Soil cultivation of Pleurotus ostreatus

Soil cultivation of Pleurotus ostreatus can reasonably adjust the nutrient composition of carbon and nitrogen in the culture material, make full use of natural conditions such as temperature, humidity, air and water, and create a suitable growth climate for Pleurotus ostreatus. By using this method, the survival rate of buds can reach 100%, the stalk becomes thicker, the cap becomes more, larger and thicker, the quality of Pleurotus ostreatus is good, and the yield is 5 times that of conventional cultivation mode, and the yield is as high as 5000 kg for every 15 hectares (1 mu). This cultivation method has the advantages of simple technology, wide range of raw materials, economy and practicality, and is very suitable for large-scale planting.

The scientific ingredient formula is 75kg cottonseed shell, 15kg sawdust (broad-leaved tree sawdust) or corncob (corncob to be broken), 5kg plant ash, 2kg high-quality aseptic soil, 125Muth135kg water.

Mycelial cultivation, after mixing the above raw materials well, you can carry out the loading and inoculation of conventional microporous cultivation, pay attention to tamping with small sticks when loading, inoculate at both ends and middle of the material and fasten the mouth of the bag. Pack the material bag and choose a well-ventilated, dry and aseptic place outside to cultivate it. Pay attention to cover the heat preservation, cover the film on rainy days, remove it after rain, keep the temperature at about 20 ℃, and check the pile regularly (usually once a week). If the outdoor temperature is low, it can also be cultivated indoors. The mycelium growth and contamination should be checked regularly and the material bags contaminated by miscellaneous bacteria should be removed in time.

Column cultivation after the hyphae are covered with material bags, soil cultivation can be carried out. There are two kinds of cultivation methods, namely, plastic greenhouse cultivation and mushroom room three-dimensional cultivation.

Plastic greenhouse cultivation: move the cultivated material bag to the plastic greenhouse, remove the film, and place it vertically in the pre-made mushroom bed, which is as wide as 100 cm, 35 cm deep and unlimited in length. There is a fixed gap between the strains. Fill and plug the gap between strains with adjusted 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 nutritious soil is evenly mixed and filled, water is used to water through the soil until the water does not seep. The exposed strain is re-covered with soil, then watered thoroughly (called small watering) in the part after filling, and then sprinkled with a thin layer of plant ash. After 24 hours, cover about 2 cm with fine soil to prevent moisture from spreading.

Three-dimensional cultivation of mushroom room: move the cultivated material bag to the mushroom room, remove the film, and place it horizontally on the border laid in advance with nutritious soil (the preparation method is the same as above). The width of the border is unlimited in length to be able to spread out two strains and leave a certain gap. Fill the gap with nutritious soil after filling a row, and then put a layer on it, and fill the soil to the appropriate height. Put another column according to the same operation, leaving some space in the middle as the operation channel, and then watering (operation as above).

During the period of mushroom production management, the relative humidity of the air in the shed should be kept at about 85%, and strong scattered light should be given, and the temperature should be kept at 8 Murray 20 ℃. After 10 days, the buds will break out one after another, and there is no need to spray water at this time. After the bacterial cap is formed, you can pour a small amount of water. The air in the shed must be kept fresh to prevent deformed mushrooms. When the bacterial cover grows to about 5 cm in diameter, it can be watered once. The management measures of three-dimensional cultivation in mushroom house are basically the same as those in plastic greenhouse. Attention should be paid to the control of air humidity, temperature and humidity of nutritious soil. After picking mushrooms once, water thoroughly every 3 days, and then cover the soil for management. Such a feeding can harvest 8 murmurs for 10 times.
