Description

How to grow oyster mushrooms using a nap-themed medium

The present invention is a method of cultivating oyster mushrooms using a medium based on the surface of the cotton as a main ingredient of rice straw, rice husk, hardwood sawdust or hardwood, etc., as additives, rice bran, gypsum, slaked lime, etc. It is about.

There are various methods of cultivating oyster mushrooms. Among them, cultivation methods using hardwood trees such as willow, alder, and poplar trees have the physical properties suitable for mycelial growth of oyster mushrooms. It is pointed out that the high cellulose or hemicellulose content, which is a necessary nutrient, increases the growth conditions of oyster mushrooms, but the harvesting period is long and the yield is not high.

In addition, by attempting a method of growing tree branches using the method of cultivating the mulberry tree harvesting slightly more than the method of cultivating the wood, it is difficult to secure the tree branch is not widely used.

Therefore, many methods using easily available rice straw have been attempted. The method is to bundle rice straw and cut it into 15 cm to 30 cm to grow oyster mushrooms, and to grow oyster mushrooms and to cut the mushrooms on rice straw cut to about 2.5 to 15 cm. Cultivation methods are known.

The method of cultivating oyster mushrooms based on rice straw as described above is easier to purchase than wood or eggplant cultivation methods, and is currently grown in about 800,000 pyeong due to the advantage that a large amount of oyster mushrooms can be harvested in a short period of time. There is a situation.

However, the amount of rice straw is deteriorated or decayed due to rain frequently during the growing season or during the harvesting season, and the cost of rice straw is increased due to the increase in production cost. (B) Pesticide residues in rice straws increased due to pesticides, causing serious problems.

Therefore, the present inventors proposed a method for cultivating oyster mushrooms using notched noodles (notification number: 89-2263) in order to solve the above problems, in which the entangled leaves contain carbohydrates necessary for the growth of oyster mushrooms. Not only does the cellulose ((C ₉ H ₁₀ O ₅ ) n) that the bacteria require have sufficient conditions for mycelial growth, but rather the cotton wool, which is made of short fibers of 3 to 6 mm in length, is better than rice straw. It can be said that it has high porosity and sufficient water supply by oxygen supply and high water retention necessary for cultivation of oyster mushroom.

By the way, the above-described method of the present inventors is not a problem when a sufficient amount of cotton wool is supplied, but as the cultivation area of the locust mushroom increases, the supply rate of the cotton wool is slightly low, so the present invention uses the main material as a cotton wool, and the auxiliary material It is made of rice straw cut to 2.5-15cm, rice hull or hardwood tree branch or sawdust dregs, which is added to the surface of cotton, improving physical properties, reducing the self-heat generated from the surface of mycelial growth during mycelial growth, and breathing in the medium after completion of mycelial growth. However, it is expected to increase the number of mushrooms as a moisturizer and to increase mushroom cultivation area more than twice, and to effectively deal with agricultural wastes, which is expected to be very important in terms of national and national hygiene. If used, the effect will be even greater.

Hereinafter, the manufacturing process of the present invention will be described in detail by the process.

[1st process (medium composition and fermentation process)]

20 to 50 parts of rice straw cut to about 2.5 to 15 cm and 50 to 80 parts of cotton wool are mixed in a ratio of about 65 to 70%.

At this time, when 2 to 5 parts of rice bran is added to the mixture, the microorganisms are decomposed in the medium to facilitate heat generation, and the cellulose is decomposed by the high temperature microorganisms in the medium. Antagonistic action on the plant can prevent the development of green mold disease, which is a serious damage to oyster cultivation.

Then, the medium is stacked using a retirement frame of 1.2 to 2 m in height and 2 m in width, and covered with vinyl and a heat insulating material such as a thermal insulation material, and left unchanged when the outdoor temperature is 15 ° C. or higher. When the temperature is above 50 ℃, the inverting is performed. In the inverting, the bottom compost is uniformly placed at the bottom and the upper one is placed at the bottom to evenly distribute the oxygen supply fermentation such as oxygen supply and harmful gas removal. Turn over and reheat after 2 to 3 days of deposition. When it reaches 50 ° C. or more, turn over again and turn over a total of 2 to 3 times.

[Second process (after sterilization and post-fermentation process)]

Cover the thickness of 0.03 to 0.05mm on the bottom surface of the grower, and then granules with a thickness of 10 to 25 cm along left and right badges and covered with vinyl on the side and top of the medium.

Or in order to reduce the high temperature damage in the summer, put it in a wooden box or P. P box heat-resistant plastic bag and warm it with briquettes or steam to keep the temperature in the medium at 60 ℃ or more, and then sterilize the fungus by the first sterilization for about 10 hours. After killing, stop the heating and lower the temperature to 40 ~ 50 ℃ again, after maintaining the secondary sterilization at 60 ℃ or more for about 6 to 8 hours by the above method, if the post-fermentation is carried out omit the fermentation If no outdoor fermentation is carried out, the temperature is gradually lowered, followed by 2 to 4 days at 50 to 55 ° C. The sterilization gas is removed during sterilization and cultivated after the first sterilization or the second sterilization for fresh oxygen supply. Temporarily open the door, supply appropriate oxygen, heat treatment again, and then start the temperature-lowering operation.

[3rd process (Spring vaccination and mycelial adhesion process)]

After cooling the medium in the fungus medium or box plastic bag sterilized by the grower about 23-30 ° C. according to the season, 10-13 LBS per 3.3 mm ² of the seed is evenly mixed with the seed and the medium, and then the surface of the medium is gradientd. After the composition is sealed so that it is well sealed with vinyl, the initial 7 days of seed inoculation are managed at 20 to 23 ° C, and the middle 7 days are maintained at 27 to 29 ° C for about 6 days at 24 to 26 ° C. .

Fourth Process (Mushroom Development and Harvesting Process)

After the completion of the third process, the hyphae is completely removed, and the vinyl covered with the medium is removed. When the mushroom is generated by irradiating to 150LUX, the indoor humidity is gradually reduced, and the mushrooms are harvested by increasing the ventilation and irrigation amount. Can be produced with mushrooms.

EXAMPLE

If you compare the number of oyster mushrooms with mixed ramen noodles, ramen noodles + rice straw, ramen noodles + sawdust debris, and the number of primitive wednesday weds are as follows.

TABLE 1

Comparison of Initial Yield and Yield According to Badge Production Method (Box Cultivation)

As shown in the above table (1), as the number of the main ingredients of ramen is added, the yield increases, and the tendency is quick to start, and the number of times when flipped 3 times rather than 0 times in 75% of rice straw + 25% of straw and 100% of noodles In many cases, early incidence was increased, and as the ratio of chaff increased, the yield decreased and the incidence of germs increased as the ratio of chaff increased. The reason is that the husk husk itself is hard and is long to be decomposed by microorganisms. Nutrients were found to be less than rice straw or sawdust, and the yield was good at only 95% of the noodles and 5% of the rice hull, because of the rich nutrients and 5% of the rice hulls. This is because the air permeability in the medium during mushroom growth increases the military vitality and water retention after watering is improved and physical properties are improved. In addition, the yield was increased and the early firing rate was higher in 75% + 25% of sawdust and 95% + 5% of sawdust.

Therefore, it is possible to obtain good results by adding small amounts of auxiliary straws, rice husks, sawdust, etc., rather than using the whole quantity, and contributed to the expansion of the growing area.
