Fungus bag cultivation method for supplying oxygen to edible fungi in whole process

Abstract

The invention discloses a fungus bag cultivation method for whole-course oxygen supply of edible fungi. The fungus bag cultivation method comprises the following steps that S1, raw and auxiliary materials for edible fungi cultivation are prepared; s2, filling plastic fungus bags with the raw and auxiliary materials, and sealing the plastic fungus bags to obtain cultivation fungus bags; s3, double-faced adhesive tape is pasted on the lower end faces of pile caps of the nail-shaped sand filter sticks, then the nail-shaped sand filter sticks are inserted into the deep position of the cultivation fungus bag, the pile caps of the nail-shaped sand filter sticks are tightly pasted with the plastic outer film, and so on until 3-5 nail-shaped sand filter sticks are inserted into the cultivation fungus bag at intervals; s4, sterilizing the cultivation fungus bag inserted into the nail-shaped sand filter stick in the step S3 at the high temperature of 120 DEG C for 1 hour, naturally cooling the raw and auxiliary materials in the fungus bag to 25-30 DEG C, transferring the fungus bag to a sterile environment, opening a seal, inoculating edible fungi, and sealing again; and S5, placing the cultivation fungus bag inoculated in the step S4 in a culture room for mycelium culture. Therefore, by shortening the growth period of the hyphae and improving the growth state and quality of the hyphae, the situation that traditional air holes are exposed and polluted by mould is avoided, and the yield of the edible mushrooms is increased.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and particularly relates to a fungus bag cultivation method for the whole-course oxygen supply of edible fungi. Background technique [0002] Edible fungi are aerobic fungi, which require a certain amount of oxygen supply during the growth process to grow robustly. In many years of actual production, it is not difficult for us to find that the bacteria bags after receiving the bacteria are in the process of growing, and some bacteria bags that have been gnawed by mice will grow much faster than normal in the absence of contamination. , the hyphae are also robust and powerful. Due to the artificial cultivation of edible fungi, there are many harmful molds, and these molds are more competitive. They not only compete for nutrients with the edible fungi mycelium, but also secrete toxins to inhibit or poison the edible fungi mycelium. Therefore, the only way to succeed in cultivating edible ...

AI Technical Summary

Problems solved by technology

However, due to the limitation of sealing material for bagging sterilization, inoculation, and cultivation of mycelium with edible fungus cultivation material, the inserted bacteria mainly rely on the limited oxygen stored in the interstitial space of the culture material in the fungus bag to maintain life activities, and the treatment effect is not ideal. , there are problems of insufficient oxygen supply and low yield

In the early stage of mycelium growth, life metabolism is at an extremely low level, and this oxygen supply situation has no obvious impact on mycelium growth. The main manifestations are: 1) The oxygen supply required for mycelium growth is insufficient, the mycelium grows slowly or stops, the mycelium ages, and the disease resistance becomes poor. to play

2) The breathable bag is a plastic bag that is placed close to the breathable material because it is difficult to seal the joint between the periphery and the plastic bag, and it is easy to leak air and cause pollution; in addition, when the hyphae grow to the breathable material, it will lose its breathability. Therefore, the application of this method still does not achieve the effect of promoting mycelial growth.

① Every time a certain stage of growth is reached, it is necessary to puncture the holes to increase oxygen once. Edible fungi such as cultivated long mushroom sticks need to pass through more than three times of puncturing (in actual production, the water content of the mixing material is too large, the filling is too tight, and the raw materials In the case of small particles, the oxygen in the material is reduced, and the oxygen supply of the hyphae only by the above method is only "a superficial" or "nowhere near itching", and it is difficult to solve the fundamental problem

Therefore, it requires a lot of manpower and material resources

② There are limitations in the selection of the piercing position and certain technical requirements for the depth of the piercing, which are generally difficult to grasp

In addition, it is not easy to control the amount of water injected into the fungus sticks, and it is not uncommon to see the phenomenon of rotten sticks due to unsuitable water replenishment.

④ Easy to pollute and cause great loss

Due to a large number of holes in the fungus sticks, when the temperature of the culture environment changes, condensation water is easily produced at the hole holes and physiological water is easily produced when the mycelium is stimulated, which creates a pollution opportunity for the mold, resulting in production losses.
