Description

Technical Field

[0001] This invention belongs to the field of mushroom conservation technology, specifically a method for protecting the wild population of bright red lactus mushrooms. Background Technology

[0002] Lactarius vividus XHWang, Nuytinck & Verbeken, is a fungus belonging to the genus Lactarius in the family Russulaceae of the class Agaricaceae in the phylum Basidiomycota. It commonly forms ectomycorrhizae with trees such as Masson pine, pine, and spruce. It has a tender texture, delicious flavor, and is rich in nutrients, possessing high edible and medicinal value. However, due to its unique growth conditions, nutritional methods, and fruiting body differentiation requirements, it cannot yet be artificially domesticated and cultivated.

[0003] The peak season for harvesting bright red lactus mushrooms is from May to October each year. In recent years, with the continuous improvement of people's living standards and material needs, the over-harvesting of bright red lactus mushrooms and the destruction of their growing environment have led to a rapid decline in the wild population and distribution area of ​​bright red lactus mushrooms. In addition, the imperfect harvesting methods and management of wild harvesting sites make the protection of the wild population of bright red lactus mushrooms urgent.

[0004] Therefore, it is necessary to provide a method for protecting the wild population of *Lactarius deliciosus* that can be harvested by tearing instead of cutting.

[0005] Due to the unique nutritional and developmental characteristics of the mycorrhizae of *Lactarius deliciosus*, its spore propagation is extremely difficult. Liquid spawn, however, offers advantages such as simple preparation, short production cycle, low production cost, and stable spore quality, making it an ideal choice for edible mushroom spore propagation. Patent application CN202010281748.9 discloses a liquid spawn culture medium formula and method for preparing *Lactarius deliciosus*. The formula includes pine needles, sucrose, malt extract, peptone, citric acid, magnesium sulfate, and vitamin B1, prepared in the following weight ratios: 1.0%-2.0% : 3.0%-4.0% : 0.05%-0.15% : 0.2%-0.4% : 0.01%-0.03% : 0.005%-0.015% : 0.00125%-0.00375%. The advantages of this culture medium are: spore propagation only requires static incubation and does not require aeration equipment, simplifying the spawn production process. The liquid spawn of *Lactarius deliciosus* cultivated using this method exhibits flocculent mycelium and rapid growth, covering the bottom of a 650ml tissue culture bottle within 40 days, effectively shortening the cultivation cycle of the original *Lactarius deliciosus* spawn. The amplified mycelium demonstrates strong resistance to contamination, reducing the contamination rate by 40% compared to the control. The mycelium is dense and brightly colored, resulting in a 49.85% increase in yield compared to the control. This patent application pertains to the formulation of the liquid spawn culture medium and the preparation method of the liquid spawn for *Lactarius deliciosus*.

[0006] In addition, the literature “Improvement and Optimization of Mother Culture Medium for Lactarius Brilliantus” (Han Yu, Wu Yao, Jie Chunyu, et al., Central South Agricultural Science and Technology, 2024, 45(3): 27-30) disclosed that soybean peptone promoted the mycelial growth rate of Lactarius Brilliantus by about 15% compared with ordinary animal-derived peptone.

[0007] In daily life, we can observe that fruits and vegetables that have been broken or torn can be preserved for a longer time under the same conditions compared to those cut with a knife. This is because the surface of the knife used to cut fruits and vegetables may be contaminated by microorganisms during the cutting process. The debris left by the knife on the cut surface may also react chemically with substances contained in the fruits and vegetables, enhancing the oxidation of the cut surface. In addition, breaking or tearing fruits and vegetables may leave more intact plant cell walls and cell membranes on the cut surface than cutting them, thereby reducing the rate at which external pathogens invade the cut surface and extending the shelf life of broken or torn fruits and vegetables. Summary of the Invention

[0008] To address the aforementioned problems, the present invention aims to provide a method for protecting the wild population of *Lactarius deliciosus*. This method utilizes a spring clip on the scissor arm of a mushroom protective harvester to cut a notch in the mushroom cap stem and then tear the *Lactarius deliciosus* from its mycelium along the notch. This extends the shelf life of the *Lactarius deliciosus*, reduces the probability of the remaining mycelium on the ground being infected by pathogens, and improves the regeneration efficiency of wild *Lactarius deliciosus*.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows: A method for protecting the wild population of *Lactarius deliciosus*:

