Problems solved by technology

Among them, the grain culture medium is only suitable for making the original seed medium of the space pack, such as being used for making Brazil mushrooms, which is expensive and not practical
Straw medium is only suitable as a medium for mushrooms, and it usually contains heavy metals and is high in fiber, which is not easy to decompose, so it is not suitable for growing Agaricus mushrooms for cultivation
Sawdust medium, although it is currently used as a medium for Agaricus mushrooms, because the sawdust has not been treated, the cellulose and lignin in it are not completely decomposed, and it is easy to produce miscellaneous bacteria. Therefore, this medium The harvest yield of approximately 1 kg of sawdust yields only 25 to 30 grams of dried aziz mushrooms

Embodiment Construction

[0010] Only illustrate the practicability and effect characteristics of the present invention with preferred embodiment below:

[0011] A preferred method for preparing Agaricus mushroom culture medium provided by the present invention comprises the steps of: pile up sawdust with a height of 5 to 15 meters, carry out the first fermentation and decay for about 3 months; carry out periodic sawdust turning ;Add dry and sterilized cow dung to the first fermented sawdust for the second fermentation. The height of the sawdust fermentation pile is 5 to 15 meters, and the internal temperature of the fermentation is 70 to 80 degrees; Periodic sawdust turning; observation The color of the fermented sawdust is dark brown close to black, and the preparation of the culture medium is completed without the smell of urine of ammonia.

[0012] In the preparation step of the above-mentioned Agaricus mushroom culture medium, during the second fermentation, sawdust must be added to dried and ster...

Abstract

The invention relates to a method for preparing Brazilian mushroom culture medium, comprising following steps: piling up wood dust to 5 to 15 meters for the first time fermentation for 3 months; pile turning for every 15 to 30 days; adding sterilized cattle manure into fermented wood dust for second time fermentation, the temperature inside pile reaches to 70- 80 Deg. C; pile turning for every 15- 30 days; when wood dust turns to dark coffee and space packed gets base raw material for Brazilian mushroom cultivation.

Description

technical field [0001] The invention relates to a method for preparing a medium for Agaricus argentina, in particular to a space bag prepared with the medium, which can cultivate the fruiting body of Agaricus argentina. Background technique [0002] After being introduced from abroad and commercialized, Brazil mushroom has become a generally acceptable healthy food for Chinese people. At present, most of the Agaricus Agaricus products on the market are their mycelium products rather than their fruiting body products. The reason is that the cultivation of Agaricus Agaricus fruiting bodies involves factors such as culture medium and culture technology, and the success or failure of the yield and quality control of artificially cultivated Agaricus Agaricus , is how to supplement the right amount of nutrient supply is a very important key. [0003] Currently, there are three types of culture media commonly used for the production of mushrooms: grain culture medium, straw cultur...
