This invention discloses a multi-target synergistic preservation method for fruits and vegetables based on the active ingredients of Torreya grandis aril, belonging to the field of fruit and vegetable preservation technology. The method includes the following steps: Step 1: Using Torreya grandis aril as raw material, Torreya grandis aril essential oil is extracted by steam distillation. This multi-target synergistic preservation method for fruits and vegetables based on the active ingredients of Torreya grandis aril combines four active ingredients—3-carene, D-limonene, δ-juniperol, and δ-juniperene—from the Torreya grandis aril essential oil with chitosan to construct an integrated synergistic preservation system of "antioxidant—enzyme inhibition—film protection—antibacterial action." This system protects the integrity of fruit cell membranes and delays softening and water loss, thereby overcoming the shortcomings of existing technologies that are single-function and unstable in effect. It achieves precise, multi-target intervention across the entire chain of postharvest physiological decline in perishable fruits and vegetables.

The invention discloses an environment-friendly multifunctional herbicide and a preparation method thereof. The environment-friendly multifunctional herbicide comprises red oil and / or acid water separated during synthesis of 1, 8-terpin from turpentine; the red oil is pinene and isomerization or addition byproducts thereof, and comprises one or more of tricyclene, camphene, carene, limonene, cymene, terpinene, isoterpinene, phellandrene, 1, 4-cineole, 1, 8-cineole, fenchene, fenchol, isoborneol, borneol, 4-terpilenol, beta-terpilenol, alpha-terpilenol and gamma-terpilenol. Compared with turpentine, the herbicide has a broad-spectrum and efficient killing effect and also has killing and repelling effects on pests, and meanwhile, the compounds are easy to naturally degrade in the environment and are non-toxic to human.

The invention provides a slow-release diaphorina citri attractant which comprises an attracting part and a slow-release part, wherein the luring part is prepared from the following components in percentage by mass: 1 to 5 percent of p-cymene, 50 to 80 percent of citral, 1 to 5 percent of gamma-terpinene, 1 to 5 percent of linalool, 10 to 20 percent of gamma-terpinene, 1 to 5 percent of carene, 1 to 5 percent of terpinene, 1 to 5 percent of cis-3-hexenol, 1 to 5 percent of n-decanoic acid, 1 to 3 percent of methyl anthranilate and 1 to 2 percent of pyrazine; the slow-release part comprises an adsorption slow-release component and an azeotropic slow-release component. The invention further provides application of the slow-release diaphorina citri attractant, and the slow-release diaphorina citri attractant is used for trapping and killing diaphorina citri. The invention further provides a using method of the slow-release diaphorina citri attractant. The azeotropic slow-release component and the adsorption slow-release component are combined, so that the volatilization efficiency of the luring part is reduced, the stable volatilization speed can be better maintained, the high attractant concentration is maintained within two to three weeks in cooperation with the diaphorina citri outbreak period and the yellow plate effective adhesion time, and the better pest killing effect is achieved.

The application discloses a kind of o-carborane-thioxanthene fluorescent compounds, fluorescent sensing film and its preparation method and the application of detecting terpene, belong to fluorescent sensing material technical field.The o-carborane of the present application is connected with thioxanthene by covalent bond, and a class of D-A type fluorescent compounds is constructed, wherein thioxanthene is used as electron donor to provide fluorescent emission capacity, and o-carborane is used as electron acceptor to give molecular three-dimensional cage-like stereostructure, which effectively inhibits the quenching effect caused by aggregation, so that the material keeps high fluorescence quantum yield in solid state.The fluorescent compound is loaded on the surface of matrix to prepare fluorescent sensing film, and the film has fluorescent response to a variety of terpene volatile organic compounds such as alpha-pinene, beta-pinene, limonene, 3-carene and camphene, wherein the response to alpha-pinene is the most sensitive, has the advantages of fast response speed, good reversibility, excellent cycle stability and the like, and is suitable for forest pest warning, ecological environment monitoring and volatile biomarker detection and other fields.
