The cultivation of oyster mushroom is usually carried out in transparent polythene covers. The size of the cover should be 60 x 30 cm, with a thickness of 80 gauge.
Procedure
-
Wash hands thoroughly with antiseptic lotion.
-
Take the polythene cover and tie the bottom end with a thread and turn it inwards.
-
Shade dry steam sterilized straw to get a uniform moisture level in all areas.
-
Take out a well-grown bed spawn, squeeze thoroughly and divide into two halves. (Two beds are prepared from the single spawn bag)
-
Fill the straw to a height of 3” in the bottom of polythene bag, take a handful of spawn and sprinkle over the straw layer , concentrating more on the edges.
-
Fill the second layer of the straw to a height of 5” and spawn it as above.
-
Repeat this process to get five straw layers with spawns.
-
Gently press the bed and tie it tightly with a thread.
-
Put 6 ventilation holes randomly for ventilation as well as to remove excess moisture present inside the bed.
-
Arrange the beds in side the thatched shed, (Spawn running room) following Rack system or hanging rope system.
-
Maintain the temperature of 22-25° C and relative humidity of 85-90 % inside the shed.
-
Observe the beds daily for contamination, if any. The contaminated beds should be removed and destroyed.
-
Similarly, observe regularly for the infestation of insect pests viz., flies, beetles, mites etc., If noticed, the pesticide like Malathion should be sprayed in side the shed @ 1 ml per litre of water.
-
The fully spawn run beds can be shifted to cropping room for initiation of buttons.
