The low temperature in winter and the few bacteria in the air are good seasons for the cultivation of oyster mushrooms. However, the following kinds of malformed mushrooms are prone to appear in the mushrooms:
After the occurrence of the primordium of Pleurotus eryngii, the rate of cap differentiation and development was not normal. It showed that the cap was small, the length of the stalk was long, and the stalk was coarse and hard, and the commodity value was low. The main reason for this was the use of stifling heat insulation and cold protection measures, which resulted in insufficient oxygen supply to the mushroom shed (room) and the loss of nutrient transport in the mushroom body. Preventive measures are: In the case of continuous low-temperature weather, mushrooms mushroom shed (room) to take stifling heat insulation should pay attention at noon for a short period of ventilation and ventilation, but avoid direct blowing the material surface, prevent the cause of young mushrooms death.
When the blue mushroom grows, blue halos are formed on the edge of the cap, and even if the whole body is blue, it will splash blue ink until the mushroom body is no longer receded. The reason is: Take firewood, coal fire and other smoke with a warming temperature to increase the carbon monoxide poisonous gas in the mushroom shed (room), resulting in poisoning of the mushroom body, to stimulate the color change reaction of the mushroom body. Preventive measures are: The winter mushroom shed (room) warming method to take the sun, heating, electric heating and other methods as well, such as the use of firewood, coal fire heating, should be installed closed heat transfer smoke pipe.
During the development of L. edulis mushroom body, the growth was slow, and nodular or granular protrusions appeared on the surface of the mushroom cap. When the victim suffers serious damage, the cap is stiffened, and the mushroom hardens and stops growing. The reason is that the temperature of the mushroom body is too low, and the low temperature duration is too long, which causes the imbalance of cell growth in the inner and outer layers of the cap. The prevention measures are: When cultivated, the lowest temperature that can be tolerated under the premise of the normal development of cultivated mushroom body varieties must be ascertained. In the winter planting, the medium-low temperature type should be selected, and the measures for keeping the temperature and the insulation warm should be strengthened to control the mushroom shed (room). Mushroom temperature. Usually the medium temperature type mushroom shed (room) temperature should be controlled above 8°C, and low temperature type varieties should be controlled above 0°C.
