Abstract

By pressing rice straw with a pressure roller mushroom mycelium easily penetrate into the deep parts of the straw. The softened rice straw is then crossed and piled up maximize the oxygen provision and water content and to evenly distribute adsorption of the mycelium. Pressed softened rice straws are crossed and piled up, and a mixture of broadleaf tree sawdust 1% and rice-polish 0.5% are sown. It is then sterilized at 60-70≰C for 5-6hr retaining a moisture of 70-80%.

Description

How to grow oyster mushroom culture medium

The present invention squeezed rice straw, which is agricultural waste, with a pressing roller, so that the mycelia of oyster mushrooms can easily penetrate deep into the rice straw, and weave the softened rice straw and weave it with cotton yarn to supply oxygen. It relates to a method for producing oyster mushroom cultivation medium that can increase the yield by maintaining the moisture content of the mycelia uniformly.

Conventionally, as a medium for mushroom cultivation, holes in oak and rapeseed trees were dug and cultured by sticking mycelia to the holes, so the medium itself was hardened, so the sticking time was prolonged and moisture control could not be maintained properly. For example, rice straw is grown as a medium, namely 0.5-1cm of rice straw, hardwood, sawdust, rice bran, calcium carbonate, benomil, moisture and adhesives into a mold of a constant size of 10-25kg / cm ² The method for preparing oyster mushroom cultivation pots (notification number: 82-530), which is molded under pressure and sterilized at a temperature of 120-130 ° C. for one hour, and then packaged in a sterile PP film after hot air drying, is disclosed here. When the compound is pressurized at the pressure, the medium itself hardens as if it is wood, so poor water penetration leads to weak capillary action. As the spawning activity is very slow as in the case of using wood, the medium is sterilized for one hour at 120-130 ℃, but it is difficult to heat to 100-130 ℃ by the usual medium heating method. The heating time also did not reach the normal sterilization temperature, and the use of flour paste as an adhesive increased the bacterial growth and caused enormous disruption to mycelial growth. In order to correct this end, the present application compresses rice straw, which is hardened like wood, in a pressing roller to make a softening material of 0.5cm thickness, so that hyphae is easily absorbed by facilitating infiltration and water content of hyphae. The softened straw is so thin that it crosses horizontally and vertically until the thickness is about 5-l0cm, and then weave it with a cotton yarn to weave the oxygen supply passage during mycelial activity. Since it is possible to maintain the enemy, the hyphae of the hyphae are evenly adhered to the depth of the medium so that they can be cultivated and harvested early.

[Step 1]

The rice straw was pressed with a pressing roller to cross-write softened rice straw with a unit thickness of 0.5 cm to an appropriate width, and then sprayed onto a soft rice straw, which was mixed with 10 parts of hardwood sawdust and 5 parts of rice bran, and applied to the softening rice straw. The softened rice straw is small, about 5-10cm high, and then weaved the small layers with a cotton thread 4-6cm apart so that a slight gap is formed between the weaves.

[Step 2]

The medium produced in the first step is heated at a temperature of 70-90 ° C. for about two hours to sterilize various germs and larvae remaining in the medium, and then cut to a suitable size.

[Step 3]

Sprinkle on the first sterilized medium to make the content of the medium 70-80%, sterilize it for 5-6 hours at the temperature of 60-70 ℃, inoculate spawn and package it in sterile wrapping paper.

As described above, the present invention compresses rice straw as a softening material and softly sterilizes softening rice straw and medium under appropriate temperature for two times, and then writes down the pressed rice straw and cross-stacks the known hardwood sawdust and rice bran. After spraying the mixture of, and accumulating the height of the crossover height of about 5-10cm and weaved with cotton yarn, the space is formed in the red layers, but the gap is formed between the weaving and capillary action when water is sprayed on the medium. Compared to the conventional one, the inoculation of hyphae keeps moisture suitable for mycelial growth in the deep layer of the medium, so that the hyphae evenly evenly spreads to the deep layer of the medium, and the oxygen formed at the interval formed between the interweaving layer and the interweave. The supply is smooth and the military's upheaval is further increased.

Claims (1)

Compress rice straw with a pressing roller and cross-write softened rice straw with a unit thickness of 0.5 cm to a suitable width. -10cm, and then weaving this small layer with a cotton yarn at intervals of 4-6cm and squeezing it first for about 2 hours at a temperature of 70-90 ℃, and 5-6 hours from 60-70 ℃ at a classification content of 70-80%. Method for producing oyster mushroom cultivation medium, characterized in that the secondary sterilization.
