Hypsizygus marmoreus culture medium containing sawdust of pinaster and cedar and preparation method thereof

Abstract

The invention provides a hypsizygus marmoreus culture medium containing sawdust of pinaster and cedar. The hypsizygus marmoreus culture medium containing the sawdust of pinaster and cedar is prepared from the following raw materials in parts by weight: 35 to 57 parts of cottonseed hulls, 5 to 10 parts of bagasse, 5 to 20 parts of sawdust of pinaster or cedar, 15 to 20 parts of barley husks, 0 to 15 parts of corncobs, 4 to 5 parts of corn flour, and 2 to 3 parts of lime powder. The invention also provides a preparation method of the hypsizygus marmoreus culture medium containing the sawdust of pinaster and cedar. The preparation method comprises the steps of sequentially composting, mixing, transferring the mixed materials into a bottle, sterilizing and cooling; the composting is performed by spraying with water, stockpiling and pile-turning. The hypsizygus marmoreus output of the hypsizygus marmoreus culture medium is basically equal to or more than that of the traditional sawdust hypsizygus marmoreus culture medium; the sawdust of pinaster or cedar is used for replacing the traditional sawdust of broad-leaved trees, so that the damage to the broad-leaved tree forest can be decreased; the sawdust of pinaster is processed by the composting method, and oily aromatic hydrocarbon compounds in the sawdust of pinaster can be automatically decomposed and converted into nitrogenous fertilizer for growth of hypsizygus marmoreus during long-term stockpiling with water, and therefore, both time and force can be saved, the efficiency is high, and mass production can be carried out.

Description

technical field [0001] The invention relates to an edible fungus culture medium, in particular to a seafood mushroom culture medium containing pine and fir sawdust and a preparation method thereof. Background technique [0002] The main raw material of traditional seafood mushrooms and other edible fungus culture medium is broad-leaved wood chips (commonly known as "miscellaneous wood chips") rather than coniferous tree (pine, fir, etc.) wood chips (commonly known as "fir wood chips"). The wood of broad-leaved sawdust is relatively soft, which is helpful for the decomposition and absorption of mycelium, and is one of the main raw materials in the production of traditional edible fungi. In recent years, the rapid development of the edible fungi industry has brought considerable economic benefits to the majority of edible fungus growers, but it has also brought great troubles. Since the main production raw material of traditional edible fungus culture medium is broad-leaved t...

Problems solved by technology

[0004] During the development of edible fungi, cooking and distillation methods are also used to degrease pine and fir sawdust, and the degreasing pine and fir sawdust can be used in the production of edible fungi. The effect is not good and cannot meet the needs of large-scale production. Therefore, the utilization rate of pine and fir sawdust in my country's cultivated edible fungi is extremely low.
