Seed production: there are sawdust strains and branch strains. The former is made of sawdust and wheat bran. The latter is cut into branches with a length of 1.5cm and a diameter of 1cm, added with nutrients such as sucrose and rice bran, bottled, autoclaved, inoculated with mother seeds, cultured at 25-28℃ for one month, and mycelium can grow in the bottle. Selection of cultivation place: The place for cultivating Auricularia auricula should be below 1000 meters above sea level, with long illumination time, less shade, warmth, small temperature difference between day and night, high humidity and abundant Auricularia auricula resources, so it is best to be close to water sources. Preparation of auricularia auricula: There are many kinds of auricularia auricula trees for cultivating auricularia auricula, and all kinds of trees that can cultivate mushrooms can be used to cultivate auricularia auricula. Mainly select FAGACEAE and betulaceae tree species, such as Quercus acutissima, Quercus variabilis, Quercus acutissima, Castanopsis carlesii and Quercus acutissima. In addition, Pterocarya stenoptera, Liquidambar formosana, Ulmus pumila, Sophora japonica, willow, mulberry, Platanus acerifolia and Ficus microcarpa are also commonly used tree species in the production area. Inoculation: Artificial inoculation is the key process of cultivating Auricularia auricula, and it is also the biggest feature of the new cultivation method. When the temperature is stable above 65438 05℃, the inoculation time is generally beneficial to the growth of auricularia auricula mycelium. The specific time varies with different climatic conditions, and the southern provinces are probably in March-April. Colonization management: After inoculation, Auricularia auricula must be stacked in order to maintain high temperature, high humidity and enough air, promote the early emergence and colonization of strains in Auricularia auricula and improve the survival rate. The method is to arrange the inoculated auricularia auricula into a well-shaped frame and pile it in layers into a small pile with a height of one meter. Dry and wet thermometers are hung in the pile, and the periphery is closely covered with film. The reactor temperature is controlled between 22-28℃, and the relative humidity of air is kept at about 80%. There should be a gap of 5~6cm between auricularia auricula to facilitate good ventilation. Scattering and ostentation: Difficulty and ostentation are the continuation of heaping, which aims to make hyphae spread to the depths of Auricularia auricula and make it quickly change from growing period to developing period. The venue for ostentation and extravagance should be sunny, damp and properly sheltered. When ostentation and extravagance, the ear tree should be laid flat on the ground and covered with short grass. If it is soil, first put a small wooden pole horizontally, and then put the ear wood on the crossbar one by one, with a spacing of 6~8cm. Ear management: After the fungus is erected, it has reached midsummer, with high temperature and dry weather. It is necessary to use automatic sprinkler irrigation to spray water in time, require long-term spraying and fine spraying, so that auricularia auricula can absorb enough water and promote the occurrence of auricularia auricula buds. Sprinkle more water during the ear mat growth period, more water in the dry and high temperature season, less water on cloudy days, and no water during the dormancy period of auricularia auricula. Water spraying should be carried out in the morning and evening.
