The present invention proposes a FVEP feature point detection method based on CAA-Net and LightGBM, comprising the following steps: S1, data preprocessing: standardize the FVEP signal, as the input of the neural network model; S2, feature point sequence generation: S2 ‑1, the position coordinates of possible feature points are selected through the CAA‑Net model, and the candidate feature points with low probability are filtered; S2‑2, the sequence of feature points to be selected is generated: if the points in the feature point set to be selected If it is not an extremum point, search in the range where the distance between the feature points in the feature point set to be selected is less than 2. If no extremum point is found, discard the point. If an extremum point is found, replace it to be selected feature points; then, generate a preliminary set of feature point sequences to be selected according to the exhaustive method; S3, feature point sequence selection, and obtain the optimal feature point sequence. The invention can quickly and effectively obtain the characteristic points of the FVEP waveform, so as to perform clinical analysis on the patient's condition.

The invention provides a method for grafting Ilex sp. by taking Ilex dabieshanensis as a stock.
