1. Frequent ventilation and short ventilation: appropriately increase the number of ventilations and shorten the ventilation time, especially for bacteria sticks without water-retaining film, the ventilation time should not be too long . 2. Wide ventilation, small ventilation: open both ends and the middle of the greenhouse, but the area should not be too large, so that all spaces in the greenhouse can be ventilated in a short time, and generally no strong wind will enter the greenhouse using this method. , so it generally does not affect the mushrooms on the mushroom sticks.
1. Correct ventilation methods for mushroom greenhouses
1. Frequent ventilation and short ventilation
(1) For the ventilation work of mushroom greenhouses, you can take Use the method of frequent ventilation and short ventilation, especially for those bacteria sticks that do not use water-retaining film. The ventilation time for them should not be too long each time, but the number of ventilations per day can be appropriately increased several times.
(2) If a bacteria stick with a water-retaining film is used, the ventilation time can be appropriately extended each time.
2. Wide ventilation, small ventilation
(1) The length of the mushroom greenhouse is generally about 50 meters. If both ends of the greenhouse are opened for ventilation, oxygen exchange cannot be achieved in a short time. For the purpose of dehumidification (especially the bacteria rods in the middle), it is appropriate to adopt the method of wide ventilation and small ventilation, that is, opening both ends and the middle of the greenhouse, but the area should not be too large, so that all the space in the greenhouse can be fully ventilated in a short time. Let's all take a breath.
(2) Using this method for ventilation will generally not affect the mushrooms on the mushroom sticks because strong wind will not enter the shed.
3. Precautions
There is no fixed time and rule for ventilation of mushroom greenhouses. During the actual production process, appropriate ventilation should be carried out according to the weather at that time and the temperature and humidity in the greenhouse. Adjustment means adapting to people's conditions, to the conditions of the shed, and to the weather.
2. What kind of disinfectant should be used to disinfect the mushroom shed?
1. Clotrimazole (special type for mushrooms)
Mix 10 grams of clotrimazole with water for every 50 grams -15 kg, then spray the inner wall and bed frame of the greenhouse (requires uniformity and meticulousness), and then close it for half an hour.
2. Venus Disinfectant
Dilute Venus Disinfectant 50 times with water, then spray the solution on the shed wall, or heat and fumigate, the dosage is 30 ml/per cubic meter.
3. Formaldehyde
Place formaldehyde in an iron pot, pour 5 times the amount of water, and then heat it with a stove to vaporize and diffuse the formaldehyde, thus killing the adhesion Miscellaneous bacteria on the inner walls of greenhouses, bed frames, and mushroom houses.
4. Potassium permanganate formaldehyde
Put the formaldehyde into a basin, and then add potassium permanganate (the ratio is 5 grams of potassium permanganate, 10 grams per cubic meter of space) ml of formaldehyde), and the heat generated by their chemical reaction is used instead of the furnace fire for heating, so that gasification and disinfection can be carried out.
5. Bleaching powder
Use 0.1 bleaching powder solution to soak the mushroom bed’s panels, crossbars, and padding for 10 minutes (wash them before soaking), then take them out to dry. Dry and set aside, then spray the greenhouse wall with 0.1 bleach solution.
6. Peracetic acid
If the mushroom bed is difficult to disassemble, you can spray 0.2 peracetic acid for disinfection. After spraying, the mushroom shed should be sealed to increase the humidity in the air to improve the quality of the mushroom bed. Disinfection effect. Doors and windows need to be closed for 1-2 days before they can be opened, otherwise the disinfection effect will be affected.
