The benefit of making good use of space is doubled to grow Coprinus comatus under black fungus.

The construction of the shed is semi-underground. Dig 60 cm from the ground and build adobe on three sides, high in the north and low in the south. Dig the border in the shed, the border is 80 cm wide and 35 cm deep, and the corncob is dried and crushed to the size of soybeans. The corn straw is dried and rootless and crushed into 3 to 5 centimeters long. Culture material formula black fungus formula: corncob 45%, hardwood sawdust (or cottonseed husk) 30%, wheat bran 15%, corn flour 5%, phosphate fertilizer 1%, lime 2%, gypsum 2%, sugar a little, potassium dihydrogen phosphate 0.1%. Soak the corncob in 2% lime water for more than 10 hours. Then mixed with other materials into a 17 × 35 cm low-pressure polyethylene bag, sterilized under normal pressure for 8 hours, cooled and inoculated under aseptic conditions. After inoculation, it was put into the culture room for bacteria, and the room temperature was kept at about 23 ℃. Coprinus comatus formula: 3.5 kg of crushed corn straw, 5 kg of wheat bran, 2 kg of lime, 0.5 kg of gypsum, a little sugar, 2.5 kg of dried chicken manure, 0.5 kg of phosphate fertilizer, 1.5 kg of cake fertilizer, 50 grams of potassium dihydrogen phosphate, 100 grams of urea and 50 grams of carbendazim. The corn stalks were soaked in 3% lime and 0.1% chlorpromazine water for 10 hours. after water control, they were mixed with wheat bran and dried chicken manure and fermented. When the material temperature reaches 60 ℃, turn the pile after 8 hours and repeat it for three times. Add other accessories every three times when turning the pile. The fermented noodle is brown, has no peculiar smell, and the water content is 65%. The material temperature is below 28 ℃ and put into the border. The bacteria were put into the material by the combination of layer sowing and hole sowing (7.5 kg bacteria for every 50 kg dry material). The material was 30 cm thick. The material surface is covered with newspaper and agricultural film, and the temperature in the shed is kept at about 20 ℃ to cause bacteria. Management (1) after the bag of Auricularia auricula is full, begin to go into the shed to lift the bag, 8 for each rope. Used for soda water to wash bags and disinfect. Each bag is marked with 8 "ten" according to the shape of "product" and goes out of the ear. (2) after the Coprinus comatus is full of bacteria, insert a hole 3 cm deep every 30 cm, and add nutrient solution. The material surface is sprayed with triacontanol and gibberellin to increase the yield and turn tide quickly. Auricularia auricula cultivation 50 kg dry material to produce 5 kg dry ear, Coprinus comatus every 50 kg dry material to produce fresh mushroom about 60 kg. The production of Auricularia auricula and Coprinus comatus with corncob and cornstalk has a wide range of raw materials, simple method and low cost.
