Pleurotus ostreatus soil cultivation can reasonably regulate the carbon and nitrogen nutrient components in the culture materials, and make full use of natural conditions such as temperature, humidity, air and moisture to create a suitable growth climate for Pleurotus ostreatus. By using this method, the survival rate of the buds can reach 100%, the stems become thicker, and the caps become larger, larger and thicker. The quality of the produced oysters is good, and the yield is 5 times that of the conventional cultivation mode. --10 mushroom, yield up to 5,000 kg per 1/15 hectare (1 mu). This cultivation method is simple in technology, wide in raw materials, economical and practical, and is suitable for large-scale planting. The scientific ingredient formula is 75 kg of cotton seed shells, 15 kg of sawdust (brass of broadleaf sawdust) or corncob (cob to be shredded), 5 kg of grass ash, 2 kg of high quality sterile soil, and 125-135 kg of water. After the above materials are mixed, the mycelia can be mixed and the conventional microporous cultivation can be used for inoculation. Pay attention to the use of small wooden sticks for tamping during filling, and inoculate and bind the bags at both ends and in the middle of the material. Put the packed bags on the outside and choose a well-ventilated, dry, sterile place for cultivation. Pay attention to cover the insulation, cover the film in rainy weather, peel it off after the rain, require the temperature to be maintained at about 20°C, and turn it regularly for inspection (usually once a week). If the outdoor temperature is low, it can also be cultivated indoors. The growth and contamination of mycelium should be checked regularly, and the bags contaminated with bacteria should be removed in time. After the cultivation of the mycelium, the mycelium is covered with a bag and the soil can be cultivated. There are two kinds of cultivation methods, namely plastic greenhouse cultivation and mushroom house three-dimensional cultivation. Plastic greenhouse shed for cultivation: The cultured material bag is moved to a plastic greenhouse, and the film is removed and placed vertically in a pre-made mushroom mushroom. The mushroom mushroom is 100 cm wide and 35 cm deep. Not limited to. There are certain gaps between the strains. Fill and fill gaps between strains with well-conditioned nutrient soil. The proportion of nutritious soil is: 98% of high-quality soil, 1% of plant ash, 0.5% of phosphate fertilizer, and 0.5% of lime powder. After the nutrient soil is well-mixed and filled, the soil is soaked with water until the water does not infiltrate. The exposed strains were re-sealed with soil, then soaked in the filled area (called a small watering), and then sprinkled with a thin layer of plant ash. After 24 hours, cover about 2 cm with fine soil to prevent water from spreading. Mushroom house three-dimensional cultivation: The cultured material bag is moved to the mushroom room, and the film is removed, and horizontally laid on the tweezers preliminarily covered with nutrient soil (the preparation method is the same as above), and the width of the tweezers is able to swing open two Strain and leave a certain gap, the length is not limited. After filling a row, fill the gap with nutrient soil, and place a layer on it again, filling it to the appropriate height. Place the other column in the same operation, leaving some room as an operating channel, and then water (operation same as above). During the period of fruiting management, the relative humidity of the air in the shed should be maintained at about 85%, and strong scattering light should be given, and the temperature should be maintained at 8- 20°C. After 10 days, the buds will come out one after another and there is no need to spray water. After the cap is formed, you can pour small water. The air in the shed must be kept fresh to prevent malformation. After the cap has grown to a diameter of about 5 cm, it can be poured once. The management measures using three-dimensional cultivation of mushroom houses are basically the same as that for plastic greenhouses, and the control of air humidity, temperature and the humidity of the nutrient soil should be controlled. After harvesting mushrooms for the first time, irrigate the water every 3 days and then cover the soil. This feed can be harvested 8-10 times.
