The invention discloses a method for distinguishing clematis palustris from other clematis plants and application of the method. The method for distinguishing the clematis from the other clematis plants comprises the following steps: detecting whether the genotype of 201st deoxyribonucleotide in a sequence 1 of a plant to be detected is an AA genotype or a CC genotype by adopting a primer pair consisting of a single-stranded DNA (Deoxyribonucleic Acid) shown in a sequence 2 and a single-stranded DNA shown in a sequence 3; the to-be-detected plant is clematis hispida; if the genotype of the plant to be detected is AA genotype, the plant to be detected is other clematis plants. Experiments prove that the method provided by the invention can be used for effectively distinguishing the clematis palustris from other 14 clematis plants, and an important tool is provided for quickly and accurately identifying the clematis palustris in the seedling stage.

This invention discloses tree fern. AspiMYB5 The application of genes in regulating the biosynthesis of tree fern phenols belongs to the field of genetic engineering technology, which involves regulating the biosynthesis of tree fern phenols within plants. AspiMYB5 The expression level of the gene, thereby regulating the key enzyme gene of tree fern phenol. AspiPKS6 The expression of [a specific enzyme] and the synthesis of tree fern phenol. This invention uses a yeast library screening method to screen genes affecting key enzymes. AspiPKS6 Expressed transcription factors AspiMYB5 The results were verified using yeast single-hybrid technology (Y1H) and electrophoretic mobility variation analysis (EMSA). AspiMYB5 and AspiPKS6 The promoter exhibits direct physical binding in vitro. Dual-luciferase reporter gene assays further demonstrate that... AspiMYB5 and AspiPKS6 When the promoter is co-expressed, the fluorescence signal intensity is significantly reduced, further confirming... AspiMYB5 It can inhibit AspiPKS6 AspiMYB5 Promoter activity. This invention not only improves the theoretical research on the biosynthetic pathway of tree fern phenols, but also provides key target genes and technical support for regulating the content of secondary metabolites in rare plants through genetic improvement.

The invention discloses a traditional Chinese medicine active extract for preventing and treating asparagus stem blight and a preparation method thereof, and belongs to the technical field of crop planting, the traditional Chinese medicine active extract is prepared from the following raw materials in parts by weight: 20-30 parts of sweet wormwood, 15-20 parts of radix scutellariae, 15-25 parts of rhizoma smilacis glabrae, 8-12 parts of radix sophorae flavescentis, 9-17 parts of radix stephaniae tetrandrae, 2-5 parts of perilla frutescens, 10-15 parts of folium isatidis, 8-10 parts of cyrtomium fortunei and 3-5 parts of indigo naturalis. The preparation method comprises the following steps: crushing the raw materials, uniformly mixing, adding an ethanol solution, carrying out ultrasonic extraction, carrying out aerobic fermentation on the obtained extracting solution, finally carrying out evaporation concentration on the obtained fermentation solution, and carrying out spray drying to obtain the traditional Chinese medicine active extract. According to the invention, various Chinese herbal medicine raw materials are carefully selected, the ratio is optimized, and the processes of crushing, mixing, ethanol ultrasonic extraction, aerobic fermentation, spray drying and the like are combined, so that active components are effectively extracted. An efficient and natural solution is provided for preventing and treating the asparagus stem blight.

The invention provides a method and a system for intelligently monitoring and evaluating the growth state of polystichum crassipes, and belongs to the technical field of computer vision, and the method comprises the following steps: inputting an image of polystichum crassipes into an improved UNet3 + model; the improved UNet3 + model comprises an encoder, a dual-path context attention module and a decoder; performing feature extraction on the image through an encoder to obtain a feature map; respectively generating a global key-value vector and a local key-value vector of the feature map through a dual-path context attention module, and generating a fusion feature map based on the global key-value vector, the local key-value vector and an attention mechanism; generating an edge segmentation result of the polystichum crassifolium based on the fused feature map through a decoder; and determining the growth stage of the polystichum crassifolium based on an edge segmentation result. According to the method, the dual-path context attention module is introduced into the UNet3 + model, so that a more robust and accurate edge segmentation result can be generated, and the judgment accuracy of the growth stage of the rhizomatopteris crassipes is improved.

The application belongs to the field of traditional Chinese medicine preparations, and particularly relates to an oral liquid capable of promoting easy absorption of qi and blood tonification and a preparation process thereof. The preparation process comprises the following steps: preparation of an absorption promoting agent, preparation of a stabilizing and compatible agent, steaming and extraction of traditional Chinese medicinal materials, and preparation of the oral liquid. The absorption promoting agent is prepared by enzymolysis of mixed slurry of Adiantum capillus-veneris flowers and liquidambar resin using cellulose-pectin complex enzyme, and the absorption promoting agent is obtained by freeze-drying of the prepared liquidambar resin-Adiantum capillus-veneris enzymolysis liquid. The absorption promoting agent is added in the preparation process of the oral liquid, so that the absorption rate of effective components of Lycium chinense, Poria cocos, jujube and longan aril in the intestinal tract is improved, and the effect of the oral liquid capable of promoting easy absorption of qi and blood tonification on blood and qi tonification of human bodies is improved.

The application belongs to the technical field of cosmetics, and discloses a fucoidan composition, a preparation method and application thereof. The fucoidan composition comprises adiantum capillus-veneris fucoidan, ralfsia dactylifera fucoidan and pseudochoricystis sp. fucoidan, and the mass ratio of the adiantum capillus-veneris fucoidan, the ralfsia dactylifera fucoidan and the pseudochoricystis sp. fucoidan is (1-2):(1-2):(1-2). The fucoidan composition is prepared by compounding specific adiantum capillus-veneris fucoidan, ralfsia dactylifera fucoidan and pseudochoricystis sp. fucoidan, and has excellent whitening, anti-wrinkle, moisturizing and antioxidant multiple effects through synergistic effect. When the fucoidan composition is applied to cosmetics, it has good formula adaptability, does not affect the exertion of the effects and the stability of the cosmetics.
