The invention relates to the technical fields of energy sources and environment and discloses chemical power poly-generation energy system and method for recycling CO2. In the system, coal gas obtained by gasifying a carbon-rich raw material, and a hydrogen-rich raw material, namely, coke oven gas, are mixed and subjected to a reforming reaction and a chemical synthesis reaction to obtain a reaction product, the reaction product is processed in a flash evaporation process and a rectification process for separation to obtain CO2 gas and a final product, one part of the CO2 gas separated from arectifying tower is delivered to take part in the gasification process of the carbon-rich raw material, and the other part of the CO2 is delivered to take part in the reforming reaction. By means of the system and the method provided by the invention, the CO2 separated in the rectifying process is used as feed gas to be directly recycled by the system so that a water gas shift reaction, chemical-looping combustion and other methods with higher energy-consumption performance for improving the chemical concentration of the CO2 are avoided, the problems of reduced energy system efficiency causedby the separation of CO2 and difficulties in transporting and storing large amount of CO2 are solved, and thus, a dual-effect production mode for energy-saving and environmental-protection utilization of resources is realized.

The invention relates to an integrated system for urban road lighting, including a street lamp system and a light guide system. The street lamp system includes a plurality of hollow cylinders erected on the road surface at intervals and astigmatism lenses respectively arranged at the upper openings of the hollow cylinders; the guide The light system includes a light guide pipe arranged along the street lamp system; the lower parts of the plurality of hollow cylinders are respectively connected with the light guide pipe; strong light is introduced into the light guide pipe, and the strong light is respectively guided into the hollow cylinder after reflection, and The astigmatism lens diffuses outward to illuminate the road surface; the urban road lighting integrated system removes the self-illumination function of street lamps and replaces it with light guiding function to achieve a unified light energy supply, so it has long service life, low energy consumption, and convenient power adjustment. , the advantages of low production, installation and use costs.

The invention discloses a plant optimal configuration method for intercepting non-point source pollution and purifying water in wet land lakeside areas. The method comprises the step of plant optimal configuration for shore, lake-land ecotone and nearshore water, wherein the horizontal structure of the colonies for the plant optimal configuration shows the distribution of terrestrial plant zone, hygrophyte zone and aquatic plant zone in turn, the spire awns are planted in the terrestrial plant zone, carex dispalata is planted in the hygrophyte zone and dense eel grass is planted in the aquatic plant zone. The invention provides a plant community with an ecological function and a landscape benefit; through the optimal configuration for the plant community, the non-point source pollution, such as, overland runoff, of the natural water in lakes and rivers can be effectively intercepted; the pollution in the water in the wet land lakeside areas can be absorbed and cleaned; the survival rate of the plant community in the wet land lakeside areas can be increased.

The invention discloses a microbial insecticide, which is characterized by comprising, by weight percentage, 30-50% of a bacillus thuringiensis liquid, 30-50% of a beauveria bassiana bacteria liquid, 5-9% of a photosynthetic bacteria liquid, 5-9% of a yeast bacteria liquid, 5-7% of a tobacco leaf chelate liquid, 1-3% of potassium dihydrogen phosphate, 0.05-0.2% of DA-6, 0.05-0.3% of compound sodium nitrophenolate, and 0.1-0.4% of organosilicon. The microbial insecticide provided by the invention can replace chemical insecticide pesticides, and has the characteristics of low cost, obvious control effect, broad spectrum and lasting effect, no side effect, no residual and the like. In addition to the insecticidal and bacteriostatic effects, the insecticide is also blended with some crop necessary fertilizers N, P and K (in addition, also a variety of trace elements and crop necessary minerals), the simultaneous fertilization step is omitted, and the purpose of multiple effects at one time can be achieved. The microbial insecticide has the advantages of low cost, strong effect, and high degree of environmental protection.

The invention provides a pesticide composition for bagging pre-treatment of grapes. The pesticide composition is prepared from the following raw materials in parts by mass: pyraclostrobin, fludioxonil, potassium humate and chitosan in a mass ratio of (1-25) to (1-25) to 5 to 5. The pesticide composition for the bagging pre-treatment of the grapes, provided by the invention, is mainly used for preventing and treating anthracnose, botrytis and downy mildew of the grapes, has no problem of cross resistance, can be used for delaying the occurrence and development of the pesticide resistance of pathogens, and has a long persistent period and remarkable fungicidal effect; and the use amount of pesticides can be reduced, the pesticide utilization cost is reduced, and damages and pollution caused by the pesticides to the ecological environment are reduced; and meanwhile, a plurality of effects can be reached by utilizing the pesticide composition for one time and the labor intensity is also alleviated.
