Pleurotus ostreatus high-yielding cultivation techniques

<

The traditional mushroom bag planting method, after two tidal mushroom mushroom bag serious water loss and fertilizer, and then use the soaking method of replenishment, supplement fertilizer, not only transport troublesome and time-consuming, but also difficult to control the water within the bag, water and fertilizer one-time supply of mycelium is difficult to absorb If the concentration of the nutrient solution is too high, reverse osmosis may occur in the moisture of the mycelium and produce a harm. Pleurotus ostreatus mushroom high-yielding cultivation technology has many advantages compared with the traditional bag planting method: First, the culture material and the air contact surface is small, reducing the pollution and water evaporation, avoiding the traditional Pouch method after the second mushroom high pollution rate The second is to eliminate the cumbersome process of transporting the replenishing water from the bag and greatly reducing the cost; third, the mycelium can selectively absorb nutrients from the soil through ion exchange, thus completely eliminating the direct The negative effect of replenishing water to the mycelia is difficult to absorb for a while; the fourth is that the mushroom body is clean and non-stick soil, with good quality and high selling price. Fifth, the long fruiting period, high yield, once cultivation can be harvested 6-7 tide mushroom. The specific cultivation techniques are introduced as follows:

Material selection and bagging. The conventional bag planting method is used to select materials, ingredients and spices. In winter, the temperature is low and raw materials can be used for cultivation. Take a 40 centimeter wide tube cut into 75 centimeters long, first bind the end of the tube into a bag, and use a bamboo tube with a diameter of 10 centimeters and a length of 40 centimeters to stand on the ground in the center of the bag. Then sprinkle a layer of bacteria in the bottom of the bacteria bag and then load the material. While loading the material to the side of compaction, when the material is loaded to a height of 10 cm, spread two rounds of bacteria to the periphery of the bamboo tube and the periphery of the bacteria bag. Two concentric circles of bacteria are formed. When the material is loaded to 20 cm high, the same method is used to sow a layer of bacteria. When the material is loaded to a height of 30 cm, the entire material surface is sprinkled with a layer of bacteria, and a bamboo tube is pulled out to tie the mouth of the bag to form a three-layer material four-layer strain 30 centimeters high.

Cultivation of mycelium. The culture room was previously sprayed with 2% to 3% of Lysol spray and sprayed with 40% dichlorvos 400-fold dilution insecticide and insect repellent. Afterwards, the doors and windows were closed for 24 hours. The next day, the windows were opened for ventilation and a layer of lime powder was sprinkled on the ground. The bacteria plate was moved into the culture room, and the bacteria was piled by the "product" shape. The code was generally 3-4 layers. When the temperature in winter is low, the temperature of the outer cover is increased. During the germination period, a 2%-3% solution of rosar was alternately sprayed into the air every 4-5 days for air disinfection. When the mycelium began to germinate, doors and windows were opened every morning and evening for 30 minutes. When the mycelium at both ends of the fungus plate is thick white and there are two thick white fungus circles in the middle, turn over and open a small mouth with a knife at both ends of the hollow. When the heap is rebuilt, the fungus disk is turned upside down. When stacking, the center hole of the upper bacteria plate is aligned with the gap between the bottom four plate plates to facilitate ventilation. The whole period of germination is about 35 days in winter, and the hyphae can be filled with bacteria bags. During this period, it is not less than 3 times.

The construction of stumps. After the mycelium has penetrated, the fungus plate can be moved into the mushroom house to construct the fungus column. Firstly unroll the bottom layer of the upper end of the disk, roll it around to reveal the entire upper bacterial surface, sprinkle a layer of fine fluvo-aquic soil about 1cm thick, and then roll the thin film on both ends of the several plates above. Surrounding, exposing the bacteria surface, then pressing the hole to face the hole face-up stacking 4-5 layers high, every two layers of the bacteria surface contact surface are covered with a layer of fine fluvo-aquic soil about 1 cm thick, and finally at the top of the mushroom column A fine fluvo-aquic soil about two centimeters thick is covered. The hole in the center of the stump is filled with fine moist soil. A pot-shaped water storage pit is formed in the center above the stump, and the stump is completed. In this way, a row of mushroom columns is built in the mushroom house, and the row spacing is easy to operate.

Mushroom management. After 3-4 days of construction, the temperature difference between day and night should be increased to sprinkle water on the walls and ground. The water in the storage pit of the mushroom column should also be filled with water to keep the air humidity above 90%, and the ventilation of the mushroom house should be enhanced. After another 4-5 days, a large number of primordiums can appear around the entire mushroom column. At this point you can control the number of mushroom clusters and mushroom size, in order to mushroom-shaped, you can remove part of the original base, evenly retained in the stud around a few strong primordium, the fruiting body grow into a large bundle of large leaves. To think of mushroom shape, as long as the original base grows strong, just cut a small mouth and let it grow into a fruiting body. During the growth period of the entire fruiting body, it is only necessary to keep the ground and the walls moist and the water in the pool is not dry, and it is not necessary to spray water on the mushrooms. After harvesting each mushroom, stop spraying water on the ground and walls. After the water storage pit is cut off for 2-3 days, it is filled with nutrient solution and kept dry. When the fruiting body grows again, sprinkle water on the ground and walls to keep it moist. This management can harvest 6-7 tidal mushrooms.