[0010] Step 1, Site Selection: Select a site where brightly colored lactus mushrooms are evenly distributed and the site conditions are consistent;

[0011] Step 2, Protective Harvesting: When the product is mature, use a mushroom protective harvester to harvest the brightly colored latex mushrooms at the junction of the stipe and root of the fruiting body to avoid damaging the mycorrhizae of the brightly colored latex mushrooms during harvesting;

[0012] Step 3, Seed preservation and conservation: When picking brightly colored milk cap mushrooms, do not pick young or overripe mushrooms, and retain at least one brightly colored milk cap mushroom fruiting body in each mushroom bed. After picking brightly colored milk cap mushrooms, avoid trampling on and removing the base of the stem.

[0013] Step 4, pest control and propagation: Sprinkle natural insect repellent around the mushroom pond at the conservation site, and prepare a culture medium suitable for the absorption and utilization of bright red lactus to supplement the nutrients of the conservation site. Carry out daily management of the conservation site according to the conservation methods of bright red lactus.

[0014] The beneficial effects of the basic scheme are: 1. Selecting wild picking sites with uniform distribution of bright red lactus mushrooms and consistent site conditions helps with subsequent conservation and propagation management, improves the protection efficiency of wild bright red lactus mushroom populations, and also increases the regeneration yield of wild bright red lactus mushrooms.

[0015] 2. Use a mushroom protective harvester to harvest *Lactarius deliciosus* protectively. This allows smaller fruiting bodies to continue growing and leaves mycorrhizae in place, increasing the yield of wild *Lactarius deliciosus*. At the same time, the tearing and harvesting effect of the mushroom protective harvester can effectively extend the shelf life of the harvested *Lactarius deliciosus* and reduce the probability of mycorrhizae being infected by pathogens, thus improving the protection efficiency of wild *Lactarius deliciosus* populations.

[0016] 3. By preserving the mycorrhizae and overripe fruiting bodies of *Lactarius deliciosus* in their original locations, scientific seed preservation can be achieved for the conservation sites of *Lactarius deliciosus*, thereby increasing the yield of wild *Lactarius deliciosus*.

[0017] 4. By controlling pests and promoting propagation at conservation sites, on the one hand, pollution-free natural insect repellents are used to eliminate springtails that pose a significant threat to *Lactarius deliciosus*, and on the other hand, suitable culture media are applied. Through scientific conservation management of *Lactarius deliciosus* conservation sites, the yield of wild *Lactarius deliciosus* can be increased while protecting the wild population, thereby improving economic benefits.

[0018] Furthermore, the mushroom protective harvester includes scissors. Each scissor arm has a spring piece hinged to its upper front surface, parallel to the scissor arm. Each scissor arm has a fixed elevation plate extending vertically downwards from its front end. Each spring piece has a groove in the center of its upper surface, facing the cutting side. The spring pieces extend along the scissor arm. Two spring pieces near the scissor hinge are hinged together above the scissor hinge by a top hinge. The top hinge contains a magnetic component, and the scissor hinge contains an electromagnet. The magnetic field activated by the electromagnet repels the magnetic component. An electrical contact is fixedly connected to the inside of one handle, and an electrical arc strip is fixedly connected to the inside of the other handle. The electrical contact is located on the movement trajectory of the electrical arc strip. A battery is fixedly connected to the end of the handle furthest from the scissor hinge, and the battery is connected to the electrical contact, electrical arc strip, and electromagnet circuitry.

[0019] The beneficial effects of the basic scheme are as follows: the springs set on the upper surface of the scissor arms of the mushroom protective harvester can be driven by electromagnetic repulsion to bounce upwards near the end of the handle and tear off the cap stem along the notch cut by the scissor arms. This reduces the damage to the cell walls of the fungi at the top of the mycorrhizae, reduces the probability of mycorrhizae being infected by pathogens, reduces cell wall damage at the cap stem of the harvested brightly colored latex mushrooms, and extends the shelf life of the brightly colored latex mushrooms.

