The utility model relates to the technical field of extraction devices, and discloses a Ixeris denticulata flavone extraction device which comprises an extraction tank and a top cover arranged on the top surface of the extraction tank, a feed pipe is fixedly connected to the top cover in a penetrating mode, and a liquid inlet pipe and a discharge pipe are fixedly connected to the side wall of the extraction tank in a penetrating mode. A plurality of ultrasonic emission heads are fixedly connected to the bottom surface of the top cover, a porous sound absorption plate is fixedly arranged on the inner wall of the extraction tank, a plurality of heat conduction assemblies are symmetrically and fixedly connected to the side wall of the porous sound absorption plate, a filter plate is fixedly connected to the bottom surface of the porous sound absorption plate, and a plurality of driving assemblies are fixedly connected to the bottom surface of the filter plate. Heat is conducted out in time through the heat conduction assembly, too high temperature caused by continuous temperature rise is avoided, the driving assembly and the filter plate are arranged, when certain extraction time is up, the filter plate is communicated up and down, flavonoid substance extraction liquid of the ixeris denticulata is filtered through the filter holes and flows below the filter plate, and the extraction efficiency is improved. The damage to the effective components of the extract due to overlong heating time is prevented.

The invention discloses a cladosporium endophytic fungus YT15-1 and application thereof, and belongs to the technical field of microorganisms. The cladosporium endophytic fungus YT15-1 is separated from the root system of sonchus oleraceus, is classified and named as Saroocladium strictum YT15-1, is preserved in the China Center for Type Culture Collection (CCTCC), and has the preservation number of CCTCC NO: M 20252189. The YT15-1 and rice are co-cultured, so that the YT15-1 can be colonized in the root tissue of the rice, and the resistance of the rice to salt stress in the seedling stage can be effectively enhanced. Under the condition of high salt stress, compared with a control group, the stem and leaf height, the root length and the stem and leaf fresh weight of a YT15-1 strain treatment group are respectively increased by 75.54%, 214.71% and 52.63%.

The application discloses a Talaromyces purpureogenus and application thereof in weeding, and belongs to the technical field of bioengineering and weeding, wherein the Talaromyces purpureogenus is named as CY-1, is preserved in the China General Microbiological Culture Collection Center, and has a preservation date of May 23, 2022 and a preservation number of CGMCC No.40203. Metabolic products of the Talaromyces purpureogenus CY-1 in the application can effectively inhibit broadleaf weeds such as amaranthus retroflexus, alternanthera philoxeroides, xanthium, chenopodium album, solanum nigrum, bidens pilosa, comphre, sonchus oleraceus, pteris cretica, medicago sativa, ipomoea hederifolia, rumex patientia, galium aparine, abutilon theophrasti, portulaca oleracea, leonurus japonicus, veronica anagallis, and aster spathulifolius, and the Talaromyces purpureogenus CY-1 is green and efficient in weeding, and has a wide application prospect in weeding.

This application relates to the field of image data processing technology, specifically to a visual detection method and system for crop growth environments. The method includes: acquiring standard *Sonchus oleraceus* images from multiple angles; for each angle, constructing a yellow distribution factor for the standard *Sonchus oleraceus* image; constructing a segmentation factor for the standard *Sonchus oleraceus* image, adaptively determining the number of superpixel blocks to obtain the superpixel blocks corresponding to the standard *Sonchus oleraceus* image; constructing petal saliency values ​​for each superpixel block; constructing *Sonchus oleraceus* saliency factors for each superpixel block; determining salient regions based on the *Sonchus oleraceus* saliency factors; matching salient feature points in the image to be detected with those in the standard *Sonchus oleraceus* image; and obtaining the detection result of the image to be detected based on the matching results. This application improves the accuracy of detecting *Sonchus oleraceus* in the corn seedling growth environment by analyzing the unique characteristics of *Sonchus oleraceus* in the corn seedling growth environment.

The invention discloses a method for extracting luteoloside from sonchus oleraceus and application, and belongs to the technical field of biological medicine. According to the method, a response surface method is utilized to optimize the extraction process of the flavone substances in the sonchus oleraceus in the Uygur autonomous region of Xinjiang, and the optimal process conditions are as follows: the ethanol concentration is 60%, the extraction time is 30 minutes, the material-liquid ratio is 1: 91 g / mL, and the extraction temperature is 65 DEG C. Under the process conditions, the flavone extraction rate is 10.76%. 44.06 [mu] g / g of luteoloside is finally obtained. The content of inflammatory factors of the luteoloside on the rabbit colonic epithelial cell inflammation induced by lipopolysaccharide (LPS) is detected by utilizing ELISA, and the result shows that the luteoloside inhibits the rabbit colonic epithelial cell inflammation induced by the LPS by inhibiting release of the inflammatory factors TNF-alpha, IL-1beta and IL-6.
