hello Sir
Cultivation of mushroom involves:
• Substrate preparation,
• Steam pasteurization/hot water treatment of substrate.
• Spawning of substrate.
• Filling of spawned substrate in trays and polythene sheet enclosures.
• Incubation of spawned substrate in trays & enclosures.
• Harvesting and storage of fruit bodies.
Processing:
• Cleaning and grading.
• Separation of mushroom for drying.
• Packing of fresh mushroom for marketing.
• Drying of mushrooms.
• Packing of dried mushrooms.
• Marketing.
The compost-loving species require a different procedure from the wood-loving mushrooms when it comes time to get the mushrooms to form.
The compost-lovers usually need to have a soil-like layer called "casing," applied to the top of the culture, once the mushroom tissue has fully colonized the compost. The soil-like layer provides a reservoir of moisture, and it creates a low-nutrient zone (compared to the compost), signaling the mushroom tissue to start forming the fruiting bodies.
The tiny mushroom buttons then begin to form in the casing layer.
casing is kept moist by lightly watering it as the mushrooms enlarge.
With wood-loving species, the procedure for getting mushrooms to form varies a bit from one species to another, but it usually involves a shift in environmental conditions such as a drop in temperature, an increase in air circulation, and/or an increase in light levels.
Try growing mushrooms from a kit and from spawn you will have a better idea whether you want to get involved in keeping agar cultures and growing your own spawn.
These procedures require somewhat more commitment and attention to detail.
Before the invention of the peroxide technique, it was generally only possible to keep agar cultures and grow spawn if you constructed a sterile work space, such as a glove box at the very least.
With peroxide, it becomes possible to perform these steps in an ordinary kitchen, and grow the cultures just about anywhere that an appropriate temperature and light level can be provided.
You still need to learn some basic "sterile technique"--simple procedures for handling cultures to keep them pure. But you won't need a sterile facility or a spotless house.
