Technology of Pleurotus ostreatus under forest

First, to ensure the quality of strains, it is very important to master the correct production technology and ensure the good quality of Pleurotus ostreatus in order to achieve high and stable production. The variety we choose is Pinggao No.1. Practice has proved that the yield of improved varieties is more than 30% higher than that of inferior varieties, and the mushroom is strong, and diseases and insect pests rarely occur.

Second, the high-temperature Pleurotus ostreatus production site is selected as the woodland arch shed. The requirement is good ventilation and convenient drainage.

Third, the production of bacterial bags can adopt the method of making bags with clinker instead of raw materials. Clinker cultivation refers to the method that the culture material is sterilized at high temperature before sowing and sending bacteria. The cultivation of high-temperature Pleurotus ostreatus is the most suitable way, and its advantage is that after high-temperature sterilization, the nutrients in the material are fully decomposed, which is convenient for mycelium absorption and utilization; miscellaneous bacteria are not easy to occur in the germ period; and the material temperature can also be well controlled. The polypropylene bacteria bag is used, and the specification is 20cm × 45cm × 2.5mm 3 wire. The method of inoculation was hole sowing.

Fourth, the temperature of germ management is high in summer and it is difficult to cause bacteria. it is necessary to discharge bacteria bags reasonably, turn over bags and aerate oxygen in time, so as to control the temperature of bacteria and environment. The bacteria bag should be discharged in a single layer, with a distance of more than 50 cm, leaving a little space between the bags, shade and smooth ventilation in the bacteria-sending site, spray cold water to the bag if necessary, and control the bag temperature not more than 32 ℃.

Fifth, the mushroom management bag is full, there are yellow water droplets on the surface and when the primordium appears, the mushroom can be piled up. The fungus wall has up to three layers, leaving a 2 cm gap between the bag and the bag to dissipate heat, and the layers are separated by small bamboo poles. Soil cover cultivation in the forest: cut bag 1 to 2, distance 5 to 8 cm, cover soil 2 to 3, leave bag mouth plastic tube to moisturize and show bud; also can be flat cover, completely take off bag, distance is slightly larger, pour a lot of water, cover with 2-3 cm granular soil, cover with film to moisturize, wait for mycelium to grow full. Can also cover a layer of straw, moisturizing, breathable, and the growth of mushrooms are relatively clean. When the shading effect is not ideal, you can set up a sunshade net or grass curtain. Forest cultivation should use high-density north-south woodland, few light, good ventilation, the best row spacing is 2.5-3 meters.

The whole process of mushroom production should be well ventilated. In order to ensure humidity, water should be sprayed frequently, 3 or 4 times a day, and can be irrigated with heavy water every few days to ensure the humidity needed for the normal growth and development of the fruiting body. Avoid cold water when the mushroom is young, and the mushroom bud will catch a cold and draw it back, so pay attention to ensure that the water temperature is consistent with the ambient temperature.

High temperature Pleurotus ostreatus from inoculation to mushroom production, the time is very fast, normal management, mushroom can be produced in more than 20 days, and the bioconversion rate can reach more than 150%.
