Cultivation of Pleurotus ostreatus with bean straw bag wall

Using bean straw as culture material, Pleurotus ostreatus is cultivated by the combination of bag cultivation and wall cultivation, which can reduce the cost and improve the benefit.

Preparation of culture materials: dry and mildew-free bean stalks were crushed after 2-3 days of sun exposure. Culture material formula (by weight): soybean straw powder 78%, wheat straw 10%, soybean cake 5%, corn meal 2%, gypsum 1%, calcium superphosphate 3.5%, urea 0.5%. The culture material was mixed with 130 kg of water and then piled up and fermented for 3 times during fermentation.

Bag inoculation: disperse the fermented culture material and put it into a plastic bag with a length of 50 cm and a width of 22-25 cm when the temperature is below 30 ℃. Each bag is connected with 3 layers of bacteria. The material surface is covered with bacteria at both ends of the bag, and the mouth of the bag is tied tightly. The inoculation amount is 15 kg of bacteria per 100 kg of dry material.

Bag management: the mycelium grows vigorously 10-15 days after sowing, and 8-10 small holes can be stuck in the bag to get enough oxygen and accelerate the growth. After 20-25 days, the hyphae were filled with bacteria bags.

Prepare nutritious soil: nutritious soil formula (by weight): fertile vegetable garden soil 65%, sifted slag 20%, miscellaneous sawdust or straw powder 10%, lime 3%, calcium superphosphate 1.5%, urea 0.5%. First, mix the first three main materials evenly, then dissolve lime, calcium superphosphate and urea in water and pour them on the main material, and adjust the humidity step by step.

Take off the bag wall: 7-10 days after the mycelium is full, unlock the seal at both ends of the bag, roll the bag from one end to the other to half, then arrange the roll in two rows opposite to each other, the middle of the two rows of bags is 3-4 cm apart, the middle is filled with nutritious soil, the bag is 1-2 cm thick, and then discharge the second layer bacterial bag, such a bacterial bag, a total of 6-8 layers. The top layer of soil is 8-10 cm thick and is made into a band trough, in which garlic can be planted to prevent soil consolidation.

Mushroom production management: spray water to promote mushroom 5-6 days after the fungus wall is finished. After harvest, the nutrient solution was added in the tank combined with irrigation, and 1 kg of superphosphate and 0.5 kg of urea were sprayed in every 100 kg of water. Spray the nutrient solution once after each harvest, so that 4-5 tide mushrooms can be harvested.

Wall border planting: after 4 tides of mushroom, you can disassemble the bacterial wall, peel off the bacterial bag, put the unmushroom end upright in the sunny border, fill the gap between the bacterial rods with nutritious soil, then irrigate the bacterial rods thoroughly, and cover them with plastic film. After normal management, 3-4 tide mushrooms can be harvested.
