The invention discloses a microbial carrier implantable soil microstructure improvement device and method, the device takes microbial carrier precise implantation as a core, integrates multiple functions of targeted layered implantation, carrier-soil microstructure synchronous reconstruction, microcapsule in-situ activation and the like, and can improve the soil microstructure through an intelligent regulation and control system and modular design. And efficient improvement of the soil microstructure in different soil layers and different scenes is realized. The device comprises a power module, a control module and a switchable function module, innovatively adopts a targeted layered injection mechanism, a carrier-soil mixing and shaping assembly and an environmental response type microcapsule spray-seeding activation module, and is matched with a degradable carrier material modification assembly and a new energy driving system. The problems that a traditional device carrier is low in implanting precision, not tightly combined with soil, single in application scene and the like are solved.

The invention relates to the field of soil pollution remediation, and discloses a micro-ecological reconstruction and remediation method for micro-plastic polluted soil, which comprises the following steps: firstly, screening and enriching micro-plastic degradation functional florae which have the advantages of pseudomonas and bacillus, and the bacillus can secrete lipase and protease; the preparation method comprises the following steps: mixing biomass charcoal prepared by pyrolysis of corn straws with a functional bacterium suspension for adsorption, and carrying out sodium alginate-calcium chloride crosslinking to prepare an immobilized composite repairing agent; applying a repairing agent accounting for 1-5% of the mass of the soil, uniformly mixing the repairing agent with the soil, regulating the soil humidity to 20-30% and the carbon-nitrogen ratio to (15-25): 1, and maintaining the environment temperature of 15-35 DEG C; microplastics are removed through the synergistic effect of biomass charcoal adsorption and functional flora enzymatic degradation, beneficial microorganisms are enriched synchronously, and functional gene expression is activated; the problems that in the prior art, functional flora planting is difficult, the degradation efficiency is low, micro-ecological restoration is deficient, and the environmental adaptability is poor are solved.

The invention provides a composition for improving the intestinal bacterial phase and prolonging the colonization rate of beneficial bacteria in the intestinal tract, the composition comprises Bifidobacterium lactis GKK2, and the composition can be used for improving the intestinal bacterial phase, promoting the colonization rate of the beneficial bacteria in the intestinal tract and prolonging the activity of the beneficial bacteria in the intestinal tract.

The invention discloses compound lactic acid bacteria, a metagen and a preparation method and application of the compound lactic acid bacteria and the metagen. Through composite compatibility of the probiotics separated from the yak yoghurt in the Qinghai-Tibet Plateau, a synergistic effect of various strains is exerted, negative effects caused by treatment by using a medicine means are avoided, side effects are avoided, and the problems of single effective microbial community, low regulation capability and the like in the prior art are solved. By adding the selective auxiliary materials, the survival rate of the compound probiotics after freeze-drying treatment is improved, the probiotics can more effectively resist the adverse environment of the gastrointestinal tract, the problems that in the prior art, the probiotics are prone to being damaged by gastric acid, the survival rate is reduced in the storage process, and a large amount of probiotics are inactivated before entering the intestinal tract are solved, the planting rate of the probiotics is increased, and the survival rate of the probiotics is increased. The effect is more durable and more stable. Through synergistic compatibility of the composite probiotics and functional prebiotics from characteristic plant resources from the Tibet Plateau, the intestinal flora balance adjusting capacity is improved, and the beneficial effects of effectively improving symptoms such as constipation and obesity are further achieved.

The present application relates to the prairie repair technical field, especially in kind of degraded prairie repair fungicide, granular repair fungicide and amendment and application thereof.The present application provides the degraded prairie repair fungicide by the preservation number of fluorescent pseudomonas T6 and the preservation number of the alfalfa sinorhizobium NFB5 of CGMCC NO.33618, and the degraded prairie repair fungicide provided by the present application is composed of the preservation number of fluorescent pseudomonas T6 and the preservation number of the alfalfa sinorhizobium NFB5 of CGMCC No.36876.The fluorescent pseudomonas T6 in the degraded prairie repair fungicide provided by the present application and the alfalfa sinorhizobium NFB5 two compound have the synergistic effect, and the repair effect to the degraded prairie is good, and the strain colonization rate is high.The present application relies on the native resources (sheep manure, peat soil, local microorganism and native grass species) of Inner Mongolia grassland, and gives consideration to ecological repair and livestock production, realizes the integration repair of "soil-microorganism-vegetation" three-dimensional synergy, and has important technical innovation value and practical application significance.

The application discloses a liquid injection device and method for in-situ biological gas production of residual coal in a closed goaf, and relates to the technical field of coal bed gas exploitation. The device comprises a bacteria liquid supply mechanism, a gas supply mechanism, a gas-liquid mixing mechanism and an injection mechanism. The bacteria liquid supply mechanism is used for providing bacteria liquid containing methanogenic bacteria groups. The gas supply mechanism is used for providing carbon dioxide gas. The gas-liquid mixing mechanism is connected with the bacteria liquid supply mechanism and the gas supply mechanism respectively. The gas-liquid mixing mechanism can use the negative pressure generated by the flow of the bacteria liquid in the gas-liquid mixing mechanism to suck the carbon dioxide gas into the gas-liquid mixing mechanism to break it into micro-bubbles, and make the micro-bubbles mix with the bacteria liquid to form gas-liquid two-phase flow. The injection mechanism is connected with the gas-liquid mixing mechanism and is used for dispersively injecting the gas-liquid two-phase flow into the residual coal cracks in the closed goaf. The application can effectively overcome the phenomenon of finger advancement, effectively expand the penetration depth, and effectively improve the activity and planting rate of the bacteria groups.
