How to grow Coprinus comatus in fermentation bag

1. Cultivation time and strain selection (1) according to the actual situation of mushroom farmers, they are respectively put into production in winter, spring and autumn. Because Coprinus comatus has the characteristics of not covering soil and not producing mushrooms, large-scale bacteria bags can be made in idle time. According to market demand, cover soil and produce mushrooms 20-30 days in advance. (2) the varieties with large mushroom body, moderate individual, few scales, disease resistance and high yield were selected, solitary varieties were selected for fresh sale, and clump varieties were selected for salinization.

Second, culture material formula 1: cottonseed shell 58%, corncob 30%, potassium nitrate 2%, fermented dried chicken manure 10%; formula 2: cottonseed shell 99%, diammonium phosphate 1%; formula 3: Pleurotus ostreatus or Pleurotus eryngii or Pleurotus ostreatus waste 30%, cottonseed shell 39%, corn core 30%, potassium nitrate 1%. The above formulations all add 0.15% 0.2% carbendazim or 0.1% carbendazim 10 ml. When seasoning, the amount of lime powder is 5%, and the amount of water is 65%-70%.

Third, mixing and fermentation are mixed in batches according to the size of the site. When the temperature is high, it is suitable to mix 1500kg to 2000kg at one time, and 5000kg to 6000kg at low temperature. In this way, relatively speaking, the raw material at both ends of the stack is relatively less, and the success rate of cultivation is high. On the second day after mixing, the dried fermented chicken manure was sprinkled and stirred evenly. On the third day, the temperature of the material was raised to 65 ℃ and maintained for two days. After turning, the pH value was adjusted to more than 9. After the material is fermented, the temperature should be cooled in bulk in time, and the material surface should be sprayed with chemicals to prevent disease and insect pests.

Fourth, bagging and sending bacteria (1) bagging. The size of the plastic bag is 22 cm x 45 cm or 25 cm x 50 cm (depending on the temperature). It is necessary to make a good seasoning and disinfection, fasten the bag tightly, pierce the hole in time, and cross or put the packed bacterial bag into the shape of "product". No matter which bagging method is used, the material temperature should not exceed 30 ℃, and the hole should be pierced with bagging. After bagging, the site should be cleaned up, the inside of the shed should be disinfected with aerosol, and the outside of the shed should be re-sprayed with pesticides and fungicides. (2) germs. 1. Temperature. The temperature during the period of mycelium germination should be kept at 25 ℃. After the cover of the mycelium, the growth temperature should be kept at 22 ℃. After half of the mycelium germination, the temperature should be kept at 18 ℃ ~ 20 ℃. two。 Humidity. During the germicidal period, the shed should be dry, the humidity should be kept below 70%, and the humidity should be controlled by ventilation. 3. Air. The air in the shed should be fresh, ventilated frequently when the temperature is high, less ventilated or not ventilated when the temperature is low. The environment should be alkaline. 4. Light. You don't need much light during the germ season. If the grass is opened in order to increase temperature, it can cover sunshade net or dry, sterilized color greenhouse film or old film or black film with poor light transmittance to block the strong light. Waiting for the bacteria bag is silver-gray, the whole body is gradually white, unlock the mouth of the bag can smell a special fragrance, the elasticity of the hand means that the bacteria is successful.

5. Preparation of covering soil (1) if it is a new shed, you can dig the soil on the spot in the shed, break the soil with an iron rake, dig a layer, spray once, and gather the soil to the edge of the border. (2) after the soil is dug, disinfect it with 2% lime powder, spray 5% formaldehyde solution, insecticide, etc., and then cover the film for 3 days, and then pile it up 3 days later. The standard of covering soil: water content 45%, hold into a ball, fall to the ground and disperse.

6. Take off the bag and cover the soil to produce mushrooms (1) 7 days after the mycelium grows all over the bag, begin to take off the bag and cover the soil. The width of the border should be less than 1 meter, and the ridge should be left in the middle of the border 1.5 to 2 meters wide, which can increase the amount of mushrooms. The border should be re-sprayed with insecticides, fungicides and disinfected with lime powder. Put the bag flat or break it in three dimensions, leave a gap of 2 cm to 3 cm between the bags, sprinkle the soil while putting it, and sprinkle the compound fertilizer according to the proportion of 0.6% of the material. After the bag is placed, it is covered with 3 cm thick soil, sprayed with insecticide and fungicide, and the soil is mended again after the flood is soaked. Seven days later, when the hyphae grew all over the border, the soil was covered for the second time, and the soil was 1-2 cm thick. (2) Coprinus comatus generally produce mushrooms in the shape of clusters when budding, do not spray water directly on the mushroom buds, spray on the wall, ground and air, keep indoor humidity at 85%-90%, keep mushroom temperature at 16 ℃-20 ℃, and maintain appropriate scattered light.
