Interplanting black fungus in orchard

The benefit of planting Auricularia auricula by trenching between orchard rows is considerable. The main cultivation methods are as follows: 1. The original culture material formula is sawdust 78%, rice bran (or bran) 5%, corncob 15%, gypsum powder 1%, sucrose 1%. Weigh all kinds of ingredients according to the above proportion, first dissolve sucrose in water, then stir sawdust, rice bran and gypsum powder evenly, spray sugar water on the material, stir and mix. two。 Bag the culture material into a plastic bag, hit a vent from top to bottom in the center of the material with a small stick, plug it with cotton plugs, and then sterilize. 3. The mycelium culture put the original seed into the sterilized culture material in the plastic bag and put it into the shaded indoor culture. after about 50 days, the mycelium grew full of the whole bag, and then it was transferred to the ear-out stage. 4. Trench in the orchard row to dig 1 meter deep, 1 meter wide trench, trench horizontal frame a number of sticks to be used for hanging bags, two days before the ear will be disinfected once. 5. Dig the ligation line to remove the bacterial bag from the room, soak it in 0.2% topiramate solution for disinfection, and then use sterilized scissors to cut eight soybean-sized holes in the bacterial bag wall. Remove the cotton balls and plastic rings from both ends of the bag, fasten them with a rope about 1 meter long, and move them to the edge of the trench. 6. The hanging bag puts the bacterial bag on the wooden stick of the gutter. The bacterial bag is placed vertically into the trench and divided into four layers, keeping a distance of 20 cm between the bags. 7. The management of the ear period should spray clear water once in the ditch after the hanging bag, with the growth of fungus, the humidity should be increased, and the watering should be a small number of times. The suitable temperature is 23 ℃-24 ℃. Change the position of the upper and lower bags every few days so that they are fully exposed to a certain amount of direct and scattered light. The fan in the ditch should be ventilated every 3 days to ensure the oxygen demand at the ear-out stage. 8. Pick when the earpiece grows to 6cm-12cm and dry after harvest.
