Description

Technical Field

[0001] The invention relates to the field of planting Coprinus comatus, in particular to a planting method and equipment of Coprinus comatus with secondary soil covering. Background Art

[0002] Secondary soil covering of Coprinus comatus refers to two soil covering operations during the cultivation of Coprinus comatus. The first soil covering is mainly to cover a layer of soil after the mycelium (used to provide substances and energy for the growth and reproduction of fungi) grows to a certain stage. The purpose is to induce the mycelium to transform from vegetative growth to reproductive growth and promote the formation of primordium (fungus fruiting body, such as the cap and stipe of mushrooms). The secondary soil covering is a further operation after the first soil covering, usually after the primordium differentiates, the soil is covered again, which can better maintain the humidity of the culture medium, provide a more stable environment for the growth of Coprinus comatus fruiting body, and is conducive to the growth and development of the mushroom body, such as making the mushroom body more regular in shape, and can also increase the yield to a certain extent; For example, the prior art application number CN201520350834.5 discloses a factory-based cultivation of Coprinus comatus soil covering machine, comprising a frame, a pressing plate and a mud block forming device are arranged on the frame, the pressing plate is located above the mud block forming device, a driving device is arranged between the pressing plate and the frame, the driving device drives the pressing plate to rise and fall relative to the mud block forming device, the mud block forming device is provided with a storage cavity with an opening facing upward, and a sieve hole is arranged at the bottom of the mud block forming device; The above-mentioned prior art is known through actual use. After the main soil is piled in the storage cavity, the pressing plate moves downward under the drive of the driving device and drives the soil to be pressed down. After the soil is pressed, it is evenly squeezed out through the sieve holes, and the mud blocks formed by the sieve holes are directly poured and covered on the Coprinus comatus; however, this method of directly pouring and covering the soil can easily cause serious physical damage to the Coprinus comatus, causing the mushroom body or mushroom bud of the Coprinus comatus to break and damage, affecting the survival rate of the Coprinus comatus; at the same time, the soil is pressed by the driving device, which can easily lead to the difficulty in grasping the soil solidification thickness, which will cause the soil permeability to decrease and poor growth. For this reason, we have improved the above-mentioned prior art according to actual usage. Summary of the invention

