Description

Technical Field

[0001] The invention belongs to the field of agricultural product planting, and specifically relates to a cultivation method for selenium-enriched edible fungi. Background Art

[0002] Selenium is also an essential trace element for the human body. Selenium participates in the synthesis of a variety of selenium-containing enzymes and selenoproteins in the human body. Among them, glutathione peroxidase catalyzes the conversion of hydroperoxides or lipid peroxides into water or various alcohols in the body, eliminates the attack of free radicals on the biofilm, and protects the biofilm from oxidative damage; selenium participates in the formation of iodinated thyroxine deiodinase. Therefore, selenium is called the "king of cancer prevention" among trace elements in the human body by scientists. Selenium has a significant inhibitory and protective effect on various cancers such as colon cancer, skin cancer, liver cancer, and breast cancer. Its intermediate metabolite methyl enol in the body has a strong anti-cancer activity. Selenium has a synergistic antioxidant effect with nutrients such as vitamin E, allicin, linoleic acid, germanium, and zinc, increasing antioxidant activity. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals.

[0003] Shiitake mushrooms, also known as flower mushrooms, hericium erinaceus, fragrant mushrooms, fragrant mushrooms, fragrant mushrooms, winter mushrooms, and fragrant wild mushrooms, are the second largest edible mushrooms in the world and one of my country's specialties. They are known as "mountain treasures" among the people. They have a strong fragrance and rich nutrition. They contain 18 kinds of amino acids, 7 of which are essential to the human body; the ergosterol contained in shiitake mushrooms can be converted into vitamin D, which has the effect of enhancing the body's resistance to diseases and preventing colds; the polysaccharides in shiitake mushrooms have anti-tumor effects, and adenine and choline can prevent cirrhosis of the liver and vascular sclerosis; tyrosine oxidase has the effect of lowering blood pressure; double-stranded RNA can induce the production of interferon and has antiviral effects. Using edible fungi as carriers to convert inorganic selenium into organic selenium is one of the research hotspots in the field of fungal health foods. The current cultivation method of selenium-rich shiitake mushrooms has problems such as unscientific culture medium composition, high culture medium cost, complicated cultivation process and low selenium content in the cultivated products. Therefore, some people have begun to grow selenium-rich edible fungi in mountainous areas. The present invention provides a cultivation method for selenium-rich edible fungi, which increases the survival rate of selenium-rich edible fungi while increasing the selenium content of selenium-rich edible fungi, thereby improving the quality of selenium-rich edible fungi. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a cultivation method of selenium-rich edible fungi, so as to increase the survival rate of selenium-rich edible fungi and at the same time increase the selenium content per use, thereby improving the quality of selenium-rich edible fungi.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: comprising the following steps:

[0006] Step 1: Plant edible fungi using an anti-trampling device. When the trample block is stepped on, the trample block will generate a downward force, thereby driving the planting medium to move downward. When the planting medium moves downward, the edible fungi will move downward with it. At the same time, the protective layer will not move under the restriction of the vertical rod, and will be hidden under the protective layer. Under the action of the torsion spring, when the pressure on the trample block disappears, the planting medium will rebound to its original position driven by the torsion spring;

[0007] Step 2: Use common materials to prepare culture medium, including selenium-enriched rice bran, cottonseed hulls, bran, corn flour, soybean meal, mulberry, ginkgo, mushroom mulberry and fruit peel;

[0008] Step 3: mixing the water absorbing material into the culture medium to form a mixture;

[0009] Step 4: Crush the mixture to obtain selenium-rich nutrient solution, and spray it to the edible fungi planting area. First, place the stirring rod close to the side wall of the stirring barrel and rotate the stirring rod to make the stirring rod move in a circular motion. Then gradually reduce the diameter of the circle to make the stirring rod move in a circular motion until the stirring rod is close to the center of the circle. In this way, the water-absorbing material in the mixture is crushed, and the water in the water-absorbing material is discharged to obtain the nutrient solution, and then the nutrient solution is sprayed to the edible fungi planting area.

[0010] The following beneficial effects are achieved after adopting the above scheme: the anti-trampling device for planting selenium-rich edible fungi can prevent the selenium-rich edible fungi from being trampled by patrol personnel passing through the planting area when the selenium-rich edible fungi are growing, thereby avoiding damage to the selenium-rich edible fungi and increasing the survival rate of the selenium-rich edible fungi. The use of common materials to make culture media can facilitate the acquisition of materials, and the use of absorbent materials to absorb the nutrient solution in the culture media material, and then the absorbent materials are crushed to obtain the nutrient solution, and then the nutrient solution is sprayed onto the edible fungi planting area.

