The present application relates to a kind of efficacy composition for preventing and treating tobacco root-knot nematode, fertilizer synergist and its application, the efficacy composition includes α-triphenyl and slightly fermented fertilizer;The slightly fermented fertilizer is respectively with the stem of continuation of stem, the stem of three-leaf bidens and the stem of dandelion as raw material, after cooking treatment, steam explosion treatment, microbial fermentation liquid soaking treatment, fermentation treatment, dry after the three kinds of fermentation products obtained by mixing are obtained.The slightly fermented fertilizer prepared by using specific preparation process can significantly improve the killing efficiency of α-triphenyl on root-knot nematode, and the combination of α-triphenyl and α-triphenyl can synergize, so that the killing effect of α-triphenyl on root-knot nematode is still very good at low use concentration, and the mortality of root-knot nematode is as high as 90%.

A method for preparing a composite photoelectrode for glucose content detection includes the following steps: adding potassium iodide and bismuth nitrate pentahydrate to a nitric acid solution, adding p-benzoquinone to ethanol, and mixing to obtain electrolyte A; depositing a BiOI thin film on FTO conductive glass using an electrochemical method; dripping a dimethyl sulfoxide solution of vanadium acetylacetonate onto the surface of the BiOI thin film, calcining it, immersing it in NaOH solution, rinsing it, and drying it to obtain a BVO photoelectrode; adding lithium perchlorate and terthiophene to acetonitrile to obtain electrolyte B, and performing photoelectrodeposition on the BVO photoelectrode using an electrochemical method to obtain the composite photoelectrode. The preparation method of this invention is simple and safe to operate, uses readily available materials, and can be mass-produced; the prepared composite photoelectrode, combined with photoelectric detection technology, can detect glucose content, exhibits high stability, simple steps, rapid response, and high sensitivity, providing a new analytical method for glucose content determination.

The application discloses a synthesis method and application of a fluorescent probe for lipase detection, and the fluorescent probe has the following structural formula; the synthesis method comprises the following steps: under the action of inert gas protection, a catalyst and alkali, triphenylol compound and a fatty chain or an aromatic ring organic acid are reacted in an organic solvent at 25-100 DEG C for 8-24h; after the reaction is stopped, dichloromethane and water are added to carry out extraction; organic phases are combined, dried, filtered, and the solvent is removed under reduced pressure; and the product is separated and purified; the fluorescent probe is basically non-fluorescent by itself, releases bright fluorescence after reacting with lipase, and can realize rapid detection of bacteria by using the characteristics that most bacteria secrete lipase in the growth and reproduction process.
