Li Jingrui shows the students the process of genetic experiments.
Zhang Yue took the children to do popular science experiments.
Students at Luojiashan Primary School in Wuhan City, Hubei Province, observe the growth of rice in a popular science class "Teacher, why is the rice you planted straight and ours floating away?Liu Lijun, an associate professor at Huazhong Agricultural University, turned on his mobile phone and looked at the ** taken in the field with the students of Luojiashan Primary School in Wuhan City, Hubei Province. He can't forget the scene in that science class, when the children couldn't wait to pull up their trouser legs and run into the mud pond. They were splashed with mud on their little faces, and they looked at the crooked rice with a bewildered expression.
The seedlings should be planted straight, and there is an inch into the mud field to be stable. Like the kids, keep your feet on the ground. Liu Lijun saw the value of agricultural science popularization in the eyes of the children.
Agricultural science popularization, let Langlang read and the sound of frogs in the fragrance of rice flowers, experts in the laboratory and farmers on the land, get into the mobile phone**, into the public eye. Nowadays, more and more agricultural scientists have joined the team of agricultural science popularization, and disseminated their insights to the public with real and simple field stories.
Experience science in the fragrance of rice flowers
In the first half of 2023, Liu Lijun has a thunderous "date" every Friday.
Just look at the equipment he brings: corn cobs, rulers, small hullers, boots, sickles, seeds of different colors in centrifuge tubes, ......The associate professor at the Agricultural University moved the popular science class to the experimental field on the campus and named the class "Seed Season".
When it is harvest time, the plump grains bend the ears of rice.
Liu Lijun grasped the stalk of rice with his left hand, held a curved sickle in his right hand, aimed the blade at the straw, and explained while demonstrating: "Note that rice harvest generally leaves 10-15 cm of stubble. As soon as the words fell, he cut hard, and a handful of rice was already in his hand. Two meters away, there was a cheer from the ridge of the field, and the children gathered around like birds in the field, vying to see the fruits of their labor.
Recalling such a scene, Liu Lijun feels that all the hard work is worth it. "People approach the land and experience the growth of crops through scientific practice, and can feel the vitality of life. ”
The popular science base is the main position for Zhang Yue to disseminate agricultural knowledge to primary and secondary school students. The technical cadre of the Institute of Agricultural Products Preservation and Processing Technology of the Tianjin Academy of Agricultural Sciences likes to take the children to experience it the most, because "such a link can mobilize everyone's enthusiasm more".
Anthocyanins that change color" is Zhang Yue's popular science "unique job". The children exclaimed as they watched the liquid gradually change from burgundy to deep blue. The magic of scientific experiments gave them a deep understanding of anthocyanins with high pH sensitivity.
In order to make popular science more interesting and experiments more attractive, Zhang Yue does a lot of work behind the scenes, in places that children are not aware of. A few days ago, Zhang Yue bought a large bag of grapes and brought them into the laboratory, and jingled them for several days, just to let the children experience making a margarita biscuit.
Kids will love the strange taste of grape juice and anthocyanins that will make them unforgettable. Zhang Yue said with a smile. For agricultural science popularization, they always do their best, often "tired", even if it is just a small part of their daily work.
Industry is brewing in the science and technology courtyard
Talking about the characteristics of agricultural science popularization, Li Jingrui, an associate professor at the College of Biology of China Agricultural University, believes that this work is "for everyone, especially farmers who are engaged in agricultural production on the front line".
In May 2023, Li Jingrui came to a rural village in a central province to conduct a corn genetic breeding experiment, but as soon as he was ready for the experiment, he and his team were "invited" out of the village by the villagers, because the local villagers thought that Li Jingrui was "doing some terrible biological experiment".
After several twists and turns, the matter was properly resolved, but this triggered Li Jingrui's thinking. Villagers who do not have knowledge of biology have all kinds of associations when they mention words like "gene" and "heredity". "I can't carry out scientific research without educating the villagers. Without scientific research results, there is no way to feed back production. Li Jingrui deeply felt the importance of opening up the "last mile" of agricultural science popularization.
