The production of edible fungi in autumn should be grasped, and the notes on the introduction of edible fungi should be made.

There are many restrictive factors in the production of edible fungi in autumn, especially in early autumn, and the success rate is often low compared with winter production. In fact, this is the main reason why the price of fresh mushrooms is high in autumn. Therefore, specially remind the majority of mushroom farmers: in this year's edible mushroom production, especially the large-scale production base, we should strictly operate, pay attention to prevention, scientific management, in order to ensure the smooth progress of production. In actual production, the following five hurdles should be mainly monitored.

Base material ratio nutrition: in general production, cottonseed husk, corncob and other straw as raw materials. However, the nutrition of all raw materials is mainly carbon, the lack of nutrients and unreasonable, can not meet the needs of the growth of edible fungi mycelium, although it can produce mushrooms, but in the management for several months, the yield of mushrooms is very small. The reason is that the lack of medium and trace elements in the base material is the main problem, which leads to weak mycelium and poor resistance, and the result must be heavy pollution and low yield. Therefore, the addition of three-dimensional nutritional essence of edible fungi to the formula can make its nutrition comprehensive and rich, the hyphae strong and exuberant, have high resistance to impurity and disease, and achieve the ideal state of mushroom production.

Mushroom shed disinfection and sterilization: nowadays, most of the bacteria or mushrooms are carried out in the greenhouse. therefore, the eliminate virus in the greenhouse should be carried out in accordance with strict and thorough principles, and do not take chances. Especially in the old mushroom shed, there are a large number of miscellaneous bacteria and pathogens lurking in the old mushroom shed, and many mushroom farmers are busy with sowing production. Coupled with the lack of prevention awareness and prevention concept, they often ignore the eliminate virus treatment of the mushroom shed, resulting in large area pollution and sometimes irreparable losses. Treatment method: repair the mushroom shed, remove the mulch and other mulch, repair or replace the greenhouse film, pour 800 times phoxim into the water, then blanket spray the silly solution, seal the mushroom shed, expose it for 2-3 days, repeat the medicine, turn on the ventilation after 2 days, spread lime powder on the ground, and then move the bacterial bag after sowing into the bacteria.

Clinker inoculation operation: the requirement of clinker inoculation is standard operation. The traditional method is to use potassium permanganate formaldehyde or aerosol for fumigation, and then carry out the inoculation operation, on the one hand, it makes the vaccinators suffer deeply from the drugs, especially formaldehyde is a carcinogen, and the residual period is longer and the residue is large. according to the relevant regulations of green food, the use of edible fungi should be prohibited. On the other hand, the stimulation of drugs, inconvenient operation in the inoculation box and high labor intensity make the staff very tired, and the operation for a long time will inevitably be lax and non-standard, so the pollution rate remains high. The author uses the edible fungus inoculation purification machine to carry on the inoculation operation, 10 minutes after turning on, it can be inoculated in the breeze sent out by the machine, which is harmless to the human body, and has good anti-impurity effect and high success rate of inoculation, which makes the inoculation operation easy and comfortable.

During the outbreak of bacteria, diseases and insect pests: although a thorough eliminate virus has been carried out in the mushroom shed, during the infection period, with the entry and exit of managers, continuous ventilation, and so on, new miscellaneous pathogens are bound to enter the shed, so the risk of pollution still exists. Therefore, prevention work should not be slackened slightly. Generally, all diseases can be used to prevent and kill bacteria, cypermethrin can be used to kill insects, the main direction is the wall, ground, vents, doors and other places, a small amount of spray can be given in the air.

Prevention during mushroom emergence: during the whole period, in addition to drug prevention, we should closely observe the trend of miscellaneous bacterial diseases, find initial pollution or disease symptoms, and deal with them immediately and thoroughly. The method is: brushing the contaminated plaque with medicine solution such as Baixian silly, or sprinkling powder directly on the contaminated place, the pathogen can be completely killed. After the drug treatment of the contaminated bacteria bag, the light ones can continue to produce mushrooms, and the serious pollution can be used as organic fertilizer after killing the miscellaneous bacteria.