[0020] Furthermore, harvesting bright red milk mushrooms using a mushroom protective harvester involves: aligning the groove on the spring of the mushroom protective harvester with the stipe of the bright red milk mushroom fruiting body, placing the scissors horizontally close to the stipe, marking the required harvesting height with a leveling plate, and then simultaneously cutting vertically into the stipe with the scissor arms and the spring. The electromagnetic repulsion pushes the spring to spring up, tearing the stipe off along the cut, leaving a torn base in place.

[0021] The beneficial effects of the basic scheme are: by using a mushroom protective harvester to harvest bright red milk mushrooms, tearing can be used instead of cutting to improve the quality of harvesting and mycorrhizal seed preservation. At the same time, electromagnetic repulsion replaces manual plucking, enhancing the standardization of bright red milk mushroom harvesting, saving manpower and improving the efficiency of wild population conservation efforts for bright red milk mushrooms.

[0022] Furthermore, the front end of the scissor arm of the mushroom protective harvester is also fixedly connected to a semi-airbag. When the two semi-airbags approach each other with the scissor arm, they can be spliced ​​together to form an airbag disc. The opening of the airbag disc faces the scissor hinge and tilts upward.

[0023] The beneficial effects of the basic solution are: the semi-airbags fixedly connected to the front end of the scissor arms can be assembled into an airbag disc to provide some protection for the torn brightly colored milk mushrooms, preventing them from being blown away by shrapnel and causing damage, thus improving the quality of protective harvesting of brightly colored milk mushrooms. When not in use, the airbags can be depressurized for easy storage of the mushroom protective harvester.

[0024] Furthermore, the surface of the semi-airbag facing the ground is provided with a puncture-resistant layer.

[0025] The beneficial effects of the basic design are: the puncture-resistant layer at the bottom of the semi-airbag enhances the durability of the mushroom protective harvester in wild, brightly colored lactus mushroom harvesting sites, preventing the semi-airbag from being worn or punctured by debris such as branches and stones on the ground, thus reducing the risk and cost of using the mushroom protective harvester.

[0026] Furthermore, an anti-electric shock sleeve is fixedly connected to the inside of the handle. The anti-electric shock sleeve is fitted onto the electrical contacts and the electrical arc strip. The anti-electric shock sleeve fitted onto the electrical contacts is shorter than the anti-electric shock sleeve fitted onto the electrical arc strip, and the inner diameters of the two anti-electric shock sleeves are different.

[0027] The beneficial effects of the basic design are: by designing an anti-electric sleeve, the safety of the electrical contacts and arc strips on the inside of the handle is enhanced, thereby improving the safety of the mushroom protective harvester.

[0028] Furthermore, a spring with the same inner and outer diameter as the anti-electric sleeve on the electric contact arc bar is fixedly connected to the end of the anti-electric sleeve that is sleeved on the electric contact arc bar away from the handle.

[0029] The beneficial effects of the basic solution are: the spring on the anti-electric sleeve can guide the electric arc strip to contact the electric contact point for accurate power transmission, while avoiding the waste of battery power due to continuous power transmission to the electric arc strip and electric contact point, which would affect the battery life of the mushroom protective harvester.

[0030] Furthermore, the natural insect repellent sprinkled at the base of the pine tree is made from the following ingredients by weight: 4-5 parts lemon peel, 4-5 parts orange peel, 1.5-2 parts white vinegar, and 0.5-2 parts peppermint essential oil.

[0031] The beneficial effects of the basic solution are: using insect repellents made from natural raw materials to a certain extent eliminate fleas that are highly harmful to wild milk mushrooms, while avoiding damage to the environment of wild milk mushroom harvesting sites from pesticides, thus balancing the advantages and disadvantages between environmental protection and increased production of wild milk mushrooms.

[0032] Furthermore, the culture medium used is made from the following raw materials in parts by weight: 180-200 parts potato, 15-20 parts agar, 2-6 parts yeast extract, 3-6 parts soybean peptone, 15-20 parts glucose, 0.01-0.1 parts compound vitamins, and 900-1000 parts pine needle water.

[0033] The beneficial effect of the basic scheme is that by identifying the peptone in the basic *Lactarius deliciosus* spawn culture medium as plant-derived soybean peptone, it promotes the increase of wild *Lactarius deliciosus* regeneration yield.

