The academician expert workstation is an industry-university-research collaboration platform established by academicians and their expert teams and enterprises. Since 2003, under the vigorous promotion of relevant units and departments such as China Association for Science and Technology, Chinese Academy of Engineering, etc., academician and expert workstations have developed by leaps and bounds. Up to now, there are nearly 5,000 "academician and expert workstations" nationwide.

Gui Jianfang said that this model enabled his team to work closely with local companies and river crab farmers, "not only found more scientific research topics from the fields, but also supported by scientific research results, promoting local river crabs. Industrial development of aquaculture".

Crab farming in paddy fields is an aquaculture that utilizes paddy field wetland resources under the premise of ensuring stable rice production, forming a seasonal production model combining farming and fish farming.

"This 'rice-crab symbiosis' farming method has many benefits. The crab and the rice are mutually beneficial. The crab feeds on the pests of the rice field, and the excrement can fertilize the rice field. The rice provides a place for the crab to hide, and the crab and the rice form a It not only improves the income of farmers, but also effectively promotes the development of organic agriculture.” Li Xiaodong, chairman of Panjin Photosynthetic Crab Industry Co., Ltd., told a reporter from China Science News.

In order to make the crabs in Panjin fatter and the rice more fragrant, since the establishment of the academician and expert workstation, Gui Jianfang has led the scientific research team to guide the scientific research work of the enterprise many times.

Gui Jianfang said, "Our country is transitioning from traditional rice-fish farming to rice-fishing integrated farming and farming. This model is to effectively control rice while making full use of the ecological function advantages of the food chain required for the growth of aquatic animals and the nutritional needs of rice growth. Diseases and insect pests and weeds in paddy fields increase water nutrients, improve soil fertility in paddy fields, reduce the use of chemical fertilizers and pesticides, reduce non-point source pollution, improve the ecological environment, and produce more quality and safe rice and aquatic products.”

Li Xiaodong introduced that under the guidance of the academician team, they led the local crab farmers to focus on the new species of river crab "Guanghe No. 1", with the goal of building a 'comprehensive rice-fishing planting and pastoral complex', focusing on rice field planting, deduction A series of supporting technologies have been developed in crab farming, adult crab farming, shrimp and crab farming, and safe overwintering, forming a complete farming model.

"Comprehensive rice and fish farming can become a technical starting point for rural ecological civilization construction and rural revitalization strategy," Gui Jianfang emphasized that at present, most provinces and cities across the country have carried out "rice and shrimp continuous cropping + co-cropping" and "rice-crab co-cropping". "Co-cropping of rice and turtle + crop rotation", "Co-cropping of rice and turtle", "Co-cropping of rice and loach", "Co-cropping of rice and fish" and many other typical integrated rice and fish farming models. In the future, it is possible to build an ecological picture of rice, fishery, and fish farming in which "fish jump in the water and fruits fall in the mountains".

Today, under the guidance and help of the academician team, the workstation has applied for 2 patents, and is preparing to publish 3 papers. Such projects will become a powerful starting point for the construction of "Pastoral Complex", beautiful countryside and ecological civilization.
