Pleurotus high wall type cover soil super high yield cultivation
Pleurotus high wall type cover soil super-high-yield cultivation is to be out of 1 ~ 2 mushroom bag after bagging piled into a high wall, and use sterile nutrients to connect the bacteria, so that it repeatedly mushrooming cultivation methods. Using this method to cultivate Pleurotus ostreatus has the advantages of simple facilities, good heat preservation, low pollution rate, fast and concentrated mushrooming, excellent mushroom quality, high biotransformation rate, and convenient management, which can better solve the temperature of mushrooming The humidity is not easy to control and management is inconvenient, especially the problems of low yield and poor quality due to nutrient and water deficit after harvesting 3 tidal mushrooms, which can extend the mushrooming period by 2 months, and continuously harvesting 6-8 mushroom species. The bioconversion rate reached 250% to 300%, which was significantly higher than conventional cultivation methods. Prepare culture materials by mixing 100 kg cotton seed hull with 2% lime, 1% gypsum, 5% wheat bran, 0.2% carbendazim, and 130-140 kg of water. Mixing and composting for 6 to 7 days during fermentation. Pile 2 times, so that the material temperature is stable at 60 ~ 70 °C. After the culture materials are fermented, they are spread and dried. Preparation of nutritious soil Take fertile garden soil with 3 to 5 parts of plant ash, 0.5% urea mixture, while adding 1% carbendazim, can add 0.5% to 1% of superphosphate, heap boring 1 week standby. Preparation of nutrient solution Add 50 to 1 kg of magnesium sulfate and 0.2 to 0.3 kg of potassium dihydrogen phosphate per 50 kg of water; or add 0.5% of urea in 50 kg of water and a little solution of MSG. After harvesting the second tidal mushroom, the moisture and nutrients in the bag are deficient, and the nutrient solution and moisture can be supplied through the concave groove on the top of the mushroom bag pile. The fungus bag is sterilized with 50 grams of 40% sodium dichloroisocyanurate soluble powder per 100 kilograms of culture material, and packed for 24 hours. The bag size is 17 cm 45 cm or 22 cm 50 cm. The two ends of the sterilized bag are clamped with a paper clip, autoclaved for 3 to 4 hours or sterilized at normal pressure for 8 to 10 hours, and then inoculated at a constant temperature, and the inoculation amount is 8% to 10% of the dry weight. Will be a good type of bacteria bag neatly discharged in the dark, keep the bag temperature at about 28 °C, after 20 to 25 days mycelium can be made good. After harvesting 1~2 tidal mushroom, high wall type soil-covered cultivation was performed. The high-wall cover soil in the shed will be stacked in layers of 5 to 6 layers of stacked bacteria, the height of 90 to 110 cm, forming a wall of bacteria. The top of the block wall is made into a reservoir. The inside diameter of the pool is 16 to 18 cm and the height is 6 to 8 cm. The pool was drained, allowing it to slowly penetrate the wall of bacteria, keeping the relative humidity of the bacteria at 65% to 80%. Leave a 50 to 60 cm wide wall between the wall and the wall. After the bacterial wall is piled up, it is evenly sprayed with the pre-prepared nutrient solution, and the nutrient soil is used to seal the wall of the fungus and cover the membrane. After 1 week, the bacterial wall can be budded. Optimum temperature and humidity mushrooming temperature to 16 ~ 25 °C is appropriate, increase the temperature difference between day and night is conducive to the formation of fruiting bodies. The shape of the mushroom has a lot to do with whether the air is circulated or not. If the ventilation is poor and the concentration of carbon dioxide is too high, there will be malformed mushrooms such as long-leg mushroom. The humidity in the greenhouse is maintained at more than 80%. When budding, water is sprayed to the space and the ground, and water can not be sprayed directly onto the bud. When the mushroom covers 2 cent coins, it can spray water directly. Spray 1 or 3 times a day, the amount of water spray should not be too large, so as to avoid rotten mushrooms and dead mushrooms. In the winter, less water spray may occur, and in spring and autumn, the amount of water spray may be increased, and in summer, it may be sprayed more.
