On the morning of August 10th, the "2019 Heilongjiang Basic-level Agricultural Technology Promotion Backbone Talent Training Course" hosted by Heilongjiang Provincial Aquatic Technology Promotion Station and undertaken by Panjin Guanghe Crab Industry Co., Ltd. officially opened at the Panjin Red Beach Wetland Science Museum. 33 elite students from the aquatic industry in Heilongjiang Province, led by Zou Min and Zhang Xubin, the head of the Heilongjiang Fisheries Technology Promotion Station, started a four-day professional course in aquatic products.

Mr. Li Xiaodong, the chairman of the board, delivered a speech for the students based on his personal experience in recent years. He pointed out that the rice field crab breeding model has achieved rapid development in the north, and with the formation of the northern characteristics, the fishery industry in Heilongjiang Province has also achieved rapid development. Photosynthesis has been devoted to aquaculture research for many years and is the pioneer of the rice field crab breeding model. After years of promotion of agricultural technology, especially the rice field crab breeding technology, he has achieved certain results. He wished the students in the next few days. In learning and life, there is something to gain. Director Zou announced the official start of the "2019 Heilongjiang Basic-level Agricultural Technology Promotion Backbone Talents Training Course", and focused on the class discipline and learning requirements, hoping that all the trainees will achieve something in their learning. Zou Min, the head of the station, awarded the plaque of "Heilongjiang Crab Breeding and Breeding Technology Training Base" to Li Xiaodong, Chairman of Panjin Guanghe Crab Industry Co., Ltd. The company's vice president of production, Chai Yongqing, and vice president of R&D, Liu Wei, participated in the awarding of the plaque.

Sun Na, chief engineer of the Photosynthetic R&D Center, gave a lecture on "Basic Biological Knowledge of River Crabs". Teacher Sun Na explained the classification, origin of the name, crab culture, the external shape and internal structure of the crab, various developmental stages, reproductive characteristics, growth characteristics, the relationship between growth and development and environmental factors and other biological characteristics. In order to let the students have a deeper understanding of the relationship between the growth and development of river crabs and the environmental factors such as temperature, salinity, pH, light, oxygen, ammonia nitrogen, nutrients, aquatic animals and plants in the waters where they are located, Ms. Sun Na led the students to enter the photosynthetic water chemistry The laboratory patiently operates, demonstrates and explains various detection methods and operation essentials of water quality indicators for students from the perspective of biochemistry.

Liu Wei, chief engineer and senior engineer of Panjin Guanghe Crab Industry Co., Ltd., gave a lecture on "Ecological Breeding Technology of River Crabs". Chief engineer Liu Xu explained the characteristics of breeding technology and common breeding methods at home and abroad, and focused on the breeding principle of the first national-level new crab variety "Guanghe No. 1" born after more than 10 years of breeding. The group introduced the unique advantages of "Guanghe No. 1" in terms of the metamorphosis rate of macroeye larvae, the recapture rate of family crab breeding, and the distribution of catches in the same pond, fully demonstrating that "Guanghe No. 1" is a guarantee of high quality.

Facing the questions and difficulties raised by many students about the crab breeding process, Chief Engineer Liu Xu used his scientific research experience in the crab industry for more than 20 years to analyze and answer the students carefully and patiently.

Li Xiaodong, chairman of Guanghe Crab Industry Co., Ltd. and an expert who enjoys special government allowances from the State Council, gave a lecture on "New Advances in Rice Field Crab Raising Technology". Professor Li Xiaodong said that the integrated rice-fishing planting and breeding business has encountered a very good opportunity, because the "environmental protection storm" will affect aquatic products. The aquaculture industry has been redefined. According to the country's five development concepts, high-density pond aquaculture should be controlled or reduced, and the way of producing aquatic protein has undergone major changes. If the aquatic industry wants to make breakthroughs in links, it must first make breakthroughs in breeding. Photosynthesis will continue to research and develop new varieties targeting shell color, meat quality, disease resistance and stress resistance, and is committed to the development of matching line breeding technology to meet the needs of the market and the in-depth research and promotion of rice and crab comprehensive breeding technology that meets the needs of the modern agricultural industry. .

The leaders of the Heilongjiang Aquatic Products Technology Promotion Station and the trainees of the training course visited the Chinese velvet on the spot, accompanied by the general manager of the company Sun Xiaosong, the deputy general manager Chai Yongqing, the general manager of the popular science and agriculture service center Ma Min, and the directors of the R&D center Zheng Yan and Yang Zhanquan. The crab breeding base also told the students about the water quality control technology, the rice field transformation technology, the intensive cultivation technology of large-sized first-year crabs in spring, and the setting technology of temporary ponds, as well as the specific solutions to specific problems.

Zheng Yan, director of research and development and senior engineer of Panjin Guanghe Crab Industry Co., Ltd., gave a lecture on "Crab Breeding in Rice Fields".

Mr. Zheng Yan introduced the significance and characteristics of crab farming in rice fields, emphasized the prominent role of the crab farming model in rice fields in achieving food safety and increasing farmers' income, and described in detail the crab farming project in rice fields, the breeding and management of large-scale farming, and the harvesting of crabs. The essentials and precautions of breeding technology.

Yang Zhanquan, R&D director and engineer of Panjin Guanghe Crab Industry Co., Ltd., gave a lecture on "Crawling of Adult Crabs in Rice Fields". Teacher Yang Zhanquan first introduced the characteristics of adult crab farming and the conditions of adult crab farming, and then focused on the selection of seedlings for adult crab farming in paddy fields, the criteria for judging the selection of breeding environment, the management of rice planting, and the breeding management of large-scale farming. The specific operation methods and problems that need attention.

Ma Min, general manager of Panjin Guanghe Science and Technology Benefiting Agriculture Service Center, analyzed the advantages of "Guanghe No. 1" ecological crab seedlings. As the person in charge of the sales of "Guanghe No. 1" ecological crab fry, Mr. Ma Min starts from the crab hatching process, the method and date control of crab fry, the method of order sales, and the actual situation of crab fry sales in the market every year. For the students, it further analyzed and explained the reasons why the "Photosynthesis No. 1" ecological crab seedling occupies an absolute dominant position in the crab seedling market.

Sun Zhongzheng, deputy general manager of the company, Ma Min, general manager of the popular science and agriculture service center, and Zheng Yan and Yang Zhanquan, the R&D directors, answered the questions of the trainees in detail.

Heilongjiang Provincial Aquatic Technology Promotion Station issued a letter of appointment to the Guanghe team, and formally appointed Ma Min, general manager of Panjin Guanghe Science and Agriculture Service Center, and Yang Zhanquan, R&D Director of Panjin Guanghe Crab Industry Co., Ltd. as specially-appointed fishing technicians, and will be Heilongjiang River Crabs in the future. The development of the aquaculture industry continues to provide long-term technical guidance.

This training course for the backbone talents of grass-roots agricultural technology promotion in Heilongjiang Province was successfully concluded. As "Heilongjiang Province River Crab Breeding and Breeding Technology Training Base", the R&D and technical team of Photosynthesis will definitely live up to its mission. He has a solid foundation in the field of breeding, and contributes to the development of aquaculture and personnel training in Heilongjiang Province, as well as to the vigorous development of rice and fishery comprehensive planting and breeding in the north.
