If you look down on the salt lake from the air, the squares are arranged into several small pools, presenting a colorful and beautiful scene, like nature's palette, which is the origin of the "colorful salt lake".

Behind this "colorful salt lake", countless people who love salt lakes have paid silent attention to the long-term protection and silent payment of salt lake environment, water quality, water sources, algae, birds, plants, etc. If the "Colorful Salt Lake" is likened to "Nature's Palette", then these people are the "colorists" of the "Colorful Salt Lake". Among these "colorists", there is a scientific researcher named Ding Hongxia, who injects magical "magic" into the "Colorful Salt Lake" through the power of science. Today, let's walk into the research room of Ding Hongxia, a researcher at the Technology Center of Nanfeng Chemical Group Co., Ltd., and learn about her "colorful scientific research" together.

In 1995, Ding Hongxia, who had just graduated from school, had her first job, engaged in the development and research of daily chemical products in the former Yuncheng Salinization Bureau. From the initial research and development of daily chemical products, to the later research and development of salt lake health tourism specialty products, and then to the current research on salt lake biological resources, Ding Hongxia has accompanied salt lake for 26 years.

"The earliest time was to develop daily chemical products, and later with the rise of salt lake tourism, a series of skin care products with healthy therapeutic effects on the human body were developed for the mud and salt in the salt lake. In 2014, due to the transformation of the company, I returned to the technology center and engaged in research on the conservation and development of biological resources in the salt lake. Ding Hongxia said that although the object of study has been changing for so many years, she has never left the salt lake.

The protection and development of salt lake biological resources mainly revolves around the microalgae and brine insects of salt lake, and these organisms that cannot even be seen clearly with the naked eye play a vital role in the ecological chain of salt lakes. "In the large biological chain of salt lakes, the first is microalgae through photosynthesis, continuous production and enrichment, and then planktonic halogen insects filter these algae, transformed into their own organic matter, and then provide food resources for the abundant birds in the salt lake." Birds' metabolites, feathers, etc., will be fed back to the salt lake, under the action of biochemical bacteria, these organic matter will be decomposed into nitrogen, phosphorus, amino acids, etc., providing the necessary nutrient source for algae growth, thus forming a virtuous cycle system of salt lake ecology. Ding Hongxia introduced.

In Ding Hongxia's view, the salt lake has its own characteristics in the overall structure and water quality, and to maintain the colorful colors, it must be developed in protection and protected in development. She said: "For example, like brine worms, its life cycle is mostly two or three months, if not in time to manual fishing, brine worms will rot or deteriorate, affecting water quality." If the density of brine insects is regulated by bird consumption alone, it is difficult to ensure that the water quality of each pond is in a good state. ”

In the face of such a critical and important work, Ding Hongxia not only has to overcome the difficulties in many aspects such as less equipment, less cost, less personnel, etc., but also enriches her knowledge structure through continuous learning to solve various new problems that are constantly encountered. "At that time, the staff was particularly small, and there was not much cost, and the other suddenly transitioned from the research and development of salt lake health physiotherapy products to biological research, involving a lot of marginal scientific knowledge, including which algae have what role, its form, and its impact on water, all need to be continuously recognized and understood through learning." Ding Hongxia recalled that in order to do a good job in this work, she insisted on making up for the knowledge every day, reading books and learning at night, repeatedly experimenting during the day, and then exploring according to the new problems that constantly appeared in the experiments, to overcome one problem after another.

Today, Ding Hongxia has been engaged in the research, development and protection of salt lake biological resources for seven years, and she has accumulated rich knowledge and experience in her work, and she still maintains the spirit of rigorous, studious, modest, diligent and selfless dedication of scientific workers. In the face of the launch of the ecological protection work of the salt lake "returning salt to the lake", the salt lake has entered a new stage of historical development, Ding Hongxia said: "I still have a lot of knowledge to learn, there is still a lot of work to do, I am willing to guard the salt lake for a lifetime!" ”
