Oyster mushroom is an edible mushroom with planting area and yield, but large-scale planting will lead to unstable yield, the main reason is improper planting time, some bags are full of mushrooms after the mushroom does not come out or after the head stubble is picked, the second stubble protobasic is delayed. The variety is not good, the management method is not scientific enough, so how to cultivate the oyster mushroom? Let's introduce the measures for the smooth emergence of mushrooms in the cultivation of oyster mushrooms.
Why don't oyster mushrooms come out?
1. Strains. Substandard strains
2. Medium PH. Ph.D. is too high, mainly due to excessive addition of white ash.
3. Formula ratio. Insect repellent or drugs have been added incorrectly or in excess in the formulation.
4. Carbon-nitrogen ratio. The low carbon-nitrogen ratio may lead to no mushrooms, too much nutrient addition, too low carbon-nitrogen ratio, and high nutrient ratios lead to hyphal nutrient growth time is too long, which is not conducive to the transition to reproductive growth.
5. Mushroom environment. Extreme environments such as too high temperature, too low temperature, and low humidity can lead to no mushrooms.
Oyster mushrooms need a larger humidity during the mushroom production period, and the humidity needs to be controlled at more than 80%, but the humidity cannot be too large, and the mushroom shed cannot be in a dripping state for a long time, otherwise it is easy to appear "yellow mushrooms". In production, it can be moisturized by filling, spraying and other ways. The ventilation of oyster mushrooms should be combined with temperature and humidity regulation, and ventilation should be carried out under the premise of ensuring a certain temperature to increase the amount of oxygen required for oyster mushrooms. Generally, when the temperature in the mushroom shed is 5 °C ~ 8 °C, a certain vent can be opened; when the temperature is 2 °C ~ 3 °C, the vents need to be closed.
In addition, the work of thinning buds is also very important. Mushroom buds with vigorous growth and rapid development are selected as cultivation objects, and some other small mushroom buds can be removed in advance to prevent excessive consumption of nutrients.
5, air stimulation: close the doors and windows or cover film, increase the concentration of carbon dioxide, and then ventilate twice a day, each time for half an hour.
6. Soil covering and pressure stimulation: press tiles or wooden boards or bricks on the mushroom bed or mushroom bag. Mushroom bed cultivation covers 1 to 1.5 cm thick soil grains, which not only prevents miscellaneous bacteria but also moisturizes and promotes mushrooms.
Finally, in the cultivation of oyster mushrooms, as long as the mushroom bag germs are normal and the temperature type of the bacteria is appropriate, the oyster mushrooms can be smoothly produced. Hope the above methods can help you, there are some good suggestions to communicate with each other.
