Mushrooms belong to the high temperature type of fungi, wild red mushrooms occur in summer. The mycelial growth is suitable at 20°C-25°C, and the fruiting temperature is 23°C-28°C. The cultivation season is spring inoculation and summer fruiting. Usually inoculated in May, mycelium culture 45-50 days, from late June to July long mushroom, 70 days in advance for the production of the original species and cultivars.

The raw material selection of Pleurotus ostreatus belongs to the grass-soil indigenous fungi, which are mainly used to decompose manure and grass organic matter as the main nutrient for reproduction. The wild red mushroom fruit body was born on moist, rich organic matter in the forest. The substrates are decayed stalks, weeds, leaves and livestock manure. The cultivation raw materials of red mushrooms are preferably cellulose-rich crop stalks, such as cottonseed hulls, cotton stalks, bagasse, soybean stalks, corn cobs, corn stalks, sorghum culms, and reeds on the mountain, swampweed, elephant grass, jiaomang, etc. Weeds can be used.

The preparation of red mushrooms by culture materials requires more nutrients, and it is advisable to prepare synthetic culture materials. Here are some recipes for selection. Formulation 1: 86% cotton seed hull, 8.5% wheat bran, 2% lime, 1% calcium carbonate, 2% superphosphate, 0.5% urea. Formula II: 48% soy bean straw, 20% peanut shell, 19% cotton seed hull, 10% wheat bran, 1% calcium superphosphate, 2% calcium carbonate, and the ratio of feed water is 1:1.3. Formulas 1 and 2 are mainly used for clinker bags. Formula 3: 90% cottonseed husk, 6% wheat bran, 1% lime, 1.5% superphosphate, 1% calcium carbonate, 0.5% urea, and 1:1.3 ratio of feed water. Formula 4: 50% of reeds, 16% of mixed wood chips, 30% of cotton seed hulls, 1.5% of lime, 2% of superphosphate, and 0.5% of magnesium sulfate. The feed water ratio is 1:1.3. Formulations 3 and 4 are suitable for bed planting of fermented material.

Red groceries cultivation clinker bag planting and fermentation material bed planting, the two cultivation methods are different, the culture material production is also different: clinker cultivation in accordance with the formula one or two, the cultivating mix, the water content at about 60%, and then Put into a 1733-35 cm polypropylene plastic bag, autoclave, and cool inoculate (as required). Fermentation material bed planting: According to the recipe 3 or 4, the culture material is mixed and mixed, and concentrated into a pile of fermentation treatment. The stock stack is 0.8 meters high and 1 meter wide. The length depends on the site. After the material is piled, the cover film is moisturized. The fermentation time is 5-7 days. When the material temperature reaches 65 DEG C, it starts to turn and the middle pile turns 2-3 times.

Inoculation and cultivation methods are different, and inoculation and cultivation methods are different. Bag planting: When the temperature of the bag falls below 28°C, the sterilized mushroom strain is inserted into the culture medium in the bag under aseptic conditions and the tampon is sealed. After inoculation into the indoor bacteria culture 23 °C -25 °C, the relative humidity of 70% or less, to maintain air circulation, to prevent sudden increase in indoor carbon dioxide concentration. Fermentation culture usually takes about 30 days. After the mycelium is fully bagged, the bag is taken out of the shade in the field and taken out of the bag, horizontally discharged into a previously sterilized shed on a shed, and covered with 3-5 cm of humus. The trampoline was covered with mud and the fungus tube was cultured in the trampoline. Bed planting: spread the fermented material in a trampoline, 15-18 cm thick, sowing in 3 layers, that is to say, firstly lay a layer of crops, sow the strains, continue to lay one layer of material, sow one layer of seed, then Then cover one layer of material to form three layers and two layers. Generally, 10 kg of dry material is used per square meter, and 10% of the amount of material is taken as the amount of bacteria. After sowing, the material level is leveled and the material is pressed slightly. Then on the side of the trampoline is a thin film of arch protection against rain. When the mycelium eats 2/3, cover the soil 3-5 cm. But pay attention to ventilation, so that the trampoline air fresh, in order to facilitate the development of mycelium.

Mushroom management After the fungus bag enters the field, it should be kept moist in management. Soil moisture content of not less than 20%, field soil moist, generally do not have to spray water, such as the climate is dry, the surface whitish water spray moisturizing, but can not be infiltrated into the material, so as not to mycotica. Generally about 20 days after covering the soil, the temperature can be controlled in the range of 23°C-26°C, and artificially changing the temperature and stimulating, altering wet and dry, promoting the formation of kinks of mycelium and differentiation into mushroom buds. In the mushroom shed, “three points of yang and seven points of yin” are required. The development stage of fruiting bodies is to remove membranes and ventilate every morning, and combine water sprays once. The relative humidity of the space should be kept at 90%. Fresh air inside the mushroom shed. The temperature is in the 23°C-28°C range.

The fruiting period is in the hot summer season, and the wild red mushroom grows under the dense forest. The temperature is lower than the space. For this artificial cultivation in the case of high temperatures, water spray should be used to reduce the space temperature, sulcus and ditch water storage to lower ground temperature, thicken roof coverings, resist external heat sources, artificially created suitable long mushroom environment. If germs are found to be contaminated during the fruiting stage, the affected parts should be dug out in time and sprinkled with lime powder. After 1-2 days, the new soil should be covered and ventilation should be strengthened to keep the air fresh.
