CCTV News:This year, China has fully implemented a new round of 100 billion Jin of grain production capacity improvement action. In Heilongjiang Province, while stabilizing the sown area of grain, 74 high-quality and efficient production technology models were integrated and promoted by crops and varieties, which greatly increased the yield per unit area.

At Zhaoguang Farm in the Great Northern Wilderness, the reporter saw that three high-powered locomotives were working together, and the sowing of 2500 mu of land could be completed in one day.

Zhaoguang Farm, which has 520,000 mu of arable land, mainly focuses on dry farming. This year, during the large-scale B/L production in the local area, the double-row cultivation mode with big ridges was mainly promoted, which not only can preserve water and soil moisture, increase ground temperature, but also can keep a reasonable spacing and maximize the use of light to promote crop growth.

In the farmland of Longjiang county, with the movement of the seeder, the drip irrigation belt, seeds and fertilizer behind it were buried on the ridge platform with a width of 120 cm.

This technology promoted by Longjiang County this year is an integrated planting technology of water and fertilizer with large ridges and double rows of shallow buried drip irrigation, which effectively solves the problem of inconvenient field management after increasing the planting density of soybeans and corn.

As early as this spring ploughing, Heilongjiang Province compiled the "List of Five Good Policies for Increasing Large-area Yield", and made overall plans for national and provincial-level related project funds to create policies such as large-ridge close planting scale main body award, superior planting and superior machine compensation, so as to fully ensure that the yield increase will be effective.

"Getian transformation" helps to increase production and income

Grain production in Heilongjiang has been bumper for 20 years in a row. How to continue to improve grain production capacity? The reporter learned in the interview that "Getian transformation" is one of the important ways. The so-called grid field transformation is mainly aimed at the transformation and upgrading of low-lying land and small plots of grid field, so that low-yield fields can be upgraded to high-yield fields and "small ponds" can be turned into "large grid fields". In this way, under the condition of the same water surface area, the reduction of pond ridges can increase the effective planting area and make agricultural machinery operation more convenient.

These days, Qixing Farm in the Great Northern Wilderness ushered in the transplanting season, and the grower Liu Hongfu planted 400 mu of rice this year. Although there are all kinds of machinery at home, in the past, the size and shape of paddy fields were irregular, and the locomotive operation could not be put to good use, which became a heart disease for Liu.

Because each paddy field has small ponds and many ridges, it not only occupies a lot of area, but also affects the operation effect and soil preparation efficiency of supporting machinery. In the past two years, under the guidance of experts, Liu Hongfu has gradually transformed the farmland. After eliminating ridges and expanding ponds and leveling the land, the fragmented plots have become large squares, and farming has changed the world immediately.

Up to now, Beidahuang has implemented more than 19 million mu of large-scale paddy field transformation, accounting for 87% of the paddy field area. This year, it plans to complete another 2.8 million mu of transformation tasks to help large-scale bill of lading production.

In Hulin City, after the transformation of 2,000 mu of irregular paddy field in a local cooperative, large-scale agricultural machinery completely replaced labor, which accelerated the transplanting of rice seedlings this year.

Small squares were transformed into large fields, and the effective cultivated area was added. This year, Heilongjiang will add 14 million mu of high-standard farmland, and many places are implementing a new modern high-standard farmland planning model of "all the way through the middle, fields on both sides, and canals around", reducing the occupation of agricultural roads and improving the utilization rate of cultivated land.

　　This year’s government work report mentioned that "after careful preparation, we successfully held a simple, safe and wonderful Beijing Winter Olympics, and we will certainly be able to run the newly opened Winter Paralympics". At the same time, the report puts forward that "the legacy of Beijing Winter Olympics should be used well". So what is the Olympic legacy?

　　According to the definition given by the International Olympic Committee, the Olympic legacy is the result of realizing the Olympic vision, including all tangible and intangible long-term benefits created or accelerated by hosting the Olympic Games for the public, urban and regional development and the Olympic movement. On the eve of the opening of the Beijing Winter Olympics, the Beijing Organizing Committee for the Winter Olympics released the Heritage Report Collection of the Beijing 2022 Winter Olympics and Paralympic Games (2022), which covers seven aspects, including sports, economy, society, culture, environment, urban and regional development. During the Beijing Winter Olympics, 44 typical heritage cases in these seven aspects were also published, summarizing the highlights of the popularization and development of ice and snow sports, winter Olympic venues, scientific and technological innovation, urban renewal, regional cooperation, volunteer service and many other aspects.

