Description

  The present invention is a method for producing a kind of agaricus culture medium, and in particular, a simple medium (commonly known as a large empty package) produced with this culture medium is a fruiting body of agaricus.

  Agaricus has become a universally accepted health food since it was imported from abroad and commercialized. Currently, commercially available Agaricus is mostly a mycelium product, not an Agaricus fruiting product. This is because the growth of Agaricus fruiting bodies is related to factors such as culture medium and culture technology, and the key to success in controlling the amount and quality of artificially grown Agaricus is how to supply the appropriate amount of nutrients. is there.

  Currently, there are three types of culture media that are universally used to produce mushrooms: grain culture media and straw culture media. Among them, the grain culture medium is suitable only for the culture medium for simple medium seeds, which is expensive and not practical for agaricus cultivation. Since the koji culture medium is suitable only for mushroom culture medium, this culture medium usually contains heavy metals, and has high fiber content and is difficult to decompose, so it is not suitable for healthy agaric cultivation. The large sawdust culture medium is now used as an agaricus culture medium, but since the large sawdust is not treated, the fibers and woody elements in the medium are not completely decomposed, and various bacteria are prone to grow. So the culture medium can harvest only 25 to 30 grams of dry agaricus with roughly 1 kilogram of large sawdust.

  The object of the present invention is to provide a method for producing and preparing a kind of agaricus culture medium. This method becomes an agaricus culture medium provided with nutrients for cultivating agaricus by carrying out the compost fermentation process twice, and a good yield is obtained.

  Another object of the present invention is to provide a culture medium that has undergone a special compost fermentation process, so that the culture medium can be used for cultivation of agaric fruit bodies and aim for a good yield.

  The first object of the present invention is a method for producing an agaricus culture medium, the steps of which are described as follows. Large sawdust is deposited at a height of 5 to 15 meters, and the first fermentation and rot are performed for about three months. The dried sterilized cow dung is put into the large sawdust fermented in the first time, and the second fermentation is performed. The large sawdust fertilizer is 5 to 15 meters high and the temperature inside the fermentation is increased from 70 to 90 degrees. The first and second fermentations described above need to be turned upside down periodically every 15 to 30 days, and after turning over, the large sawdust pile is poured to the extent that it overflows. Finally, if the fermented sawdust has a dark coffee brown color close to black and there is no ammonia smell of ammonia, the treatment of the culture medium is complete.

  The second object of the present invention is that the Agaricus culture medium contains 75% large sawdust treated with compost fermentation and 25% cattle dung treated with sterilization.

  The characteristics of the above-mentioned first and second purpose agaric cultures are as follows. The cow dung in the ingredients contains fiber, minerals, vitamins, etc., and is easy to be absorbed by Agaricus and easy to grow, so you can increase the yield of Agaricus. In addition, since the culture medium after the second fermentation treatment reduces harmful components therein, it is possible to grow agaricus that is not harmful to human health. In order to provide the above-mentioned features, comparing the Agaricus culture medium of the present invention with the technology in the same field, it provides not only the growth of Agaricus fruiting bodies, but also the yield is high, and the product has a rich texture and a light texture. It has a taste and does not contain harmful ingredients.

d. Turn over large sawdust periodically.
e. The fermented large sawdust has a dark coffee brown color close to black, and if there is no ammonia smell of ammonia, it is completed by a kind of agaricus culture medium production method.
The invention of claim 2 is characterized in that, in the method according to claim 1, when the large sawdust is fermented first and second times, it is periodically turned over every 15 to 30 days. This is a method for producing agaricus culture medium.
The invention according to claim 3 is the method according to claim 2, wherein the sawdust is periodically turned over and then poured into the sawdust stack until it overflows. The manufacturing method.
The invention according to claim 4 is characterized in that, in the method according to claim 1, the ratio of large sawdust and cow dung when the large sawdust is second-fermented is 75% large saw and 25% cow dung, This is a method for producing agaricus culture medium.
The invention according to claim 5 is the method according to claim 1, wherein when the sawdust is subjected to the second fermentation, lime powder or calcium carbonate is added and ph is adjusted. It is a manufacturing method.
The invention according to claim 6 is the method according to claim 1, wherein cow dung is sterilized at a temperature of 60 to 75 ° C.
The invention of claim 7 is a kind of agaricus culture medium, comprising 75% of large sawdust after two fermentation treatments and 25% of sterilized cow dung, which is a method for producing agaricus culture medium.

