First, do not revive after inoculation, eating slow (1) reasons: 1 the original species or cultivation bag was not cooled after sterilization, the temperature above 30 °C, inoculation block into the bottle or bag, due to high temperature and loss Live or reduce vitality. 2 The inoculation tool was inoculated immediately after the flame of the alcohol lamp was burned, and the bacterial seed pieces were burned. 3 improper formulation of culture materials, adding too much lime, PH value is too high, because the alkaline is too large to eat. 4 The culture material is too dry or the culture temperature is low and the feed is slow. (5) The proportion of coniferous or poplar wood in the culture medium is large, and the oiliness of the wood chips affects the eating.
(b) The solution The method to solve the above problem depends on the cause of the problem. To strictly select the wood chips, the wood chips should be spread in the home for 1 to 2 days in order to distribute the oil and moisture and kill the bacteria. In the original seed formulation, it is generally not necessary to add quicklime; when the cultivar is produced, the amount of lime may be less than 0.5% due to a large amount, but the PH value cannot exceed 8. Moisture should account for 60% to 65% of the total weight of the ingredients. The material is too dry to eat, and the material is too long for the hyphae to grow. When inoculated, warm-reading inoculation has the effect of fast-acting bacteria, but the material temperature must fall below 30°C. After the inoculation tool is burned by the alcohol lamp, it should be cooled and then vaccinated to avoid burning the bacteria.
Second, bacterial contamination (a) reasons: 1 sterilization is not complete. Incomplete sterilization often occurs with large areas of contamination, sometimes full of pollution. The main reason is that: the pressure cooker leaks, the temperature is difficult to reach 100 °C; sterilization time at 100 °C temperature less than 8 to 10 hours; pot body design is not appropriate, there is a dead end of the airflow. 2 Inoculation is not standardized. To strengthen aseptic operation. No matter if it is an inoculum box or a console, there is still a small amount of bacteria in the sterilized treatment. Therefore, during the operation, the hand and the operation surface should be wiped with alcohol cotton; the mother and the original species of bottle, inoculation tools, and tampon should be moderately grilled under the alcohol flame; the action should be quick and accurate. 3 tampon, wet. The tampon is too loose, and the inoculated bacteria can enter the bottle (bag) from the gap. The tampon is too wet to stain itself and enter the bottle (bag). 4 Environmental pollution. The environment of the cultivating room may include bacteria in bed frames, spaces, ceilings, floors, and walls. Humid rooms and old chambers often cause bacterial contamination. 5 mother and original species with bacteria. The parent species and the original species with bacteria are non-negligible factors of bacterial contamination, resulting in cross-infection and easily causing significant losses.
(B) the solution: the sterilization is the primary issue for seed production. To ensure that the sterilizer quickly warms up, make sure to raise it to 100°C for 1 hour. Packing the cultivation bag should be sterilized as soon as possible to prevent bacteria breeding in the bag. To ensure the sterilization time, keep at 100°C for 8 to 10 hours. Sterilization personnel should prevent cooling in the middle.
Inoculation personnel must strictly follow the aseptic procedures. When sterilizing, wrap the bottle (bag) mouth to prevent it from getting wet. After the pan is used, the four-layer gauze bag of lime is gently pressed at the outer edge of the tampon to prevent the growth of the bacteria in the tampon and bottle mouth.
Keep a clean environment when inoculating. The strains were fumigated before entering the room; the bedsteads were kept dry. Always pick out contaminated bacteria bottles (bags) to prevent cross-infection. Contaminated bacteria bottles (bags) should be burned or buried.
Precise selection of the mother and the original species before inoculation. Pay special attention to the tampon and the mouth of the bottle, as long as there is a slight pollution can not be used for inoculation.
Prevention of pollution should be comprehensively managed and prevention should be the main focus. As long as the various junctures are good, the pollution rate will be greatly reduced.
Bag-growing common problems in the production process of black fungus original species and cultivars and their solutions
Bag cultivation of black fungus is a very good enrichment project developed in recent years in the eastern mountainous region of Jilin Province, which brings considerable economic benefits to growers. In the production process, the production process of the original species and cultivars often fails to rejuvenate after the inoculation, eat slowly and contaminated with bacteria, causing great losses in production. In practice, we have explored and studied the causes and solutions to these problems.
