The invention relates to the field of nucleic acid fluorescence detection, in particular to a reagent and a method for detecting single-gene RNA G4 through fluorescence imaging and application of the reagent and the method. According to the invention, an RNA G4 structure targeting module and a gene sequence targeting module are adopted and are simultaneously combined to a target gene sequence and an rG4 structure in a dual-module targeting form to trigger a click chemical reaction close to triggering in a space so as to generate a nucleic acid chain of a specific sequence restored by the click chemical reaction; then, the nucleic acid sequence is used as an initiation chain, through HCR reaction, hairpins H1 and H2 are initiated to be subjected to cascade reaction, a long repeated double-chain DNA product is obtained, and fluorescence signal amplification detection can be achieved. The method has a wide application prospect.

This invention discloses a system for producing ammonium sulfite using electrolytic manganese ammonium sulfate double salt. The system includes a drum high-temperature drying device. The electrolytic manganese ammonium sulfate mixture output from the drum high-temperature drying device is fed into a crushing device via an elevator. The electrolytic manganese ammonium sulfate mixture output from the crushing device is fed into an anaerobic calcining furnace. A three-stage electrostatic precipitator is connected to the rear end of the anaerobic calcining furnace. The exhaust gas, after dust removal by the three-stage electrostatic precipitator, is sent to a multi-stage absorption and conversion tower via an exhaust gas pipeline. The conversion liquid and the completed absorption liquid after passing through the multi-stage absorption and conversion tower are sent to an evaporation device. This system and method for producing ammonium sulfite using electrolytic manganese ammonium sulfate double salt improves the calcination effect through pretreatment such as drying and crushing, and ultimately converts the ammonium sulfate into sulfur dioxide through anaerobic calcination to prepare ammonium sulfite. The difference lies in the direct blending and calcination method used in domestic and international processes.

The invention relates to the technical field of agriculture, in particular to a facility vegetable field repairing agent and a preparation method and application thereof. The facility vegetable field repairing agent comprises boric sludge doped kitchen waste biomass charcoal, amino-functionalized diatom mineral powder, a growth-promoting and disease-inhibiting compound and a photosensitive active soil conditioning compound. According to the invention, an environment-friendly concept of treating pollution with waste is adopted, agricultural waste resources such as boric sludge, kitchen garbage, silkworm excrement, kitchen compost and the like are fully utilized, and a scientific formula and a modification process are adopted; the powdery facility vegetable field repairing agent with multiple functions is compounded by doping the boric sludge with the kitchen waste biomass charcoal, the amino-functionalized diatom mineral powder, the growth-promoting and disease-inhibiting compound and the photosensitive active soil-adjusting compound. The test shows that the compound has the positive effects of relieving soil acidification, improving soil fertility, passivating heavy metal cadmium, promoting crop growth, inhibiting growth of fusarium oxysporum, reducing cucumber morbidity and the like, and is beneficial to solving the problems of degradation of facility vegetable fields and cadmium pollution.

The present invention relates to the field of aviation test flight technology, and discloses a test flight platform suitable for robot pilots, which is formed by modifying a retired aircraft, that is, removing some mechanical components, some electrical components and some radio components in the retired aircraft. A flight control subsystem, a measurement and control subsystem, an electrical subsystem and a ground test subsystem are installed. The flight control subsystem includes an optical fiber attitude and heading, an atmospheric data computer, a flight control computer, an elevator servo, an aileron servo, a steering servo, auxiliary equipment and a throttle motor. The optical fiber attitude and heading are connected to the flight control computer for two-way communication; the ground test subsystem is connected to the flight control computer for two-way communication, and is used to send route information and initial parameters to the flight control computer, and receive the working status information of each device included in the retired aircraft, the information cross-linking status of the flight control subsystem and other subsystems, and the binding parameters. The present invention has the advantages of high technical feasibility, low cost, and strong scalability.