Li Jingrui shared his heartAn ideal platform for farmers to popularize science - science and technology courtyard。Here, researchers can understand the needs of farmers, and farmers can learn about cutting-edge agricultural research. In his opinion, it takes time to popularize science for farmers, and a science and technology courtyard that "can't be moved" by the farmers' side will become an "outpost" for farmers' science popularization.
Zhang Yue also knows that science popularization for farmers is not an overnight achievement, so in addition to the science popularization base, she also often appears in the villages on the outskirts of Tianjin.
A popular science lecture on the theme of "processing methods of different types of agricultural products" was held in Ximafang Village, Dongmaquan Town, Wuqing District, Tianjin, and the villagers listened very carefully.
Ximafang Village has been planting melons for 100 years, but in recent years, due to the decline in market demand, the planting area of melons has shrunk from more than 1,000 acres to 40 acres. The villagers were anxious and hoped to find a way to do so at Zhang Yue's popular science lecture.
What kind of juice can we make from our melons?When talking about the suitable raw materials for non-concentrated reduced fruit juice (NFC), some villagers shouted excitedly.
Don't worry, let's take some melons back to do a processing adaptability evaluation. After testing, Zhang Yue found that the melon has a low sugar content but a high water content, which is suitable for the production of NFC juice and also meets the needs of people with diabetes.
"I've been growing melons all my life, and I never thought I could make juice!"The villagers of Ximafang Village have received good news from Zhang Yue, and they have more confidence in the establishment of the local melon industry.
Imagine popular science in the creative "brain hole".
Cultivate white and purple peas to trigger the side plot. Do you choose to continue with the pea hybridization experiment, or do you go to the spur?In Lee's class, a student is playing the role of Mendel, a geneticist. Li Jingrui hopes that through the plot and the way of acting, students can "re-walk" the scientific research path of their predecessors, feel the difficulties they faced at that time, and "feel the scientific spirit behind every piece of knowledge in the books".
Role-playing is one of the achievements of Li Jingrui's exploration of the content and form of popular science, and many agricultural science popularizers like him also realize that agricultural knowledge is an important part of popular science, and the scientific spirit and culture of agricultural science are also an indispensable part of agricultural popular science.
What costumes did ancient people wear?At a popular science lecture called "The Past and Present Life of Ramie" in Xianning, Hubei, Liu Lijun first threw out a question.
Hides!A farmer shouted, and laughter erupted from the otherwise silent venue.
Leaves!The venue suddenly became more lively.
Taking advantage of this enthusiasm, Liu Lijun talked about the hemp clothing of the ancients, the traces of hemp fabric on the Yangshao cultural pottery, and then the ramie cloth fragments in the Liangzhu cultural site. Everyone felt that in Xianning, the main hemp producing area, the daily work of hemp growers collided with the wisdom of the ancients, what a poetic thing!
The development of new technologies and new materials continues to impact this crop that has been used by human beings for thousands of years. The cultivation of hemp has a value that is more worth remembering than how to achieve economic benefits more quickly. How to pass on this ancient crop is the key proposition of Liu Lijun's agricultural science popularization.
Cultivation technology should be discussed, but if you want to fundamentally stimulate everyone's motivation for planting, let everyone fall in love with it, and feel the responsibility and charm of inheritance, I am afraid that there is only one way to go through culture. He said.
During the interview, Li Jingrui compared a gesture of opening his palms and said: "Open your mind." "Someone can create a theme playground based on the scene of the movie, and we can also make the molecular world into a science paradise!."Like many agricultural science popularizers, Li Jingrui loves to imagine the future of agricultural science popularization: animated films, video games, toy puzzles, ......The space of agricultural science popularization is being decorated with colorful colors by this group of young agricultural science popularizers.