　　What are the highlights of Beijing’s Winter Olympics legacy? What does it have to do with ordinary people?

　　Member of Chinese People’s Political Consultative Conference Lian YumingThe Beijing Winter Olympics has left a rich Olympic legacy for China. My personal summary is that the six legacies of the Olympic Games light up the city of the Olympic Games, including sports events, competitive level, venues and facilities, talent teams, etc., which is the most direct legacy of the Winter Olympics. Through the Olympic Games as a world stage, more Chinese has realized the importance of ice and snow sports to public health and leisure industry, and more Chinese has realized through the Winter Olympics that it is a happy and healthy popular sport to participate in ice and snow sports. I think this has taken a new step to popularize the ice and snow industry, especially for healthy China and a sports power.

　　Professor Sun Baoli of Beijing Sport University"Olympic legacy" is the tangible and intangible long-term benefits brought by hosting the Olympic Games to people, cities or regions and the Olympic movement. In the "post-Olympic" period, further improving the level of public services and solving the people’s livelihood problems with the help of the Beijing Winter Olympics legacy is the main way to bring benefits and gain to the people, and it is also an important embodiment of the direct connection between the Beijing Winter Olympics legacy and ordinary people. The venues and facilities of the Winter Olympics are the tangible heritage of the Beijing Winter Olympics. After the games, they can provide the people with a national fitness venue continuously, so that more people can participate in the ice and snow sports, thus promoting the popularization and development of ice and snow sports in China, and further improving the sports public service level of the city. The intangible heritage of Beijing Winter Olympics also includes the cultural value of the Olympic movement and the collective memory of the public for the Winter Olympics. For example, the Beijing Winter Olympics embodies the common aspiration and pursuit of all mankind for peace and unity, advocates the concept of "community of human destiny", and shows the image of China and the spirit of China.

　　How to use the Beijing Winter Olympic Stadium with the most beautiful Chinese style after the game?

　　Sports heritage can be said to be one of the most direct and important heritages of Beijing Winter Olympics. Among them, the beautiful Winter Olympics venues and their nicknames full of Chinese romance left a deep impression on everyone. "Snow Youlong" dances with "Ice Ribbon" and "Snow Ruyi" holds hands with "Ice Yuhuan". These winter Olympic venues not only show the concept of "green, shared, open and clean", but also spread the elegant and romantic beauty of China to the world through the Winter Olympics.

　　Chinese People’s Political Consultative Conference member Shen JinTake the national ski jumping center "Xueruyi" as an example, we have considered the post-competition utilization of the venue from the beginning of design. Besides competitions, we have done many other functions, such as the "Snow Ruyi" Summit Club, which is about 3,000 square meters of open space without columns. It can be used for forums, exhibitions and even catering. "Snow Flying" is also the platform of Shougang. The site selection combined with the transformation of industrial remains has built a sports theme park to directly serve the ice and snow sports. At the same time, it promoted the green transformation and upgrading of Shougang.

　　In addition to what Shen Jin mentioned, the "water cube" of the Beijing 2008 Olympic Games turned into an "ice cube" in the Winter Olympics is a typical case of recycling after the games.

　　As a "Double Olympics" venue, the "Ice Cube" is the largest curling venue in the history of the Winter Olympics, and it is also the only "Double Olympics" venue in the world to set up a curling track on the swimming pool. After the Winter Olympics, the National Aquatics Center will become a comprehensive platform for ice events, mass ice fitness and curling promotion. According to reports, in the future, the venues will be freely converted between water and ice, starting as an ice rink in November each year and returning to a swimming pool around April the following year, which reflects the high-quality development of architecture and technology and keeps the "Double Olympics" heritage shining.

　　In addition to the Winter Olympics venues, Tu Xiaodong, director of the Propaganda Department of the State Sports General Administration, said that driving 300 million people to participate in ice and snow sports is the most important legacy of the Beijing Winter Olympics. According to the data of the National Bureau of Statistics, from the successful bid for the Beijing Winter Olympics to October 2021, the number of people who participated in ice and snow sports in China reached 346 million, and the participation rate of ice and snow sports was 24.56%. Snow and ice are in full bloom in China.