  The characteristics of Agaricus culture medium are as follows. The cow dung in the ingredients contains fiber, minerals, vitamins, etc., and is easy to be absorbed by Agaricus and easy to grow, so you can increase the yield of Agaricus. In addition, since the culture medium after the second fermentation treatment reduces harmful components therein, it is possible to grow agaricus that is not harmful to human health. In order to provide the above-mentioned features, comparing the Agaricus culture medium of the present invention with the technology in the same field, it provides not only the growth of Agaricus fruiting bodies, but also the yield is high, and the product has a rich texture and a light texture. It has a taste and does not contain harmful ingredients.

  A method for producing a kind of good agaricus culture medium provided by the present invention, and its steps are described as follows. Large sawdust is deposited at a height of 5 to 15 meters, and the first fermentation and rot are performed for about three months. Periodically turn over the large sawdust. The dried sterilized cow dung is put into the large sawdust fermented in the first time, and the second fermentation is performed. The large sawdust fertilizer is 5 to 15 meters high and the temperature inside the fermentation is increased to 70 to 90 degrees. Periodically turn over the large sawdust. If the fermented sawdust color is dark coffee brown close to black and there is no ammonia smell of ammonia, the production of this culture medium is completed.

  During the second fermentation of the Agaricus culture medium production step described above, 60-75 ° C. cow dung that has been dry-sterilized must be placed in the sawdust. At the same time, lime powder or calcium carbonate is added at an appropriate time to adjust the pH of the compost. The reason for controlling the internal temperature from 70 to 90 degrees during the second fermentation is to completely ferment the sawdust. In addition, it is avoided that other germs remain in the culture medium due to the action of sterilization at a high temperature of fermentation, which affects the growth of Agaricus.

  The reason why the sawdust is periodically turned over every 30 days during the first and second fermentations during the production step of the agaricus culture medium described above is to sufficiently ferment the sawdust sufficiently on average. Each time you turn it over, pour water into the new large sawdust. The best way to do this is to put the hose into a large sawdust and the water will overflow.

The key points for completing the production of this culture medium after the second fermentation is carried out in the above-mentioned steps of manufacturing the agaricus culture medium:
1. The color of the large sawdust that has not yet been fermented is a shallow coffee color (during the first fermentation), and the second sawdust when it is rotted, the large sawdust color changes from a shallow coffee color to a dark coffee brown, Or if it becomes a color close to black, it will be evidence that the fermentation is complete.
2. The smell of large sawdust Before the large sawdust is completely fermented, it smells like urine, but when the smell of ammonia disappears during the second fermentation, it means complete fermentation.

  Of the above-mentioned steps for producing Agaricus culture medium, it is considered that the pyramid type is preferable for the accumulation of sawdust during the first or second fermentation.

  The components of Agaricus culture medium produced and prepared by the method described above are 75% large sawdust and 25% cow dung. Among them, since the large sawdust is fermented twice, the large sawdust fiber and wood element in the component are almost decomposed and easily absorbed effectively by Agaricus. In addition, through two fermentations, the harmful components such as phenol, chlorophenol and organic acids are reduced to a minimum. Avoid transferring those harmful ingredients to Agaricus and not harming the health of the user. In addition, the culture medium of the present invention contains a cow dung component. Cow dung contains a high amount of grass fiber, minerals and vitamins, and the grass fiber in it is easily absorbed by species of grass fungi such as Agaricus, while minerals and vitamins grow when Agaricus grows. Provides the necessary ingredients. Therefore, the yield using the culture medium of the present invention can produce 35 to 40 grams of dried Agaricus fruit bodies that are fermented twice per kilogram. The amount is higher than other cultivation techniques.

What has been described above fully describes the feasibility and results of implementing the present invention with various implementation methods. However, it is only a good embodiment of the present invention and cannot be regarded as a limiting condition of the present invention. The specific scope of rights of the present invention will be described in the scope of patent application of the present invention.
