"What tree is this, what is the growth habit?" Many people have had such curiosity when looking at the surrounding trees. In order to let people know more about the science of trees, on May 15, Changzhou University students made a two-dimensional "identity card" for the trees on campus. Just swipe your phone and the “personal†information of the trees is clear. Two students from Changzhou University are hanging QR codes for trees. "I used to see a lot of trees in school, but I don't know what the name is. I always feel a little regret. Now these problems don't exist. We just need to scan the QR code to know all the information about this tree. "I saw the trees on the campus being tagged with the QR code," said Zhang Jian, a sophomore at the School of Petroleum Engineering at Changzhou University. After hanging the two-dimensional code "ID card" corresponding to the tree on the tree, just take out the mobile phone and scan it with the QR code to link to Baidu Encyclopedia, and then learn more detailed information of the tree, including morphological features. Growth habits, cultivation techniques and plant culture and other related information greatly enrich the information of trees. According to Changzhou University, they intend to carry out this activity throughout the city so that people can better understand the science knowledge about plants.
