Abalone mushroom processing technology

<

(1) During the cultivation season of abalone mushrooms in cultivation season, the suitable sowing period can be arranged according to abalone mushrooms normally at 25-30°C, generally suitable for a period of 5-10 months each year, and fruiting vegetables cultivated from mid-May to July. The yield is relatively high, and the yield from August to October is relatively low, because the high temperature weather and the low temperature effect in mid-October are often encountered during this period.

(2) Cultivation methods Cultivation of abalone mushrooms uses bag planting methods. Fruiting on the bed frame can make full use of space. Mushrooms should be provided with ventilation windows, and the surrounding environment should be cleaned to reduce the sources of pollution. Mushroom Shelter should be located north to south, although Abalone mushroom is a high-temperature type mushrooms, but the strong sunlight in the summer, the temperature often exceeds the abalone mushroom hair temperature range, unfavorable for mushrooming, mushroom shed north south easy to avoid yang and ventilation.

(3) PDA culture medium is used for the production of parent strains, supplemented with 0.2% peptone, and the mother mushroom of Abalone is prepared according to the conventional method of making parent species of Pleurotus ostreatus. Both the original species and the cultivated species can use ordinary sawdust medium, ie, 74% of broad-leaved wood chips, 24% of bran, 1% of sugar, and 1% of calcium carbonate. Grain media can also be used. The production process is the same as that of mushroom and other edible mushrooms.

(4) Cultivated formula uses different main materials to cultivate abalone mushrooms, and their yields vary greatly. According to experiments, the use of the following types of cultivation materials formulation higher mushrooms.

1. Cotton shells or waste cotton 93%, bran 5%, sugar 1%, calcium carbonate 1%.

2. 405% of cotton shells, 40% of broad-leaved wood chips or bagasse, 18% of bran, 1% of sugar, and 1% of calcium carbonate.

3. Broad-leaved wood chips 73%, bran 20%, corn flour 5%, sugar 1%, calcium carbonate 1%.

4. Straw powder 37%, broadleaf wood chips 37%, bran 20%, corn flour 4%, sugar 1%, calcium carbonate 1%.

5. Wheat Straw (crushed) 25%, Bean Straw (crushed) 25%, Corn Cob (crushed)

25%, 12% of wood chips, 10% of bran, 1% of lime, 1% of superphosphate, and l% of gypsum powder.

6. Sterilization by bagging According to the formula, the pre-moisturizing sucks the water first, and the water content can be adjusted to 65%-70% to bagging. Bag size is 20x33x0.05 or l7x33x0.05 polypropylene film bag.

Sterilization, inoculation, and germination are the same as normal. Generally 25-30 days, the hyphae can be sent to the bottom of the bag. When the mycelium reaches a physiological maturity, the mushroom shed can be used for mushroom management.

(6) Mushroom management Abalone mushrooms are not the same as other oyster mushrooms. It is not appropriate to open holes in mushroom bags, because the openings do not necessarily grow fruit bodies, and often there are only stigma conidiophore stalks in the openings, which cannot be developed into Sub-entity. Should not be taken out of the bag mushroom, otherwise the entire surface of the mushroom will grow conidial stem bundles and droplets containing conidia, is the occurrence of fruiting bodies, the number of flowers is very small.

The method of mushrooming on the surface of the culture material is to remove the tampon, remove the collar, straighten the film of the bag mouth, and roll it up to the surface of the culture material. The handle that has grown out of the material surface is slender, without a cover or a small cover. The younger son of the entity, and spray moisturizing, spray 3-4 times a day, spray water and then drain the excess water in the bag. Mushroom temperature control in 27-32 °C, 20 °C below the occurrence of mushroom buds, 20-25 °C mushroom buds occur less, more than 32 °C mushroom buds are also difficult to occur, so a good control of the mushroom temperature is the key. The relative humidity of the air is adjusted to about 90%, and the amount of water spray and the number of water sprays must be increased with the growth of the mushroom body. Can not have direct sunlight. Usually 8-10 days begin to mushroom, 6-8 days after bud emergence can pick mushrooms. The first wave of mushrooms after harvest to restore the mycelium 2-3 days and then spray water management, 12-15 days after the second tide mushroom. The third mushroom in the general trend is relatively less.

(7) Pest control The temperature of mushroom abalone and mushrooming period is relatively high. In the high-temperature and high-humidity environment, it will be difficult to control once the pests and diseases occur. Preventing pests and diseases is very important. First of all, it is required to use fresh, mildew-free main ingredients during stock preparation. Before the cultivation, the inoculation box, the bacteria chamber, the cultivation shed and the bed frame shall be cleaned and then fumigated. The dosage is 10 g of sulfur or 10 ml of formalin per cubic meter of space, and the spray is sprayed before fumigation. Wet space enhances sterilization. In addition, all doors and windows should be woven with denser nylon mesh to prevent fly and mosquito trapeze. Once bacteria bags of bacteria and insect pests are found, they should be taken out of the house in time to prevent spoilage.

(viii) Harvesting and processing of abalone mushroom mushroom covers nearly flat and the edge of the cover is slightly rolled inwards. If the spores are matured and ejected and then harvested, not only the product value is low, but also the mushroom body has a bitter taste, and the spore flying will affect the health of the mushrooms.

The whole production cycle of abalone mushrooms is about 3 months, and the biological efficiency is 70%-90%.

The portion of the mushroom culture medium that has been removed by the mushroom is ready for sale. Can also choose mushroom cap diameter 3-5cm, handle length 1-2cm mushroom body processed into brine mushroom or made canned export export, its processing technology and other oyster mushrooms the same.
