Problems solved by technology

However, due to the continuous expansion of the production scale of shiitake mushrooms, the problem of "bacteria forest contradiction" has become increasingly prominent, lack of development and application of new compost resources, and the shortage of mushroom materials (broad-leaved tree chips) has become the main bottleneck restricting the sustainable development of the industry

preparation example Construction

[0024] A preparation method of functional shiitake mushroom cultivation substrate of the present invention, comprising the following steps:

[0025] Step 1. Select the imperial bamboo grass harvested 3 times a year, and use a sieve with a sieve hole of 5-6 mm to crush; select fresh eucommia or astragalus dregs; select fresh distiller's grains of liquor, and dry them for later use. Other raw materials are required to be fresh, dry and free from mildew.

[0026] Step 2. Weigh the above-mentioned raw materials according to the formula ratio, and dry mix them evenly. Add water and stir until the water content is 55-60%.

[0027] Step 3. After the preparation of raw materials is completed, 1.75-2.25 kg of polyethylene or polypropylene tube bags with a specification of 15-17 cm x 55 cm and a thickness of 5.5 filaments are used.

[0028] Step 4. Atmospheric pressure sterilization requires high heat to heat up for 6 to 8 hours, let the temperature in the steamer rise to 100°C, keep ...

Embodiment 1

[0033] The functional cultivation substrate of shiitake mushrooms, the ratio of each component is as follows:

[0034] 30% royal bamboo grass powder, 30% broad-leaved wood chips, 20% wheat bran, 6.5% astragalus dregs, 6.5% eucommia dregs, 5% distiller's grains, 1% brown sugar, 1% gypsum powder.

[0035] Preparation method, the steps are as follows:

[0036]The pretreatment of Huangzhucao is composting and fermenting with fermentation bacteria after being crushed, and then dried for later use; the pretreatment of astragalus and Eucommia dregs is composting and fermentation with the addition of fermentation bacteria, and drying for later use; 3% quicklime and mix well for later use. Weigh each raw material according to the above formula ratio, dry mix and mix. Add water and stir in two stages to make the water content of the matrix reach 55-60%. Use polyethylene or polypropylene tube bags with a size of 15-17 cm x 55 cm and a thickness of 5.5 silk to fill 1.75-2.25 kg. Keep t...

Embodiment 2

[0040] The functional cultivation substrate of shiitake mushrooms, the ratio of each component is as follows:

[0041] 25% royal bamboo powder, 33% broad-leaved wood chips, 20% wheat bran, 15% astragalus dregs, 5% distiller's grains, 1% brown sugar, 1% gypsum powder.

[0042] Preparation method, the steps are the same as in Example 1.

[0043] The test results show that, compared with the conventional mushroom cultivation substrate formula, the cost of raw materials is reduced by 10-30%, the production cycle is shortened by 10-20%, and the content of active substances such as lentinan and amino acids is increased by 8-20%.

[0044] Conventional formula: 78% broad-leaved wood chips, 20% wheat bran, 1% sugar, and 1% gypsum powder.

Abstract

The invention discloses a functional lentinula edodes culture medium and a preparation method thereof, and belongs to the technical field of edible mushroom cultivation. Leftover wastes such as pennisetum hydridum, traditional Chinese medicine residues and Baijiu vinasse are pretreated to replace part of broad-leaved tree sawdust serving as a conventional main material to serve as the lentinula edodes culture medium, and then the functional lentinula edodes culture medium is prepared according to the carbon-nitrogen ratio and nutritional requirements required by lentinula edodes growth. A proper formula is screened out, and the functional lentinula edodes culture medium and the preparation method thereof are provided. The method can reduce the use amount of sawdust of conventional broad-leaved trees, reduce the cost of lentinula edodes raw materials, realize resource utilization of production and processing wastes, change wastes into valuables and protect the ecological environment. Moreover, the production period of the slentinula edodes can be shortened, the harvesting frequency and labor cost are reduced, and the method is suitable for an industrial cultivation mode. The content of effective components such as lentinan and the like in the produced lentinula edodes sporocarp is improved, and therefore, the method has good development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of edible mushroom cultivation, and in particular relates to a functional mushroom cultivation substrate and a preparation method thereof. Background technique [0002] mushroom[ Lentinula edodes (Berk. ) Pegler], also known as mushroom, shiitake, flower mushroom, etc., belongs to the fungi kingdom Basidiomycota, Agaricomycetes, Agaricales, Omphalotaceae, micro Shiitake ( Lentinula ). Lentinus edodes is the second largest production of mushrooms in the world. Its artificial cultivation originated in my country. The first "log chopping method" has a history of more than 800 years. Lentinus edodes is known as the "king of mountain delicacies". As a traditional delicacy in my country, it is not only delicious and nutritious, but also has health care functions; as a generally recognized fungus for both food and medicine, its medicinal value has been written since ancient times. Records can be found in "Comp...
