Cultivation techniques of straw mushroom in low temperature season
Seasonal arrangements are made for the cultivation of straw mushrooms from November to April.
Mushroom room set to use insulation, good moisturizing room cultivation. Each room is 15 square meters with three shelves. Each shelf is divided into 3 layers. The length of the rack is 3 meters and the width is 0.7 meters. The distance between the layers is 60 centimeters. The ground floor is 70 centimeters away from the ground. The edge of the rack is not against the wall, leaving two sidewalks in the middle. The room is covered with two layers of plastic film around the room and on the top. The room has doors and windows, and the light is bright. The room has good sealing performance and can achieve insulation, moisture retention, light transmission and ventilation.
Formulas for preparing culture materials are straw 300 kg, cow dung powder 15 kg, bran 20 kg, lime 20 kg, gypsum powder 1.5 kg. Dry rice straw is first immersed in 3% lime water for 8 hours, drained for use, and then mix the cow dung, bran, and gypsum powder, and mix well with water until the moisture content is 65%.
Shop material sowing 1 mushroom room disinfection. After the room was cleaned, lime was disinfected on the ground and then sealed and fumigated with formalin plus potassium permanganate for 24 hours. 2 mushroom room preheating. Coal stoves or smoke pipes can be used to preheat the cultivated mushroom house so that the room temperature can reach about 30°C. 3 planting material sowing. Drain the drained straws and weigh 250 grams each. Place them on a shelf in a regular repetitive pattern, with the elbows facing outwards. After finishing one layer, spread a 10 cm wide cow dung mixture from the outer edge at 5 cm, and spot the bacteria in the cow dung mixture. Then lay a second layer of straw, shrink it slightly inwards, spread it according to the first layer, and sow. After paving, the entire bed was trapezoidal, with a turtle back in the middle, and the seedlings were spread and spread. After sowing the strains, sprinkle the cow dung mixture to cover the strains, flatten them slightly, and use a bamboo arch to cover the film 30 cm high.
The first 3 days after inoculation, the germination management 1 is the time for the hyphae to colonize and germinate, and no light is needed. The room temperature should be controlled at 25°C-30°C, and the material temperature should be controlled at 28°C-32°C. Due to cultivation in the cold season, room temperature does not meet the requirement for straw mushroom growth. In order to make the room temperature reach about 30°C, it can be heated by a 1500 watt electric furnace, and can also be heated by a coal stove, and the indoor humidity should be maintained at 80%-85%. 2 After 4-5 days of sowing, mycelium has been sealed for half a time. At noon, the amount of ventilation is lifted to increase the amount of ventilation. At the same time, the water consumption is determined according to the hyphae consumption and the moisture content of the bed material layer. After 37-10 days, mycelium grows around the straw, which is the time of formation of the original kinks. Spray fine mist to the wall and aisle of the mushroom house once a day to increase the scattering light stimulation and induce mushroom bud formation. The room temperature should be kept at 28°C. °C -30 °C, humidity 90% - 95%, the material surface is dry and it is necessary to make up the water, the nozzle should not be directly upward mushroom bed, so as not to damage the mushroom buds.
Mushroom management After straw budding, the room temperature is controlled at 25°C-32°C and the humidity is maintained at 90%-95% by water spray. After 2-3 days, the fruit body primordium is enlarged from the small white dots, and the stipe, Caps did not extend out of the cover for harvesting. Do not pull hard when picking mushrooms, so as not to affect the mycelium of the material bed, affect the young mushroom development and the trend of mushroom, the first tidal mushroom is usually taken in 2-3 days, ventilation, cleaning the bed surface, and combined with water spray One-time 1% lime water and Pesticides were re-covered and bred after proper ventilation. The second mushroom management is basically the same as the head mushroom. From sowing to the first oyster mushroom is about 15 days, the whole fruiting period can receive two or three oyster mushrooms.
Mechanism of action of ibrutinib: ibrutinib is a small molecule BTK inhibitor that can covalently bind to cysteine residues in the active center of BTK, thereby inhibiting its activity. The full name of BTK is Bruton'styrosinekinase, which transmits signals in the BCR signaling pathway and cytokine receptor signaling pathway, and mediates the migration, chemotaxis and adhesion of B cells. Preclinical studies have shown that ibrutinib can inhibit the proliferation and survival of malignant B cells.
