[0001] The present application belongs to the technical field of cultivation of Phellinus baumii, and particularly relates to a fermentation material Phellinus baumii cultivation method and culture medium bag. BACKGROUND

[0002] In the existing Phellinus baumii cultivation, a commonly used culture material treatment method is to directly produce a fungus stick through high-pressure sterilization without fermentation, that is, after the culture material is mixed in a certain proportion, the culture material is directly sterilized through a high-pressure sterilization device without stacking and fermentation, and after sterilization, the culture material is cooled and inoculated with Phellinus baumii spores, and then the culture material is loaded into a fungus bag for fungus growth. The existing technology has the following disadvantages: 1. High energy consumption, high equipment and operation cost, and increased cultivation cost; 2. The culture material is not fermented, macromolecular substances such as cellulose are not decomposed, and nutrients are not easily absorbed by mycelium, resulting in slow fungus growth, sparse mycelium, and weak vitality; 3. The microecology of the culture material after sterilization is single, mycelium is difficult to colonize, and the risk of contamination by miscellaneous bacteria is high; 4. The proportion of traditional formula mulberry branch chips is low, and the unique nutrients of the mulberry branch chips are not fully utilized, which affects the quality of Phellinus baumii; and 5. The fungus stick has poor air permeability, which limits the growth space of mycelium. SUMMARY

[0003] The present application belongs to the technical field of cultivation of Phellinus baumii, and particularly relates to a fermentation material Phellinus baumii cultivation method and culture medium bag. The fermentation material Phellinus baumii cultivation method and culture medium bag have low cost, efficient nutrient utilization, good air permeability, accelerated fungus growth, enhanced mycelium vitality, and reduced contamination rate, and can effectively improve the quality of fruiting bodies.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: A fermentation material Phellinus baumii cultivation method is designed, and the method specifically includes the following steps: Step 1, culture material preparation: mulberry branch chips 80%, cotton seed hulls 17%, lime 2%, and gypsum 1% are weighed according to the percentage by weight, and then mixed uniformly; Step 2, stacking and fermentation: the mixed culture material is stacked, the pile temperature is controlled at 55-65℃, and the culture material is fermented for 5-7 days with 2-3 times of pile turning until the culture material is rotten and odorless; Step 3, spore mixing: the fermentation material is cooled to room temperature, and then 70% of the culture material is mixed with 30% of Phellinus baumii spores according to the weight ratio to obtain fermentation Phellinus baumii culture medium material; Step 4, bagging and fungus growth: the fermentation Phellinus baumii culture medium material is filled into a breathable bag to obtain a culture medium bag, and the culture medium bag is cultured at 20-25℃ in the dark with ventilation, a small amount of mycelium is formed, the padding material in the culture medium bag is removed, a breathable growth groove is formed on the surface of the fermentation material mulberry fungus stick, and the culture is continued until the fungus bag is fully covered with mycelium; Step 5, fruiting management: after the fungus bag is fully covered with mycelium, the packaging material of the culture medium bag is removed, the fermentation material mulberry fungus stick is moved to a mushroom shed, and the fruiting bodies are harvested when the fruiting bodies are mature.

[0005] To solve the above-mentioned technical problems, the present invention also proposes a culture medium package for fermented mulberry fungus cultivation, which is used in the fermented mulberry fungus cultivation method. The package includes a cylindrical bag, and the inner side of the package is evenly distributed with sealed air bladder strips, and long strips of padding material are arranged between the air bladder strips. The packaging material has ventilation holes evenly distributed along its length, corresponding to the position of the padding material. The packaging material is filled with fermented Sanghuang culture medium to form fermented Sanghuang fungus sticks; After the padding material is removed from the packaging material, a breathable growth groove for mycelial growth is formed on the fermented mulberry fungus sticks. The packaging material has a lower cover and an upper cover fixed at both ends, respectively.

[0006] Furthermore, one side of the packaging material is provided with an openable zipper along its length.

[0007] Furthermore, the inner circumferential surfaces of the lower cover and the upper cover are provided with insertion holes that are adapted to the diameter of the end of the pad material.

[0008] Furthermore, the upper cover is provided with an injection hole, and the injection hole is provided with a suitable cap.

[0009] The present invention proposes a fermented substrate cultivation method and culture medium package for Phellinus linteus, which has the following advantages: the invention reduces costs, utilizes nutrients efficiently, has good air permeability, accelerates mycelial growth, enhances mycelial vitality, reduces contamination rate, and can effectively improve the quality of fruiting bodies. Specifically: 1) Cost reduction: Fermentation can replace autoclaving, and after experiments, energy consumption and equipment costs can be reduced by more than 30%.

[0019] The structural features of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] This embodiment provides a method for cultivating Phellinus linteus using fermented substrate, which specifically includes the following steps: Step 1, Preparation of culture medium: Weigh out 80% mulberry branch scraps, 17% cottonseed hulls, 2% lime, and 1% gypsum by weight percentage, and mix them evenly; Step 2, composting and fermentation: Compost the mixed culture medium, control the pile temperature at 55-65℃, ferment for 5-7 days, turn the pile 2-3 times, until it is fully decomposed and odorless; Step 3, Mixing the inoculum: Cool the fermentation material to room temperature, and mix 70% of the culture material with 30% of the Phellinus linteus inoculum at a weight ratio to obtain the fermented Phellinus linteus culture medium. Step 4, bagging and mycelium growth: Fill the fermented Sanghuang culture medium into a breathable bag to obtain a culture medium package. Incubate at 20-25℃ in the dark and keep it ventilated. After a small amount of mycelium has formed, remove the pad material 6 from the culture medium package and form a breathable growth groove 8 on the surface of the fermented Sanghuang mycelium stick 7. Continue to cultivate until the mycelium is fully grown in the bag. Step 5, Mushroom Management: After the mushroom bags are fully grown, remove the packaging material 1 of the culture medium bag and transfer the fermented mulberry mushroom sticks 7 into the mushroom shed until the fruiting bodies mature and are harvested.

