High-yield planting techniques of Pleurotus ostreatus

Flower mushroom is produced by Lentinus edodes stimulated by certain specific environmental conditions, with a natural incidence of 40.5%. The production process does not use pesticides, fertilizers and any hormones, is not subject to any pollution, and can meet organic food standards. it is deeply welcomed by people at home and abroad for its rich nutrition and disease prevention, fitness, anti-aging and other functions. Let's take a look at the high-yield planting techniques of flower mushrooms.

Mushroom shed construction

Choose sunny, ventilated, flat terrain, dry soil, convenient access to materials to build east-west mushroom shed. The mushroom shed is 6 meters long, 2.6 meters wide and 2.4 meters high. three walls are built at both ends and in the middle of the mushroom shed, with an arc at the end of the wall, with a door 2 meters high and 0.6 meters wide in the middle, and a square exhaust hole with a side length of 12 centimeters above each end door. Bamboo pole is used as a layer shelf, 8 in each layer, with a total distance of 33 cm, with a total of 6 layers, which can put 500 bacterial bags, and the shelf is covered with wide film.

Planting time

Pleurotus ostreatus is divided into spring planting, autumn planting and winter planting, generally planted in autumn, Lentinus edodes produced at this time are mostly Lentinus edodes, with good economic value. The daily average temperature of 26-28 ℃ can meet the temperature requirements of Lentinus edodes mycelium. After 60-70 days of growth, the mycelium can be full of bags, and then after 10-15 days, the color can be changed. General November mushroom, before the Spring Festival can produce 2 tide flower mushroom, after the Spring Festival out of 1 tide flower mushroom, 1 tide thick mushroom, 1 tide thin mushroom.

Nutrient preparation

Take oak and fruit wood sawdust as main materials, crop straw (soybean stalk, cotton firewood), wheat bran and quicklime as auxiliary materials, in which sawdust is not less than 70% and fresh wheat bran is not less than 20%. When mixing, first pour sawdust and other main materials into the mixing plant, pile into a cone, then sprinkle fresh wheat bran and gypsum around the heap from the top of the heap, dry mix them for 2 to 3 times, and mix them evenly, then dissolve soluble additives such as sugar and potassium dihydrogen phosphate in water, pour them into dry materials for mixing, and mix materials to achieve "two evenness and one full", that is, all kinds of dry materials are mixed evenly, dry and wet evenly, and the raw materials absorb enough water.

Bagging sterilization

Using large bag cultivation, cut the 25 cm wide low pressure polyethylene plastic tube film into 55 cm long segments, then fasten one end with cotton thread, and then burn it with candlelight to melt into a small ball. Put the culture material into the bag, the loading should be loose and tight properly, after loading, tie the mouth with cotton thread and put it on the floor covered with gunny bags. The prepared culture material is required to be finished within 6-8 hours. Put the material bag into the atmospheric pressure sterilization stove, at the same time, put the coat bag with a seal at one end (58 cm long and 26 cm wide) and skimmed cotton into the steamer, leaving a gap of 20 to 30 cm high in the pot and burning it with high fire, so that the temperature in the pot reaches 100 ℃ in 4 to 6 hours, keep the temperature for 36 hours, open the pot after cease fire, leave the pot when the material temperature drops to 70 ℃, and transport it to the inoculation room.
