Ding Zhaotang: the "doctor of tea" with science and technology
"People follow your heart and do what you like. If you don't have it now, keep looking and don't give up!" ——This is the motto of Professor Ding Zhaotang in the Tea Research Institute of horticultural college, and also a sentence he often teaches students.
Devoted to breeding, only for the promotion of northern tea
Qingdao Laoshan tea was introduced from the south to the north in the 1950s. However, due to the limitation of producing areas, the production and quality of Laoshan tea have always been the bottleneck restricting its industrialization development for more than half a century. The biggest problem faced by the introduction of tea from south to north is "cold". There are only two ways to solve this problem: keeping tea plants warm for winter in field management, or breeding high cold resistant varieties directly. But breeding is a time-consuming thing, and it may be spent more than ten years or decades without any achievements. Therefore, although there are many tea factories in Qingdao, they are not willing to make efforts to carry out breeding. Qingdao Tea planting The area is about 101000 mu. In 2010 alone, the output was reduced by 40% because of the severe cold. "If Qingdao tea wants to be bigger and stronger, variety is the key." Zhang Yuanfu, former vice mayor of Qingdao, said to Ding Zhaotang many times.
"If the government wants to do it and the enterprise doesn't, I will do it. Varieties are of great importance, not only affecting the "tea cup" of tea drinkers, but also the "money bags" of farmers. We must select good varieties suitable for the climate in Qingdao. " Ding Zhaotang used his spare time to travel all over the province's tea producing areas to collect tea varieties. On the basis of his original research and after several winter's systematic breeding, Ding Zhaotang finally bred a new high-quality cold resistant variety "Ruixue" - its extreme cold resistance temperature can reach - 13 ℃! In normal years, only a little protection is needed to survive the winter in the field. The breeding of "Ruixue" means that tea farmers in the north can finally stop worrying about the economic losses caused by freezing damage. Qingdao Evening News reported the varieties bred by Professor Ding Zhaotang in the front page headlines, and the Qingdao Municipal Science and Technology Bureau also released news on its official website.
Hard to protect seed and expand production
After the new varieties are bred, it is a difficult problem to preserve germplasm. Over the years, in order to develop clonal tea garden, most tea enterprises in our province have introduced tea seedlings from the south, which not only has poor adaptability and low survival rate, but also has high cost of long-distance transportation, which has caused a great burden to enterprises and tea farmers. Professor Ding Zhaotang, in his eyes and in his heart, is determined to lead everyone to explore a good clonal tea tree variety suitable for application in northern tea area Breeding technology system, a large number of high-quality cold resistant clone tea varieties. To this end, he used five years to design "double shed and one net tea tree cold resistant breeding device" and applied for utility model patent in accordance with the requirements of Qingdao Agricultural Committee and Qingdao science and Technology Bureau. He established the largest improved tea variety breeding base in Shandong Province in Qingdao ruicaoyuan tea science and technology Co., Ltd., and selected 5 varieties for seedling from more than 30 introduced clone varieties breed. How many new tea varieties have been introduced to Shandong Province through the large number of tea varieties and new varieties are being introduced to Shandong Province.
In terms of tea cultivation technology, Ding Zhaotang led the team to continuously innovate and study, and introduced the water and fertilizer integration technology suitable for Northern China. The technology not only solved the problems of less rainfall, dry climate, low utilization rate of water and fertilizer, and large labor input, but also greatly improved the water-soluble fertilizer formula formulated according to different varieties, seasons and growth periods The yield and quality of tea has become one of the main techniques to be popularized in Shandong Province in recent years. In terms of tea making technology, Ding Zhaotang promoted the clean, continuous and automatic processing technology of tea in ruicao garden of Qingdao, realizing the non landing production of tea, reducing the production cost of tea and the possibility of "secondary pollution" of tea.
"There is a great demand for clonal tea seedlings in Qingdao. The promotion of these new varieties will greatly improve the quality of Qingdao tea." In Ding Zhaotang's seedling base, seeing these precious tea seedlings, Zhao Zebin, then director of Qingdao Municipal Agricultural Committee, said happily. The on-the-spot meeting of ruicaoyuan fine tea garden, a one million mu fruit tea flower project in Qingdao, was held here. Jimo Municipal People's Congress (NPC) and CPPCC National Committee (CPPCC) organized NPC deputies and CPPCC members to visit ruicaoyuan tea base for investigation and study. The Tea Research Institute of Chinese Academy of Agricultural Sciences, Zhejiang University, Anhui Agricultural University, Fujian Academy of Agricultural Sciences, Yunnan Academy of Agricultural Sciences, Yunnan Agricultural University and scientific research institutions of universities in the province also organized relevant experts and professors to study in ruicaoyuan tea base. Relevant leaders of Qingdao Municipal Bureau of science and technology also visited the base for inspection and guidance.
