The formation of the fruiting body of Pleurotus ostreatus is closely related to the environmental temperature, humidity, ventilation and light. Therefore, in order to obtain high quality and high yield, it is necessary to master the management points of the growth and development stages of the fruiting bodies of Pleurotus ostreatus. And strictly follow this point to manage.
1. The temperature management shows that the formation of primordial primordium needs a temperature difference of around 10°C. In order to get crisp and crisp mushrooms and produce high yields, we must first create temperature conditions. In spring and autumn, the natural temperature difference is large, and it is not necessary to create it. Many mushroom farms and mushroom farmers now have higher economic benefits in order to seize the market for fresh mushrooms in the summer. Have developed summer high temperature and back-season cultivation of mushrooms. However, in order to obtain the high temperature and high yield in the off season, it is necessary to create a suitable environment for low temperature stimulation. Therefore, any mushroom farm that prepares mushrooms for the hot season should establish a small refrigerator. The volume of the library can be determined based on the amount of cultivation. May be big or small. This small cold storage can be used as a place where mushroom bags produce low temperature stimulation. It can also be used as a fresh-keeping storage of mushroom mushrooms. Kill two birds with one stone. The operating procedure for the temperature difference stimulation using the cold storage in the hot season is as follows: Each day a mushroom bag is placed into the cold storage room for temperature difference stimulation. First of all, the already ripened bag is placed in a turnover basket, and the code is placed in a cold storage. The storage temperature is reduced to about 8-10°C as soon as possible, and it is maintained for about 10 hours. Generally, it can be stored in the library every day in the afternoon to handle one night. The next morning, the library will go out into the mushroom room. In the afternoon, the mushroom bag in the second mushroom house went into the cold store to continue processing. By analogy, cycling can effectively increase the utilization of cold storage and improve work efficiency.
After the temperature-stimulated bacterial bag enters the mushroom room, the room temperature should be kept within about 15-25°C in accordance with the outside temperature. Temperatures below 10°C must be warmed up. Above 30 °C, we must actively take measures to reduce the temperature, through the ground watering, space spray and spray water at the roof, shade the top of the net and other measures to cool down. Another point that needs special attention is that the mushroom needs a temperature difference during the mushrooming stage, but once a mushroom bud is formed, there is no need for a large temperature difference, otherwise it will cause the death of the mushroom bud. Therefore, once a mushroom bud is formed, it is necessary to keep the mushroom house at a constant temperature as much as possible. Therefore, if you want to mushroom in the cold season, mushroom house must have warming facilities. However, we must pay attention to the warming of the combustion exhaust gas must be discharged through the flue house, so as not to cause carbon monoxide poisoning caused by dead mushrooms. The general temperature increase can be maintained at about 20°C.
2. The humidity management shows that Pleurotus citrinoporus grows quickly, with dense fruiting, rapid tide, and numerous times of tides. Therefore, the water consumption is large. In order to ensure the yield and quality, the relative humidity of the mushroom house and the moisture in the mushroom bag must be guaranteed. When the bag enters the mushroom room, the bag is cut along the collar and the plastic film is cut off. And scrape off the original aging strains or hypertrophy. At this time, the relative humidity of the air in the mushroom house keeps about 90% for 3-5 consecutive days. From the beginning of the mushroom, each pod should be replenished with water before each temperature stimulus. To the maximum. Combined with ground irrigation, air spray maintains air relative humidity between 85-90%. If the air relative humidity of the mushroom house is more than 90% for a long time, it will cause diseases. Generally in a suitable environment. The buds can appear in 3-5 days. Do not spray water directly on the mushroom bud at this time, so as to avoid death of the mushroom bud. After the extension of the fruit shank to 3-4 cm is reached, when the diameter of the cap is more than 1 cm, the spray can be used to spray the fruit body. Adhere to fine spray, spray. It is best to spray water in conjunction with ventilation. Try not to spray "closed water" to avoid excessive humidity. Insufficient oxygen causes disease. In short, the management of humidity and moisture during fruiting should be based on the principle of seeing water spray, seeing water spray, and being flexible. On sunny days, windy days spray more and less rain or spray. The temperature is much higher and the water is more ventilated. Low temperature water spray. Less ventilation.
3, air and light. Pleurotus growth has special requirements for air. The requirements for mushroom display show that the length of the mushroom handle is 5-7cm. The concentration of carbon dioxide determines the length of the stipe of Pleurotus ostreatus. In order to meet the market's requirements for the quality of the longer handle, it is necessary to appropriately reduce the ventilation and increase the concentration of carbon dioxide. This is achieved by properly controlling the microclimate CO2 concentration in the mushroom house. Therefore, during the growth of the fruiting bodies, appropriate reductions in ventilation are generally adopted, or membranes are used to separate the cells into small cells. Several bed frames, or walls of bacteria, are covered with membranes like mosquito nets. Then, according to the growth state of the mushroom shape, the degree of opening of the film is controlled. Practice has proved that the effect is still good. If the stipe is short, the cap is large. It is necessary to properly seal the film. On the contrary, if the stipe is too long, the cap is too small. It is necessary to loosen the film properly. Increase ventilation. However, the management of ventilation and ventilation must be flexibly controlled according to the growth status of fruiting bodies. It cannot be changed. Severe lack of oxygen in the mushroom house can also lead to disease. This must attract attention. There are many ways to control the oxygen in the mushroom house. For example, a semi-submerged mushroom house is used. Facilities that control the oxygen content at the factory facilities are all very good. Can be adapted to local conditions. Choose to use.
During the growth of Pleurotus eryngii fruit body, proper lighting is needed. Scattered light can induce primordial formation and differentiation, and no lighted fruit can not occur. Between 200-800 lux, the fruiting bodies grew normally. The light is too dark and easy to form malformed mushrooms. Light is too strong. Especially direct light will cause the fruit body to dry up. Or form a short shank and cover a large inferior mushroom. Therefore, the management of lighting should also be flexibly regulated according to the growth stage and growth state of the fruit body.