[0034] Furthermore, the daily management of the conservation site according to the conservation methods of *Lactarius deliciosus* refers to adjusting the humidity and canopy density of the conservation site, and timely supplementing with insect repellents to prevent and control pests and diseases.

[0035] The beneficial effects of the basic plan are: through the scientific conservation and management of wild brightly colored mushroom picking sites, on the one hand, the yield of wild brightly colored mycorrhizae can be increased to a certain extent, creating more economic benefits; on the other hand, the wild environment and wild brightly colored latex mushroom species have not been completely changed, thus protecting the number of wild brightly colored latex mushroom populations and their renewable and sustainable development.

[0040] The following detailed description illustrates the specific implementation method:

[0041] Example 1

[0042] The basics are as follows: Figure 1 , Figure 2 and Figure 3 As shown: A method for protecting the wild population of *Lactarius deliciosus*, characterized in that:

[0043] Step 1, Site Selection: Selecting conservation sites with evenly distributed and consistent site conditions for *Lactarius deliciosus* will help with subsequent conservation and propagation management and improve the conservation efficiency of wild *Lactarius deliciosus* populations.

[0044] Step 2, Protective Harvesting: When the product is commercially mature, use a mushroom protective harvester to harvest the brightly colored latex mushrooms at the junction of the stipe and root of the fruiting body.

[0045] Harvesting bright red milk cap mushrooms using a mushroom protective harvester involves aligning the groove on the spring of the mushroom protective harvester with the stipe of the bright red milk cap mushroom fruiting body, placing the scissors horizontally close to the stipe, marking the required harvesting height with a leveling plate, and then simultaneously cutting vertically into the stipe with the scissor arms and the spring. The electromagnetic repulsion pushes the spring to spring up, tearing the stipe off along the cut, leaving a tear base about 1 cm high in place.

[0046] The tearing and picking effect of the mushroom protective harvester can effectively extend the shelf life of the harvested bright red milk mushrooms, reduce the probability of mycorrhizal infection by pathogens, and improve the protection efficiency of wild populations of bright red milk mushrooms.

[0047] Step 3, Seed preservation and conservation: When harvesting bright red milk mushrooms, do not harvest young or overripe mushrooms, and retain at least one bright red milk mushroom fruiting body in each mushroom bed. After harvesting bright red milk mushrooms, avoid trampling and removing the base of the stem to increase the yield of wild bright red milk mushrooms.

[0048] Step 4, pest control and propagation: Sprinkle natural insect repellent around the mushroom ponds at the conservation site, and prepare a culture medium suitable for the absorption and utilization of *Lactarius deliciosus* to supplement the nutrients at the conservation site. Perform daily management of the conservation site according to the conservation methods for *Lactarius deliciosus*. Through scientific conservation management of the *Lactarius deliciosus* conservation site, the number of wild *Lactarius deliciosus* populations can be protected while increasing the yield of wild *Lactarius deliciosus*.

[0049] The natural insect repellent sprayed at the base of the pine trees is made from the following ingredients by weight: 4-5 parts lemon peel, 4-5 parts orange peel, 1.5-2 parts white vinegar, and 0.5-2 parts peppermint oil. This natural insect repellent can, to some extent, repel fleas that are a major threat to wild milk mushrooms, while also preventing pesticide damage to the environment of wild milk mushroom harvesting sites.

[0050] The culture medium used for propagation is made from the following raw materials in parts by weight: 180-200 parts potato, 15-20 parts agar, 2-6 parts yeast extract, 3-6 parts soybean peptone, 15-20 parts glucose, 0.01-0.1 parts compound vitamins, and 900-1000 parts pine needle water. Soybean peptone is used to replace animal-derived peptone to promote the regeneration and increase of wild bright red lactus mushroom yield.

[0051] Daily management of the conservation site according to the conservation methods for bright red milkweed refers to adjusting the humidity and canopy density of the conservation site, and timely supplementing with insect repellent to prevent and control pests and diseases.

