Come to increase production as the core

Contribute to the realization of agricultural modernization

At the forum, Academician Li Jiayang failed to reach the scene for reporting because of the epidemic. Researcher Yu Hong, a member of the team of Academician Li Jiayang, brought the latest research results of the team, that is, how to improve the output of rice while dealing with salt coercion.

According to the study of academician Li Jiayang, salt coercion is one of the main non -biological stress that restrict plant production and crop yield. The total global salt soil area is as high as 800 million hectares. If it can be used for grain production, it will make important contributions to ensuring food safety. Therefore It is of great significance to continuously improve the salt resistance of rice. On the basis of improving the salt resistance of rice, Li Jiayang led the team to focus on improving the yield of rice, cloned a key gene to increase rice production, and further analyzed the molecular mechanism of the coordinated regulation of rice output and anti -inverse traits. The efficient and accurate molecular design and breeding system provides effective strategies for solving the problem of mutual restraint of rice output and quality.

From the experimental field to the laboratory, Li Jiayang and the team have been farming in the field for decades to escort the food security in my country. They have published more than 210 papers in international mainstream academic journals. The research results with international influence have been selected for the top ten progress in China or the top ten scientific and technological progress of China.

The cultivation of high -quality and high -quality rice varieties is the direction of Li Jiayang and the team. Researcher Yu Hong said that the latest research results, the main effect of rice plant type regulation, have been widely used in the cultivation of excellent rice varieties, and are expected to be further used in the improvement of rice varieties of saline -alkali land.

Develop grass animal husbandry

Help saline -alkali real estate capacity improvement

The people use food as the sky, but the food itself is constantly changing. In recent years, there have been fewer and fewer rice on the table of Chinese people, but more and more vegetables, meat and egg milk, etc. have become more and more. The changes in food structure are also affecting the structure of food production. For researchers, they also change their research direction.

"The demand for meat protein has improved, and the demand for forage and feed will also go up. The main pressure of grain safety is concentrated in the safety of feed grain. For many years, my country's feed needs to be imported in large quantities. Food safety issues. "On the forum, Academician Cao Xiaofeng shared her research results with the participants. After the improved Tian Jing, it was not only suitable for planting in saline and alkali land, but also had a significant repair effect on the soil. grass.

According to Academician Cao Xiaofeng, the planting of Tianjing saves one third of the land and two -thirds of the planting time than other pastoral grass, and it can be renewed after cutting. For cattle and sheep feed. It is worth mentioning that planting fields can reduce the salt in the soil layer, and can adapt well for salt -alkali, waterlogging, and barren land. At present, the Tian Jing planted by Cao Xiaofeng's team has reached 420 acres in our city, of which 50 acres of Guofeng Farm in Chenzhuang Town, Lijin, 200 acres of Huanghekou Town, Kenli District, and 170 acres of national agricultural high districts in the Yellow River Delta. The sheep in Wo Zhen had already eaten the local self -produced Tian Jing.

"Tian Jing can be used as a model plant to conduct anti -inverse strategy research, and it can also develop a new type of beancoplasty with both feed feed, which has a very broad application prospect." Academician Cao Xiaofeng said that after the forum closes Planting base inspection and cultivation.

The use of Chinese rice bowls to strengthen the use of rice and saline -alkali land

During the forum, Academician Chen Wenfu made a keynote report on "Planting Rice and Salviac Land and the Protection of Black Land". In the report, he proposed that food security is the "big of the country", and its basis is cultivated land, water resources and seeds. At present, the most important focus of the country is the revitalization of industry, the protection of black land, and the development and utilization of saline -alkali land. In this context, when the forum coincides with, "the development and use of saline -alkali land is a glorious and arduous task of our agricultural science and technology workers."

