1, straw mushrooms withered 1 mushroom bud formation temperature control at 25-28 °C, early fall when the temperature dropped to below 20 °C, in the shed covered straw insulation; 2 bacteria line growth phase should be dark, prevent Strong light stimulation, premature formation of mushroom buds; piled grass should be tight, in order to facilitate the close connection of mycelium; 3 mycelial growth period with fish rattan essence and dichlorvos sprayed around the culture material of the mushroom bed to poison kill Malu and tide insects, etc. Insect pests; 4 species of bacteria must be separated or introduced every year, the enemy, suitable temperature preservation; 5 regularly sprinkle the water around the lump on the lump or irrigation in the ditch, keeping the bed moist, the relative humidity during the maintenance of the mushroom to maintain 90-95%, It is strictly forbidden to use water on the initial surface of bacteria buds; after the mycelium is covered with culture materials, the film covering the material surface shall be peeled off in time to ventilate and ventilate, but ventilation and dryness shall be avoided when the hygienic wind and dry wind are directly blown into the mushroom house. Ventilation combined; 7 culture materials before cultivation should be exposed to 1-2 days, when the ingredients to adjust the PH to about 8-9; 8 mushroom pick hard pull, do not hurt the young mushroom, pick mushroom bed after harvest, dig mushrooms Head, picking rotten mushrooms. 2, mushroom mushrooms shrinking death 1 this situation can not be remedied, the only feasible way is to purchase the appropriate age species, that bacteria age within 3 days of healthy bacteria species; 2 control of temperature changes, the range should not be too large, mushroom formation Must not spray water to the mushroom bed; 3 material should be fermented and sterilized before entering the bed. If the bed has fleas, you can spray 0.1-0.2% of dichlorvos and cover it with a thin film when it is not mushrooming. 3, prevention and treatment of spores and other bacteria 1 use fresh, clean, mold-free culture materials; 2 before cultivation, culture materials should be exposed to the sun for 2-3 days, before sowing with 1-2% lime water; 3 ingredients To control the proportion of nitrogen in the material, the total amount of bran or barley is not more than 15%; 4 if it is used before indoor cultivation with benzalkonium disinfecting, fumigation with formaldehyde for 3 days (formaldehyde dosage 40 ml per cubic meter, formaldehyde 20 grams of potassium permanganate should be added); 5 Cultivation materials must first be stacked and fermented or sterilized with steam so that the stock temperature can reach 75°C and 7 days can kill the bacteria; 6 The water content of the culture can not exceed 95% After sowing, it is necessary to cover the membrane, after opening the window for ventilation, to reduce the ammonia content; 7 to increase the PH, PH is preferably 8.5 in the growth phase, the PH of the fruiting body can not be lower than 7.5; 8 before the cultivation site to be strictly washed, Disinfect, wash with PH9 lime water, spray with 50% wettable powder thiophanate 1000 times or 25% wettable powder carbendazim 300-500 times; 9 improve the inoculation method, will be three quarters of bacteria and Mix the material and spread it, and cover the remaining quarter of the bacteria. The surface of the material, and finally pressed properly, can control the pollution of Coprinus agaricus; 10 regulate the temperature and humidity; (11) If you have the raw material of Coprinus comatus, one is immediately unplugged by hand, and the second is to use 50% lime water for local disinfection. (12) After the first tidal mushroom is harvested, 3% lime water is sprayed on the material to adjust the pH to prevent the occurrence of comatus; (13) 5% of alum water mix or spray can effectively control or reduce the spooky umbrella happened.
