During the planting season from August to September, the natural temperature is high, and the high temperature above 30°C sometimes appears during the fruiting period; the temperature will gradually decrease after entering October. In order to ensure normal mushrooming during high and low temperatures, the selected strain must be Both high temperature, but also take into account the excellent varieties of low temperature mushroom. The strains of National Pingliang Variety and Qingfeng No. 1 have the above characteristics. If the type of temperature used is inappropriate, it is not suitable for early autumn cultivation. Care must be taken when introducing the species.
Second, culture material fermentation, sterilization should be "strict"
Pleurotus ostreatus has two methods of fermentation and clinker cultivation. When cultivated with fermented material, the fermentation period of the culture material shall not be less than 4 days. The temperature in the material pile must reach 65° C. or more, and the intermediate piles shall be 2-3 times, so that the raw materials will be cooked evenly to achieve the purpose of sterilization. With clinker cultivation, sterilization must be maintained at a temperature of 100°C for 8-12 hours (depending on the size of the sterilization vessel), or after an "induction pre-fermentation" technique, followed by high temperature sterilization, which is more effective . If the fermentation is not completely sterilized, it will be difficult to succeed.
Third, the regulation of temperature is the key period of germination
Pleurotus ostreatus cultivation and plastic bag cultivation of two kinds. The early cultivation of the mattress, first, the material thickness shall not exceed 15 cm, and the width of the carriage shall not exceed 1.2 meters; secondly, the middle of the carriage shall be longitudinally provided with a 20 cm wide ventilation ditch, which is conducive to ventilation, cooling, and cooling. The temperature of the materials is adjusted; the third is the use of two layers of sowing to increase the seeding rate so that the mycelium quickly covers and grows inside the material; and fourthly, within 10 days after sowing, the material temperature must be checked, if the material temperature exceeds 32°C, Prompt ventilation and cooling. Otherwise, it will lead to high-temperature burning bacteria, mycelial viability will decline, and various bacteria and other competitive bacteria will be produced in large quantities, resulting in reduced production or failure.
Fourth, plastic bag cultivation
Whether it is a clinker bag or a fermented material bag, the bag is best placed in a single layer after sowing. There must be a 2 cm gap between the bag and the bag. Pay attention to ventilation to keep the temperature inside the bag 32°C. In particular, fermentation materials, but not to the effect.
