フェーズ1の堆肥化が終了したので、 we’ll be heading towards the second and extremely important step that is “Finishing the Compost”.
そう、 here are two major reasons for Phase two or step 2 of composting. Pasteurization is necessary to kill any unwanted bacteria, 昆虫、 線虫、 害虫、 菌類、 or other headaches that may be present in the compost. And secondly, it is necessary to remove the ammonia which formed during Phase I composting. Ammonia at the end of Step 2 in a concentration higher than 0.07 per cent is often dangerous to mushroom spawn growth, so it must be eliminated;平均して、 a person can sense ammonia when the concentration reaches the threshold of 0.10 per cent.
Whether the compost is kept in beds, トレイ、 or bulk, should be spread uniformly in-depth and compression or density. Compost density should allow for the gas to move around, this would make sure that ammonia and carbon dioxide would be replaced by the outside air.
Step 2 composting can be perceived as a regulated, temperature-dependent, ecological process using air to maintain the compost in a temperature range optimal for the de-ammonifying organisms to grow and reproduce. The growth of these thermophilic (heat-loving) organisms depends on the availability of usable carbohydrates and nitrogen, some of the nitrogen in the form of ammonia.
Optimum management for Phase II is difficult to pinpoint and most growers(commercial) tend toward one of the two systems in common use today:high temperature or low temperature. Due to the jargon nature of this process, it’s quite difficult to put the variables into exact numbers.
そのために、 you need to consult online, with someone who has experience in this field and it’s better if you find that person in your vicinity.
Step 3:Spawning
Mushroom spawning is similar to the seedling stage in agriculture and means keeping the spawn (mycelium) of mushrooms that can be purchased from a laboratory at nominal prices. After laying the spawns evenly on the tray and distributing it ergonomically, cover it with a thin layer of compost and keep it moist. Cover the tray with a wet sheet of paper and sprinkle water at regular intervals. The trays can be stacked on top of each other at a spacing of 15–20 cm. Keep the walls and floors wet to maintain a humidity-filled environment and temperature at 25 ° C.
Step 4:Casing
Be a bit vigilant about this one!
The casing is a covering applied to the spawn-run compost on which the mushrooms slowly and steadily form. The constituents are, field soil clay-loam, a mixture of peat moss with ground limestone, or reclaimed weathered, spent compost that could be utilised as the casing.
The Casing doesn’t require nutrients as the casing only acts as a water reservoir and a place where the formation of rhizomorphs takes place. The Rhizomorphs look like thick strings and form when the very fine mycelium fuses.
Casing must be pasteurized to eliminate any insects and pathogens which it might be carrying. It’s also quite important that the uniformity of the layers remains intact. This allows the spawn to move into and through the casing at the same pace and, 最終的には mushroom growth happens tauta chromatically. The casing should be able to retain moisture since moisture is essential for the development of a healthy mushroom.
The crop management after casing requires that the compost temperature be kept at around 24° C for up to 5 days after casing, and the relative humidity should be high.その後、 the compost temperature should be lowered to about -16.5°C each day until small mushroom initials have formed. Throughout the period following casing, water must be applied periodically to raise the moisture level to field capacity before the mushroom pins form. Knowing when, どうやって、 and how much water to apply to casing is an “art form” which is the subtle difference that acts as a trench between experienced growers from beginners.
Step 5:Pinning
The Mushroom instigates as and when rhizomorphs have started growing in the casing. The initials are minuscule but can be seen protruding on a rhizomorph. Once an initial grow four folds in size, the structure is a pin. Pins continue to grow larger through the button stage, and ultimately a button enlarges to a mushroom. The harvestable crop appears after around three weeks or maybe a few days here and there. Pins develop when the carbon dioxide content of room air is lowered to 0.08 per cent or lower, depending on the skill set of the grower, by introducing clean and fresh air into the growing room. Outside air has a CO² content of about 0.04 %.
If the CO² is lowered too early by airing too soon, the mycelium ceases to grow through the casing and mushroom initials plunge to the surface of the casing. As such mushrooms continue to thrive, they push through the casing and are tedious at harvest time. Too little wetness can also result in mushrooms forming below the surface of the casing. Pinning affects both the potential yield and quality of a crop and is a stepping stone in the production cycle.
Step 6:Cropping
It’s the final but a step of utmost importance. The value you’ll be generating out of this business always goes hand in hand with the ingenuity you’re putting in the cropping process.
It varies from person to person and depends upon the given below factors:
Production Capacity
Ambient Conditions
投資
Cropping Pattern
These were some of the variables you have to take care of if you want good returns. This comes in naturally as you get more and more experienced in the trade.

結論：
The world mushroom industry has accelerated very rapidly in the last two decades by way of consisting of new types of mushrooms for commercial farming.しかし、 mushroom as a vegetable has not located an ordinary area amongst Indian consumers. Despite a favourable agro-climate, an abundance of agricultural wastes, noticeably low-cost labour and wealthy fungal biodiversity, India has seen a lukewarm response in its growth.現在、 the whole mushroom manufacturing industry in India is around 0.13 million tonnes.
From 2010-2017, the mushroom industry in India has recorded a common increase charge of 4.3% per year. Of the total mushrooms produced, white button mushroom bills for 73%, observed through oyster mushroom (16%), paddy straw mushroom (7%) and milky mushroom (3%). Compared to other vegetables; The per capita consumption of mushrooms in India is low and information shows that it is much less than 100 grams per year.
In the 12 months 2016-2017, the Indian mushroom enterprise generated an income of Rs. 7282.26 lakhs by exporting 1054 quintals of white button mushroom in canned and frozen form. Considering the production figures, the demand for spawn in India is estimated to be around 8000-10000 tonnes per year. The majority of this business spawn is furnished to non-public producers and the contribution of public region corporations in spawn grants used to be constrained to only 10%.記事上で、 we attempted to analyse the contemporary state of affairs of the mushroom industry with the assistance of AICRP community centres placed throughout the US and discuss the possibilities and challenges for the improvement of mushroom entrepreneurship in India.
