In the past, the "boring land" "rice granary" now -improvement and utilization of saline -alkali land in Jilin Province

Western Jilin Province has a large area of ​​saline -alkali land. There, black land and saline land are interspersed, like black and white patterns on the earth.

In July 2020, General Secretary Xi Jinping pointed out in Jilin that effective measures must be taken to protect the "giant panda in cultivated land" in black land; in October 2021, General Secretary Xi Jinping emphasized during the inspection in Shandong that the salt -alkali land was launched in Shandong. Comprehensive utilization is of great strategic significance for ensuring the safety of national grain and firm Chinese rice bowls.

In recent years, Jilin Province has thoroughly implemented the spirit of General Secretary Jinping's important instructions, launched the "Black Earth Grain" science and technology battle, promoted the comprehensive utilization of reserve resources such as saline -alkali land, and accelerated the improvement of food production capacity. It turned into "rice granary". The improvement and utilization of saline -alkali land is gradually becoming a new growth pole of grain production in Jilin Province.

"Land" transforms into a high standard farmland

Nenjiang, a beautiful curve flows in Da'an City, is like holding this vast plain in her arms. In midsummer, driving in the field of Da'an, outside the window, the scene under the blue sky and white clouds continuously switched: the saline -alkali land of white flowers, wetlands played by water birds, tabbed corn, green rice waves ...

Da'an City, Danle Town, Minle Village, villager Qu Weijie just returned from the rice field, and said with a smile on his face: "From the perspective of the growth of rice, the big harvest is just around the corner."

Former poor villagers villages were selected as a beautiful leisure village in China in 2021. Compared with the past, villagers' lives and villages have undergone tremendous changes. These changes originated from the land development and finishing project implemented in 2016.

There are more than a hundred acres of land in Qu Weijie's family, and the area is not large. However, due to the severe saline of the land, the land and the lack of land can be interspersed and distributed by the local people. At least half of this "land" is not output. The villagers in Minle Village have helpless pain in the heart of this piece of ugly "ringworm" on the land.

"At first, some villagers were unwilling to rectify the land. They did not believe that they could treat salt -alkali land." Qu Weijie said that the villagers had tried to improve salt -alkali land, but they failed. It is the arrival of the land development and finishing project, so that the villagers can see hope, and the good things that they dare not think about in the past have now become a fact in front of them.

The project will improve 15,000 acres of salt -alkali land into a paddy field, realizing the design, construction, improvement of that year, planting, planting, and harvest that year. The project has also implemented projects such as flat land, irrigation and drainage, field roads and farmland transmission and distribution, and build high -standard farmland.

"The previous' '“' has become a regular paddy field, which is suitable for large -scale farming. In addition to my own land, I have contracted more than 100 acres. In recent years, it has harvested every year. Now that they can earn about 250,000 yuan each year. "Qu Weijie said that the village collective will also publicize more than 7,000 acres of paddy fields through the government platform. Village environment.

The saline -alkali land in Da'an City, Jilin Province is improved to the direction of the paddy field

Minle Village is one of the successful cases of saline -alkali land in Jilin Province. The Jilin Provincial Party Committee and the Provincial Government attach great importance to the improvement of saline -alkali land, establish a strategy of land arrangement and saline -alkali land improvement in the province, and implement multiple engineering projects such as ecological water conservancy, western land arrangement, and rivers and lake connectivity. Essence Since Jilin's implementation of land rectification in 2000, the province has governed nearly 2.1 million mu of saline -alkali land. Since the "Thirteenth Five -Year Plan", Jilin Province has implemented 118 comprehensive saline and land comprehensive governance projects. 81.8%of the number of arable land.

Improved saline -alkali land helps ecological civilization

In the pilot project area of ​​the overall land comprehensive rectification of Da'an City, which is located in New Ping'an Town, the reporter of "China Natural Resources News" saw that the construction of the rice fields that had been completed was a dark green, the fish in the field of fields swimming, and there were birds flying over from time to time in the air. It seems to be an artificial wetland.

"In the past, in the past, except for a few drought fields distributed here, most of them were white and alkaline land of white flowers. The wind was blowing and the sky was full of sky and soil. The living conditions and living conditions are very poor. "Tang Haifeng, deputy director of the Da'an Natural Resources Bureau, introduced that today, the improvement of saline -alkali land is transformed from a single development and finishing model to a comprehensive governance of system repair.

The pilot project of the overall land rectification of Da'an City, according to the land resource endowment of the new Ping'an Town, has more than 100,000 acres of land in three villages in Ping'an Village, Changhe Village and Changming Village. Based on the principles of Yilin Zelin, Yicao, Yitian, Yitian, and wet wetness, coordinated planning and comprehensive governance. It plans to add 45,800 acres of cultivated land, 17,700 acres of dry fields, and 08,900 degenerative grasslands. Ura, 0.15 million mu of forest land.

