New Techniques for Cultivating Pleurotus ostreatus

Pleurotus ostreatus is smooth, tender, nutritious and is the edible mushroom most commonly consumed by consumers. It is also the most widely cultivated mushroom with the largest annual production. However, in recent years, the price of Pleurotus ostreatus has been extremely unstable, and the price of Pleurotus ostreatus has been greatly reduced in the season when Pleurotus ostreatus is most suitable for growth. In such a fiercely competitive market, it is necessary to reduce the pollution rate and increase the output if we want to ensure that we do not lose money and make more money. . So what method can improve the yield of Pleurotus ostreatus fermentation material and reduce the pollution rate? Next, I will introduce a method to reduce the pollution rate and increase the yield by combining the fermenting agents of the Golden Baby edible mushroom cultivation materials.

Cultivation formula

300 kg of cottonseed skin, 300 kg of sawdust, 220 kg of corn cob, 180 kg of bran, 2 kg of slaked lime, and one kilogram of starter of Jinbao edible fungus

First, the fermentation of cultivation materials

1. Preparation: According to 0.1% of the weight of the culture material (that is, one thousandth, if the waste is reused, it can be added according to 0.2%). Prepare Kinba edible mushroom culture material fermentation aid; Ingredients to be crushed or cut off in advance Soak or shower pre-wet, adjust the water to 60-70%, PH value of 8 or so. The low water content is not conducive to the rapid propagation of functional microorganisms, and the slow fermentation speed. If the water content is too high, not only the temperature rise is slow, but also the local anaerobic environment may be caused by the poor ventilation, so that the "corrupt bacteria" breeds and produces odors. Whether water is suitable or not is determined by grasping a handful of material, see the watermark but not dripping.

2. Mixing: Using fresh rice bran (Note: "Mi Fu" is not "Reunion"), rice bran has good nutrition and air permeability, and old rice bran or untied tendon has poor nutrition; both are unfavorable; there is no bran available for bran or Replacement of corn meal) Dilution of fermentation auxiliaries (5 kg of rice bran per kilogram of gold baby fermentation aid), and then mix the diluted golden baby's fermentation auxiliaries with pre-wet bran, cake, manure and other accessories Evenly, then evenly mix in the main ingredient.

3, stacking: the raw materials of the culture materials are mixed evenly, according to the conventional heap system, piles with a diameter of about 10 cm evenly punched rods ventilation, and covered with sacks, straw curtains and other breathable coverings, in order to heat, moisture .

4. Toppling: When the material temperature rises to about 65Â°C, it can be tipped over for the first time and it can be turned over again in 3-4 days. The interval between the bisporus piles is slightly longer.

5, temperature control: the initial temperature of fermentation may quickly rise above 70-75 Â°C is normal, but should immediately fall over, can not maintain a high temperature above 75 Â°C for a long time, otherwise it will cause a large loss of nutrients in culture, affecting production. In the later period, according to the different requirements of the temperature of different edible fungi, take measures such as removing the cover, increasing the density of punching holes, replenishing the water, reducing the height of the pile, and tipping over to control the temperature within an appropriate range.

6, humidity: With the sharp rise in the temperature of the material pile and the continuous accumulation of heat, moisture in the material will be a large number of evaporation loss, it is also overturning, but also according to the specific circumstances of timely water (filling 0.5% lime water is better ) The last time the water supply and the turnover should be completed at the same time. When sowing, the â€œraw waterâ€ should be avoided as much as possible so as not to cause the strain to â€œnot eatâ€ after sowing.

7. Cultivation materials need to be fermented for about 5-6 days; Agaricus bisporus needs about 10-15 days. The fermented and decomposed culture material has a moisture content of about 65%, generally brown, and the surface is covered with white hyphae. There is no aroma smell of ammonia, and it is not sticky and flexible. The straw straw is lightly pulled, indicating that the fermentation is completed.

Second, bagging inoculation

The fermented cultivating material was put into a 22*45 cultivation bag and inoculated in a clean environment.

Third, the bacteria

The general culture needs to be in a dark environment with a temperature of 25Â°C, a humidity of 60%, and a time of incubation of 35 days.

Fourth, mushroom management

Pleurotus ostreatus need scattered light, the optimum temperature is 20-25 Â°C, the optimum humidity is 80-95%, the concentration of carbon dioxide is not easy to exceed 5000ppm.

V. Harvesting

When harvesting should pay attention to should be taken under the root, so as not to affect the lower tide mushroom.

The golden baby edible mushroom fermentation agent can shorten the fermentation time and solve the serious problem of nutrient waste in the fermentation process, and can make the fermentation more uniform and more fully, thereby reducing the contamination rate of mushroom cultivation, increasing the output of edible fungi, and increasing the production and income.
