Problems solved by technology

[0002] In the cultivation process of edible fungi, in order to increase the yield of edible fungi, the nitrogen content in the medium must be higher, but the higher the nitrogen content, the easier it is for bacteria to grow in the medium, which will pollute the culture material and inhibit The contradiction of the growth of edible fungi has been a problem that scientific and technological workers have been unable to solve for a long time; in order to inhibit the growth of miscellaneous bacteria, in addition to high-temperature and high-pressure sterilization of the compost, the inoculation must be carried out in an inoculation box or a sterile room. In the process, chemical drugs such as carbendazim are also added to inhibit the growth of miscellaneous bacteria, but chemical drugs also have an inhibitory effect on the growth of some edible fungi, and these chemical substances will remain in the cultivated edible fungi, which will harm the human body after eating. bad health
The nitrogen source in the culture material of the traditional cultivation method is provided by the bran containing 13% of crude protein. In order to increase the nitrogen content in the culture material, soybeans with high crude protein content (36%) are crushed and added to the culture material. But practice shows that such high-nitrogen substances can only be decomposed and utilized by edible fungus mycelium at one time, and its utilization rate is low, and the addition amount must be controlled, otherwise it will pollute the compost, so the output of edible fungi cannot be greatly increased. increase, but the production cost is high, and the product lacks market competitiveness

Embodiment 1

[0015] Embodiment 1: when cultivating Pleurotus eryngii, select bean dregs, cottonseed dregs as the material containing crude protein, be pulverized into fine particles, and expand, mix with potassium dihydrogen phosphate, magnesium sulfate, vitamin B, E after pulverizing After being uniform, it is made into granules, wherein okara accounts for 70% (percentage by weight), cottonseed dregs accounts for 27.8% (percentage by weight), potassium dihydrogen phosphate accounts for 1% (percentage by weight), and magnesium sulfate accounts for 1% (percentage by weight). Vitamin B and E account for 0.2% (percentage by weight); the above-mentioned granules are first coated with a layer of wet starch, and then coated with miscellaneous sawdust powder or rice husk powder.

Embodiment 2

[0016] Embodiment 2: because the growth of shiitake mushroom requires lower fat content, therefore select the bean dregs with extremely low fat content as the material containing crude protein, it is pulverized into fine particles, and expanded, and potassium dihydrogen phosphate after pulverizing, After vitamin B1 is evenly mixed, it is made into granules, wherein bean dregs account for 91% (percentage by weight), potassium dihydrogen phosphate accounts for 7% (percentage by weight), and vitamin B1 accounts for 2% (percentage by weight); above-mentioned granules are first wrapped with a A layer of wet starch, and then wrapped in miscellaneous sawdust powder or rice husk powder.

[0017] When in use, the prepared nutrient additive granules are mixed with conventional culture materials in a certain proportion and can be used as culture materials for edible fungus cultivars.

Abstract

A granular nutritive additive for culturing edible fungus is composed of core containing crude protein and the water-insoluble coated layer which can be decomposed into carbonhydrate by the mycelia of edible fungus. It can be added to the culture medium of edible fungus to greatly increase the yield of edible fungus.
