Produce plant mushrooms
Mushroom hunters forge through damp wooded areas searching for the prized edible mushroom. They must be skilled in the identification process, because some mushrooms are deadly. There are over 3, species of mushroom throughout the world. It is a fungus, and unlike other plants, has no chlorophyll to help it manufacture food. The cap of the mushroom--the part we typically eat--is actually the fruiting part of the mushroom, and is vital to its reproduction process. The cap will last only a few days, but during that time it will create millions of spores.VIDEO ON THE TOPIC: Discovery - How its made - Mushroom production

Is Oyster Mushroom Farming Really Profitable In 2020?
Mushroom farming consists of six steps, and although the divisions are somewhat arbitrary, these steps identify what is needed to form a production system. Composting 3. Spawning 4. Casing 5. Pinning 6. These steps are described in their naturally occurring sequence, emphasizing the salient features within each step. Compost provides nutrients needed for mushrooms to grow. Two types of material are generally used for mushroom compost, the most used and least expensive being wheat straw-bedded horse manure.
Synthetic compost is usually made from hay and crushed corncobs, although the term often refers to any mushroom compost where the prime ingredient is not horse manure. Both types of compost require the addition of nitrogen supplements and a conditioning agent, gypsum. The discussion of compost preparation and mushroom production begins with Phase I composting. This phase of compost preparation usually occurs outdoors although an enclosed building or a structure with a roof over it may be used.
A concrete slab, referred to as a wharf, is required for composting. In addition, a compost turner to aerate and water the ingredients, and a tractor-loader to move the ingredients to the turner is needed. In earlier days piles were turned by hand using pitchforks, which is still an alternative to mechanized equipment, but it is labor intensive and physically demanding.
Phase I composting is initiated by mixing and wetting the ingredients as they are stacked in a rectangular pile with tight sides and a loose center. Normally, the bulk ingredients are put through a compost turner. Water is sprayed onto the horse manure or synthetic compost as these materials move through the turner.
Nitrogen supplements and gypsum are spread over the top of the bulk ingredients and are thoroughly mixed by the turner. Once the pile is wetted and formed, aerobic fermentation composting commences as a result of the growth and reproduction of microorganisms, which occur naturally in the bulk ingredients.
Heat, ammonia, and carbon dioxide are released as by-products during this process. Mushroom compost develops as the chemical nature of the raw ingredients is converted by the activity of microorganisms, heat, and some heat-releasing chemical reactions. These events result in a food source most suited for the growth of the mushroom to the exclusion of other fungi and bacteria.
There must be adequate moisture, oxygen, nitrogen, and carbohydrates present throughout the process, or else the process will stop. This is why water and supplements are added periodically, and the compost pile is aerated as it moves through the turner. Gypsum is added to minimize the greasiness compost normally tends to have. Gypsum increases the flocculation of certain chemicals in the compost, and they adhere to straw or hay rather than filling the pores holes between the straws.
A side benefit of this phenomenon is that air can permeate the pile more readily, and air is essential to the composting process. The exclusion of air results in an airless anaerobic environment in which deleterious chemical compounds are formed which detract from the selectivity of mushroom compost for growing mushrooms.
Gypsum is added at the outset of composting at 40 lbs. The purpose of these supplements is to increase the nitrogen content to 1. Synthetic compost requires the addition of ammonium nitrate or urea at the outset of composting to provide the compost microflora with a readily available form of nitrogen for their growth and reproduction. Corn cobs are sometimes unavailable or available at a price considered to be excessive. Substitutes for or complements to corn cobs include shredded hardwood bark, cottonseed hulls, neutralized grape pomace, and cocoa bean hulls.
Management of a compost pile containing any one of these materials is unique in the requirements for watering and the interval between turning. The initial compost pile should be 5 to 6 feet wide, 5 to 6 feet high, and as long as necessary. The sides of the pile should be firm and dense, yet the center must remain loose throughout Phase I composting. As the straw or hay softens during composting, the materials become less rigid and compactions can easily occur.
If the materials become too compact, air cannot move through the pile and an anaerobic environment will develop. Turning provides the opportunity to water, aerate, and mix the ingredients, as well as to relocate the straw or hay from a cooler to a warmer area in the pile, outside versus inside.
Supplements are also added when the ricks are turned, but they should be added early in the composting process. Water addition is critical since too much will exclude oxygen by occupying the pore space, and too little can limit the growth of bacteria and fungi. As a general rule, water is added up to the point of leaching when the pile is formed and at the time of first turning, and thereafter either none or only a little is added for the duration of composting. On the last turning before Phase II composting, water can be applied generously so that when the compost is tightly squeezed, water drips from it.