[0021] The method for cultivating Phellinus linteus using fermented substrate of this invention, compared with traditional cultivation methods, offers the following advantages: Cost reduction: Fermentation replaces high-pressure sterilization, reducing energy consumption and equipment costs by over 30%; Highly efficient nutrient utilization: Fermentation decomposes macromolecular substances, combined with a high proportion of mulberry branch fragments, increasing nutrient absorption rate by 25%; Accelerated mycelial growth: A 30% inoculum ratio and suitable conditions shorten the mycelial growth cycle by 10-15 days; Enhanced mycelial vitality: The fermented substrate maintains a balanced microecology, promoting aeration and resulting in denser, stronger mycelia, increasing vitality by 20%; Reduced contamination rate: Fermentation inhibits unwanted microorganisms, reducing the contamination rate by 15-20%; Improved quality: Increased utilization of unique components from mulberry branches, increasing the content of effective components in fruiting bodies by 10-15%, and increasing yield by 10-20%.

[0022] See Figures 1-4 To prepare the fermented substrate Sanghuang mycelium stick 7, this embodiment also provides a culture medium bag for fermented substrate Sanghuang cultivation, which is used in the fermented substrate Sanghuang cultivation method. It includes a bag material 1, which is a PVC bag. The bag material 1 is a cylindrical bag. The inner side of the bag material 1 is evenly distributed with sealed air bladder strips 12. A long strip of pad material 6 is placed between the air bladder strips 12. The pad material 6 is a long cylindrical body. The diameter of the pad material 6 is adapted to the gap size between the air bladder strips 12. One side of the bag material 1 is provided with an openable zipper strip 2 along the length direction. By setting the zipper strip 2, the cylindrical bag material 1 can be unfolded. After unfolding, the bag material 1 can be easily removed from the culture medium bag. After disinfection, it can be reused. On the one hand, it can avoid the pollution of the environment by disposable plastic bags. On the other hand, it can reduce the manufacturing cost of the bags.

[0023] Ventilation holes 11 are evenly distributed along the length of the packaging material 1 corresponding to the position of the padding material 6. After the packaging material 1 is filled with fermented Sanghuang culture medium, it forms fermented Sanghuang mycelium sticks 7. The ventilation holes 11 are used to ventilate the fermented Sanghuang mycelium sticks 7 inside the bag.

[0024] After the substrate 6 is removed from the packaging material 1, a breathable growth groove 8 is formed on the fermented substrate Huangsang mycelium stick 7 for mycelial growth. The air vents 11 can communicate with the breathable growth groove 8. The breathable growth groove 8 is distributed in a long strip on the surface of the fermented substrate Huangsang mycelium stick 7, which can partially separate the mycelium bag from the fermented substrate Huangsang mycelium stick 7. On the one hand, it increases the air volume in the mycelium bag, and on the other hand, it can provide more growth space for mycelial growth, avoid the mycelium bag restricting mycelial growth, and make the mycelium grow thicker.

[0025] To seal the ends of the packaging material 1 that form the fungal bag, a lower cover 3 and an upper cover 4 are fixed at both ends of the packaging material 1, respectively. To fix the lower cover 3 and the upper cover 4, insertion holes 31 that are adapted to the diameter of the end of the pad material 6 are provided on the inner circumferential direction of the lower cover 3 and the upper cover 4. Before filling, the two ends of the pad material 6 can be connected between the lower cover 3 and the upper cover 4 to form a support, which is more conducive to filling and can improve the support of the fermentation material Huangsang fungus sticks 7. During filling, the pressure can be increased, making the fermentation material Huangsang fungus sticks 7 more compact. In order to facilitate the filling of the fermentation Huangsang culture medium, an injection hole 41 is provided on the upper cover 4. An appropriate cap 5 is provided on the injection hole 41. After the fermentation Huangsang culture medium is filled, the injection hole 41 is sealed by the cap 5.

[0026] Specifically, in use, first align the two ends of the substrate 6 with the insertion holes 31 on the lower cover 3 and upper cover 4, and insert them to form a support. Then, wrap the packaging material 1 around the outside of the substrate 6, seal the chain 2, so that the packaging material 1 forms a cylindrical fungal bag, and embed both ends of the packaging material 1 into the lower cover 3 and upper cover 4. Then, fill the fungal bag with fermentation culture medium through the injection hole 41 and compact it. After completion, place the culture medium bag in a dark place at 20-25℃ and keep it ventilated. After a small amount of mycelium has formed... Under the influence of a small amount of mycelium, the fermented substrate Huangsang mulberry spawn 7 forms a whole and will not easily fall apart. At this time, remove the lower cover 3 and upper cover 4 at both ends of the fermented substrate Huangsang mulberry spawn 7, and pull out the substrate 6. A breathable growth groove 8 is formed on the surface of the fermented substrate Huangsang mulberry spawn 7 along its length. Continue to cultivate until the spawn bag is full of mycelium. After the spawn bag is full, pull open the chain 2, remove the packaging material 1 of the culture medium bag, and transfer the fermented substrate Huangsang mulberry spawn 7 into the mushroom shed. The removed packaging material 1 is disinfected and sterilized for the next use.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
