Straw mushroom is a typical high-temperature edible mushroom. When it is below 28 degrees Celsius, it does not produce mushrooms. If it is less than 25 degrees Celsius, the germination cannot proceed smoothly. The mycelium below 10 degrees Celsius is dead. It has always been one of the main varieties in the south of China. After the mushroom moved northward, the straw mushroom had been cultivated using fermented rot clinker, and the yield was low and unsteady. After years of experiments, the author has developed a high-yielding cultivation technique for straw-wrapped straw and straw raw materials. Under the condition of good breeding methods, the efficiency of straw mushroom cultivation biology is stable at more than 40%, and the higher ones can exceed 50%. as follows:
First, the use of the detoxification strains of the virus-free species of straw mushroom has the bacteria itself does not carry any virus pathogens, strong resistance, high yield and other obvious advantages. And it should also be based on the whereabouts of the product selection, such as large grain type V23, suitable for fresh sales or drying; medium and large grain type of agricultural V42, both suitable for fresh sales, can also be salted processing; other small and medium grain suitable for cans Processing and so on. The bacteria production process is the same as conventional.
Second, drug treatment mushroom shed can generally use all diseases to trace the solution to the mushroom shed for carpet spray, the old mushroom shed should be sprayed 2 times, spraying after the drying shed to completely kill the virus and other pathogens to ensure production The cleanliness of the place creates conditions for smooth production.
Third, the advantages and disadvantages of earth-covered material treatment of earth-covered material have a direct impact on the cultivation effect of straw mushroom. Treatment method: vegetable greenhouses are cultivated with layered soil or vegetable garden soil, calculated according to the use of 5 to 6 cubic meters per 200 square meters, taken out for drying, crushing and standby; 600 kg of cow dung, 600 kg of chicken dung, crushed urea, 20 kg, and over Calcium phosphate 100 kg, gypsum powder 40 kg, biological starter 12 kg, water 1500 kg, mix well and ferment. When the temperature in the heap reaches 60°C, turn it over, ferment for 15 to 20 days, then mix well with the soil, spray all kinds of bactericidal drugs without trace, spray and stir, and mix thoroughly to build a pile of plastic film before use. 2 hours to spread slightly dry.
Fourth, training materials formula and treatment (a) formula. 450 kg of dry fresh wheat straw, 50 kg of wheat bran, 10 kg of superphosphate, 2 kg of urea, 7.5 kg of gypsum powder, 5 kg of lime powder, and 2 bags of edible fungi three-dimensional nutrition essence (mixing type). (b) processing. Depending on the amount of raw materials for the cultivation, dig pits that are about 1 meter deep and 2 to 5 meters long and wide, with a wide plastic film inside, and put straw into it. In the process, the lime powder can be spread layer by layer. Finally, a layer of plastic film is laid on top of the wheat straw, and the earth or straw is piled up around to make it a concave shape. After filling the water to press down, the water pipe is moved. To the straw underneath the bowl, continue to fill the water. Because of the pressure of the water in the upper bowl, the wheat straw will not float. Soak all the grass in the water, and soak for a day. The wheat bran, superphosphate, and gypsum powder are mixed and the urea is dissolved in water and sprayed, so as to fully mix. After the wheat straw is soaked, it is not necessary to drain, and the above auxiliary materials can be mixed well. Then, the edible fungi three-dimensional nutrition essence is dissolved in about 15 kg of water, and the above materials are sprayed, mixed while spraying, and mixed well.
Fifth, the bed planting cultivation beds on the bed soaked with water in advance, broadcast a layer of bacteria before the spread of the material, the sowing amount is about 30% of the total amount of seed, the culture material is laid on the thickness of about 20 cm, slightly compacted The surface is then broadcast with a layer of the same amount of bacteria, covered with a layer of plastic film, but should not cover pressure, it is best to insert a wooden rod 20 to 30 cm high on the bed base at intervals of about 30 cm, hold up the plastic film, To increase oxygen content. According to the temperature of the greenhouse and the situation of germs, after 5 days, a layer of culture material of about 20 cm was added. After slightly compacting, the remaining strains were sown on the surface of the culture material and covered with the same film. After 2 days, remove the plastic film and cover the soil. Usually, the soil thickness is about 2 cm. Note that at the edge of the bed base, no material should be covered with a soil thickness of at least 8 cm to make it higher than the work track.
Six, bacteria stage management to maintain the temperature within the shed 28 °C ~ 34 °C, the humidity in the shed is about 90%, adhere to the evening and night ventilation, when the outside temperature is too high, spray water to the roof grasshoppers, irrigation water irrigation to cool . Spray the bactericidal drugs such as traces of the disease to the wall, the import and export, the vents and the free space every 3 days or so. Take care not to spurt the spurs until the end of the mushrooming. Generally 5 to 7 days can bud.
Seven, fruiting stage management to reduce the temperature within the shed as much as possible, so that the temperature is maintained at about 30 °C, the humidity within the shed can be maintained at 90% can not be too high, adhere to the night ventilation. When the fruit body grows to a small egg shape and the coating is still firm, it should be harvested in time. Pay attention not to injure the surrounding young mushrooms while harvesting, and to remove the mushroom feet and fill in depressions. After harvesting a tidal mushroom, it can be used to clean up the sorghum noodles and water it with the edible mushroom three-dimensional nutrition essence 2000 times. It is generally about 3 kilograms per square meter. After 7 days, it is budding again. The above management can be repeated.