On the water fields that are improved into saline -alkali land in Da'an City, Jilin Province, the rice grows in a good direction.

The project introduces drip irrigation salt to regulate saline -alkali agricultural agricultural and vegetation construction technology, and selects demonstrations for the development and afforestation test of the original soil -dry fields in heavy saline -alkali land. At present, the soil salt and pH value of the root layer of the project area have been greatly reduced. The corn of the test area that has been organized by organic fertilizers has grown well, and the planted willow tree survival rate reaches 98%. Not far, several high -rise residential buildings have been capped. Tang Haifeng introduced that it was a supporting and resettlement project and construction of the animal husbandry communities. 1042 villagers have been resettled. Baicheng and other places in western Jilin Province, located in the "East Asia -Australia West" channel in the world's eight major migratory birds. It is a post from large waterfowls such as white cranes and poultry in Siberia and Oceania. In the past, many migratory birds chose to go by bypassing the ecological environment due to saline of land. In recent years, Jilin Province has actively implemented the concept of Green Water and Qingshan. It has organized the improvement of saline -alkali land and ecological governance to promote the coordinated development of ecology and economy, and the harmonious coexistence of human and nature. The ecological environment of the western Jilin has continued to improve. Today, Baihe is back, and the Eastern White Burders and Wart Swans have also returned.

"Competition" of Tibetan Grain League

In Haiyu Township, Da'an City, the reporter saw a few large characters in the green rice fields of green oil: Jilin Daan's saline -alkali land govern the competition site. The staff responsible for controlling and guarding are busy in the field. It seems that this "science and technology competition" has entered the stage of heat.

Wang Changzhi, director of the Land Collection Center of the Da'an Natural Resources Bureau, introduced that over the years, many colleges, scientific research units and enterprises have carried out a demonstration demonstration of saline -alkali -to -alkali improvement tests in the Daan region, all of which have successful cases. The Jilin Provincial Department of Natural Resources has set up a demonstration base for the saline -alkali soil improvement test, introducing social capital investment and construction. It aims to build a "competition platform" for hiding grain to compare its own improvement techniques on the basic conditions. Article 22 Agricultural canal divides the project into 10 improved areas (9 water field improved areas, 1 dry field area). Nine companies are trying in different improved areas. Under the conditions where water conservancy and physical indicators tend to be consistent, compare the effect of increasing the production of 9 companies and scientific research teams under different fertilizers. Ecological repair advanced technology and scientific and technological achievements provide experience for the improvement of saline -alkali soil.

Trial planting began in March this year, and comprehensive planting was completed on June 15. Nine companies show their magical powers, for example: Huaqing Agriculture, a subsidiary of Tsinghua University, uses independent research and development to use desulfurization gypsum to improve salt -alkali land; China Science and Technology Bai Aogin Agricultural Development Co., Ltd. will "dilute the surface" creation and "cooked farming" Cultivation of the two into one; Beijing Zhongnongyufeng Ecological Technology Co., Ltd. has developed a comprehensive microorganistic technology to solve the problem of refractory saline -alkali in the process of saline -alkali and land governance. Establish technology quickly, and so on.

The reporter saw that in the experimental field of Huaqing Agriculture, the rice that was inserted for 40 days had grown to more than half meters high. Wang Changzhi introduced that the rice variety is Songliao No. 5, and now a plant has been divided into 30 plants. Each plant is estimated to produce 150 grains of rice. This year, the output per mu can reach 1100 catties.

A number of units perseveled in Jilin's perseverance to explore the governance technology and path of saline -alkali land, forming valuable governance experience. At the Ecological Test Station of the Da'an Alkali Land of the Chinese Academy of Sciences, the reporter saw Liang Zhengwei, a researcher who led the team here for nearly 20 years. Their scientific and technological achievements of the improvement of saline -alkali land won two second prizes for national science and technology progress.

The saline -alkali land in Da'an City, Jilin Province has now been improved into a green rice field.

"We lack anti -inverse varieties in the large -scale development process of soda saline -alkali land in Northeast Northeast, and make it difficult for water to grow rice such as rice. The new ideas and methods of heavy saline -alkali land quickly improved the new ideas and methods of physical chemistry synchronization and rapid improvement technology, developed key technologies of anti -inverse varieties supporting cultivation, and created the "Daan Mode" of the "Liangtian+Good By Carchen+Good Method" Trinity Salone Land efficient governance and use '. "Liang Zhengwei said that the implementation of the water drainage project in the western part of Jilin Province has enriched the water resources here, the comprehensive advantage of saline -alkali and land has obvious advantages, and the potential for saline -alkali cultivation can increase the potential.

Nowadays, more and more researchers who are dedicated to the improvement of saline -alkali land are written on this land down -to -earth, letting the black land rejuvenate.
