The invention discloses a compound microorganism liquid bacterial fertilizer for preventing plant diseases and insect pests and a preparation method of the compound microorganism liquid bacterial fertilizer and belongs to the technical field of microorganisms. The bacterial fertilizer comprises raw materials of, by weight, 10-20 parts of paprika powders, 10-20 parts of chilli powders, 5-15 parts of ginkgo leaf powders, 5-15 parts of chinaberry powders, 5-15 parts of lightyellow sophora root powders, 20-40 parts of mashed garlic, 40-80 parts of molasses, 4-8 parts of soybean meal, 5-15 parts of calcium sulfate, 5-15 parts of magnesium chloride, 5-10 parts of salt, 5-15 parts of photosynthetic bacterium strains, 5-15 parts of saccharomycete strains, 5-15 parts of lactic acid bacterium strains, 5-15 parts of streptomyces jingyangensis strains, 5-15 parts of bacillus subtilis strains and 800 parts of water. According to the compound microorganism liquid bacterial fertilizer, probiotic floras which are screened and are capable of coexisting are used for fermenting plant leaching agents of pepper, chilli, ginkgo leaves, chinaberry, lightyellow sophora roots and garlic, the plant leaching agents are capable of expelling and killing the insect pests and harmful bacteria, the compound microorganism liquid bacterial fertilizer has the advantages of being high in content of live bacteria of probiotics, high in activities, high in stability, small in using amount of plant materials, fast in acting effects, non-toxic and environment-friendly, and has wide application prospects in agricultural planting.

The invention discloses a soil improver suitable for remediation of polluted soil on site, its preparation method and application, wherein the soil improver is composed of the following raw materials: steel slag, magnesium sulfate, industrial sludge, binder, distiller's grains, etc.; The binder is composed of clay, water and vetiver with a mass ratio of 3 to 9:1 to 3:0.5 to 1.5; the invention is a soil improver suitable for remediation of contaminated soil on site, suitable for the original site of industrial enterprises, and can be The total porosity of the soil is increased from the original 30% to 50%, which can improve the water absorption capacity of the soil; and the pH value of the soil is improved from 4 to 6 to 7 to 9; and the density of the soil improver of the present invention is close to the soil density 1.3~1.6t / m 3 , so that it can better integrate with the soil and play its role in soil restoration.

The invention discloses a method for restoring eutrophic water body, which comprises the following steps: 1. The eutrophic water body restoration medicament is prepared by using water, oxygen release agent, biomass charcoal powder, compound bacterial agent, alkali agent and binder. ; Second, the application of chemicals to eutrophic water bodies. The eutrophication water body restoration method of the invention has the advantages of high removal rate, low cost, environmental friendliness and the like, and can efficiently and lastingly restore the eutrophication water body.

A method for preparing silicon carbide nanowire in-situ growth toughened ceramic precursor high-temperature glue. It includes the use of vinyl polycarbosilane, polymethicone, phenolic resin, ferrocene and isopropanol to prepare gum base fluid, aluminum powder, nickel powder, silicon powder, boron carbide powder and borate glass powder As a filler mixture, the steps of preparing high-temperature glue by mixing the gum base liquid and the filler mixture. The effect of the present invention: the high-temperature adhesive can grow silicon carbide nanowires in situ at 1100°C to be strengthened and toughened, so that its bonding performance is greatly improved in the range of 1100-1500°C, especially after 1300°C, the high-temperature The bonding strength of the glue at room temperature is 59.2% higher than that of the blank sample without nanowire growth. After in-situ growth of silicon carbide nanowires, the high-temperature adhesive exhibits good toughness at room temperature and high temperature, and the fracture displacement curve of the bonded bonded parts has an obvious approximate yield stage, which fully shows that the high-temperature adhesive has Very high safety in use.

The embodiment of the invention discloses a method, a device and a system for maintaining a storage battery. In the embodiment of the invention, frequency points of a sweep frequency phase shift power pulse wave which can generate resonance with lead sulfate crystals are set according to different resonance points of the lead sulfate crystals of different sizes in a storage battery electrolyte; the crystals are subjected to resonant processing, sharp pulse current is generated under the control of the pulse wave to crush the crystals subjected to the resonant processing, and the crushed crystals are dissolved into the electrolyte of the battery, so that the small-granular lead sulfate crystals are converted into lead and lead dioxide during the charging and discharging of the storage battery in the input process of the sharp pulse current; and thus, the aim of maintaining the performance of the storage battery is fulfilled.