[0011] Furthermore, the specific steps of planting edible fungi using the anti-trampling device are as follows: select a forest land for cultivation, use the open space in the forest to make a bed, set a planting culture medium on the bed, fix a torsion spring on the top of the planting culture medium, fix a trampling block on the top of the torsion spring, the trampling block extends through the protective layer to the outside of the protective layer, the protective layer is a grid steel plate, both sides of the steel plate are flush with the surrounding soil, both sides of the steel plate are detachably connected to vertical rods, the vertical rods extend into the soil, the bottom of the vertical rods are sharp, sliders are set on both sides of the planting culture medium, slide rails are set on the vertical rods, the planting culture medium and the vertical rods are slidably matched through the sliders and the slide rails, the fungus species are placed in the planting culture medium for covering with soil cultivation, and a protective layer is set above the planting culture medium.

[0012] Further, the culture medium includes the following components in parts by weight: 30-50 parts of selenium-enriched rice bran, 5-10 parts of cottonseed hulls, 3-6 parts of bran, 2-5 parts of corn flour, 3-5 parts of soybean meal, 3-5 parts of mulberries, 2-5 parts of ginkgo, 3-5 parts of mushroom mulberries, and 5-10 parts of fruit peels.

[0013] Furthermore, after the water absorbing material is mixed with the substance in the culture medium to form a mixture, the substance in the mixture is left to stand for dehydration, so that the water absorbing material absorbs the water in the substance.

[0014] Further, the vertical pole extends to 0.7-1 meter from the soil.

[0015] Furthermore, the bed width is 1-1.4 meters.

[0016] Further, the mixture is allowed to stand for 5-8 hours.

[0017] Beneficial effect: when the inspectors are conducting inspections, after stepping on the pedal block, the pedal block will generate a downward force, thereby driving the planting medium to move downward, and when the planting medium moves downward, the edible fungi will move downward with it, and at the same time, the protective layer will not move under the restriction of the vertical rod, and will be hidden under the protective layer, so that when the inspectors are conducting inspections and step on the pedal block: the fungi will not be accidentally stepped on by the inspectors, and the situation of accidentally stepping on the fungi is avoided to a certain extent: and there are several connecting parts, so that when the inspectors step on the pedal block, the planting medium will slowly move downward in turn, and to a certain extent reduce the impact of the planting medium on the fungi when it moves vertically, and at the same time, under the action of the torsion spring, when the pressure on the pedal block disappears, the planting medium will rebound to its original position driven by the torsion spring, and will not affect the growth of selenium-rich edible fungi mycelium, thereby increasing the survival rate of selenium-rich edible fungi.

[0018] Adding selenium-rich rice bran, cottonseed hulls, bran, corn flour, soybean meal, mulberries, ginkgo, mushrooms and fruit peels into the culture medium, the selenium-rich content of these substances can not only provide abundant selenium elements for selenium-rich edible fungi, but also improve the quality of selenium-rich edible fungi.

[0019] The substances in the culture medium are mixed with the water-absorbing material and allowed to stand, and the moisture of the substances in the water-absorbing culture medium is absorbed into the water-absorbing material, and the substances in the culture medium remain in a dry state for easy storage.

[0020] The substances in the dry culture medium are stirred and mixed with the water-absorbing material, and a stirring rod is used to make circular motion close to the side wall of the stirring barrel. The water-absorbing material is broken by the pressing pressure applied to the stirring rod, and the water in the water-absorbing material overflows. Then the diameter of the circle is gradually reduced, and the stirring rod is made to make a circular motion until the stirring rod is close to the center of the circle, so that the substances in the culture medium are mixed with the water. By providing the water-absorbing material, compared with the prior art, the step of adding water to the stirring barrel can be omitted, thereby avoiding the situation that adding water to the beaker may lead to impure raw material concentration and thus cause mutation of selenium-rich edible fungi during cultivation. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The present invention is a flow chart of a method for cultivating selenium-rich edible fungi according to an embodiment of the present invention.

[0022] Figure 2 2 is a structural diagram of an anti-trampling device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0023] The following is further described in detail through specific implementation methods:

[0024] The reference numerals in the drawings of the specification include: protective layer 1, vertical rod 2, planting medium 3, bed 4, slider 5, pedal block 6, torsion spring 7.

