The invention discloses a multifunctional peoriae paenibacillus and application thereof, and relates to the technical field of microorganisms, and the key point of the technical scheme is as follows: Paenibacillus peoriae S6330 is separated from rhizosphere soil; the peoriae paenibacillus has a good inhibition effect on pathogenic bacteria, pathogenic fungi and oomycetes; meanwhile, the peoriae paenibacillus has the functions of dissolving potassium, producing protease, producing amylase, producing cellulase, producing siderophore and the like, has a growth promoting effect on various crops such as wheat, corn, watermelons, small oilseed rapes, tobaccos and the like, and can remarkably improve indexes such as chlorophyll content, plant height, fresh weight, overground part weight, underground part weight and the like of plants; in addition, the peoriae paenibacillus can be used for effectively inhibiting the tobacco bacterial wilt; the peoriae paenibacillus has no environmental pollution problem, is simple in culture condition, and has wide disease prevention and growth promotion application prospects in agricultural production.

The invention discloses a ternary sand-fixing water-retaining seepage-proofing fertility-increasing vegetation restoration and reconstruction method, and relates to the technical field of operation methods of sand ecological restoration, and the method comprises the following steps: S1, laying a layer of seepage-proofing material on the surface layer of a target planting area to reduce water seepage and enhance soil water-retaining capacity; s2, mixing a water-retaining agent with local sandy soil to form a water storage layer, and paving the water storage layer on the surface of the impermeable material to ensure that the plant root system can obtain water for a long time; s3, applying an organic fertility intensifier to the water storage layer to improve the organic matter content and nutrient supply capacity of the soil; s4, appropriate plants are selected for planting, after planting, the vegetation growth condition and the soil humidity are checked regularly, a water-retaining agent and an organic fertility increasing agent are supplemented in time according to needs, and it is ensured that the vegetation can grow healthily. The planting method provided by the invention has a remarkable yield increasing effect, the survival rate of plants can be effectively improved, and the effect of fixing sand for a long time is achieved.

The invention discloses a high-efficiency phosphate-solubilizing salt-tolerant growth-promoting pseudomonas deliciosa and application thereof, and relates to the technical field of microorganisms, and the technical key points are as follows: the pseudomonas deliciosa HX144 is preserved in China General Microbiological Culture Collection Center (CGMCC) in October 2024, and the preservation number of the pseudomonas deliciosa HX144 is CGMCC NO.32292. The Pseudomonas deliciosa HX144 provided by the invention is high in phosphate solubilizing activity and strong in salt tolerance, the dissolved available phosphorus content of the Pseudomonas deliciosa HX144 is up to 195.75 + / -0.5 mg / L, and the Pseudomonas deliciosa HX144 can tolerate a culture medium environment in which the NaCl concentration is up to 6%. And the strain has a good inhibition effect on plant pathogenic bacteria and human and / or animal pathogenic bacteria. In addition, the strain also has the functions of producing protease, plant growth hormone, siderophore and the like. The strain has a growth promoting effect on wheat crops and can remarkably improve indexes such as plant height, fresh weight and root length of plants. HX144 is an excellent salt-resistant, disease-preventing and growth-promoting pseudomonas strain, and has a wide application prospect in agricultural production.

The invention discloses an environment-friendly culture medium and application thereof, and belongs to the technical field of soilless culture. The environment-friendly culture medium comprises peat, vermiculite and perlite, and further comprises one of fermented fibers or a small-particle water-retaining agent. When the environment-friendly culture medium disclosed by the invention is applied to the cultivation of the azalea container seedlings, the dosage of required water and fertilizer is reduced, the growth of the azalea container seedlings can be effectively promoted, and the amount of the azalea is increased.

The utility model discloses a kind of strain culture shaker, specifically related to strain culture technical field, including shaker base plate, shaker base plate top is slidably connected with moving stage, and moving stage top is provided with oscillation mechanism, and horizontal shaking mechanism is arranged between shaker base plate and moving stage;Oscillation mechanism includes lifting plate, and lifting plate is set in moving stage top, and sliding hole is opened in lifting plate.The utility model is placed in moving stage on strain culture test tube by setting horizontal shaking mechanism, and it is shaken along with, so as to let the nutrient substance in culture medium be fully mixed and evenly distributed, ensure that strain can obtain sufficient nutrient in each place in growth process, provide good nutrient environment for the growth of strain, improve the utilization efficiency of strain to oxygen and nutrient substance, and strong oscillation effect can make strain keep suspended state, avoid strain to be deposited in container bottom, prevent from affecting growth due to strain uneven distribution.
