The echinocandin isolated from Auricularia auricula has antifungal effect. The following is to introduce the cultivation method of auricularia auricula for everyone, hoping to help everyone.
Cultivation method of Auricularia auricula: First cultivation soil: sawdust 78%, wheat bran 20%, sucrose 1%, gypsum powder 1%, urea 0.4%, water1:* *1.3 *.
Second: 80% cottonseed hull, 0/8% wheat hull/kloc-0, 2% gypsum powder, 0.3% lime, and the feed-water ratio is1:* *1.2 ~1.3 * *.
Third: 66% of rice straw, 32% of rice bran, gypsum powder 1%, calcium superphosphate 1%, and the water consumption per 100kg of rice straw is 130 ~ 160kg.
Fourth: 50% corncob, 28% cottonseed hull, 20% wheat husk, 1% sucrose, 1% gypsum powder, and the feed-water ratio is1:* *1.2 ~1.3 * *.
When preparing the culture medium, the water content should be controlled within 60%, and it is advisable to hold it in Marie Laure Gigon. The water content of rice straw and bagasse as raw materials is based on the water line between fingers and no dripping water.
Cultivation method of auricularia auricula: Plastic bag cultivation changed the history of auricularia auricula production by wood, and made auricularia auricula cultivation move from forest area to field. Auricularia auricula planted in plastic bags are made of sawdust and straw, and packed in plastic bags, each bag contains 0.5 kg of dry materials. After sterilization, inoculation and bacterial culture, it is placed in fields and orchards. The technology of cultivating Auricularia auricula in plastic bags has greatly expanded the cultivation raw materials and area of Auricularia auricula, greatly shortened the production cycle, returned to the natural cultivation mode, and realized natural pollution-free, which is more conducive to large-scale, mechanized and standardized production and has broad development prospects.
The cultivation of auricularia auricula in plastic bags was successfully invented by Chaoyang Edible Fungi Research Institute of Liaoning Province. 1994 was listed as "national key promotion plan of scientific and technological achievements" and "seventh five-year poverty alleviation plan", and in the same year it won two national invention patents * * * ZL 94 1 1092. 8; ZL 94 1 10204 .5*** was awarded "Top Ten Excellent Scientific and Technological Achievements of National Edible Fungi Industry" in 2000, and was awarded and supported by the World Bank, the State Council Poverty Alleviation and Development Group and Ministry of Civil Affairs in 2006. The cultivation of auricularia auricula in plastic bags conforms to the life habit of auricularia auricula "cold, hot, dry, wet and dry" in the way of "coming from nature and returning to nature", and has become the mainstream of auricularia auricula cultivation with high success rate, high yield and good quality.
Cultivation method of auricularia auricula: Inoculate auricularia auricula with substitute to cultivate auricularia auricula. It only takes 45-55 days from inoculation to fruiting, and the production cycle is 100- 120 days, which is 50%-60% shorter than the original production time. The original 1 season was changed to spring, February and September. Inoculate in autumn from August to September, and the fruiting body grows in June 10~ 1 1, but avoid high temperature; The temperature is low in early spring and can be adjusted by heating. The optimum temperatures for mycelium growth and fruiting body growth of Auricularia auricula were 22~30℃ and 20~25℃, respectively.
Cultivation method of auricularia auricula: cultivation of Tilia amurensis. Artificial cultivation of Auricularia auricula originated in China around 600 AD. It is the earliest cultivated edible fungus variety in the world, with a history of 1400 years. In the Tang Dynasty, the villagers in Daba Mountain, Micang Mountain and Longmen Mountain in northern Sichuan all used the method of "cutting flowers with logs" to grow auricularia. This primitive planting method lasted for thousands of years. In Qing Dynasty, auricularia auricula was also planted in Changbai Mountain in Northeast China and Funiu Mountain in Henan Province. When deciduous trees are cut down for three or nine days in winter, auricularia auricula spores naturally reproduce. The output is extremely low. From 65438 to 0955, Chinese scientific and technological workers began to cultivate solid pure strains of Auricularia auricula, and invented the drilling inoculation method of basswood, which greatly improved the yield of Auricularia auricula cultivated in wood segments. But after two or three years to complete a cycle, the absolute output is still not high. Each high-quality wood segment with a length of 1m and a diameter of 10 ~ 13cm only produces Auricularia auricula100 ~150g in three years, and the yield is often reduced due to natural disasters. So far, this method has only been popularized in a few ear farmers in forest areas.
Cultivation methods of auricularia auricula: bagging sterilization and indoor fungus growth 1. Bagging cultivation bags are made of low-pressure polyethylene and polypropylene plastic film bags, the specifications are: bag mouth width 12cm, length 50cm, plastic bags 1kg per 100kg raw materials.
The package should be firm, with 4~6 inoculation holes punched on the surface of the bag, with a width of 1.5cm and a depth of 2cm, and sealed with adhesive tape. After bagging, put it into an atmospheric sterilization pot, keep it at 10~ 12h at 100℃, and then inoculate it when it is cooled to 22℃ to select excellent and high-yield strains.
2. After inoculation, bacteria will grow indoors for 4~5 days, and the room temperature should be 25~28℃, not exceeding 32℃. After the sixth day, drain the bag, cover the doors and windows with gauze to prevent direct glare, pay attention to ventilation, and the indoor relative humidity is 75%. After 20 days of culture, the mycelium grew into a circle in the bag. When the diameter is 8~ 10cm, leave a small gap on the adhesive tape, let it ventilate and increase oxygen, and accelerate the growth of mycelium. After 40 days, the adhesive tape was peeled off at room temperature of 20~23℃ and relative humidity of 80%.
