Planting techniques of Pleurotus ostreatus

Find a flat sunny land to build mushroom shed, and control the temperature in the shed at 26-28 degrees. Then sawdust, bran, gypsum powder, lime, potassium dihydrogen phosphate and the like are mixed together to form culture material, and the culture material is put into bags for sterilization for 6-7 hours. Finally, inoculate in the morning or evening. After successful inoculation, it will germinate within 6 days. At this time, do a good job in basic management such as moisture and temperature. After 60-70 days, it can produce mushrooms.

High-yield cultivation techniques of mushroom:

1. Mushroom shed construction, mushroom seed selection and cultivation time

In order to cultivate the mushroom, ventilation should be carried out at all times. The length of the high shelf in the flat terrain mushroom shed is 2.4 meters, and the width and height need to be 6 meters and 2.6 meters respectively. The mushroom has just been planted, and the aging is changed under long-term low temperature. The selection of good mushroom strains is the strain that can be selected and configured at a lower temperature. The average daily temperature is 26 to 28 degrees. After 60 to 70 days of mycelium growth, the fungus bag is full. After 10 to 15 days, it can have different color changes. Generally speaking, small mushrooms can be found in November.

2. Preparation of culture medium

preparing culture material, preferably sawdust, preparing culture medium by pulverizing 2kg potassium dihydrogen phosphate, 175kg bran, 18kg gypsum powder and 2kg lime, branching tung oil of apple, pear, peach tree and other broadleaf trees, adding selected preparation medium and 2kg lime powder, converting these nutrients for 3-4 times and stirring. In another aspect, the sprayable mixture of the enhanced matrix inhibits harmful bacterial fermentation.

3. Bagging sterilization

To complete within 6-7 hours, place in a plastic tank and cover the ground with bags to produce a good nutritional polyethylene film, tape it in a sterile pressure tank and burn it while maintaining the temperature of the tank at 70 ° C. Indoor inoculation needs to be transported to 100 ° C within 4-6 hours.

4. Mushroom inoculation

Sometimes, a good product is chosen and sterilized before inoculation, leaving it for 7-10 days for inoculation. In 0.5 km sterile formaldehyde gas room, 4 days open fumigation, inoculation should be carried out in the morning or evening.

5. Cultivation management

After inoculation, the mushroom will germinate in 1-6 days without ventilation. At this time, it is necessary to control the indoor temperature within the range of only 28 degrees. 7-10 Days of mushroom, to control the temperature below 26 degrees, and please ventilate, 30 minutes each time. Strong demand for growth for 11-15 days, aeration, culture at a controlled temperature of 24 degrees. Mushroom inoculation will not be less than 16-20 days, when the bacteria bag also reached 22-24 degrees, to prevent aging, to control the temperature, increase ventilation exhaust. The bacteria will cover the bacteria bag in 45 days. When the bulge is 50 ~ 60 days, it is necessary to pay attention to the discharge of water. The fruiting time is 60 ~ 70 days. It is necessary to manage the transfer fruiting period.

The above is the introduction of mushroom cultivation technology, I hope to help everyone.