[0013] A method for planting Coprinus comatus by secondary soil covering, which is applied to a Coprinus comatus secondary soil covering device, comprises the following steps: S1. Prepare the strains. Purchase high-quality Coprinus comatus strains. Choose strains with white, dense, and strong mycelium and a suitable age, generally 25 to 35 days; S2. Preparation of cultivation raw materials. Main materials: cottonseed hulls, corn cobs, sawdust, etc. are commonly used. Take cottonseed hulls as an example. It is rich in nutrients such as cellulose and can provide a carbon source for the growth of Coprinus comatus. Make sure it is dry and free of mold before use. Auxiliary materials: Add wheat bran, rice bran, gypsum, lime and other auxiliary materials. Wheat bran and rice bran are rich in nitrogen sources. Gypsum plays a role in regulating pH and increasing calcium. Lime is used to adjust the pH value to make the culture medium alkaline, which is conducive to the growth of Coprinus comatus. The pH value is generally controlled at around 7-8. S3. Prepare the culture medium. Mix the raw materials in a certain proportion, such as 78% cottonseed hulls, 20% wheat bran, 2% gypsum, and 2% lime. After mixing the raw materials thoroughly, add an appropriate amount of water to make the moisture content of the culture medium reach 56% - 65%. It is appropriate to hold the culture medium tightly with your hand and water seeps out between your fingers but does not drip; S4. Bagging and sterilization. Bagging: Put the prepared culture medium into plastic bags. The bags are generally made of polypropylene bags with specifications of 17-25 cm × 33-40 cm × 0.04-0.05 cm. When filling, it should be properly compacted to make the culture medium loose and tight, and the bag can be filled to about two-thirds. Sterilization can be carried out by normal pressure sterilization. Normal pressure sterilization is maintained at about 100℃ for 8-10 hours to kill the bacteria and pests in the culture medium; S5. Inoculation: After the sterilized culture medium temperature drops below 31°C, inoculate in a sterile environment (such as an inoculation box or sterile room). Sprinkle the bacteria evenly on the surface of the culture medium, or use the hole sowing method to make several holes in the culture medium, put the bacteria into the holes, and then cover it with a small amount of culture medium; S6. Mycelium culture: Place the inoculated bags in the culture room, keep the temperature at 20℃ - 25℃, and the relative humidity at 55% - 70%. Pay attention to ventilation and avoid strong light. Under suitable conditions, it takes about 20-30 days for the mycelium to grow all over the bags. S7, soil covering, soil covering material preparation: select fertile, loose, pest-free soil, such as farmland soil or forest soil, add appropriate amount of leaf mold and coarse sand to make the soil aeration and water retention good, pour it into the frame and finally fall into the surface of Coprinus comatus to cover; First covering: After the mycelium has grown all over the bag, a layer of soil 3 to 6 cm thick is then covered to induce the mycelium to transform from vegetative growth to reproductive growth; Secondary soil covering: After the primordium differentiates, secondary soil covering can be carried out, and another layer of soil 1 - 1.6 cm thick can provide a better environment for the growth of fruiting bodies; S8. Harvest when the fruiting bodies of Coprinus comatus grow to 70% to 80% maturity, the cap has not yet opened, and the ring has just begun to loosen. When harvesting, hold the base of the stem with your hand and gently rotate it to pull it out to avoid damaging the surrounding small mushrooms.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the process of the opening area of ​​the cloth gradually moving into the frame, the soil will fall from the opening area to cover the upper surface of the Coprinus comatus. The opening area of ​​the cloth moves slowly to make the soil fall slowly, so that the soil can fall evenly on the Coprinus comatus, which is conducive to the growth of Coprinus comatus under relatively uniform and consistent soil conditions; at the same time, compared with directly dumping the soil, the soil gradually falls through the opening area of ​​the cloth, which can make the soil fall gently on the Coprinus comatus, causing less physical damage to the Coprinus comatus, minimizing the damage to the mushroom body, ensuring the quality of the Coprinus comatus, and avoiding the situation of breaking the mushroom body or damaging the mushroom bud by direct dumping; At the same time, the soil is gently dropped on the Coprinus comatus through the cloth to be more evenly distributed, which helps to keep the soil loose and breathable, and provide a good air environment for the growth of mycelium of Coprinus comatus; when injecting the soil, the scale set inside the No. 1 baffle and the No. 2 baffle in the sterilization device can be referred to to determine the thickness of the soil and ensure the temperature, humidity and air permeability; After the soil is injected into the frame, the cloth and the sponge ball in the grid device are respectively located below and in the middle of the soil, which can sterilize the middle and lower surface of the soil, making the sterilization more comprehensive; because many harmful microorganisms may lurk deep in the soil, the cloth and the sponge ball can act simultaneously to disinfect the bottom and middle of the soil more deeply, reducing the possibility of pathogens infecting Coprinus comatus from the middle and bottom of the soil; As the soil moves and is squeezed, the bactericidal liquid in the cloth and sponge ball will gradually be released into the soil, continuously providing the soil with supplementary bactericidal liquid, extending the residence time of the bactericidal liquid in the soil and improving the bactericidal effect.

[0031] This embodiment provides a method for planting Coprinus comatus with secondary soil covering, which is applied as in claim embodiment 1 and comprises the following steps: S1. Prepare the strains. Purchase high-quality Coprinus comatus strains. Choose strains with white, dense, and strong mycelium and a suitable age, generally 25 to 35 days; S2. Preparation of cultivation raw materials. Main materials: cottonseed hulls, corn cobs, sawdust, etc. are commonly used. Take cottonseed hulls as an example. It is rich in nutrients such as cellulose and can provide a carbon source for the growth of Coprinus comatus. Make sure it is dry and free of mold before use. Auxiliary materials: Add wheat bran, rice bran, gypsum, lime and other auxiliary materials. Wheat bran and rice bran are rich in nitrogen sources. Gypsum plays a role in regulating pH and increasing calcium. Lime is used to adjust the pH value to make the culture medium alkaline, which is conducive to the growth of Coprinus comatus. The pH value is generally controlled at around 7-8. S3. Prepare the culture medium. Mix the raw materials in a certain proportion, such as 78% cottonseed hulls, 20% wheat bran, 2% gypsum, and 2% lime. After mixing the raw materials thoroughly, add an appropriate amount of water to make the moisture content of the culture medium reach 56% - 65%. It is appropriate to hold the culture medium tightly with your hand and water seeps out between your fingers but does not drip; S4. Bagging and sterilization. Bagging: Put the prepared culture medium into plastic bags. The bags are generally made of polypropylene bags with specifications of 17-25 cm × 33-40 cm × 0.04-0.05 cm. When filling, it should be properly compacted to make the culture medium loose and tight, and the bag can be filled to about two-thirds. Sterilization can be carried out by normal pressure sterilization. Normal pressure sterilization is maintained at about 100℃ for 8-10 hours to kill the bacteria and pests in the culture medium; S5. Inoculation: After the sterilized culture medium temperature drops below 31°C, inoculate in a sterile environment (such as an inoculation box or sterile room). Sprinkle the bacteria evenly on the surface of the culture medium, or use the hole sowing method to make several holes in the culture medium, put the bacteria into the holes, and then cover it with a small amount of culture medium; S6. Mycelium culture: Place the inoculated bags in the culture room, keep the temperature at 20℃ - 25℃, and the relative humidity at 55% - 70%. Pay attention to ventilation and avoid strong light. Under suitable conditions, it takes about 20-30 days for the mycelium to grow all over the bags. S7, soil covering, soil covering material preparation: select fertile, loose, pest-free soil, such as farmland soil or forest soil, add appropriate amount of leaf mold and coarse sand to make the soil aeration and water retention good, pour it into the frame 1 and finally fall into the surface of the Coprinus comatus to cover; First covering: After the mycelium has grown all over the bag, a layer of soil 3 to 6 cm thick is then covered to induce the mycelium to transform from vegetative growth to reproductive growth; Secondary soil covering: After the primordium differentiates, secondary soil covering can be carried out, and another layer of soil 1 - 1.6 cm thick can provide a better environment for the growth of fruiting bodies; S8. Harvest when the fruiting bodies of Coprinus comatus grow to 70% to 80% maturity, the cap has not yet opened, and the ring has just begun to loosen. When harvesting, hold the base of the stem with your hand and gently rotate it to pull it out to avoid damaging the surrounding small mushrooms.

