The scraping of mushroom noodles can gain weight.
After two crops of Pleurotus ostreatus harvested, there are often some bad phenomena, such as serious drying hardening, poor air permeability, weak mycelium aging and so on, so as to delay the time of mushroom production, reduce the yield of mushroom body, and even not produce mushroom. Scraping bacteria on the material surface can better solve this problem, and it will have a good effect on increasing production.
The method of scraping the material surface is as follows: for the material surface which is seriously hardened and the bacterial skin is too thick, a layer of aging bacterial skin can be scraped off completely and thinly. For the material surface with slight hardening and thick bacterial skin, many small ditches can be drawn vertically and horizontally with iron wire to expose the hyphae. When cultivated in the border bed, you can sweep the bed back and forth with a bamboo broom until the old bacterial skin is scratched and the hyphae inside is exposed. If planted in a bag, the old hyphae at both ends can be scraped off. By scraping bacteria, it can obviously stimulate the differentiation of primordium and promote the growth of mycelium. Generally, new mushroom buds appear after 7-10 days.
But it should be noted that after scraping the material surface, the old fungus skin should be cleaned up so as not to produce miscellaneous bacteria. At the same time, the exposed new material should be pressed flat in order to produce mushrooms neatly. In addition, water should not be sprayed until the growth of the mycelium is restored.

Measures for the treatment of green mold of Pleurotus ostreatus
Reduce the temperature and humidity of the mushroom room, increase ventilation, and cover the mold with plant ash to prevent the spread of mold spores. First spray fumigation with 3% Lysol solution or 3% formaldehyde solution, and then wash the mold with 1% potassium permanganate solution. After sprinkling potassium permanganate particles on the mold, spray water on the periphery of the mold. Wash the mold place with 9 parts of quicklime and 1 part of carbendazim mixed with proper amount of water. Soak the mold in 5% limewater, remove the limewater after the mold disappears, and add new materials. Inject it with 200 grams of carbendazim solution.

Control measures of truffle disease of Pleurotus ostreatus
(1) the symptom of the disease is similar to that of Pleurotus ostreatus hyphae, which is indistinguishable to the naked eye; it can go deep into the substrate, compete with Pleurotus ostreatus hyphae for nutrition, water and bottom-up space, and inhibit the ability of Pleurotus ostreatus to produce mushrooms. Its physiologically mature mycelium forms ascomycetes on the mushroom surface of the culture material, especially in the area around the fungus column in contact with the soil during border planting; the ascomycetes in groups or aggregates are brain-shaped wrinkles in shape, very similar to walnut kernels removed from astringent skin, wrinkled and not stretched; at the beginning, most mushroom farmers mistakenly think that Pleurotus ostreatus is budding.