Now, Ding Zhaotang has bred two new tea varieties with strong cold resistance, developed two environment-friendly fertilizers, proposed two tea tree special fertilizer formulations, applied for 19 national invention patents, and obtained 6 authorized patents. The largest tea germplasm resources nursery and the largest breeding base of improved tea varieties in Shandong Province were established. The rapid propagation technology system of "double shed and double film heat preservation and moisture preservation" suitable for application in northern tea area was established. Five cold resistant and asexual varieties suitable for large-scale popularization in Shandong Province were screened, and more than 2 million improved clones were popularized. Guided the industrial chain enterprises to create two famous and excellent teas, and won two science and technology progress awards of Jimo City and Qingdao city. The integrated system of water and fertilizer for tea garden production in North China was developed to realize the optimal management of water, fertilizer and nutrients. From the aspect of improving quality and increasing yield, it will bring more benefits to tea production in North China, and has important promotion value. These technical achievements have created huge economic and social benefits.
Devote oneself to education
As a university professor, Ding Zhaotang is not only busy with scientific research, but also responsible for educating students. Behind him, a large number of tea major college students and graduate students are thriving. In the eyes of tea majors, he is a humorous and passionate teacher.
Professor Ding has a set of methods to educate students. In the eyes of graduate students, he is a master, a coach and a kind father. Professor Ding loves reading. For decades, reading every morning and evening has become his unshakable living habit. His passion comes from these books. "Nine steps to success", "seven shortcuts ahead of time", "unconventional thinking", "Steve Jobs's magic speech" and "thinking to get rich" have been listed as the required reading materials for tea graduate students. He also held a variety of activities, such as "elevator lobbying", speech contest, so that graduate students can apply what they have learned. Ding Zhaotang said that each book he chose has a clear purpose, which is to provide impetus for graduate students' study and scientific research. It's boring to do experiments all the time. What should students do when they encounter difficulties and have no end? They may think of the persistence and perseverance of jobs' success in "the magic speech of jobs"; when they lack confidence, they will think of Napoleon? Hill's n steps to confidence building Under the guidance of Professor Ding, in his laboratory, "looking for differences" has become the core value concept of teachers and students. "The principle of time integration", "the most important thing always comes first", "the number 3 principle", "the 20 / 80 principle" have been applied by the students easily. Ding Zhaotang's graduate student Shi Hui said that her biggest achievement during her postgraduate study was the change of her thinking mode.
In Professor Ding's opinion, if you want to succeed, the most important thing is to change the way of thinking. You should not only learn the thinking mode of the successful person, but also implement it into daily behavior. As a graduate student, he has to sign in at 8:00 a.m. from Monday to Saturday, and will discuss the progress or design of the experiment every Monday morning. Some teachers and classmates said that his requirements on students were too strict. He said: "on the one hand, sign in can urge students to study. They are still children and need guidance. On the other hand, I need to make sure whether they are in school and what to do every day. I feel relieved to see them." His graduate student signed up for CET-4 and CET-6 invigilator. He felt very sorry after knowing that he had wasted a whole day. If he spent that day in reading literature, designing experiments and learning English, it would be more meaningful. For this reason, he specially wrote a short review and communicated with graduate students at the regular meeting on Monday. "It's easy to lead horses to the river, but it's hard to force them to drink water," he said. It's not difficult to let it go. There are a lot of people who are driven by inertia. It's hard to stick to what you think is right, but it's definitely worth it. " His father is as hopeful as his future teacher. At the same time, he is also a model for graduate students to learn. He infects them with his own actions.
Professor Ding Zhaotang led his team to engage in scientific research wholeheartedly. Behind the success, he paid countless hard work and sweat. Now just 50 years old, he is already full of silver hair, the whole person is very thin, the body is not as good as before. The doctor said that he used his brain too much and worked too hard. He should pay more attention to rest. He is now eating traditional Chinese medicine, while working, not a bit lax. He never gives himself a holiday, every day before 8 o'clock teacher Ding will arrive at the office on time. Mr. Ding has a book, which records the daily plan and summary. No matter where he goes, he will take it with him. He said that this habit has been adhered to for many years. In his drawer, there is a thick pile of such books, which are all his sweat over the years, which he regards as a treasure collection. Mr. Ding always has a lot of fantastic ideas in his mind. He can connect many seemingly unrelated things. He said that when he wakes up at night, if he suddenly thinks of something, he will immediately take out a book to write it down. Mr. Ding devoted himself to scientific research and never made up for it. His wife, Mr. Wang Yu, said that Mr. Ding is a very "critical" person. As long as he wants to do something, no matter how difficult it is, he will be content to be perfect. I think this is one of the important reasons why Mr. Ding can succeed.
A cup of tea, how many drops of sweat. Ding Zhaotang loves tea. He supports this vigorous subject with his white hair. From scientific research to teaching, he sowed, watered and harvested all the time.