[0052] Example 2

[0053] The difference from the above embodiments is that, as shown in the appendix Figure 2 , Figure 3 As shown: The mushroom protective harvester includes scissors. Each scissor arm 3 has a spring piece 4 hinged to its upper front surface, parallel to the scissor arm 3. Each scissor arm 3 has a height plate 6 welded to its front end, extending vertically downwards. Each spring piece 4 has a groove 5 with an opening facing the cutting side in the middle of its upper surface. The spring pieces 4 extend along the scissor arm 3. The ends of the two spring pieces 4 near the scissor hinge 9 are hinged together above the scissor hinge 9 by a top hinge 8. The top hinge 8 contains a magnetic component 14, and the scissor hinge 9 contains an electromagnet 15. The magnetic field activated by the electromagnet 15 repels the magnetic component 14. An electrical contact 11 is welded to the inside of one handle 1, and an electrical contact arc strip 2 is welded to the inside of the other handle 1. The electrical contact 11 is located on the movement trajectory of the electrical contact arc strip 2. The handle 1 is away from the scissor hinge. Batteries 13 are glued to the ends of all parts 9. The batteries 13 are connected to the electrical contacts 11, the electric arc strip 2, and the electromagnet 15. Anti-electric sleeves 10 are glued to the inside of the handle 1. The anti-electric sleeves 10 are fitted onto the electrical contacts 11 and the electric arc strip 2. The anti-electric sleeves 10 can improve the safety of the circuit conductivity. The anti-electric sleeves 10 fitted onto the electrical contacts 11 are shorter than the anti-electric sleeves 10 fitted onto the electric arc strip 2, and the inner diameters of the two anti-electric sleeves 10 are different. At the end of the anti-electric sleeve 10 fitted onto the electric arc strip 2 away from the handle 1, a spring 12 with the same inner and outer diameters as the anti-electric sleeve 10 fitted onto the electric arc strip 2 is glued. The spring 12 can guide the electric arc strip 2 and guide the separation of the electric arc strip 2 and the electrical contacts 11, so as to avoid the waste of power caused by the continuous connection of the electromagnet 15 circuit.

[0054] The front end of the scissor arm 3 of the mushroom protective harvester is also attached with a semi-airbag 7. When the two semi-airbags 7 approach each other with the scissor arm 3, they can be spliced ​​into an airbag disc. The opening of the airbag disc faces the scissor hinge 9 and tilts upward. The surface of the semi-airbag 7 facing the ground is provided with a puncture-resistant layer, which is made of thermoplastic polyolefin (TPO) material.

[0055] The specific implementation process is as follows: Before using the mushroom protective harvester to harvest the bright red milk mushrooms, the staff first inflates the semi-airbag 7, then selects a bright red milk mushroom fruiting body of suitable size for harvesting, and marks the appropriate harvesting height by placing the elevation plate 6 against the ground. At this time, the puncture-resistant layer at the bottom of the semi-airbag 7 can prevent the semi-airbag 7 from being punctured by debris on the ground. The staff pushes the harvester horizontally to insert the umbrella handle into the groove 5 on the spring piece 4, and pushes the handle 1 horizontally to close it at the umbrella handle position to cut into the scissor arm 3 and the spring piece 4. When the cut into the umbrella handle reaches the appropriate angle, the electric arc strip 2 in the anti-electric sleeve 10 on the handle 1 protrudes the spring 12 and contacts the electric contact 11, connecting the circuit between the electromagnet 15 and the battery 13 in the scissor hinge 9. The magnetic field of the electromagnet 15 repels the magnetic component 14, causing the two spring pieces 4 to pop upward. As the scissor arm 3 cuts into the spring piece 4 of the umbrella handle, the umbrella handle is torn off along the cutting notch, and the bright red milk mushroom falls into the airbag tray formed by the splicing of the semi-airbag 7, preventing the bright red milk mushroom from being damaged.

[0056] Then, relying on the elasticity of the spring 12 on the anti-electric sleeve 10, the electrical contact 11 and the electrical arc strip 2 are separated, disconnecting the circuit between the electromagnet 15 and the battery 13 to avoid wasting electricity. The staff collects and preserves the torn bright red lactus mushrooms. Because the torn stem end can preserve a relatively intact cell wall, the shelf life of the bright red lactus mushrooms can be extended. At the same time, the mycorrhizae left in place can also preserve a relatively intact cell wall structure to avoid soil pathogen infection and improve the protection efficiency of the bright red lactus mushroom wild population. After harvesting, the gas in the semi-airbag 7 can be released, and the semi-airbag 7 can be folded for easy storage of the harvester.