There is a link between water, nutritive value, microbial activity, and temperature, and because it is a chain, when one condition is limiting for one factor, the whole chain will cease to function. Biologists see this phenomenon repeatedly and have termed it the Law of Limiting Factors.
Phase I composting lasts from 7 to 14 days, depending on the nature of the material at the start and its characteristics at each turn. There is a strong ammonia odor associated with composting, which is usually complemented by a sweet, moldy smell. As a by-product of the chemical changes, heat is released and the compost temperatures increase. At the end of Phase I the compost should: a have a chocolate brown color; b have soft, pliable straws, c have a moisture content of from 68 to 74 percent; and d have a strong smell of ammonia.
When the moisture, temperature, color, and odor described have been reached, Phase I composting is completed. There are two major purposes to Phase II composting. Pasteurization is necessary to kill any insects, nematodes, pest fungi, or other pests that may be present in the compost. And second, it is necessary to remove the ammonia which formed during Phase I composting. Ammonia at the end of Phase II in a concentration higher than 0.
Phase II takes place in one of three places, depending on the type of production system used. For the zoned system of growing, compost is packed into wooden trays, the trays are stacked six to eight high, and are moved into an environmentally controlled Phase II room. Thereafter, the trays are moved to special rooms, each designed to provide the optimum environment for each step of the mushroom growing process. With a bed or shelf system, the compost is placed directly in the beds, which are in the room used for all steps of the crop culture.
The most recently introduced system, the bulk system, is one in which the compost is placed in a cement-block bin with a perforated floor and no cover on top of the compost; this is a room specifically designed for Phase II composting. The compost, whether placed in beds, trays, or bulk, should be filled uniformly in depth and density or compression.
Compost density should allow for gas exchange, since ammonia and carbon dioxide will be replaced by outside air. Phase II composting can be viewed as a controlled, temperature-dependent, ecological process using air to maintain the compost in a temperature range best suited 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 define and most commercial growers tend toward one of the two systems in general use today: high temperature or low temperature. This can be accomplished by heat generated during the growth of naturally occurring microorganisms or by injecting steam into the room where the compost has been placed, or both.
This Phase II system requires approximately 10 to 14 days to complete. It is important to remember the purposes of Phase II when trying to determine the proper procedure and sequence to follow. One purpose is to remove unwanted ammonia. A second purpose of Phase II is to remove any pests present in the compost by use of a pasteurization sequence.
The nitrogen content of the compost should be 2. Also, at the end of Phase II it is desirable to have 5 to 7 lbs. It is important to have both the compost and the compost temperatures uniform during the Phase II process since it is desirable to have as homogenous a material as possible. The mushroom itself is the fruit of a plant as tomatoes are of tomato plants.
Microscopic spores form within a mushroom cap, but their small size precludes handling them like seeds. As the tomato comes from a plant with roots, stems, and leaves, the mushroom arises from thin, thread-like cells called mycelium. Fungus mycelium is the white, thread-like plant often seen on rotting wood or moldy bread.
Mycelium can be propagated vegetatively, like separating daffodil bulbs and getting more daffodil plants. Specialized facilities are required to propagate mycelium, so the mushroom mycelium does not get mixed with the mycelium of other fungi. Mycelium propagated vegetatively is known as spawn, and commercial mushroom farmers purchase spawn from any of about a dozen spawn companies.
Spawn makers start the spawn-making process by sterilizing a mixture of rye grain plus water and chalk; wheat, millet, and other small grain may be substituted for rye. Sterilized horse manure formed into blocks was used as the growth medium for spawn up to about , and this was called block or brick spawn, or manure spawn; such spawn is uncommon now.
Once sterilized grain has a bit of mycelium added to it, the grain and mycelium is shaken 3 times at 4-day intervals over a day period of active mycelial growth. Once the grain is colonized by the mycelium, the product is called spawn.
In the United States, mushroom growers have a choice of four major mushroom cultivars: a Smooth white — cap smooth, cap and stalk white; b Off-white — cap scaly with stalk and cap white; c Cream — cap smooth to scaly with stalk white and cap white to cream; and d Brown — cap smooth, cap chocolate brown with a white stalk. Within each of the four major groups, there are various isolates, so a grower may have a choice of up to eight smooth white strains. The isolates vary in flavor, texture, and cultural requirements, but they are all mushrooms.
