He has just come back from America. Because of the need of experimental research, he wanted to buy five or six incubators with different temperatures, and limited funds could not buy them, so he began to design and trial-produce them himself. For the most critical part of the temperature regulator, he used the boiling point difference of different solvents, such as ether and acetone, to pour several mixed solvents with different proportions into a thin copper sheet container for use as a temperature regulator. The price of the self-made incubator is only 1 and 6/of that of imported products, and its performance is good, which successfully solves the urgent need of scientific research and experiment.
During my stay in Meitan, due to the lack of electricity in the town, the electric thermostat brought from Hangzhou could not be used, and many experiments and students' graduation thesis could not be completed. Chen Hongkui is determined to solve the energy problem of the incubator. He used the rich charcoal resources in Meitan at that time to carry out experiments. First, he mixed charcoal powder, starch, clay and water, found out the most suitable proportion, made it into paste, molded it into rectangular charcoal strips with certain specifications with wood, and dried it for later use. However, the heat preservation conditions required by experiments and scientific research require that carbon strips be shaped, not fragile or broken, and can emit heat evenly, slowly and continuously when ignited. He used the principle of heat, and after dozens of experiments, he finally made a carbon belt that could burn continuously for 24-48 hours. The indoor temperature is higher than the room temperature (about 65438 00℃) by more than 65438 05℃. This meets the requirements of pathogen culture.
Chen Hongkui has been teaching for decades and is famous for his rigorous style of study. Taking the scientific name of medicinal fungus "Wan Lei" as an example, it is enough to illustrate his earnest and meticulous spirit. When participating in the compilation of Medicinal Flora of Zhejiang Province, in order to determine its scientific name, Chen Hongkui first asked people to collect more fresh sclerotia from Wan Lei in bamboo forests all over Zhejiang Province, and then after many experiments in the laboratory, he explored the most suitable conditions for promoting sclerotia germination and eventually growing fruiting bodies. After several months of observation, it was confirmed that basidiocarp was a pleated mushroom. After identification, it is confirmed that this mushroom is Leiwan, but in some books and papers of medicinal fungi in China, when it comes to "Wan Lei" including Zhejiang Province, its scientific name is Polyporus. This is mainly due to mutual citation, unauthentication and misinformation. Because of his rigorous scholarship, he finally corrected this mistake.
The second characteristic of his rigorous style of study is that he is strict with students and insists on integrating theory with practice. In the 1950s, when he personally went to the mountainous area in southern Zhejiang to guide students to investigate and practice the black spot disease of sweet potato, he carefully guided them to sum up their experience and read their reports carefully. It is equally strict in the classroom and laboratory, which not only guides students to read original materials and documents, but also expands their academic ideas, and emphasizes the integration of theory with practice to apply what they have learned. He attaches importance to correctly mastering standardized technical operations and personally demonstrating them; He severely criticized those students who left at will or didn't move in the right way after using the microscope.
Chen Hongkui is humble, approachable and enthusiastic about the growth of students. Tell visitors everything they know and answer all their questions. When he meets a question that is difficult to answer at the moment, he keeps it in mind, and then meticulously consults the literature to give the other party a satisfactory answer as much as possible. He often revises and revises the translations of professional documents read by students. Every time he sees their success, he is very happy, but he never talks about his fame and contribution. He deeply influenced every student with his practical actions. Over the years, he has trained a batch of backbone forces for the agricultural front in China. Everyone thinks that Mr. Chen Hongkui deserves to be a model for us to learn in the process of socialist modernization in our motherland.
