Not long ago, in a cow house in Lingwu Modern Breeding Base in Yinchuan, Ningxia, the first batch of improved dairy cows produced by live egg collection in vitro embryos in Ningxia were successively born. "This is the first time in China to successfully build a laboratory in a breeding farm, collect eggs in vivo - produce embryos in vitro in an efficient and batch way without affecting the normal breeding plan, and equip improved dairy cows with 'China Core'." Jin Yaping, chief expert of the dairy seed industry innovation team of Northwest Agriculture and Forestry University and chief expert of Ningxia Lingwu Dairy Science and Technology Academy, said. As early as last April, Lingwu City cooperated with the Northwest University of Agriculture and Forestry Science and Technology to carry out the demonstration project of the reserve cow breeding base. More than 30 experts jointly tackled key problems, which not only achieved technological breakthrough and application transformation, but also achieved "spillover effect" in the local talent cultivation - Lingwu Vocational and Technical School opened the livestock and poultry production technology specialty. Nowadays, Yinchuan is paying more attention to talents than ever before. "In recent years, we began to break the ice from the top-level design, and successively introduced a package of talent policies. We built a talent policy system of" 1+N+X "that accurately supports the X rules of industrial development, including one general rule of" 30 rules for talents to revitalize the city in Yinchuan ", and N supporting special rules such as scientific and technological innovation. We vigorously implemented the four major projects of talent introduction, training, warmth and vitality. The total number of various types of talents in the city reached 436800, and the" wild goose array "of talents drove high-quality development Gradually form a 'matrix'. " Zhang Jing, director of the Talent Work Bureau of Yinchuan Municipal Party Committee, said. Tailor the work to the needs of the industry, and Yinchuan is thirsty for talents. However, the facts have proved that the practice of spreading a big net to attract talents and blindly pursuing "high talents" and "foreign talents" has resulted in the waste and secondary loss of human resources. How to build new advantages of talent introduction and education in underdeveloped areas? "Focusing on the" three new "industrial layout and the construction of" two capitals and five bases ", we have tailored ourselves, focusing on the introduction of highly skilled talents and the introduction and cultivation of outstanding young talents and practical talents, actively promoting the deep integration of the talent chain, the industrial chain and the innovation chain, and releasing the" intellectual power "of talents to the greatest extent." Introduction by relevant person in charge of Yinchuan Municipal Human Resources Bureau. Helan County of Yinchuan City is a famous aquaculture county in the northwest, but the water quality problems during the aquaculture period have long plagued the aquaculture enterprises. In the past two years, Duan Yunling, a professor in the School of Civil Engineering and Water Conservancy of Tsinghua University, and his team have overcome this problem. "We use the microbial nitrogen removal process to manage the water quality of Penaeus vannamei cultured in the greenhouse. Now we do not need to change the water for two crops a year, but only need to supplement the evaporation water and a small amount of water for harmless treatment of waste solids." Duan Yunling said that the yield of South American white prawns raised in hothouses here per mu has reached more than 1000 kilograms, and it is planned to raise three times next year. In recent years, through the establishment of "high-quality development think tank" and other ways, Yinchuan Municipal Human Resources Bureau has successively introduced more than 5000 high-level urgently needed talents, more than 200 talent teams, organized and implemented more than 300 various talent cooperation projects, and constantly strengthened "internal strength" through "external intelligence". Xia Mingxu, Dean of School of Materials and New Energy of Ningxia University and Dean of Materials Research Institute of Shanghai Jiaotong University (Yinchuan), is a member of Yinchuan High Quality Development Expert Think Tank. Since 2017, he has led the research institute to provide more than 4000 enterprises