[0032] Working principle: first, start the servo motor 52 to drive the No. 1 gear 53 and the No. 2 gear 54 to rotate so that the No. 1 roller 24 in the support device 2 rotates. After the No. 1 roller 24 rotates, the cloth 21 will be rolled up, and then the solid area 22 will be placed in the frame 1 to block the lower opening of the frame 1. At this time, soil can be poured into the frame 1 and the soil can be flattened on the top of the solid area 22. Then, the frame 1 can be pushed to be above the Coprinus comatus that needs to be covered with soil. Then, start the servo motor 52 again to drive the cloth 21 to roll up so that the opening area 23 is gradually placed in the frame 1. In the process of the opening area 23 gradually moving into the frame 1, the soil in the frame 1 will slowly fall from the left end of the frame 1 to cover the upper surface of the Coprinus comatus to cover the Coprinus comatus. Repeat the above steps for multiple times to achieve multiple coverings. In the process of the opening area 23 gradually moving into the frame 1, the soil will slowly fall from the opening area 23 to cover the upper surface of the Coprinus comatus. The opening area 23 of the pull cloth 21 moves slowly to make the soil fall slowly, so that the soil can fall evenly on the Coprinus comatus, which is conducive to the growth of Coprinus comatus under relatively uniform soil conditions. In addition, compared with direct dumping of soil, the soil gradually falls through the opening area 23 of the pull cloth 21, so that the soil can fall gently on the Coprinus comatus, causing less physical damage to the Coprinus comatus, minimizing damage to the mushroom body, ensuring the quality of the Coprinus comatus, and avoiding direct dumping to break the mushroom body or damage the mushroom buds; At the same time, evenly covering the soil helps to keep the soil loose and breathable, providing a good air environment for the growth of Coprinus comatus mycelium.

[0033] Before use, the first baffle 41 and the second baffle 42 in the sterilization device 4 can be pushed or pulled by starting the electric telescopic rod 44 to flexibly move so that the distance between the first baffle 41 and the second baffle 42 can be flexibly changed, and the width of the soil stored in the frame 1 can be limited, and the coprinus comatus planted with different widths can be covered with soil, thereby increasing the adaptability of the coprinus comatus planting environment; At the same time, when injecting the soil, the scale 48 provided inside the first baffle plate 41 and the second baffle plate 42 can be referred to to determine the thickness of the soil, so as to avoid the situation that the soil is too thin, it is difficult to retain the moisture inside the soil, and the Coprinus comatus is prone to poor growth due to lack of water; and the soil is too thick, the air permeability inside the soil is poor, which will lead to uneven sizes of mushroom bodies; the appropriate thickness can also balance the temperature, humidity and air permeability of the soil; During the movement of the No. 1 baffle 41 and the No. 2 baffle 42, the water pump 46 can be started to transport the sterilizing liquid in the box 45 to the liquid collecting box 49 and the nozzle 43 through the hose 47, and the movement of the No. 1 baffle 41 and the No. 2 baffle 42 drives the nozzle 43 to move and evenly spray the sterilizing liquid on the cloth 21 and the sponge ball 33 in the grid device 3. After the soil is injected into the frame 1, the cloth 21 and the sponge ball 33 are respectively located below the soil and in the middle of the soil, and the middle and lower surface of the soil can be sterilized, and the sterilization is more comprehensive; because many harmful microorganisms may be hidden deep in the soil, through the simultaneous action of the cloth 21 and the sponge ball 33, the bottom and middle of the soil can be disinfected more deeply, reducing the possibility of pathogens infecting Coprinus comatus from the middle and bottom of the soil; As the soil moves and is squeezed, the bactericidal liquid in the sponge ball 33 is gradually released into the soil, continuously providing the soil with a supplement of bactericidal liquid, prolonging the residence time of the bactericidal liquid in the soil, and improving the bactericidal effect; During the falling process of soil, the woven net composed of the horizontal rod 31 and the vertical rod 32 can play a buffering role. If the soil falls directly onto the pull cloth 21 from a higher position, the greater impact force may cause the soil to compact or splash, while the woven net can slow down the falling speed of the soil, allowing the soil to fall onto the pull cloth 21 in a softer way, thereby keeping the soil in a good loose state and protecting the pull cloth 21 to extend its service life. The woven net can also block the soil when the pull cloth 21 moves, preventing the pull cloth 21 from moving and causing the soil to move over a large range, resulting in uneven soil. For relatively dry soil, dust is easily generated during the falling process. The woven net can prevent the soil from falling directly and quickly, reducing the occurrence of dust. This can not only prevent dust from flying and polluting the environment, but also is beneficial to the health of operators. At the same time, it can avoid soil loss caused by dust and filter large particles in the soil to prevent large particles from causing damage to Coprinus comatus.

It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.

10. A method for planting Coprinus comatus by secondary soil covering, which is applied to a Coprinus comatus secondary soil covering device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Prepare the strains. Purchase high-quality Coprinus comatus strains. Choose strains with white, dense, and strong mycelium and a suitable age, generally 25 to 35 days; S2. Preparation of cultivation raw materials. Main materials: cottonseed hulls, corn cobs, sawdust, etc. are commonly used. Take cottonseed hulls as an example. It is rich in nutrients such as cellulose and can provide a carbon source for the growth of Coprinus comatus. Make sure it is dry and free of mold before use. Auxiliary materials: Add wheat bran, rice bran, gypsum, lime and other auxiliary materials. Wheat bran and rice bran are rich in nitrogen sources. Gypsum plays a role in regulating pH and increasing calcium. Lime is used to adjust the pH value to make the culture medium alkaline, which is conducive to the growth of Coprinus comatus. The pH value is generally controlled at around 7-8. S3. Prepare the culture medium. Mix the raw materials in a certain proportion, such as 78% cottonseed hulls, 20% wheat bran, 2% gypsum, and 2% lime. After mixing the raw materials thoroughly, add an appropriate amount of water to make the moisture content of the culture medium reach 56% - 65%. It is appropriate to hold the culture medium tightly with your hand and water seeps out between your fingers but does not drip; S4. Bag filling and sterilization. Bag filling: Put the prepared culture medium into plastic bags. The bags are generally made of polypropylene bags with specifications of 17-25 cm × 33-40 cm × 0.04-0.05 cm. When filling, it should be properly compacted to make the culture medium loose and tight, and the bag should be filled to about two-thirds. Sterilization can be carried out by normal pressure sterilization. Normal pressure sterilization is maintained at about 100℃ for 8-10 hours to kill the bacteria and pests in the culture medium; S5. Inoculation: After the sterilized culture medium temperature drops below 31°C, inoculate in a sterile environment (such as an inoculation box or sterile room). Sprinkle the bacteria evenly on the surface of the culture medium, or use the hole sowing method to make several holes in the culture medium, put the bacteria into the holes, and then cover it with a small amount of culture medium; S6. Mycelium culture: Place the inoculated bags in the culture room, keep the temperature at 20℃ - 25℃, the relative humidity at 55% - 70%, and pay attention to ventilation and avoid strong light. Under suitable conditions, it takes about 20-30 days for the mycelium to fill the bags; S7, covering with soil, preparation of covering materials: select fertile, loose, disease- and insect-free soil, such as farmland soil or forest soil, add appropriate amount of leaf mold and coarse sand to make the soil have good air permeability and water retention, pour it into the frame (1) and finally fall into the surface of the Coprinus comatus to cover it; First covering: After the mycelium has grown all over the bag, a layer of soil 3 to 6 cm thick is then covered to induce the mycelium to transform from vegetative growth to reproductive growth; Secondary soil covering: After the primordium differentiates, secondary soil covering can be carried out, and another layer of soil 1 - 1.6 cm thick can provide a better environment for the growth of fruiting bodies; S8. Harvest when the fruiting bodies of Coprinus comatus grow to 70% to 80% maturity, the cap has not yet opened, and the ring has just begun to loosen. When harvesting, hold the base of the stem with your hand and gently rotate it to pull it out to avoid damaging the surrounding small mushrooms.
