In autumn and winter last year, the mushroom production in Pleurotus ostreatus was more frequent, and it occurred in spring and summer this year. The symptoms of fungal infection were as follows: germ seed germination was normal, food intake was slower than normal, and species blocks showed radial growth. When the length of mycelium was 4 to 5 cm, mycelium was gradually sparse from the seed block, and the tip bacteria were found. Silk is thicker, thicker and continues to develop. The back of the silk is faded and sparse. Finally, the entire surface of the bag is slightly gray or even sterile. 40 days after sowing, the fungus bag was grayish white, no normal white, no thick mycelia, more than 50 days after the mushroom, barely bud, it is rare. Background of the problem: cottonseed husk raw materials, in addition to conventional lime powder and other accessories, the addition of conventional amounts of clomazone, no longer use any other drugs; seeding rate of 10% to 15%, microporous or mesopore bacteria, seed blocks The germination was normal; the tip mycelium was normal, and the density and whiteness were slightly poor. The actual test: The moisture content of the base material is basically suitable, the surface mycelium is scarce, and the mycelium of the mushroom can be seen through experience, but it is delicate and less; the open bacteria bag has obvious bad gas, more pungent pungency, spicy, and rot. Mixed taste; mycelium in the bag is scarce, but there are obviously hyphae connected, so that the base material agglomeration, but loose; and rule out drug reactions and other factors. In numerous telephone consultations, Mongnien’s friends are more likely to believe that it is a nematode. Actual inspection: There were no nematodes on microscopic examination, no insect pests such as mushroom mosquito larvae or cockroaches were observed, and analysis was conducted based on the analysis of hyphae to eliminate the hazards of insects; observation of several typical bags of bacteria except for a few Trichoderma, Aspergillus spots, production No large-area pollution was found in the area; however, after a period of “removal of bacteriaâ€, Trichoderma and other bacteria will soon occupy the surface of the material. Diagnosis: The main cause is poor ventilation in the fungus shed, which results in a high concentration of carbon dioxide in the shed; the secondary cause is the lack of nutrients in the basal and the aging of the strains. Treatment methods: play the development of bacteria shed ventilation holes, so that ventilation inside the shed; the use of a diameter of 12 mm steel bars, longitudinal holes to the bag 2 to 4, the steel rod rotating out to maintain the aperture; bacteria bags around the hole, each Bags of about 30, toothpick can be directly punctured plastic film; try to increase the temperature of the bacteria shed to about 20 °C; after the mushroom spray three-dimensional sperm. Results: After the bacterium bag was treated as described above, the bacterium was recovered within one week, and the hyphae were white. The situation was good. The new fungal hyphae at the efflux site had been covered with dense new hyphae. In response to the above problem of sterilizing bacteria, a special proposal made by Mutong's friends: Prior to production, effective testing of strains and raw materials should be carried out. In particular, the detoxification of strains is one of the key points; the basic materials must be scientifically designed and formulated, and the edible fungi must be added Nutrient nutrients, making it nutritious and balanced, lay the right material basis for the robustness and increased resistance of Pleurotus ostreatus mycelium. Strengthen the killing treatment of mushroom sheds and contaminated bacteria bags, longitudinal punching of the bacterium bags that have undergone bacterium removal and increase of micro-holes, appropriately raising the temperature inside the shed, reducing the humidity, and restoring the growth of mycelium as soon as possible, according to the local environment In the situation, during spraying period every 3 to 7 days, spray all over again and again to a traceless or Saibai 09 solution to ensure the smooth development of the bacteria. Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
