The low temperature season is the main mushrooming season for edible fungi. However, there are some problems in the production of edible fungi during the annual freezing season. The main problems of this year are in four aspects:
First, the young mushrooms do not differentiate, the slow speed
In the late stage, the mushroom buds are difficult to differentiate: According to the situation, the author believes that the main problems have two aspects: First, the shed temperature is low, which is not suitable for the development and differentiation of young buds. By improving the temperature of the shed, it can be solved. Second, the effects of drugs, such as some mushroom farmers use a large number of pesticide mixes, spraying pesticides during the period of bacteria to prevent disease, resulting in heavy gas in the bag, even for mycelium inhibition.
Treatment method: After the surface is destroyed, spray 6% lime aqueous solution twice a day for 2 to 3 days, and keep the bacteria in a static state. When the bud is re-emerged, it can be managed normally; if the concentration of the drug used is high, then It needs to be solved by immersing the bacteria bag in lime water.
Young mushrooms are slow in speed: mainly because the temperature of the shed is too low, or the selected strain is not suitable for the current temperature. The treatment method is to increase the temperature of the shed. There are three main ways: First, the installation of greenhouse water temperature air conditioner, the temperature can be adjusted at will, even if the medium and high temperature strains are selected, the mushroom can be normally produced. Second, the installation of soil heating, the point is that the chimney must be smooth and keep A sufficient amount of air intake to avoid insufficient oxygen in the shed; third, drying the shed. The black plastic film or high-density sunshade net is pulled on the top of the shed, and the roll is drafted. The heat in the shed does not enter the light. The effect is good, but the rain and snow weather cannot be warmed up. The cultivation households with low-pressure furnace can put "Xiaobailong" in the shed against the wall and finally receive it on the boiler. The steam after the boiling is continuously delivered to the plastic tube, and the mushroom shed is heated. The effect is very good. it is good. If it is a medium-high temperature strain, and it is unable to heat up, it can be cooled and dehumidified, and the mushroom will be produced when the temperature rises.
Second, the mushroom cover burr, cauliflower stalk, crude stalk, mushroom cover upturned trumpet and other malformed mushrooms
The burr of the cap is the bactericidal tissue of the cockroach on the cap, which affects the quality of the mushroom. The main reason is that the shed temperature is low, or the strain is not a real low temperature type, such as the real low temperature strain 2006, even if it is below 0 °C. Malformed mushrooms such as burrs occur. The treatment method is temperature increase and heat preservation.
Cauliflower stalks and crude stalks, the former is the mushroom buds are not differentiated, the latter is the non-differentiation of the cap tissue, mainly due to the high concentration of carbon dioxide in the shed and insufficient oxygen supply. The treatment method is to enhance ventilation.
The cap is upturned, and the main cause is drug action, poor ventilation, strain degradation or the temperature of the strain does not match the conditions of the period. Treatment method: If there is chemical medicine in the base material, please refer to the treatment method of “undifferentiated young mushroomâ€; when the ventilation is poor, it should be ventilated at noon time in fine weather; the species degradation can not be cured, and the strain temperature is not Suitable for this season, it can be solved by increasing the temperature of the shed.
Third, aerial hyphae are very strong, thick fungus, no mushroom
The main reason for the aerial hyphae is that the carbon-nitrogen ratio is imbalanced and the nitrogen element is too much. The treatment method is: spraying the lime water with a concentration of about 5% on the material surface, or soaking the bacteria bag with lime water to decompose the nitrogen element as soon as possible. To achieve the level of assimilation, and at the same time strengthen or strengthen the ventilation, so that the aerial hyphae fall down and bud as soon as possible; in the future production, attention should be paid to the nutrition of the base material to make it comprehensive and balanced, especially the three-dimensional essence should be added to avoid this kind. The phenomenon occurs.
Thick fungus, the basic reason is the same as above, but it takes longer.
No mushroom, the main reason is that in addition to the imbalance of nutrients in the base material and the imbalance of carbon to nitrogen ratio, the temperature of the strain does not meet the current temperature and other reasons. In addition, the base material contains unknown substances, especially pesticides, and hyphae. Suppression occurs, resulting in no mushrooms. Treatment method: Refer to the above treatment with lime aqueous solution.
Fourth, the base of the fruit body has "pili", the mushroom products are not good, the quality of the goods is low.
The base has "pili", which is white hyphae. Some are due to poor ventilation, high humidity, aerial hyphae grown by edible fungi, and some are fungal infections. The early stage is mycelial, once the temperature rises. It will develop into a disease, such as brown rot, which is the performance of this kind. Treatment method: After cleaning the surface, spray about 400 times of silly solution, reduce the humidity, and observe that it will not develop after a week or so, then it can be transferred to normal management.
