Widening bag cultivation to narrow bag cultivation Many people believe that it is better to use a 25-centimeter-50-cm plastic bag tube to cultivate Flammulina velutipes, but wide bags are susceptible to miscellaneous bacteria, and when the number of mushroom buds is small, the fruiting body is easy to bend, which affects the quality and cannot reach quality. Cover small handle, light color, fat tender high quality requirements. Therefore, it is better to use a 17-cm 33-cm plastic bag.
The autoclave was modified to be a natural defect type of vitamin B1 and B2 that was sterilized at normal atmospheric pressure. On cultures rich in vitamins B1 and B2, they grow rapidly and have a low number of spores. However, vitamin B1 is not heat-resistant and readily decomposes at temperatures above 120 degrees Celsius. Therefore, the culture medium should be sterilized at normal pressure. However, in order to ensure the pure bacteria rate, the sterilization time can be extended from 10-12 hours to 13-18 hours.
When changing the traditional vertical mushroom to two horizontal mushroom fillings, inoculate and leave about 15 cm of tube membrane on both ends, gently install the pressure and tie the bag. Horizontal display about 4 layers of bacteria. This method can ensure the quality of mushrooms, but also can save the mushroom room area, can increase the output per square meter of mushroom house more than 30%.
Changed the bag to a one-time solution for control of the closed bag. The oxygen concentration in the bag is low. If the hyphae spit out the yellow bead and then unwrap the bag, it will inevitably affect its growth. Therefore, we must always pay attention to the growth of mycelium in the bag. Once the growth of mycelium in the bag is found to be slow, we must promptly unpack the bag. But at this time, do not all open until the mushroom handle grows to about 8 cm and then straighten the tube bag once again to ensure the proper temperature, humidity and carbon dioxide concentration in the mushrooming process. In this process, the mushroom body should be prevented from being forced to bend and grow.
Replacing any mushroom stalks into red light induces a strong phototaxis of the velutine mushroom, so after a good bacterium is put on the shelf, a 15 watt red light bulb can be hoisted every 4 meters above the center of the two rows to produce vertical light. Inducing its bundles toward the direction of the light source, to promote the extension of the mushroom body. However, the doors and windows should be shaded at this time to prevent the mushroom body from being disordered, lodging and bending.
Change the mushroom period to add nutrients for scientific application Many farmers know that mushroom growth regulators and other nutrients can promote mushroom growth, but often because of the law and the effect is not obvious, and even inhibit growth. It has been proved that the spraying rate of 0.5% triacontanol and 10 ml of gibberellin per kilogram of water during the fruiting period can increase the yield by more than 17%, but special attention should be paid to the concentration.
