The invention relates to a Pseudomonas plecoglossicida pldB gene deletion mutant strain and a preparation method and application thereof, and belongs to the technical field of microorganisms and the field of algae preservation, the pldB gene of the mutant strain is deleted or inactivated, the nucleotide sequence of the pldB gene is shown as SEQ ID NO: 1, and the GenBank accession number of the Pseudomonas plecoglossicida is CP031146.1. The virulence of the mutant strain is obviously reduced compared with that of a wild strain of pseudomonas plecoglossicida; the strain can induce appropriate immune response of a host and up-regulate expression of anti-inflammatory factors, is beneficial to relieving immune pathological injury, has good attenuated live vaccine potential, and provides a brand new vaccine candidate strain for prevention and control of the visceral white-spot disease of the large yellow croaker.

The utility model relates to the technical field of breeding incubator, specifically to a kind of small goose breeding incubator, it includes: incubator and flat plate, and two three blocks are slidably connected in flat plate inner side, and the inner wall of both sides of incubator is uniformly provided with the clamping groove compatible with three blocks, three blocks outside is movably inserted in the inner side of clamping groove, and four blocks are fixedly connected in three blocks side, and four blocks side is rotatably connected with connecting rod, and the other end of two connecting rods is rotatably connected with five blocks, and five blocks inner side is screw-threaded with screw rod, and screw rod outside is rotatably connected in flat plate inner side, and two external threads of opposite rotation are set in screw rod outside, and multiple feeding bowls and water bowls are provided on flat plate top. The utility model, by the cooperation between block, three blocks and connecting rod, so that the user can conveniently fix flat plate with device, so that the user can quickly disassemble it, facilitate user to clean it, further improve the working efficiency of user.

The application discloses a kind of dynamic metabolic regulation escherichia coli fermentation preparation alpha-ketoisovaleric acid method, belong to the field of bioengineering.The recombinant escherichia coli constructed contains the dynamic regulation cell growth metabolic pathway and balance coenzyme circulation system established based on CRISPRi technology and degradation label;It can be with cheap glucose as carbon source, with inorganic salt as nitrogen source, and ferment to generate high value-added alpha-ketoisovaleric acid, under the fermentation strategy of two-stage fermentation, the yield of alpha-ketoisovaleric acid can reach 35.2g / L for 60h, with the prospect of industrial application.

This invention discloses an intelligent management method and system for agricultural greenhouses based on artificial intelligence, relating to the field of electrical data analysis technology. It includes coordinate planning processing of the locations of all monitoring devices inside the agricultural greenhouse. This invention calculates all monitoring data from the devices to determine if any abnormal data changes occur inside the greenhouse. Once an abnormal data change is identified, its location is determined, and path planning is performed to determine the maintenance path for that location. However, some abnormal data changes may not cause changes to the greenhouse environment or affect crop growth. Therefore, real-time operational data at the location of the abnormal data change is compared and analyzed to determine whether maintenance is necessary. This method not only ensures normal crop growth inside the greenhouse but also reduces greenhouse maintenance costs.

The present application relates to the technical field of planting, in particular to a method for improving seed germination rate and leaf growth of passion fruit. The present application can improve the seed germination rate of passion fruit by soaking passion fruit seeds in ganoderma lucidum solution for a suitable time; by spraying ganoderma lucidum and foliar fertilizer on the leaves of passion fruit plants, the symptoms of viral diseases of the plants can be obviously improved, the use of pesticides can be reduced, the effect of reducing pesticide residues can be achieved, the passion fruit leaves can grow normally, and the leaf growth can be improved.
