social development. We should implement the decisions and arrangements of the Party Central Committee and the State Council, implement the new development concept, promote high-quality development, coordinate epidemic prevention and control and economic and social development, pay close attention to agricultural production, promote reform, ensure the “rice bag” and “vegetable basket” of more than 1.4 billion people, and consolidate the foundation for sustained and healthy economic and social development.
Li Keqiang said that farmers do not wait. At present, there is still room to improve the seedling situation in the main wheat producing areas in the north. We should promote the transformation of weak seedlings into strong ones through scientific topdressing, and strengthen the follow-up field management to ensure a good summer harvest. We will pay close attention to spring ploughing and preparation, implement the spring sowing area, and ensure that the grain output this year remains above 1.3 trillion kg. All parties should focus on the overall situation and give strong support to agricultural production. In view of the rising prices of chemical fertilizers, pesticides and diesel oil, support enterprises to increase production and supply from the aspects of tax reduction and fee reduction, raw material supply and energy consumption, and ensure the transportation and distribution of agricultural materials. Special support measures should be specially studied for special varieties, so as to tap potential, increase production and expand diversified imports, and do a good job in reserve regulation with market-oriented methods. The state has issued another 20 billion yuan of agricultural subsidies to farmers who actually grow grain, which should be paid in place as soon as possible.
Li Keqiang said that China still has a long way to go to realize modernization, and that the registered residence population in rural areas still has 760 million, so we must continue to promote agricultural modernization. We will consolidate and expand the achievements in poverty alleviation and solidly promote rural revitalization. Respect the wishes of farmers and develop various forms of moderate scale operation according to local conditions. Firmly hold the red line of 1.8 billion mu of cultivated land, promote the construction of farmland water conservancy facilities and high standard farmland, speed up the tackling, popularization and application of improved varieties and advanced agricultural machinery and equipment, and improve the comprehensive agricultural production capacity.
Hu Chunhua, Xiao Jie and he Lifeng attended.
in the first two months of this year, the logistics operation started smoothly
China Central Television network news (news broadcast): the data released by China Federation of logistics and procurement today (March 24) show that from January to February this year, China’s logistics operation was generally stable and the total amount of social logistics increased rapidly. From January to February this year, the total amount of social logistics in China was 51.8 trillion yuan, with a year-on-year increase of 7.2%. The growth rate of total logistics continued to pick up, and was significantly higher than that in 2019 before the epidemic.
From the perspective of structure, the policy effect of expanding domestic demand and promoting consumption continued to appear, and the demand for industry, consumption and logistics maintained rapid growth. From January to February, the total logistics volume of industrial products increased by 7.5% year-on-year, 1.4 percentage points faster than the average growth rate of the two years from 2020 to 2021. The logistics demand of consumer goods manufacturing industry increased by 9.7% year-on-year, 5.2 percentage points faster than the average growth rate of 20202021. In addition, the demand for import logistics continues to fall, but the decline is narrowing, and the role of logistics in promoting the stable operation of industrial chain and supply chain continues to be prominent.
NASA released the latest Mars image
China Central Television network news (news broadcast): the National Space Administration today (March 24) released the high-resolution images of the inspection area recently taken by the tianwen-1 orbiter, as well as the latest Mars images such as self photos taken by the zhurong Rover.
This is a 0.5-meter resolution image of the inspection area of the “zhurong” Mars rover, which was taken by the “tianwen-1” orbiter when it passed over the inspection area of the Mars rover a few days ago. In the picture, the driving route of the “zhurong” is clearly identifiable.
The “zhurong” Rover also sent back self photos from the surface of Mars. Compared with the photos taken when it just landed, it can be seen that a thin layer of sand and dust has accumulated on the surface of the rover. At present, no obvious dust weather has been observed in the inspection area of “zhurong”. Judging from the telemetry information, the power generation efficiency of the solar wing is affected to some extent, but the energy is still sufficient.
This is the sandstorm activity in the high latitudes of the northern hemisphere of Mars captured by the medium resolution camera of tianwen-1 orbiter. The engineering team found that since late January this year, there has been obvious wind sand activity in the area north of 60 ° north latitude of Mars. It can be seen from the figure that local sandstorms occurred in this area in February this year, and typical features are covered by a large amount of sand and dust, which is difficult to distinguish.
So far, the “zhurong” Mars rover has worked on the surface of Mars for 306 Martian days, traveling a total of 1784 meters. The tianwen-1 orbiter has been in orbit for 609 days and is 277 million kilometers away from the earth. At present, the two filters are operating normally.
