The application discloses a kind of Fusarium tricinctum and application, belong to the field of agricultural microorganism, the preservation number of this Fusarium tricinctum is CGMCC No.40248.The application obtains a strain of biocontrol weed strain from the collection and purification of the diseased weed disease sample in different areas of Qinghai province, carries out weed pathogenicity determination, crop safety determination, strain classification and identification, and optimal carbon and nitrogen source screening.The results show that: the application obtains a strain with weed inhibition activity-Fusarium tricinctum, which provides basis and basis for the utilization of weed pathogenic fungal resources and the research of microbial herbicide, and provides a safe, efficient and pollution-free microbial herbicide for weed control in farmland of Qinghai province.

The present application relates to the technical field of remote sensing image processing and ecological monitoring, and provides a grassland mushroom ring remote sensing identification method and system based on multispectral threshold screening and geometric constraint, computer equipment, computer readable storage medium and computer program product, the identification method comprising: S1, multispectral remote sensing image acquisition and preprocessing; S2, vegetation index construction and ring band feature enhancement; S3, adaptive threshold screening to generate candidate binary graph; S4, morphological arc breaking repair and connected domain candidate region extraction; S5, geometric constraint fitting and parameter extraction; S6, false target suppression and consistency verification; S7, identification result output. The identification method provided by the present application automatically identifies the mushroom ring target in the remote sensing image and extracts the structured parameters such as center coordinates, radius and ring width, effectively enhances the ring band features of the mushroom ring and suppresses the false detection caused by complex background interference, improves the identification accuracy and reliability, and the obtained results can be used for fungal resource investigation and grassland ecological monitoring.
