Fan Xiaolin takes root in fertilizer piles and blooms in science and technology.

A few days ago, the research on controlled release coating technology in the key project of "New Fertilizer Creation", the first national agricultural science and technology support project in Guangdong, was supported by both national scientific research funds and supporting funds from enterprises. Professor Fan Xiaolin, director of Fertilizer and Balanced Fertilization Research Office of Huan Zi College of South China Agricultural University and doctoral supervisor, presided over the project. He has been rooted in the fertilizer pile for a long time, making the flowers of science and technology bloom in the spring of the era of innovation. Fan Xiaolin was born in an intellectual family and grew up in the city. Never having dealt with agriculture, he never thought that he would embark on the road of agricultural scientific research. Until June of 1982, Fan Xiaolin graduated from the Department of Soil Agricultural Chemistry of Northwest A&F University (formerly Northwest Agricultural University), and he still felt that agriculture was not his favorite.

Fan Xiaolin is a 77-year-old student after resuming the college entrance examination. Prior to this, Fan Xiaolin worked as a private teacher in a commune that jumped the queue in rural areas.

Fan Xiaolin said with a smile, "Although I applied for my favorite chemistry major at that time, I think there is more room for the development of chemistry major. However, at that time, the unified distribution of admission files could only obey the national arrangement and accepted this arrangement. " Although Fan Xiaolin was not very interested in soil agronomy at that time, he was strict with himself, mastered quite solid basic theory and professional knowledge, and his English was excellent, and he never fell into the top three in soil agronomy courses. Because of these, he laid a good foundation for his stay in school and future scientific research work. "I didn't want to do scientific research at that time, I just wanted to teach." Fan Xiaolin said that his experience of jumping the queue as a private teacher made him like the profession of teacher. He said that with students, I always feel young and full of energy, and it is a great happiness to share what I have learned. "This is also the reason why I chose to stay in school to teach."

From June 65438 to September 0985, a project named "Study on the Fixed Release and Bioavailability of Ammonium in the Internal Circulation of Nitrogen in Loess" made Fan Xiaolin have an indissoluble bond with fertilizer research. This is an international cooperation project of Zhongdeli Bigger University and a project of Shaanxi Provincial Science and Technology Commission and Agriculture Department.

At that time, Fan Xiaolin was already the academic research backbone of the Department of Soil Chemistry of Northwest Agricultural University (now Huan Zi College). Because of his high English level, he was selected as the main person in charge of the Chinese side to participate in the project research. The project lasted nearly 1 1 year,199665438+February, and the project was officially accepted. The following year, the project won the second prize of Shaanxi Science and Technology Progress Award. During this period, Fan Xiaolin also came step by step from assistant lecturer, lecturer, associate professor, vice president and deputy director of Plant Nutrition and Fertilizer Research Center.

"With the combination of workers and peasants, agriculture can also make a big difference." It was during the research of this project that Fan Xiaolin realized that the stage of agriculture was not small. "The stage is as big as the heart." So, while doing well in teaching, Fan Xiaolin began to apply for projects and engage in scientific research.

From 65438 to 0989, Fan Xiaolin applied for the first scientific research project-"Comprehensive Utilization of Pueraria lobata Cellulose and Development of Polymer Water Absorber". The project support fund is only 6000 yuan. "The project funds are only enough to buy necessary reagents, and it is impossible to buy instruments and equipment." Because there is no stirrer, Fan Xiaolin can only look at the reaction bottle and stir it regularly for 2 minutes every 5 minutes when developing polymer water absorbent. Fan Xiaolin Haoshi Duomo successfully synthesized Pueraria lobata cellulose water-absorbent (water-absorbent), but due to the limitation of funds, it could not be atomized and dried, and the water-absorbent ratio was only 800 times, but it was close to the water-retaining rate of starch water-absorbent, which could replace starch water-absorbent and save food. In the past ten years, Fan Xiaolin has successively hosted more than 20 national, provincial and ministerial level and international cooperative research projects, including 7 national natural science foundations, 3 international cooperative projects and national science and technology support programs 1, 1 863, 1 973 and 1 948.

"Luck is better." Fan Xiaolin said with a smile when answering the secret of the reporter's application for the project, "Combine theory with practice, find problems in production, then conduct targeted research, then feed back the scientific research results to production practice, test its feasibility in practice, and conduct further research and application according to the feedback results." Continuous and in-depth research is Fan Xiaolin's scientific research thought, so he has been persistently conducting multi-faceted and continuous research in his own research field for many years.

1September, 1997, in order to carry out more applied research and better solve the problems in agricultural production, Fan Xiaolin, who is expected to be promoted to the position of deputy director of the Department of Soil Chemistry of Northwest Agricultural University (now Institute of Resources and Environment), resolutely went south, stepped into the gate of South China Agricultural University and began his arduous research road of "tropical and subtropical plant nutrition" and "new fertilizer".

In response to a reporter's question, Fan Xiaolin explained, "In contrast, Guangdong has a strong applied research atmosphere, and scientific research results can be quickly transformed into productive forces." "The greatest pleasure of engaging in agricultural scientific research is to be able to serve farmers, rural areas and agriculture."

After entering South China Agricultural University, with the support of the school, Fan Xiaolin set up a laboratory of fertilizer and balanced fertilization, and personally took the lead. During this period, Fan Xiaolin took the lead in proposing that the development of controlled-release fertilizer with three characteristics, namely, the amount and speed of fertilizer supply are basically consistent with crop absorption, no pollution to the environment and low price, is an effective way to finally improve the nutrient utilization rate in China. In the field of fertilizer and balanced fertilization research, the idea of establishing a platform for the popularization and application of balanced fertilization principle and technology is put forward, including theoretical system, technical system and series compound fertilizer system.

In 2002, according to the research accumulation and precipitation of South China Agricultural University in the field of fertilizer and referring to the crystallization of predecessors and peers, he established, declared and was approved as the first doctoral program in fertilizer science in agricultural universities in China.

"The most gratifying thing is that my students and my team have successfully produced more than four series 100 controlled release fertilizer products by using the patented technology of controlled release fertilizer invention and the research and development achievements of controlled release fertilizer." It is reported that the manufacturing technology and research results of controlled release fertilizer invented by Fan Xiaolin have cooperated with Sanyuan Preite Controlled Release Fertilizer Co., Ltd., which has reached the level of large-scale industrialization. Among them, the manufacturing technology of heterogeneous variable-speed controlled release fertilizer has reached the international advanced level, and its series of special compound fertilizer production processes and technologies have also been adopted by China-Arab Fertilizer Co., Ltd.

Heaven rewards diligence. Hard sweat moistens the field of his scientific research and urges the seeds of science and technology in the eleventh five-year plan. It is believed that under the leadership of Professor Fan Xiaolin, his team will shine brilliantly in the field of "Research on Controlled Release Coating Technology" and write a brilliant chapter for the development of China's fertilizer industry.
