Yellow-backed Auricularia is a medium-high temperature type fungus that adapts to a wide range of temperature; the primary fruiting body is cup-shaped and gradually grows into ears. Many ears are daisy-shaped together; the diameter is generally 10 cm to 20 cm. After drying, it is strongly contracted into keratin, hard and brittle; the back of fruiting body is raised, with short villi, smooth surface or veined wrinkles; the color is dark brown, brown, light brown, yellowish due to different varieties and planting methods. Wait. The yellow back fungus on the market is relatively scarce. Now the main points of its cultivation techniques are described as follows: 1. The best ear season for yellow-backed fungus in the cultivation season should be from the beginning of summer to the autumnal equinox. Therefore, the bacterial culture (up to 40 days after inoculation to full-grown bacteria) can be planted after the Spring Festival. If the planting volume is large, it can start one month before the Spring Festival. Before the Spring Festival, the mycelium bags full of mycelium should be strictly prevented from freezing. After the Spring Festival, a shade canopy can be placed on the back of the house or on the open space. When placing the bacteria bag, a certain gap must be left between the row and the row. Above the fungus bag, it can be covered with a woven bag. The bacteria bag full of mycelium is not afraid of the rain. If the spring drought does not rain, sprinkle water as appropriate. Second, the preferred variety selection of mycelium growth robust, ear early, strong resistance, short growth period, good flowering, high yield varieties, such as Shanghai 3, 781,952 and other strains. Third, the culture material configuration in accordance with the growth and development of yellow back auricular need for carbon and nitrogen ratio, according to the advantages of local resources available on-site selection. Commonly used bag material formula is: 1 cotton shell, sawdust, corn cob each 1/3, sugar 1%, lime powder 2%. 2 25% cotton seed shell, 35% corn cob, 36% sawdust, 1% sugar, 1% gypsum powder, 2% lime powder. Fourth, the production of bacteria bags will be corncob lime soaked in advance, and then sawdust, cotton shell and a variety of accessories, mix and mix. Moisture should be controlled within 3-4 hours after mixing, and hand-grip the water from the fingers. The pH after sterilization is 6-6.5. If there is any difference, adjust the amount of lime. It is strictly prohibited to add carbendazim, thiophanate and other pesticides. The specifications of the plastic bag are 20 cm and 42 cm (each bag can hold 800 grams of dry material, 150 grams of dry ears can be produced). The bag should be tight and tight, and the mouth rope should be fastened. After atmospheric pressure sterilization reaches 100°C, keep it for 11-12 hours. Use bacteria or potassium permanganate to sterilize bacteria. Don't rub the bacteria too much, but don't have large chunks. Appropriately increase the amount of inoculum so that the strains are preferentially covered with the material surface, which can effectively prevent the invasion of bacteria and reduce the bad bags. Early spring to inoculate warm inoculation, late spring need to cool and then pick up. Fifth, the bacteria period management (1) greenhouse and temperature: bacteria bags into the room for the first few days, the room temperature must be 25 °C -28 °C, so that the bacteria in the best conditions, the fastest germination, colonization. After the mycelium is released, the temperature drops to 18°C-22°C. At this temperature, the mycelium is white and robust, and the yield is high. In terms of temperature, the temperature in the first few days determines the success rate, and the subsequent temperature determines the level of output. (2) Light and ventilation: Light should be dark. Light is an important factor in the formation of fruit bodies. Controlling light intensity can control the formation of fruit bodies and reduce nutrient consumption. Fungus is an aerobic fungus, which requires sufficient oxygen during its entire growth and development. Therefore, regular ventilation and ventilation should be performed 1-2 times a day. The outside temperature is high in spring and ventilation can be selected at night. (3) Inspect the bacteria in time: The bacteria bags often contain the contamination of bacteria. They must be checked in time and gently handled to prevent damage to the wall of the bag. If a mouse is found to be a hazard in the greenhouse, lime must be applied in a timely manner so that the surface of the fungus bag is covered with a layer of lime to prevent its damage.
