Problems solved by technology

But this has brought many problems: increasing the organic nitrogen source often leads to the pollution of a large number of miscellaneous bacteria, especially the green wood fungus, which reduces production or even fails, especially when the average temperature is above 15°C. In view of this, people try to use straw, Wheat straw is crushed, wheat bran and rice bran are added, put into plastic bags and sterilized under normal pressure. This is the so-called "clinker cultivation". This method is time-consuming, labor-intensive, energy-consuming, high in cost, low in benefit, and low in practical value; The biggest disadvantage of increasing inorganic nitrogen sources is that nitrogen fertilizers are decomposed by microorganisms after being mixed with water and mixed with compost, resulting in a large amount of free ammonia, which can directly kill (burn) bacteria (mycelium) and lead to failure
The main problems to be solved at this stage are: 1. Control the growth temperature to prevent burning mushrooms
According to its method, rice straw and wheat straw are used as raw materials to cultivate oyster mushrooms, but the effect disclosed in the specification cannot be obtained.
[0022] 2. The cost and process of the two are slightly insufficient: the method disclosed in 91108444.4 requires the design and manufacture of grid tubes and hollow tubes, and the method disclosed in 92106439.X has cumbersome procedures
[0023] 3. Both of them and the previous various cultivation methods have encountered the following problems: that is, after the first tide mushrooms are harvested, the compost becomes loose and weak, resulting in thin and weak mushrooms at low tide, and some even lose their commodity value

Embodiment 1

[0059] 1. Preparation of culture medium:

[0060] Select 100kg of dry, mildew-free rice straw, soak the whole bundle in 3.8% lime aqueous solution for 3 days, pick up and drain until the water content is about 70%, and build a pile for fermentation. On the third day, the pile temperature rose to 72°C, turned over to cool down, and kept the temperature at 60-65°C. After 6 days, there were a large number of white actinomycetes in the center of the pile, which spread out to cool down.

[0061] Two, the preparation of multi-micron wheat strains:

[0062] Prepare P·D·A culture medium with non-mildewed rice straw or 230g of wheat straw and 100g of bran 100g boiled sap in a conventional method to cultivate Pleurotus ostreatus variety 1012 bacterial strain, obtain female species, use 98% of wheat and 2% of broad-leaved wood chips The compost is used to make the original seed, and then the same compost is used to make the cultivar from the original seed.

Embodiment 2

[0069] 1. Preparation of culture medium:

[0070] Select 250 kg of dry, mildew-free rice straw, soak the whole bundle in 2.5% lime aqueous solution for 3 days, pick up and drain until the water content is about 70%, and build a heap for fermentation. On the third day, the pile temperature rose to 70°C, turned over to cool down, and kept the temperature at 60-65°C. After 6 days, there were a large number of white actinomycetes in the center of the pile, which spread out to cool down.

[0071] Two, the preparation of multi-micron wheat strains:

[0072] Prepare P·D·A medium by conventional method with non-mildew rice straw or 150g of wheat straw and bran 100g boiled sap to cultivate Pleurotus ostreatus cultivar Daewoo No. % of the compost to make the original seed, and then use the same compost to make the cultivar from the original seed.

[0079] 1. Preparation of culture medium:

[0080] Select 500kg of dry, mildew-free rice straw, soak the whole bundle in 3.1% lime aqueous solution for 3 days, pick up and drain until the water content is about 70%, and build a pile for fermentation. On the third day, the pile temperature rose to 70°C, turned over to cool down, and kept the temperature at 60-65°C. After 6 days, there were a large number of white actinomycetes in the center of the pile, which spread out to cool down.

[0081] Two, the preparation of multi-micron wheat strains:

Abstract

Agaricus tabularis cultivation includes the steps of cultivation medium preparation, seed preparation, inoculation, mushroom growth, picking, etc. During seed preparation, mushroom seed with rich nitrogen content is prepared and this eliminates the problem of replenishing nitrogen and prevents hybrid mushroom pollution effectively. The wood-imitating stereo cultivation process has no mushroom burning trouble, low cost and high yield. Contracting the rice or wheat bundle as culture medium after each picking makes it possible to produce agaricus tabularis continuously.

Description

(1) Technical field [0001] The invention belongs to a cultivation method of edible fungi. More specifically, it relates to a method for cultivating oyster mushrooms with rice straw and wheat straw. (2) Background technology [0002] In the prior art, the method for cultivating Pleurotus ostreatus is a lot, as Chinese patent 90108346.1 (CN1060573A), 92106589.2 (CN1080463A), 91108444.4 (CN1061318A), 92106439.X (CN1076328A) etc., all comprise the preparation of medium, seed production and inoculation, In the steps of growing bacteria, fruiting, harvesting and management in separate stubble, cottonseed hulls with high cost are mostly used as compost. Rice straw and wheat straw have the advantages of extensive resources and low cost, but they have encountered many problems in the cultivation of Pleurotus ostreatus as the main raw material. It is mainly reflected in: when adjusting the carbon-nitrogen ratio, the side effects are large and easy to fail, the labor intensity in the...
