Mushrooms: After the mushroom primordia occurs, the rate of cap differentiation and development is not normal. It is characterized by small caps, long stipe, and thick shank hard and low commodity value. The main reason for this was the use of stifling heat insulation and cold protection measures, resulting in insufficient oxygen supply and loss of nutrient transport in mushrooms. Preventive measures: In case of continuous low-temperature weather, the mushroom sheds used to take suffocating heat insulation should be ventilated for a short period of time at noon. However, they should not be blown by strong winds to prevent the death of young mushrooms.
Blue mushroom: When the mushroom body grows, the blue halo of the edge of the cap is produced. In severe cases, the entire mushroom is even splashed with blue ink until the mushroom body is not faded. Cause: Take firewood, coal fire and other means to increase the temperature, so that the mushroom shed poisonous gas carbon monoxide increased, causing mushroom poisoning, stimulating the mushroom body color change reaction. Preventive measures: The temperature of the mushroom shed in winter is better with daylight, heating, electric heating, etc. If firewood and coal fire are used for heating, closed heat-transfer and flue gas exhaust pipes must be installed.
Mushrooms Mushrooms: During the development of the mushroom body, the growth is slow, and knobs or granular protrusions appear on the surface of the cap. When the victim suffers serious damage, the cap is stiffened, and the mushroom hardens and stops growing. The reason is that the temperature during the development of the mushroom body is too low and the duration of the low temperature is too long, which causes the elongation of the inner and outer cells of the cap. Preventive measures: It is necessary to clarify the minimum temperature for the normal development of cultivated varieties of mushroom body tolerated, winter cultivation should choose low-temperature varieties, while strengthening the insulation temperature measures to control the mushroom shed (room) mushrooming temperature. Usually the medium temperature mushroom sheds should be controlled above 8°C, and the low temperature cultivars should be controlled above 0°C.