According to Academician Chen Wenfu, in terms of improvement and utilization of coastal saline -alkali land, Liaoning has established a special research institution since 1958. It is engaged in the improvement and utilization research of coastal saline -alkali land, which is a leading position in the world. The total area of ​​saline and alkali land in my country is about 1.5 billion mu, and rice is one of the most important rations of the people of our country. According to his research, the dynamic law of salt and salt in the five major domestic areas is: salt comes with water, salt goes with water, water goes with the gas, and the salt is gone. In addition to the improvement of rice planting and saline land, in addition to engineering measures, it is more important to synchronize the cultivation of salt -resistant varieties and saline -alkali rice planting technology. Among them, the selection of salt -tolerant varieties is important. It is necessary to take salt tolerance and high -quality high quality as the fundamental goal. When it comes to the comprehensive utilization and development of Dongying saline -alkali land, Academician Chen Wenfu stated that Dongying is located in the semi -wet saline area of ​​the coastal coast, and there are many similarities between the saline -alkali land and Liaoning. Earlier, he was invited to participate in the newly selected salt -japan rice product "Salt, yellow incense and japonica" selected by the China Science and Technology East Camp Molecular Design Breeding Research Center for real production and quality analysis. The average yield per mu, the appearance quality has reached the standard of first -class rice. This variety is sown in the sand with salt content of six thousandths of thousands of thousands of salt in the modern agricultural demonstration area of ​​Dongying City. It only irrigates fresh water during the seedling and dumping period. In other times, micro -salt water irrigations are used. The advantages of strong aroma and slender grain type. Academician Chen Wenfu believes that the "salt and yellow fragrant japan" successfully tried on the 6 ‰ saline -alkali land, which achieved high -yield, high -quality, anti -inverse coordination and unity, and improved the use of micro -salted water -type rice for coastal saline -alkali land to achieve grain production and ecology. The balanced development of the environment provides a feasible way.

Collect the quality resources of anti -salt -alkali crops

Fight the "turning in the industry"

In this forum, affected by the epidemic, Academician Qian Qian shared his recent research results with the experts of the meeting through online ways. "Crop quality resources are precious strategic resources, and there are no autonomous varieties without autonomous germplasm resources." Academicians who have been engaged in the study of national agricultural species quality libraries believe that seeds are "chips" of agriculture, and they are the entire agriculture. The foundation is the foundation of promoting the stable development of agricultural for a long time and ensuring the security of national food. Choosing the variety of salt -tolerant crops and the development of saline -alkali land seeds is the top priority to ensure the safety of national food.

Academician Qian Qian said that since 1956, my country carried out the census and collection operations of farm -based quality resources. The total amount of germs of the national germs of crops exceeded 520,000, and the preservation volume ranked second in the world. Through the development, sharing, and utilization of high -quality resource on -site display, high -quality resources, to promote the original innovation of agricultural science and technology, provide breakthrough materials for breeding, cultivate excellent varieties, support the development of characteristic agricultural industries, and fight the "turning battle of the seed industry" Essence

Academician Qian Qian had previously came to Dongying for research. He said that the Chinese Academy of Sciences has planned the Shandong Base of the Seed Innovation Research Institute and the China Science and Camp Molecule Design Breeding Research Center in advance with strategic vision. Appraisal and protection, the interpretation of salt resistance, the selection of salt tolerance varieties, and salt -alkali land cultivation technology, etc., provide solutions and models for the high -quality green development of the saline -alkali area, and serve the construction of the Yellow River Delta efficient ecological economic zone. At present, the Seed Innovation Research Institute of the Chinese Academy of Sciences has conducted extensive screening of genetic resources. It has selected 18 salt -resistant resources from more than 8,000 soybeans, and 14 salt -resistant resources were selected from more than 10,000 rice. At present, important progress has been made in the crops such as salt beans, rice, peanuts, pupae, and sweet sorghum.

Help saline -alkali land development and utilization

"This forum has gathered many high -level experts in related fields, and it is also a good combination of academic activities and research demonstration work of saline -alkali land species. The selection of excellent saline -tolerant varieties, in order to promote the application of saline and alkali real estate to enhance the application of new theories, new technologies and achievements, and promote the high -quality development of saline -alkali agricultural agricultural development. Academician Yang Weicai said.