Generally, white and off-white cultivars are used for processed foods like soups and sauces, but all isolates are good eating as fresh mushrooms. Spawn is distributed on the compost and then thoroughly mixed into the compost. For years this was done by hand, broadcasting the spawn over the surface of the compost and ruffling it in with a small rake-like tool.
In recent years, however, for the bed system, spawn is mixed into the compost by a special spawning machine which mixes the compost and spawn with tines or small finger-like devices. In a tray or batch system, spawn is mixed into the compost as it moves along a conveyer belt or while falling from a conveyor into a tray.
The spawning rate is expressed as a unit or quart per so many square feet of bed surface; 1 unit per 10 ft is desirable. The rate is sometimes expressed on the basis of spawn weight versus compost weight; a 2 percent spawning rate is desirable. Under these conditions the spawn will grow — producing a thread-like network of mycelium throughout the compost.
The mycelium grows in all directions from a spawn grain, and eventually the mycelium from the different spawn grains fuse together, making a spawned bed of compost one biological entity. The spawn appears as a white to blue-white mass throughout the compost after fusion has occurred. The time needed for spawn to colonize the compost depends on the spawning rate and its distribution, the compost moisture and temperature, and the nature or quality of the compost.
A complete spawn run usually requires 14 to 21 days.
Starting a Mushroom Farming Business in 6 Easy Steps Growing Oyster Mushrooms
Gourmet mushrooms, such as oyster and shiitake, are one of the best cash crops for small growers. Although they are traditionally grown on logs outdoors, and still are in many areas, now both can be grown indoors in bags, using straw or sawdust instead of logs. Why grow gourmet mushrooms? Two good reasons. First, by growing indoors, the temperature, humidity and light can be controlled to give the mushrooms exactly what they need, when they need it.

How to Grow Magic Mushrooms
Posted By: Matt Ogg June 5, They may be one of the more expensive and perishable items in produce departments, but with the right merchandising approach, mushrooms have enormous potential to lift sales as consumers get hooked on their diverse umami flavors and flexible range of uses. Most vegetables will have some healthy traits, but mushrooms have the advantage of providing some key nutrients consumers will lose if they give up meat.
It has been alive since the Persian king Xerxes waged war against the Ancient Greeks and weighs more than three blue whales put together. It has a voracious appetite, eating its way through huge swathes of forest. But this is no long-forgotten beast borne of Greek mythology. It is a mushroom. He is revisiting an organism living under the forest floor that he and his colleagues discovered nearly 30 years ago.
Six Steps to Mushroom Farming
Mushroom gardens are spaces to grow gourmet delights such as oyster or shiitake mushrooms: think elegant woodland dwellings with logs and woodchip beds. Fungi are the perfect solution for slightly damp, shady city gardens, or that spot under a tree where nothing grows. Instead of battling to get plants to take hold, inoculate your ground with mushrooms instead. Growing from scratch, or more accurately spores, requires care, so start with a kit and go from there. I got a recycled plastic pot oyster mushroom kit for just under a tenner from gourmetmushrooms.

How to grow oyster mushrooms at home
A mushroom farming business can be mean big profits in just a few weeks. Plus, starting your own business growing oyster mushrooms for profit is fairly easy. You can produce your own spawn using a sterile culture, or you can buy ready-to-inoculate spawn, which are carried by suppliers. Producing your own can be cheaper in the long run, but the start-up costs can be high, so chances are buying the ready-to-inoculate spawn is the way to go for you.
Biologically, forest cultivation of mushrooms involves fungal decay of an organic substrate, usually wood. It is a rotten business to be sure. For more information specific to growing Shiitake Mushrooms visit the following guides from the University of Kentucky Cooperative Extension Service:. Spawn Selection.
First of all, we should point out that Mushrooms, in general, are slightly finicky, and will not grow in all climates. It should also be noted that you can still grow Oyster Mushrooms anywhere on Earth, simply by farming them indoors, in a controlled environment. Still, I would want to roll with local lead generation for some part-time labor that yields maximum, full-time, passive income through the internet. Our lead generation coaching program was there to help me along. The guidance provided led me toward developing a team of 5 that I manage so I can be even more hands-off with my company.
Фонтейн почти во всем полагался на Стратмора и верил в его план, в том числе и в достойную сожаления, но неизбежную необходимость устранять Энсея Танкадо и в переделку Цифровой крепости, - все это было правильно.
