Problems solved by technology
[0002] At present, in the production of edible fungi, especially the production of wood-rot fungi, because fresh wood chips are impure or contain a large amount of substances that inhibit mycelium growth, and the structure of wood chips is tight, it is not easy to be decomposed and utilized by edible fungus mycelium, so it is used for preparation and cultivation After feeding, the mycelia tend to grow slowly and weakly, and the final yield is not high
Mushroom farmers generally use the method of long-term open-air accumulation and natural fermentation to decompose wood chips, which generally takes more than 6 months, which consumes time, space and funds
Especially for large-scale and continuous production of industrial edible fungus enterprises, there is no wide space, sufficient funds and ample time to support the natural decomposition of wood chips, and they often deal with it by partially sacrificing output and quality

Embodiment 1
[0020] Step 1: Fresh wood chips are fully poured with water, sprinkled with urea while turning over the pile, according to a preferred embodiment of the present invention, the amount of urea is 1.0-1.5kg / m 3 , the added urea is to ensure that ammonium nitrogen provides a nitrogen source for microorganisms related to decomposing, promotes their proliferation, and promotes the decomposing of sawdust; mix sawdust and urea evenly.
[0021] Step 2: build a pile of mixed sawdust, according to a preferred embodiment of the present invention, the cross section of the pile is a trapezoid with a width of 5-6m at the bottom, a width of 3-4m at the top, and a height of 1.2-1.6m. The length is set according to the site. After the pile is built, holes of 3-5cm are drilled on the pile surface of 0.5m square to ensure that the wood chips can fully dissipate heat.
[0022] Step 3: Turn the pile when the temperature in the center of the pile rises to 50°C, and rebuild the pile after turning ove...

The invention discloses a sawdust decomposing process, which comprises the following steps of: fully soaking fresh sawdust with water, scattering urea during stack turning, and mixing uniformly; stacking the mixed sawdust, and punching holes on a stack surface after stacking; turning the stack after the central temperature of the stack rises to 50 DEG C, and restacking after stack turning; turning the stack when the central temperature of the stack rises to 50 DEG C once again, adding white-rot fungi agent during stack turning, mixing uniformly, and stacking; and turning the stack and stacking once 15 days later, and ending decomposition another 15 days later. / the decomposing process adopted in the invention has simple steps, is convenient to operate, and is easy for controlling decomposing process conditions; only a small amount of the urea and the white-rot fungi agent are used, so that decomposition of the sawdust with microorganisms is facilitated, and the cost is low; the sawdust decomposing time is shortened, and is only about 40 days, the land occupation of sawdust decomposition is reduced, and the process can be applied to large-scale and continuous production factory-like edible fungus enterprises; and when decomposed sawdust is used for cultivating strains, the yield and quality of the strains are improved.
Description
technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a process for rapidly decomposing wood chips. Background technique [0002] At present, in the production of edible fungi, especially the production of wood-rot fungi, because fresh wood chips are impure or contain a large amount of substances that inhibit mycelium growth, and the structure of wood chips is tight, it is not easy to be decomposed and utilized by edible fungus mycelium, so it is used for preparation and cultivation After feeding, mycelium often grows slowly and weakly, and the final yield is not high. Mushroom farmers generally use the method of long-term open-air accumulation and natural fermentation to decompose wood chips, which generally takes more than 6 months, which consumes time, space and funds. Especially for large-scale and continuous production of industrial edible fungus enterprises, there is no wide space, sufficient funds and ample...