In 2018, at the Dongying Modern Agricultural Demonstration Zone, the Institute of Genetics and Development Biology of the Chinese Academy of Sciences and the Dongying Municipal People's Government jointly established the Zhongke Dongying Molecular Design Breeding Research Center. Since then, Academician Yang Weicai has paid close attention to the development and utilization of Dongying saline and alkali land. According to him, the Institute of Genetics and Development Biology of the Chinese Academy of Sciences currently has a fine variety demonstration area of ​​1,500 acres of slices in Dongying, including small oats, sorghum, rice and soybeans. This is the modern agriculture in Dongying City in the past five years. A centralized display of the excellent varieties selected in the demonstration area. "During this forum, we will invite the guests to the guests to the city's modern agricultural demonstration area to inspect on the spot to investigate the growth of excellent saline -resistant varieties cultivated by the Chinese Academy of Sciences on the spot."

According to Academician Yang Weicai, there are many advantages in the research on the development of saline -alkali land in Dongying, which greatly enriches the type of scientific research. Dongying salt -alkali land is mainly new salt land, and there are many types. effect. In order to further construct the agricultural paradigm of salt -alkali land and serve the national food safety and high -quality development strategy of the Yellow River Basin, the China Science and Technology Dongying Molecular Design and Breeding Research Center established the Yellow River Delta saline land agricultural test station in the Dongying Modern Agricultural Demonstration Zone this year. Important scientific research platforms using and salt -resistant crops are also the base for the Chinese Academy of Sciences to carry out experimental work in the Dongying area. At present, more than 20 research teams including Li Zhensheng, Li Jiayang, Cao Xiaofeng and other academicians including Li Zhensheng, Li Jiayang, and Cao Xiaofeng rely on the test stations to carry out salt -alkali land scientific research work to reveal the meta -resistant molecular mechanism of crops, edit crop salt -resistant genes, and selected salt -resistant crops Variety and development of saline -alkali land use technology. "The test station demonstrates the plant varieties of our own intellectual property rights, involving 7 plants such as soybeans, corn, rice, sorghum, fields, long spikes, and 稷 子."

Filter salt -resistant grass protection food safety

Grain safety is the "big of the country". Among them, forage is an important part of food safety. Cultivating saline -alkali forage crops and making full use of saline -alkali land to increase the supply of forage is essential to ensure food safety.

Academician Kang believes that the current research and breeding level of forage in my country is significantly behind the main grain crops, and the upgrade is slow. According to national policies, the non -arable land forage industry such as salin -alkali land is an important development direction, and the key to development lies in the scientific and technological innovation of breeding.

In the forum, Academician Ji Kang introduced his latest research results to everyone. According to reports, his team has used the concept and science and technology system for the design and breeding of main grain crop modules such as rice and other main grain crop modules. Quality screening and design have been selected for a number of new products such as sweet sorghum and 苜蓿, and have built salt -resistant forage screening and planting test platforms in our city. The town and others have created a scientific and technological innovation platform for saline -alkali grass animal husbandry. At present, the third -level breeding system of the National Agricultural High Zone of the Yellow River Delta has been established, and the selection of 3,000 acres of salt gradient forage breeding bases with Abang Agricultural cooperation has also been completed and put into operation.

"At present, the industrialization of breeding technology is slow, and we will continue to promote the transformation of advanced breeding technologies in the next step, orderly promote the industrialization of breeding in an orderly manner, and achieve self -improvement of my country's seed industry technology." Guankang said in the forum.

In the report, Ji Kang also further listed a number of major representative of major scientific research progress. Among them, the "tuber breeding to seed planting" technology for the first time applied the genome design concept to potato breeding, which brought revolutionary changes to the potato planting model, and the tuber changed the tuber. Breeding is seed planting, which is expected to save millions of acres of potato breeding land for the country each year.
