In the spring season, on an experimental field in the agricultural high-tech industry demonstration zone of the Yellow River Delta in Shandong Province, wheat has grown more than ten centimeters of new seedlings. Li Jianwei, the field business manager of Chuxin (Dongying) Modern Agriculture Co., Ltd., is guiding the workers to measure soil and mix fertilizers, looking forward to a good harvest in the new year. "Our company is planting 2000 acres of" Shiluan 02-1 "wheat on this experimental field, which has excellent cold and alkaline resistance." Li Jianwei squatted down and gently brushed away the soil at the roots of the tender seedlings, observing carefully. "Previously, the wheat yield here ranged from 700 to 800 kilograms per mu. Since last year, we have been screening and planting advantageous varieties, increasing the yield by more than 100 kilograms per mu. This year, the wheat seedlings have grown very well, and there is hope for increased yield." "Over the years, we have truly tasted the sweetness brought by seed technology. Now, we still have more than 10000 acres of land available to scientific research institutions. If they have any good scientific research results, they will cooperate with us as soon as possible to select higher quality varieties from them." Li Jianwei said. Dongying City is located in the core area of the Yellow River Delta, with a saline alkali land area of 3.418 million acres. The older generation of Dongying people have a saying: "It's even harder to plant a tree than to feed a child." Because the groundwater here is highly mineralized, the soil salinity is heavy, and it is greatly affected by tides, making it one of the most difficult delta type saline alkali lands to utilize in the world. Nowadays, seed technology is transforming the past "barren land" into a vibrant "new granary". At the digital breeding platform for salt alkali tolerant plants in the agricultural high-tech industry demonstration zone of the Yellow River Delta in Shandong Province, the reporter saw through a glass window that various crops such as soybeans and sorghum were thriving in an artificially simulated environment. Lin Shuang, an engineer from the Institute of Botany of the Chinese Academy of Sciences, told the reporter that this is the first digital breeding accelerator for salt tolerant plants in China. Plants with an outdoor growth cycle of 110 to 120 days can shorten their growth cycle to within 90 days in indoor platforms, allowing for faster exploration of the optimal growth environment for crops and accelerated iteration of plant breeding. In recent years, various breeding teams have collected and preserved 35000 salt tolerant germplasm resources in the Yellow River Delta Agricultural High tech Zone, screened and evaluated more than 7000 breeding materials, preliminarily selected 55 new strains, demonstrated and promoted more than 300000 acres, and increased efficiency by 15% to 20% per acre. Jia Xi, Assistant Director of the National Salt alkali Land Comprehensive Utilization Technology Innovation Center, said, "We have screened more than 120 crop varieties suitable for large-scale application on salt alkali land, and have successively created new high-yield records. Soybean yields 570 kilograms per mu, black wheat yields 900 kilograms per mu, and quinoa yields 380 kilograms per mu... In the modern agricultural experimental demonstration base of 12800 acres of salt alkali land in the agricultural high zone, each selected seed rewards the careful cultivation of scientific researchers and the hard work of farmers with a bountiful harvest.". Li Linbo, Deputy Director of the Planning and Development Department of the Salt alkali Land Comprehensive Utilization Service Center in the Yellow River Delta Agricultural High tech Zone, told reporters that in the past two years, the Agricultural High tech Zone has cooperated with 48 domestic agricultural universities and institutes, introduced 108 teams, and established an expert database of more than 1100 people; Developed 23 key core technologies and achieved 226 significant scientific and technological achievements. We focus on tackling the biological breeding, production capacity improvement, and ecological utilization of saline alkali land
