Using mushroom starter to produce high yield, high quality and save time
The use of fermentation auxiliaries to produce edible fungus culture materials has the advantages of fast fermentation and good fermentation, which can ferment at both high temperature and low temperature, which greatly shortens the fermentation time, reduces the labor intensity and reduces the production cost. It also has the characteristics of widespread fermentation and strong adaptability (it can ferment almost all the organic matter that needs to be fermented, and it has loose requirements on environmental conditions) It can be widely used in the fermentation treatment of various culture materials of many kinds of edible mushrooms, such as bisporus mushroom (white mushroom), big fat mushroom (double ring mushroom), Pleurotus ostreatus (Pleurotus ostreatus), Ji mushroom (Pleurotus ostreatus), straw mushroom (rice straw mushroom, Chinese mushroom), silver straw mushroom, slippery mushroom (true rare mushroom), chicken leg mushroom, Agaricus blazei Murrill (small pine mushroom, Brazilian mushroom) and so on.
First, rapid fermentation, saving time and cost. Fermentation aids can make the temperature of edible mushroom culture material rise rapidly to 60: 70 ℃ within 2-3 days, and the start-up temperature is above 15 ℃). Generally, it can shorten the fermentation time of edible mushroom culture material by more than half, shorten the fermentation time of mushroom culture material by more than 10 days, and shorten the fermentation period of culture materials such as Pleurotus ostreatus, straw mushroom and Coprinus comatus by 3-4 days. It reduces the number of overturns, reduces the labor intensity, and saves a lot of manpower, material resources and other economic costs.
Second, improve efficiency and increase output. Fermentation auxiliaries can quickly and effectively degrade and transform material nutrients, make nutrients more balanced and rich, and make edible fungi absorb as soon as possible, reduce loss and waste, and greatly improve nutrient utilization. Compared with the conventional treatment, the yield of edible fungi can be increased by 20% and 30%.
Third, kill insects and pests and improve quality. Using fermentation auxiliaries to ferment edible fungus culture materials, beneficial functional microorganisms can multiply massively and rapidly, produce high temperature and high heat, and quickly kill most pests, eggs and miscellaneous bacteria that harm edible fungi. In the process of functional microbial reproduction, beneficial microbial "dominant microflora" is formed, which forms an ecological protection mechanism of producing "bacteria" (harmful bacteria) with "bacteria" (beneficial bacteria), and can secrete a large number of enzymes, antibiotics and other metabolites, which can comprehensively inhibit the growth and reproduction of miscellaneous bacteria, greatly reduce the use of chemical pesticides and fungicides, comprehensively improve the taste, flavor, appearance and other quality of edible fungi, and improve the product grade.

Control of spot disease of Pleurotus ostreatus
1. The main symptoms of this disease are damage to leaves and petioles. Leaf disease spot yellowish brown to brown, showing polygonal, oval or irregular shape, slightly wheel-shaped, disease spot surrounded by yellowish green or green-brown halo, disease spot sometimes linked to each other into a large disease spot, serious can make the leaves yellow and dry. Petiole disease often produces short brown spots, and gray mold grows on the surface of the spot when the humidity is high. two。 The route of transmission and the regularity of the disease is caused by the infection of Cercospora, a subphylum fungus, which is mainly caused by mycelium and conidia.

Mushrooms appear on the side of the bag and there are many deformities
In the process of sterilization, the bacterial bags squeeze each other and the round bags are deformed, resulting in a gap between the cultivation material and the bag, which provides air and space for the twisting of hyphae. Coupled with low temperature, light stimulation and mechanical stimulation (such as inverted bag, etc.), the hyphae on the side of the bag were twisted to form primordia and developed into fruiting bodies. Due to the limitation of plastic bags, this kind of mushroom is all deformed. If this happens, the mushroom bud should be pinched in time to stop its growth, so as not to cause more waste of nutrition. The fruiting body is small and the commodity rate is low:
