Description

Technical Field

[0001] The utility model belongs to the technical field of mushroom scale planting, and particularly relates to a preparation device for a fungus culture medium. Background Art

[0002] Shiitake mushrooms are also known as fragrant mushrooms, fragrant mats, flower mushrooms, winter mushrooms, etc. They are typical wood-rotting mushrooms from the genus Lentinus of the family Agaricus. Shiitake mushrooms are divided into four types according to their appearance and quality: flower mushrooms, thick mushrooms, thin mushrooms, and diced mushrooms; according to the growing season, they can be divided into three categories: autumn mushrooms, winter mushrooms, and spring mushrooms. Shiitake mushrooms are best when they have a strong flavor, thick meat, smooth and beautiful appearance, uniform size, tight and fine white gills, short and thick stems, and a white frost on the surface. Shiitake mushrooms contain sirtuin, choline, tyrosine, oxidase, and certain nucleic acid substances.

[0003] In the prior art, mushroom sticks can be used as culture medium to grow shiitake mushrooms. The structure of the mushroom sticks is: a strip-shaped plastic bag, the plastic bag is filled with culture medium, and 2-5 holes are punched on the side wall of the mushroom sticks.

[0004] For example, the patent application number CN201210592324.X discloses an indoor high-bay three-dimensional cultivation method of shiitake mushrooms, which is carried out in the following steps:

[0005] (1) Preparation of indoor high-rise mushroom sheds and shelves in mushroom sheds: The foundation of the mushroom shed is prepared with stones stacked, the underground rear wall is 1 meter high, and the above-ground rear wall is stacked 0.8 meters. The front and back walls are coated with cement, color steel plates, and benzene plates with a weight of 13 kilograms per cubic meter. The color steel plates are 150 mm thick, the benzene plates are 100 mm thick, and the length is 1.4 meters. The distance between the shelves is 1.2 meters. Iron wire rings should be left between the distances. The bottom of each shelf should be pressed down with 2 steel bars. The beam height is 0.24 meters. The shelves in the mushroom shed are 60 meters long, 90 centimeters wide, and 2 meters high. There are seven layers in total, and the distance between the layers is 25 centimeters. A total of 5,000 bags of mushrooms can be placed on each shelf.

[0006] (2) Preparation and cultivation of mushroom sticks: The raw materials should be fresh, free of impurities and mold, and placed in the culture medium. The mushroom sticks should be inoculated with 3 holes on one side and sealed with adhesive tape. The culture medium: 70%-75% sawdust, 10%-12% bran, 2%-4% corn flour, 2-3% corn flour, 0.4%-0.5% urea, 0.5% superphosphate, 1%-2% sugar, mixed by physical stirring.

[0007] (3) Spawning: The sprouting stage must be carried out in a dark room or dim light environment. The room temperature should be above 23-25℃. Use a 4 cm long nail to pierce 2 cm deep holes. The piercing should be done three times. The first time, 10-15 holes should be pierced when the mycelium just grows to the surface of the inoculated hole. The second time, 20-25 holes should be pierced when the mycelium fills the bag. The third time, 25-30 holes should be pierced one month after the second time.

[0008] (4) Cultivation of shiitake mushrooms in indoor high-bay mushroom sheds: According to the growing environment of shiitake mushrooms, 40 mushroom sticks can be placed per square meter, 710 mushroom sticks can be placed on each layer, and a set of shiitake mushroom racks can hold 5,000 mushroom sticks. The mushroom bags are arranged in racks, and the horizontal type uses 12 cm × 55 cm or 13.5 cm × 55 cm.

[0009] For example, the patent application number CN201610345098.3 discloses a method for growing mushroom spawn, which includes the following steps:

[0010] 1) Raw materials and formula: collect fruit tree trunks or branches, cut them, dry them, and crush them as the main ingredients; wheat bran, sucrose, and lime are auxiliary materials, and the proportions are: 72% fruit tree chips, 25% wheat bran, 2% sucrose, and 1% lime. The main and auxiliary materials are fully mixed.

[0011] 2) Making mushroom sticks: Use a 4L polypropylene plastic bag as the cultivation bag, put the evenly mixed culture medium into the bag and tie the mouth.

[0012] 3) Fermentation of mushroom sticks: Place the prepared mushroom sticks in the fermentation tank. When the tank is full, inject clean water into the tank and control the temperature at 10-15 degrees for 18-24 hours. When white bacteria are produced in the bag, take the mushroom sticks out of the tank.

[0013] 4) Put the mushroom sticks into the shed: Place the fermented mushroom sticks in the shed. The temperature in the shed is controlled at 15-28 degrees, the relative humidity is controlled at 65%-80%, and air circulation is maintained.

[0014] 5) Management of mushroom sticks: After about 30-40 days of inoculation, the mycelium will basically cover the entire bag. After about 60 days, mushrooms will emerge. At this time, tools are needed to puncture the plastic bag in the area where mushrooms emerge to facilitate smooth production of mushrooms.

[0015] For example, the patent application number CN201510198045.9 discloses a method for growing shiitake mushrooms, which includes the following steps:

[0016] Cultivation of fungus strains: Take the fruiting bodies of shiitake mushrooms, separate the tissues, and culture them in a culture medium for 8-12 days. White fluffy mycelium grows in the tissues as the mother strain. After the mother strain is sterilized, it is propagated and cultured to obtain the original strain, and the original strain is propagated and cultured to obtain the cultivated strain.

[0017] Inoculation: In a sterile environment, inoculate the culture onto the mushroom stick.

[0018] Spawning: Place the inoculated mushroom sticks indoors and control the indoor temperature between 18-25°C. The incubation period is 32-38 days and the relative humidity of the air is controlled at 60-70%.

[0019] Management during the mushroom period: After the spawning, the indoor temperature difference should be controlled between 8-12℃, the highest temperature should not exceed 28℃, the lowest temperature should not be lower than 6℃, the maturity period is 6-8 days, 600-1400 lux of natural light, and the relative humidity of the air should be controlled at 85-90%, then the mushrooms can be produced.

[0020] It can be seen from the above patents that the existing shiitake mushroom culture medium includes sawdust, sugar, wheat bran and gypsum, etc. The amount of sawdust is very large, reaching more than 70%, and the sawdust (usually dry, and water needs to be added to prepare the culture medium) is usually stored by stacking. The sawdust is transported to the corresponding stirring structure to mix with other raw materials, and then sent to the storage bin after mixing, and finally bagged by the corresponding packaging structure to obtain mushroom sticks.

[0021] For example, the patent with application number CN201821070420.7 discloses a culture medium mixing device for growing shiitake mushrooms, including a chassis, a feed bin is connected to the middle position of the top of the chassis, a rotating rod is inserted into the top of the right side of the chassis, the left end of the rotating rod passes through the right side of the chassis and is connected to the left side of the inner wall of the chassis through a bearing, a mixing blade is connected to the outer surface of the rotating rod, a driven wheel is connected to the right end of the rotating rod, a rotating motor is connected to the right side of the top of the chassis, and the output end of the rotating motor A driving wheel is connected, and the driving wheel and the driven wheel are connected by a belt drive, inclined plates are connected on both sides of the inner wall of the chassis and below the mixing blades, a through pipe is connected to the bottom of the inclined plate, an electric push rod is connected to the left side of the inner wall of the chassis, the free end of the electric push rod is connected to one end of the baffle, and the other end of the baffle passes through the left side of the through pipe and extends to the inside thereof, a card block is connected to the right side of the inner wall of the through pipe, and a card slot for cooperating with the baffle is provided on the left side of the card block, and a discharge port is provided at the bottom of the right side of the chassis.
