Causes and Countermeasures of delayed emergence of Pleurotus ostreatus mycelium after eating food
In the cultivation of Pleurotus ostreatus, it is sometimes encountered that the mycelium of some bags or bricks grow well, but do not produce mushrooms for a long time after eating completely. The main reasons and remedial measures are as follows:
1. The variety of Pleurotus ostreatus does not match with the selection of season. The temperature gap between the temperature type of strain and that of cultivation is too large, which can also be said to be the improper choice of sowing time. If the medium and low temperature type of Pleurotus ostreatus is sown at the turn of spring and summer, it is difficult to produce mushrooms in the high temperature season after the mycelium is full. Remedy: dig grooves in the cool place to cover the soil over the summer, remove the covered soil when the autumn is cool, and carry out mushroom management, which can reduce the loss.
2. Too much nitrogen-rich substances (wheat bran, rice bran, urea, etc.) were added in the culture material, and the relative carbon was insufficient, so the mycelium grew too long and formed a very thick quilt, which hindered the reproductive growth, delayed the mushroom production and seriously affected the yield. Remedy: gently scratch the quilt with iron strips and scratch it (the same as the scratching treatment in the cultivation and management of Pleurotus ostreatus), then strengthen ventilation and spray 0.5% glucose solution or 1ppm triacontanol solution and other carbon-containing substances to adjust the ratio of carbon and nitrogen, supplemented by temperature difference stimulation, appropriate ventilation and light transmission, can promote mushroom budding.
3. When the mycelium just grew well, some strains grew sporadic mushrooms, mistakenly thought that they had produced mushrooms normally and opened the bag prematurely, and opened the film prematurely, coupled with higher ambient temperature and lower humidity. A dry and hard bacterial film is formed on the mouth of the bacterial bag or on the surface of the bacterial brick, so that the mycelium can not be twisted into primordia and can not bud and produce mushrooms. Remedy: replenish water as appropriate, then use a clean bamboo stick to crisscross the bacterial skin membrane of the material surface, and then add proper ventilation, appropriate amount of light, and temperature difference stimulation to make the mycelium kink out of mushrooms.

The mycelium of Pleurotus ostreatus appears "alopecia spot".
Some of the long hyphae in the culture material, some do not grow hyphae, or long hyphae on the surface but not in the material, which is called "alopecia areata". The main causes are too much water or uneven mixing, insufficient moisture regulation, too large, too thick, too tight, and poor ventilation or overtemperature after sowing. Prevention and control methods: add the right amount of water, mix the material evenly, the block should not be too big, too tight and too thick, always check the temperature of the material, so as not to overheat the fermentation of the culture material itself. due to overtemperature, "alopecia" should be replanted in time, because of moisture.

Disinfection treatment of fill when cultivating mushroom mushroom wall, clean soil must be taken from the fill and disinfected before use. Two kinds of filling should be prepared: one is for edge sealing, and the sticky soil should be selected to prevent the bacterial wall from leaking; the other is for internal filling, and fertile vegetable garden soil should be selected. No matter what kind of soil, dig below 10 cm of the ground surface and bask in the sun for 3-4 days, then add 1% lime and 0.1% carbendazim to mix and disinfect, and add 0.5% phosphate fertilizer to the nutritious soil for internal filling.
