The application discloses a kind of whole-process tracking management methods and systems for Epimedium sagittatum plantation, it is related to agricultural product management technical field, comprising: according to planting plot and planting time, generating planting batch number, constructing basic traceability file, based on agricultural key control point, obtain planting monitoring data, and association binding, set threshold to growth stage plant representation data, compare set threshold and planting node process file abnormal node, integrate planting node process file and abnormal disposal file, generate harvesting suitability score to determine planting batch, according to executable batch harvesting confirmation voucher, verify planting batch number, record postpartum quality data, input to planting node process file, and construct planting whole-process traceability file.The application is associated with binding by setting agricultural key control point and planting batch number, realizes the automatic acquisition of Epimedium sagittatum planting process data and whole-node traceability.

This invention relates to the field of quality information traceability technology, and discloses a method and system for tracing the quality information of Epimedium sagittatum. The method includes acquiring basic data and planting parameters of the current batch of Epimedium sagittatum seedlings; processing the basic data and planting parameters using a hash algorithm to generate a basic query code; using the basic query code as a parent node and combining it with growth data to generate a growth code; generating a raw material code for the current batch by combining it with process parameters, and associating the raw material code with the growth code; generating an outbound code using a timestamp and the raw material code; generating auxiliary material codes for auxiliary materials involved in deep processing, associating the auxiliary material codes with the outbound code, and generating a product code by combining it with production parameters. This invention facilitates rapid identification of the source and responsible link of quality fluctuations, sets incremental collection frequencies and differentiated collection indicators for different stages, improves the sufficiency of quality assessment basis, and reduces the risk of tampering or falsification during the process.

This invention discloses a flavonol glycosyltransferase EsGT_F from *Epimedium sagittatum* and its applications. The EsGT_F gene provided by this invention is 1398 bp in length, encoding 466 amino acids. After cloning the *Epimedium sagittatum* flavonol glycosyltransferase gene EsGT_F, a prokaryotic expression system was constructed. The expressed protein exhibits flavonol glycosyltransferase activity, catalyzing the conversion of cymosin I to icariin. The *Epimedium sagittatum* flavonol glycosyltransferase and its encoding gene provided by this invention offer important gene elements and corresponding technical methods for the microbial cell factory production of the active ingredients of *Epimedium*, and have significant application prospects.
