What technical points should be paid attention to when growing Pleurotus ostreatus indoors?
Pleurotus ostreatus is welcomed by people because of its delicious taste, short production cycle and easy cultivation, especially in Northeast China, where the climate is cold in winter and spring and fresh vegetables are scarce. If Pleurotus ostreatus is planted indoors and supplied to the market, it is a good way to get rich. But indoor cultivation of Pleurotus ostreatus, a prominent problem is that the air temperature is not easy to control, the surface layer of the culture material is easy to dry, affecting the production of Pleurotus ostreatus, the author thinks that the effect of covering soil cultivation is good through repeated experiments.
1. Mushroom selection. Mushroom can choose abandoned or temporarily unused houses (must be repainted with lime water), and have heating and ventilation facilities. Bedstead is set indoors, bedstead layer distance is about 60cm, and the lowest layer is 20~30cm away from the ground. Can also be used box or potted plants. Every cubic meter indoor fumigation with 10ml formaldehyde and 5g potassium permanganate mixture.
2. Ingredients and sowing. Raw materials can be selected from sawdust, wheat straw, rice straw, corn cob, corn stalk, bean stalk, etc., and some nutritional raw materials need to be added, prepared according to the general method, and disinfected (generally, when preparing culture materials, 1/800 carbendazim can be added to effectively inhibit the growth of miscellaneous bacteria). Sowing can adopt hole sowing or layer sowing, after sowing, leveling and slightly compacting, covering a layer of paper on the material surface and plastic film under the paper to keep warm and moist. Sowing starts from the upper bed frame and goes down layer by layer. The whole process must be strictly disinfected.
III. Management. After sowing, keep indoor temperature at about 24℃ and humidity at about 70%. Check the temperature of the material every day. If it is higher than 25℃, the film should be opened and ventilated to cool down. Bed temperature should be kept at about 24℃. When hyphae grow to 2/3 of culture medium, soil can be covered.
4. Cover soil. Peat soil is the best covering soil. Clay can be used without peat soil. The covering soil should be wet, and the pH value should be adjusted to 7~7.5 first, and then covered on the material surface. It can also be covered with dry soil directly and sprayed with water after covering. The suitable thickness of soil covering is 2~3cm. After covering soil, strengthen management, keep soil moist, increase ventilation, gradually reduce the temperature of mushroom house to 15~17℃, and keep humidity at about 90%.
5. Mushroom production and harvesting. After budding on the bed surface, remove the film, strengthen ventilation and light transmission, control the temperature and keep the soil surface moist. Pleurotus ostreatus can be harvested after growing up. Doors and windows should be opened for ventilation when harvesting. After picking mushrooms, the bed surface should be tidied up, the water should be stopped for 4~5 days, the mycelium should be restored to grow, and then the water should be sprayed to keep the bed surface moist. About a week or so, the mushroom bud can grow again. This is generally available in 3 batches of mushrooms.

Cultivation techniques of Pleurotus ostreatus in Taiwan
Taiwan Golden Pleurotus ostreatus, also known as Taiwan Golden Pleurotus ostreatus, with golden color, delicate taste and strong flavor, is a delicious edible fungus that sells well in Taiwan, Europe and the United States. 1. The optimum temperature of Pleurotus ostreatus in cultivation season is 13 ℃ ~ 24 ℃, and it takes 40 ~ 45 days from sowing to mushroom production. It is generally sown from February to March in spring and mushroom from April to May, from September to October in autumn, from October to December in winter, and from January to March in winter. Second, the cultivation site should be selected with clean environment and topography

There are wonderful ways to control moisture and increase yield by growing Pleurotus ostreatus indoors.
Humidity control is the key to success in growing Pleurotus ostreatus indoors, especially after mushroom production. At this stage, if the humidity is too low, it will make the mushroom body dry and shrink, or even die; if the humidity is too high, it is easy to rot mushrooms. Practice has proved that it is difficult to control humidity by spraying water, and sometimes the development of bacterial buds is affected due to excessive spraying of water on the material surface, resulting in the death of young mushrooms and the reduction or extinction of production. This paper introduces a wonderful method which can not only control the humidity but also increase the yield of Pleurotus ostreatus without spraying water. Get some cotton cloth and canned bottles and cut the cotton cloth into 8cm × 40
