In the autumn, the production of a variety of mushrooms has come to an end, and the disinfection of the greenhouse has become the primary task of the current mushroom farmers. How to improve the disinfection and sterilization effect of mushroom shed disinfection?
Disinfection in the shed. All the edible fungus production waste bags in the shed will be removed from the shed and cleaned. Because the waste after the production of edible fungi is easy to breed bacteria, the amount of pathogenic spores in the shed is increased, so it must be thoroughly removed.
Disinfection of the medicament. When sterilizing the mushroom shed with a chemical, the mushroom farmer can select fumigant sterilization such as sulfur, formaldehyde-potassium permanganate or sodium dichloroisocyanurate. Among the three, the sulfur dioxide produced by the combustion of sulfur can play the dual role of sterilization and insecticide, but the sulfur dioxide generated during use is also easy to react with the water vapor in the air to form sulfurous acid, corroding the steel wire in the mushroom shed. Wait. When using formaldehyde-potassium permanganate disinfection, it is necessary to pay attention to the water pouring agent after pouring the powder, that is, first pour the potassium permanganate into the container, then pour the formaldehyde on the potassium permanganate, do not use it upside down. In the order, formaldehyde reacts strongly with potassium permanganate to prevent the liquid from splashing onto the body. The method of using sodium dichloroisocyanurate is the simplest, as long as the amount of 3 grams per cubic meter of space is used, 15-25 points per 667 square meters are set in the shed, and the agent can be ignited. Of course, the mushroom farmers who have the conditions should first remove the film on the upper part of the mushroom shed, use the ultraviolet rays in the sunlight to sterilize, and then use the agent to disinfect before the edible fungus is planted.
Ventilation and exhaust. When the mushroom shed is sterilized and disinfected, the mushroom farmers should pay attention to timely ventilation, and discharge the toxic gas in the shed outside the shed to prevent the toxic gas from affecting the growth of edible fungi during the production of edible fungi.

The level of IgM antibody begins to rise after 1 week after the initial infection, while the IgG appears later than IgM (usually in 14 days after infection) and can last for 6 months or even several years, which meansthat the IgG serves as an indicator of previous infection. Suspected patients that are infected by 2019-nCoV can be rapidly identified by simultaneous monitoring of IgM and IgG. During the outbreak period of2003-SARS and the 2016-Zika, IgM / IgG antibody detection was used as one of the recommendeddiagnostic methods.
