The invention discloses a method for interplanting and intercropping pheretima and centella asiatica, and relates to the technical field of Chinese herbal medicine planting and breeding combination. The specific interplanting and intercropping method comprises the following steps: (1) selecting a planting and breeding area; (2) transplanting centella asiatica; (3) putting pheretima seedlings; (4) planting and breeding management: applying compound microorganisms to roots in the vigorous growth period of centella asiatica, and then performing cyclic illumination stress treatment; and (5) harvesting centella asiatica and pheretima. According to the method, the problems that the utilization rate and the output rate of land resources of traditional Chinese medicinal materials are low and active ingredients for artificially planting centella asiatica are not high enough are solved by adopting a centella asiatica and pheretima interplanting intercropping mode and adopting the technical means of compound microorganism root stimulation, circulating illumination stress treatment and the like; double benefits and high quality of the centella asiatica and the pheretima are achieved, and the method can be used for standardized and large-scale cultivation of the centella asiatica and the pheretima.

This invention relates to a method for preparing a fern-like beverage. Fern-like fern (Pteris tigrinosa) is a plant belonging to the genus *Pteris* in the family Pteridaceae. The young leaves of *Pteris tigrinosa* are edible because they have a refreshing cucumber-like aroma, hence the common name "cucumber-scented fern." The purpose of this invention is to provide a method for preparing a high-quality fern-like fern beverage, taking advantage of the fern's rich content of various beneficial components and its cucumber-like aroma. The preparation method involves adding taste-adjusting ingredients to water and mixing thoroughly. Cleaned young fern shoots, processed to a size of 1 mm to 10 mm, are then added to the solution. The mixture is mixed thoroughly, bottled, and the bottled fern-like fern beverage is sterilized in a water bath at 70℃-100℃ for 30 minutes to obtain the finished product. This invention is beneficial for the development and utilization of fern-like fern in beverages.

The invention provides an assembled and annotated chloroplast genome of euphorbia splendens, and relates to the fields of molecular biology and plant genetics. The chloroplast genome of the pteris amurensis is a single cyclic molecule; the total length of the chloroplast genome of the psidium aquilinum is 149180bp; the nucleotide sequence of the chloroplast genome of the pteris amurensis is as shown in SEQ ID NO. 1; the GC content of the chloroplast genome of the pteris amurensis is 43.14%; the pteridium aquilinum chloroplast genome provided by the invention enriches a pteridium gene database, lays a foundation for exploring pteridium aquilinum evolution history and an adaptation mechanism of pteridium aquilinum to environmental stress, decrypts genetic codes of pteridium aquilinum from a molecular level, and is applied to biodiversity protection, plant ecological restoration and gardening.

The present invention provides a cultivation method for Pteris racemosa. The cultivation method involves cultivating Pteris racemosa in a water aquaculture area in different zones. Within the water aquaculture area, an area 0.2 to 0.4 meters above the water surface serves as a first zone, and other zones within the water aquaculture area serve as a second zone. In the first zone, the Pteris racemosa in the zone is secured by hanging cultivation: multiple hanging bases are secured on a support spanning the water aquaculture area, the hanging bases are sunk into the first zone, the Pteris racemosa are evenly suspended on the hanging bases, and first air stones are secured between the hanging bases. In the second zone, the Pteris racemosa in the zone is secured by using a support net frame cultivation method: the support net frame is placed at the bottom of the water aquaculture area, the support is fully covered with net frames, the Pteris racemosa are evenly secured on the net frames, and second air stones are secured to the net frames. The cultivation method provided by the present invention results in a higher yield of Pteris racemosa and better cultivation results.

The present invention provides an active polysaccharide from the genus Pteris serrata, a preparation method, and an application thereof. The polysaccharide comprises mannose, rhamnose, glucuronic acid, glucose, galactose, xylose, arabinose, and fucose in a molar ratio of (9.6-9.8): (8.5-8.7): (3.1-3.3): (37.0-37.2): (21.3-21.5): (4.4-4.6): (7.2-7.4): (5.8-6.0). The active polysaccharide prepared by the present invention can increase the phagocytic activity of RAW264.7 cells, increase the serum IgM level of immunosuppressed mice, improve the spleen tissue morphology of immunosuppressed mice, increase the organ index of immunosuppressed mice, and increase the proportion of T lymphocytes in the spleen of immunosuppressed mice, thereby significantly improving immunity.

This invention discloses a method for breaking the cell wall of Pteris vittata spore powder, comprising grinding and breaking the cell wall: placing Pteris vittata spore powder in a grinding tube, and mixing it with a material-to-liquid ratio of 1:(80-90) g / mL. ‑1 Distilled water was added in a specific ratio, and the grinding tube containing the *Pteris vittata* spore powder and distilled water was placed in a tissue homogenizer. The homogenizer was turned on to lower the temperature to below 4°C, and then the cells were ground to break the cell walls, resulting in a suspension of broken *Pteris vittata* spore powder. This cell wall breaking method can break the outer shell of *Pteris vittata* spores, achieving a cell wall breaking rate of over 95.15%, while greatly preserving the active ingredients in the broken *Pteris vittata* spore powder. This invention also confirms that *Pteris vittata* spores have the same efficacy as the whole *Pteris vittata* herb extract and are an important component of *Pteris vittata* medicinal materials. This invention also discloses a *Pteris vittata* spore powder and its uses.

The invention provides a cultivation method for improving heat resistance of heuchera micrantha, and relates to the technical field of gardening flower cultivation. The method comprises the following steps: planting gynostemma pentaphyllum, heuchera micrantha and passionflower in a layered manner, hanging new pteris fern potted plants on a shed frame, and spraying rare earth cerium and a potassium silicate solution. Gynostemma pentaphyllum, heuchera micrantha and passionflower are planted in a layered manner, and new pteris fern potted plants are hung on a shed frame, so that the soil porosity and moisture content of a planting area can be improved, the surface temperature of the planting area in summer is reduced, and the output value per unit area is increased; rare earth cerium and a potassium silicate solution are sprayed on the basis of layered planting, so that the relative conductivity and malondialdehyde content of heuchera micrantha leaves can be reduced, the chlorophyll content can be increased, Pn and Tr of the heuchera micrantha leaves can be increased, the average activity of SOD, POD and CAT of the leaves can be increased, and the survival rate can be increased.
