In the raw material culture of Pleurotus ostreatus, the following points should be made in order to increase the yield and reduce the contamination of various bacteria:
First, to maintain environmental sanitation, no livestock and poultry are to be kept around the cultivation farms, no wood is stored, no garbage is piled up, no discarded culture materials can be thrown in, and the cleaning materials are often cleaned and kept clean. The culture materials contaminated with bacteria must be shipped out in time for deep burial. .
Second, it is necessary to change crops regularly: use existing cultivation sites and take turns. Regularly sterilized at the time of leisure, kept clean, the strain used should be replaced every 1-2 years, and it is better to rotate with different kinds of oyster mushrooms.
Third, we must select good strains, anti-pollution of Pleurotus ostreatus, bacteria, white thick, thick, strong wall climbing, was cotton wool, evenly distributed, the daily growth of more than 1 cm in length. Pay attention to the selection work, conditional selection of their own; unconditional introduction of contrast, determine the succession of bacteria.
Fourth, inoculation of bacteria of the right age should be selected. Inoculation with appropriate strains of bacteria should be rapid and have a strong tendency. It can prevent bacteria more effectively than increasing the inoculum size. Inoculation of 30 to 40 days of bacterial strains for low-temperature strains of Pleurotus ostreatus Well, medium-temperature Pleurotus ostreatus is 25 to 35 days old.
Fifth, we must purify raw materials. Strictly choose the material and use fresh, mildew-free culture materials. There must be plans for the purchase of materials, as well as for the production of their own products. Prepare raw materials as much as possible and use new materials year after year. The raw materials should be properly preserved, protected from rain, moisture, and heat. Before use, they should be sun-dried for 4 to 5 days. The day before cultivation, the materials should be mixed. Mixed with 1% to 2% lime water, piled, covered with plastic film overnight, both the material can eat water, as well as sterilization.
Sixth, we must scientifically deploy the matrix. After overnight stuffing, stir well and test for moisture and pH. The moisture was adjusted to about 65%, and the pH of the raw material was adjusted to 7.5. The source of raw materials for cultivation is insufficient, supplemented with soybean meal or urea, and wheat bran and cornmeal cannot be added.
Seventh, we must optimize management. Avoid high temperature season during germination. After the cultivation bag enters the culture room, the best growth conditions (24°C at room temperature, good ventilation and darkness) are promptly created, and the mycelium is promoted early and long. After the hyphae grow well, the room temperature is reduced to below 18°C ​​and the humidity is increased to 85% to 90%. Give scattered light of 200 lux or more to maintain good ventilation. At the same time, release the bag mouth, and puncture the buds to produce mushrooms. After the occurrence of mushroom mushrooms, rewind the bag mouth. During the management process, do not bump the fruiting body. Do not pick up the culture material with mushrooms. , The mushroom roots, debris and other net addition.
