NOVELTY - A culture material of Auricularia auricula comprises (in parts weight) weed-tree sawdust (45-50), maize straw powder (35-50), wheat bran or rice chaff (10-15), corn powder (1-3), gypsum (1) and lime powder (0.5-1).    USE - As culture material of A.auricula.    ADVANTAGE - The culture material of A.auricula is cost-effective and environmental-friendly.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of culturing A.auricula, which involves mixing gypsum and wheat bran or rice chaff, laying sawdust and maize straw powder on cement ground and spreading corn powder, lime powder and mixture of gypsum and wheat bran or rice chaff on the sawdust and maize straw, and mixing raw materials, piling and curing layered piling material for 1.5-2 hours, adding water to adjust the water content of culture material to 63-65%, after curing the mixture, filling culture material in polyethylene bags manually or by a bag packer, sterilizing mixture at 100 degrees C and normal pressure for 12 hours, inoculating strain in sterile environment when the material is reduced to room temperature, one bag of strains is inoculated to 40 bags, 1/3 of strains are inoculated in the holes and 2/3 of strains are coated on the material surface, transferring fungus bag in a culture room to form fungus, where the culture room is shaded, the growth of the hypha is restrained when room has too much light and primordium is easily produced at later stage of fungus growing period, the temperature in room is more at beginning period and less at later period, the temperature of culture room at beginning of fungus growing period is 25-27 degrees C and hypha is quickly planted and fed with materials, the temperature of room is gradually-reduced to 22-24 degrees C after 7-10 days, the humidity in room is maintained to 60-70 wt.%, the fungus is easily-polluted when the humidity is too high, and the water of culture material is easy to evaporate when the humidity is too low, ventilating the room for 1-2 times every day for 30-60 minutes after 7-10 days, the bag is full of hypha after 40-60 days and the hypha is matured physiologically after 10-12 days, choosing seven pieces of lands, 1/3 of lands is shaded, preparing land and setting bags, cutting bags and placing bags with intervals of 2-3 cm and intensively-cultivating A.auricula, covering a plastic film on the bags, covering straw screen or sunshade net to maintain temperature and humidity such that the temperature of land is 26 degrees C or less, spraying water on the straw screen to reduce the temperature when the temperature is too high, cutting the bags after 5 days, ventilating for 2-3 times every day to maintain relative humidity of land to 85-90 wt.%, the cut of bag is not watered when watering land to increase humidity, basically-forming the primordium after 10-12 days, dividing lands and managing them independently, maintaining distance between bags to 20-25 cm, flexibly-managing water jet capacity when maintaining the land, frequently-spraying more water at beginning period, spraying predetermined amount of water to just wet the leaf and spraying more water at night when the A.auricula leaf has length of 4 cm or more, and when the leaf is completely-expanded, watering is stopped and A.auricula leaf is harvested. The A.auricula is an aerobic fungus. The tightness of upper and lower portions of bag is uniform. The bag filling height is 4.8-5.2 cm. The net weight of the filled bag is 750-850 g. The opening holes for inoculation and ventilation are formed in the bags. The ring and a tampon or closing string of the bag is connected to close the filled bags.