[0025] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown:

[0026] A method for cultivating selenium-rich edible fungi comprises the following steps:

[0027] Step 1: Planting edible fungi using an anti-trampling device. The specific steps of planting edible fungi using an anti-trampling device are as follows: select a forest land for cultivation, use the open space in the forest to make a bed 4 with a width of 1-1.4 meters, set a culture medium on the bed 4, and fix a torsion spring 7 on the top of the planting culture medium 3. The top of the torsion spring 7 is fixedly connected to a trampling block 6. The trampling block 6 extends through the protective layer 1 to the outside of the protective layer 1. The protective layer 1 is a grid steel plate. Both sides of the steel plate are flush with the surrounding soil. Both sides of the steel plate are detachably connected to vertical rods 2, which extend to 0.7-1 meters from the soil. The bottom of the vertical rod 2 is sharp, sliders 5 are set on both sides of the culture medium, and slide rails are set on the vertical rod 2. The culture medium and the vertical rod 2 are slidably matched through the sliders 5 and the slide rails, and the fungus species are placed in the planting culture medium 3 for soil covering cultivation, and a protective layer 1 is set above the culture medium.

[0028] Step 2: Use common materials to make a culture medium. When making the culture medium, mix the substances, which include the following components in parts by weight: 30-50 parts of selenium-rich rice bran, 5-10 parts of cottonseed hulls, 3-6 parts of bran, 2-5 parts of corn flour, 3-5 parts of soybean meal, 3-5 parts of mulberries, 2-5 parts of ginkgo, 3-5 parts of mushrooms, and 5-10 parts of fruit peels.

[0029] Step 3: Mix the water-absorbing material into the culture medium to form a mixture. After the water-absorbing material and the substances in the culture medium are mixed to form a mixture, the substances in the mixture are allowed to stand and dehydrate for 5-8 hours to allow the water-absorbing material to absorb the water in the substances.

[0030] Step 4: Crush the mixture to obtain selenium-rich nutrient solution. The specific steps of crushing the mixture are: use a stirring rod to stir, and the stirring method is: first place the stirring rod close to the side wall of the mixing barrel and rotate the stirring rod to make the stirring rod move in a circular motion, and then gradually reduce the diameter of the circle to make the stirring rod move in a circular motion until the stirring rod is close to the center of the circle, thereby crushing the water-absorbing material in the mixture, discharging the water in the water-absorbing material, obtaining the nutrient solution, and then spraying the nutrient solution onto the edible fungus planting area.

[0031] In this embodiment, during operation, selenium-rich edible fungi are planted on the planting culture medium 3. When the inspectors conduct inspection, after stepping on the pedal block 6, the pedal block 6 will generate a downward force, thereby driving the planting culture medium 3 to move downward. When the planting culture medium 3 moves downward, the edible fungi will move downward with it. At the same time, the protective layer 1 will not move under the restriction of the vertical rod 2, and will be hidden under the protective layer 1. Therefore, when the inspectors conduct inspection and step on the pedal block 6, the fungi will not be accidentally stepped on by the inspectors, which to a certain extent avoids the situation of accidentally stepping on the fungi. In addition, several connecting parts are provided, so that when the inspectors step on the pedal block 6, the culture medium will slowly move downward in turn, which to a certain extent reduces the impact of the culture medium on the fungi when it moves vertically. At the same time, under the action of the torsion spring 7, when the pressure on the pedal block 6 disappears, the culture medium will rebound to its original position driven by the torsion spring 7, which will not affect the growth of selenium-rich edible fungi mycelium, thereby increasing the survival rate of selenium-rich edible fungi.

[0032] Adding selenium-rich rice bran, cottonseed hulls, bran, corn flour, soybean meal, mulberries, ginkgo, mushroom mulberries and fruit peels into the culture medium, the selenium-rich content of these substances can not only provide abundant selenium elements for selenium-rich edible fungi, but also improve the quality of selenium-rich edible fungi.

[0033] The substances in the culture medium are mixed with the water-absorbing material and allowed to stand, and the moisture of the substances in the water-absorbing culture medium is absorbed into the water-absorbing material, and the substances in the culture medium remain in a dry state for easy storage.

[0034] The substances in the dry culture medium are stirred and mixed with the water-absorbing material, and a stirring rod is used to make circular motion close to the side wall of the stirring barrel. The water-absorbing material is broken by the pressing pressure applied to the stirring rod, and the water in the water-absorbing material overflows. Then the diameter of the circle is gradually reduced, and the stirring rod is made to make a circular motion until the stirring rod is close to the center of the circle, so that the substances in the culture medium are mixed with the water. By providing the water-absorbing material, compared with the prior art, the step of adding water to the stirring barrel can be omitted, thereby avoiding the situation that adding water to the beaker may lead to impure raw material concentration and thus cause mutation of selenium-rich edible fungi during cultivation.

[0035] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
