The turning of mushrooms during the summer is in the high-temperature season. During this period, due to changes in environmental conditions or improper management, some abnormal phenomena occur in the mushroom bar, affecting yield and quality. Therefore, when nodule nodule is formed and enters into color transition, it is necessary to strengthen management and generally do not move or collide the rod. The management must focus on “control of temperature, ventilation, water spray, temperature change, stimulation, and pest control. "And other technical aspects.
First, the required temperature during the temperature control during the color change is 18°C~22°C. During the production process, the temperature in the shed is preferably controlled to be below 33°C. When the temperature is too high, shading or shade nets must be added, and direct sunlight must not be applied to the bacilli.
The second is that the relative humidity of the air in the shed is 70%~80% during the conversion of the moisture management. When the color is changed, the humidity is too large, which can cause the hypha to be long and affect the output. When the humidity is too low, the fungus stick is difficult to change color. In the early stage of color conversion, ground watering can be performed in the morning and evening to increase the air humidity in the shed. After the bacteria rods turn color and enter the rainy season, the air humidity in the shed is relatively large, and the spraying of water is stopped. If the humidity exceeds 80%, lime powder may be sprinkled on the ground to dehumidify.
The third is temperature management before the mushroom color conversion period, during the daytime sheds should be covered with straw curtains, leaving vents underneath, at night can be unrolled straw and film to allow air to fully enter. In this way, the temperature difference between daytime and nighttime can reach above 10°C. For 3 to 4 days of continuous temperature difference stimulus, irregular white cracks appear on the surface of the bacteria stick and soon enter the color transformation phase.
The fourth is to stimulate the switch of dry and wet alternating stimuli, which is conducive to turning color. The more the air flows after spraying, the easier it is to change color. Therefore, when ventilating and ventilating, it is also necessary to pay attention to the combination of ventilation to spray moisture. In addition, the stimulation of light and darkness is also conducive to the color change, to increase the scattered light irradiation.
The fifth is to strengthen the ventilation production practice shows that when the temperature reaches 34 °C or more, good ventilation, the hyphae can also safely over the summer, without ventilation, the duration of 4 hours 34 °C ~ 35 °C above the high temperature, it may cause " Burning bacteria, causing the death of mycelium. At present, it is the high-temperature season for mushrooms that often occurs in the high-temperature weather of 35°C. Ventilation must be strengthened. Management requires that the curtains on both sides of the sunny shed can lift 40-50 cm high to prevent sunlight from directly hitting the fungus sticks. When cloudy, the grass curtains should be lifted to a large degree. There is no problem with the lightly-colored bacilli sticks, so plastic film can be peeled off to the upper part of the shed to increase the ventilation and cooling effect. In the event of heavy rain, the film can be put down, but the two sides of the shed must still be ventilated.
Sixth, pest control has entered the summer and is a pest-prone season. We must do a good job of environmental sanitation inside and outside greenhouses and find bugs such as mushrooms and flies. We can spray mushrooms and net insecticides on the surfaces of the sheds and greenhouses, usually once every 7 days, and even spray 2 times. ~3 times. According to the test, the effect of hanging insect traps in the greenhouse is very good. In addition, the cotton ball can be weighed in the dichlorvos solution and hung in the shed. The 48m2 shed can be used to hang three cotton balls. In order to prevent insects from entering the mushroom shed, pest control nets can be installed on the vents of greenhouses to prevent insects.
