Xinhua News Agency, Lanzhou, May 4th, Title: The wheat waves accompany youth - the young "inventor" in the farmland

Xinhua News Agency reporter Cui Hanchao

In the years of youth, some defend the country and guard the border, some travel to the mountains and seas, and young people with ambition chase their dreams on different stages.

For 37-year-old Dai Fei, there is more than one stage of youth. He taught agricultural machinery knowledge on the podium, developed agricultural machinery equipment in the laboratory, and carried out field testing in the fields... A friend said that he was the "inventor" in the farmland.

Dai Fei is a professor at the School of Mechanical and Electrical Engineering of Gansu Agricultural University. He and his research team jointly developed the first domestic quash combine harvester, the first domestic hilly mountain quinoa combine harvester, and the self-propelled barley combined harvesting and baling machine with independent intellectual property rights... Since joining the work, the 12 agricultural machinery and equipment that Dai Fei participated in the research and development have been mass-produced and has been cultivated on the northwest land.

"My fathers work for farming, so I cannot live without land," said Dai Fei.

Dai Fei was born in Yuzhong County, Lanzhou City, Gansu Province. He grew up with the crops and always "lighted" whenever he saw a tractor. After joining the work, he realized that the research and development of agricultural machinery and equipment is not a closed-door construction in the laboratory, but a deep-dive into the fields and constantly polish and adjust the design parameters according to the specific use situation.

"In the research and development of agricultural machinery and equipment, the time in the fields accounts for 60% of the time. When harvesting crops, we have to follow the harvester to check with the sun, because the soil, humidity, crop density, etc. will affect the working conditions." Dai Fei said that for example, the flax that is widely planted in Gansu has a thicker stem. In the past, when harvesting artificial harvesting, we had to grind a sickle every time a mu was harvested, and ordinary harvesters were prone to entanglement. The development of stuff combine harvesters requires a lot of data to continuously improve product design.

Love in front of you, hard work is just an embellishment on the road to struggle. Dai Fei's research team has a total of 13 people, 11 of whom are young people born in the 1985s, who spread their youth in the fields and laboratories. "We, like everyone else, just want to do something for the motherland." Zhang Shilin, one of the research team members, said that the more difficult the production conditions are, the more agricultural machinery technology is needed, and the more people need to face the difficulties.

On the land of Longyuan, a group of young talents are making progress for the prosperity and strength of the motherland. The reporter learned from the Organization Department of the Gansu Provincial Party Committee that in recent years, Gansu has implemented the talent empowerment project in depth, promoted the introduction, training and use of talents in the same direction. Every year, more than 300 young talents are selected to be trained and trained at the front line of the industry, so as to achieve the same frequency resonance between talent growth and industrial upgrading, and contribute youth strength to the Chinese-style modernization process.

Dai Fei's hometown has long used the sturgeon combined harvester developed by him and his team. Now, Dai Fei mainly studies the "mechanism and mechanism of membrane soil-machine-crop interaction system in the arid areas of Northwest" and "key technologies and equipment for harvesting of small differences in Northwest mixed characteristic economic crops". He hopes that his research results can make the wheat waves in his hometown "one wave higher than the other wave".
