Rapid identification method for endophyte of paeonia lactiflora

The invention relates to the technical field of microorganisms, in particular to a method for quickly identifying endophytes of paeonia lactiflora. The method comprises the following steps: acquiring an endophyte image of paeonia lactiflora, preprocessing the image, and extracting feature parameters to construct a sample set; and constructing an identification model based on a Bi-LSTM network, carrying out model training, and preferably selecting the model with the highest identification accuracy as a rapid identification model of the endophyte of the paeonia lactiflora. According to the method, the endophyte of the paeonia lactiflora can be quickly and accurately identified under the condition of limited sample size, and compared with traditional strain identification, time and cost can be saved, and screening of the endophyte producing active substances is facilitated. 本发明涉及微生物技术领域，具体涉及一种芍药内生菌的快速识别方法。本发明方法包括以下步骤：采集芍药内生菌图像，对图像进行预处理，提取特征参数构建样本集；构建基于Bi-LSTM网络的识别模型，并进行模型训练，优选识别准确率最高的模型作为芍药内生菌的快速识别模型。本发明方法可在样本量有
