Cultivation techniques of Pleurotus ostreatus

Pleurotus ostreatus is a kind of precious wild edible fungus, which is delicious and nutritious, and is widely loved by the public. Now many people are beginning to cultivate this fungus. Today, let's have a brief understanding of the cultivation techniques of red mushrooms.

Cultivation techniques of Pleurotus ostreatus

The main results are as follows: 1. As a mushroom farm cultivated in a fermentation bed, we should choose a field that rests on mountains and water, has fertile soil and is sunny and leeward. Border bed width of about 1.3 meters, the bed surface into a tortoise back shape, all around a good drainage ditch, built on the shade shed to maintain "three points of yang, seven points of shade" illuminance.

2. The inoculation methods of Pleurotus ostreatus are mainly divided into bag planting and bed planting.

① bag planting: when the temperature of the waiting bag dropped below 28 ℃, the strain of Pleurotus ostreatus was inserted into the culture medium in the bag under aseptic condition and sealed with cotton plug. After inoculation, it was transferred to 23-25 ℃ indoor bacteria culture, the air relative humidity was less than 70%, to maintain ventilation and prevent the sudden increase of indoor carbon dioxide concentration. Hairy bacteria culture is usually about 30 days. After the mycelium is full, move the bag to the field shade shed to remove the bag, discharge it horizontally on the bed in the pre-sterilized shed, and cover 3-5 cm of humus soil. Cover the border bed with soil and let the bacteria tube continue to be cultured in the border bed.

② bed planting: spread the fermentation material in the border bed, the material thickness is 15-18 cm, and sow seeds in three layers, that is, the border surface is first covered with a layer of family, sown with bacteria, continue to spread a layer of material, sow seeds, and then cover a layer of material to form three layers of material and two layers of species. Generally, 10 kg of dry material is used per square meter, and the amount of bacteria accounts for 10% of the material. After sowing, the material surface is leveled and compacted slightly. Then the arch cover is covered with film to protect against rain above the bed. When the mycelium is fed for 2 / 3, the soil is covered with 3-5 cm. However, attention should be paid to ventilation to keep the air in the border bed fresh and facilitate the development of hyphae.

3. The mushroom can be produced in about 20 days after covering the soil, and the temperature is controlled at 23-26 ℃. The artificial stimulation of temperature difference and alternation of dry and wet can promote the kink of hyphae to form primordia and differentiate into mushroom buds. In the fruiting body development stage, the film is ventilated and sprayed once every morning, and the space relative humidity is kept at 90%. Keep the air fresh in the mushroom shed.

4. The fruit body of wild red mushroom can be exploited with a maturity of 60 or 70%, and reasonable harvest is closely related to the commodity value of red mushroom. The market purchase price of medium's unopened red mushrooms is higher than that of fully mature ones. In general, overmature umbrella mushrooms or those that have shown signs of decay, the vast majority of them have eaten maggots and lost their commercial value. Do not harvest them, but should stay in the woodland as a breeding source, which is conducive to the growth of mushrooms in the following year.

The cultivation technology of red mushroom is briefly introduced here. I hope it will be helpful to everyone.
