Cultivation of Pleurotus ostreatus by Super High Yield of Bean Straw

Using bean stalks to cultivate Pleurotus ostreatus can effectively reduce costs and increase efficiency. According to the experiment, using bean straw as raw material and using super high-yield cultivation techniques combining bag planting and wall planting, the biological efficiency can be stabilized at about 200%, and the highest can reach 300%.

1, preparation of culture materials: use fresh dry no moldy bean straw, sun exposure 2 to 3 days, with a mesh hole size of 1 cm pulverizer. The formula is: 78 kg of soybean meal, 10 kg of wheat straw, 5 kg of bean cake, 1 kg of gypsum, 3.5 kg of superphosphate, 0.5 kg of urea, 2 kg of corn flour, and 130 kg of water. After mixing the cultivating material, it is piled and fermented, and it can be used for cultivation after turning 3 times.

2. Prepare nutritious soil: Use fertile garden soil 65 kg, sieve slag 20 kg, mixed wood or straw powder 10 kg, lime 3 kg, superphosphate 1.5 kg, urea 0.5 kg. Mix the first three kinds of main materials first, then dissolve the lime, phosphorus and nitrogen fertilizers into water, and pour them on the dry materials, and adjust the humidity in several grades.

3, bagging inoculation: the fermentation of good culture materials spread out to cool to below 30 °C, into a 22 to 25 cm 50 cm plastic bag, two layers of material three strains, at both ends of the bag mouth with bacteria Cover the surface of the plant and inoculate 15 kg of bacteria per 100 kg of dry material and tie the bag.

4. Fungal bag management: 10 to 15 days after sowing, the mycelium has grown vigorously, then each bag can be used to pin 8 to 10 micropores to supplement the oxygen needed for mycelium growth and accelerate its growth, about 20 ~ 25 days mycelium can be filled with the entire bag.

5. Bagging Wall: 7 to 10 days after the mycelium is full, enter the reproductive growth stage, unwind the two seals, turn the film from one end to the other, and then place the two ends of the opening into rows. Two rows, 3 to 4 cm apart in a row, fill 1 to 2 cm thick with a nutritious soil, and then discharge the second double bag, so that the layer of fungus bag is covered with clay and 6 to 8 layers. The uppermost layer of soil is 8 to 10 centimeters thick, and it is made into a groove type with a width, and garlic can be planted in the groove to prevent soil from being hardened.

6, fruiting management: After the bacteria wall is completed 5 to 6 days began to spray water mushroom. The tide mushroom bioconversion rate is about 100%. After the first tidal mushroom is harvested, the irrigation solution is combined with irrigation water in the tank: 1 kg of superphosphate and 0.5 kg of urea are added per 100 kg of water, and 4 to 5 tides of mushrooms can be collected.

7, split wall planting: mushroom walls after the mushroom 4 tide, you can dismantle, peel off the plastic film, the unwrapped one up, put upright in Yangshuo, fill with real soil bacteria bar clearance, irrigation Water-dampness bacteria sticks, coating management, can also harvest mushrooms 3 to 4 tides, in order to achieve the purpose of super-high yield cultivation.
