Three ways to deal with edible mushroom raw materials

Cultivation of edible fungi, raw materials are raw materials, fermentation materials, clinker three treatment methods. From the raw material to the fermentation material and then to the clinker, the maturity of the culture material is from shallow to deep, the decomposition degree of the nutrient component is from light to heavy, and the number of the heterotrophic bacteria is from more to less, but the degree of invasion by external bacteria is From difficult to easy, from the operating point of view is from simple to cumbersome, from the production point of view is from low to high, the producer should be based on their own circumstances, a reasonable choice.

Raw material cultivation Raw material cultivation refers to the cultivation method of directly bagging inoculation without any treatment after the blending is completed. As the name suggests, the culture material is raw material that has not been cooked or sterilized. This cultivation method is simple, time-saving and labor-saving, but the slow bacterial growth after inoculation, the inoculum size should be large, and in the germination process will cause post-fermentation, resulting in high-temperature burning bacteria. In hot summer, high temperature and rain, if the cultivation method is improper, it is easy to cause acidification and rot in the raw material and the cultivation fails. Therefore, raw material cultivation is limited to oyster mushrooms, straw mushrooms, etc., which have strong mycelium growth ability.

Fermentation cultivation Fermentation cultivation is to mix the raw materials, build a pile according to certain specifications, and enter the fermentation process. When the pile temperature reaches a certain level, it is necessary to turn it over and it will generally be turned 3 to 5 times. Through the fermentation process, harmful microorganisms and pests in the culture can be killed, but the operation is troublesome and the cost is high. Pleurotus ostreatus, straw mushroom, Agaricus bisporus, Coprinus comatus, etc. are all suitable for the cultivation of fermentation materials.

Cultivated clinker cultivation means that the culture material after bagging (bottle) is sterilized under normal pressure or autoclave. On the one hand, it is conducive to the decomposition and utilization of mycelium, and on the other hand it can kill harmful microorganisms in the culture material and Pests. This cultivation method is suitable for the cultivation of the vast majority of edible fungi, but it requires a lot of investment to purchase sterilization equipment and inoculation equipment, and it requires high cultivation technology. Cultivating clinker is more time-saving than fermented material, and it is more active in terms of time. It is convenient for mass production according to manpower and material resources, and the amount of inoculum can be greatly reduced. Mushrooms, king oyster mushrooms, enoki mushrooms, fungus, white fungus must be cultivated.
