Production Management Methods and Technical Key Points for the Growing Period of Oyster Mushrooms
After the large-scale formation during the mulberry stage and the brief coral stage, the mushroom bodies gradually enlarge and enter the growing period. At this time, management should be strengthened so that the mushroom bodies differentiate and mature within 5-7 days. Specific management measures: ① Ventilation. To prevent deformed or rotten mushrooms caused by excessive stale air in the room, ventilate 3-4 times daily to supply fresh air. ② Moisture retention. Adequate air humidity is an important condition for the enlargement of the mushroom bodies, so mist water should be sprayed in the room 4-5 times daily. However, avoid water accumulating on the caps, so as to prevent curling. The relative air humidity should be maintained at 9

How to prevent and control soft rot in oyster mushrooms? These methods are very practical
Dong Yushan from Ligou Town, Pingyin County, Shandong Province, wrote in: "The oyster mushrooms grown in my town and the surrounding townships develop small yellowish-brown spots during the fruiting stage, especially when the fruiting bodies are about 1 cm in diameter, which then rapidly expand, and finally the entire fruiting body turns brown, becomes soft and sticky, and ultimately rots. Even though the mycelium inside the mushroom log is still very dense and white, it is very difficult to get another flush. What disease is this? How should it be prevented and controlled? Host Yangguang replies as follows: The situation reported by this friend also occurs quite often in other areas. Judging from the described symptoms,

What to Do When Oyster Mushrooms Get Soft Rot Disease? Detailed Prevention and Control Methods
Symptom manifestation is mainly shown by the white mycelium of oyster mushrooms growing in a spider-web-like pattern on the surface of the bed, rapidly spreading, covering the bed surface, and surrounding the fruiting bodies. Once the base of the fruiting body is surrounded by mycelium, it becomes infected; the pathogen spreads upward along the stipe, and finally the fruiting body stops growing, its color becomes dull, and it rapidly softens, turns yellow, turns brown, and then rots. Prevention and control methods: First, strictly treat the mushroom shed. Before the mushroom shed is put into use, spray it with Mushroom Disease Eliminator King, keep it sealed for two days, then spread lime powder on the ground at 250 grams per sq m. Second, during the spawn-running period

Management Methods and Technical Key Points for Oyster Mushrooms After Casing Soil
1. Heat preservation and moisture retention: After the oyster mushroom substrate logs are covered with soil, keep the shed temperature at 10°C-15°C, and keep the bed surface moist for about 15 days, until granular mushroom buds appear on the bed surface. After 3-4 days, when the caps grow to 1 cm in diameter, ventilate appropriately for 1 hour at noon. After the mushroom clusters grow larger, ventilate for 1 hour each morning and evening until harvest. Do not water during the growth period of the oyster mushroom fruiting bodies, so as not to drown the young mushrooms or splash soil onto the gills, which would affect the quality and edible value of the oyster mushrooms. 2. Harvesting: Harvest when the oyster mushroom caps curl inward slightly or are flat. When harvesting, support the lower left side of the mycelium with your left hand,

What to Do When the Surface of Oyster Mushroom Substrate Turns Black? Cause Analysis and Control Methods
The main causes of blackening on the substrate surface and the control methods are: (1) Oyster mushroom mycelium soaked in water for a long time causes rot and blackening. In this case, the condensation water on the substrate surface should be absorbed and dried promptly. If it is grown on beds, excess water at the bottom should also be absorbed and dried promptly. (2) Contamination by foreign microorganisms and breeding of insect pests cause blackening. When blackening occurs, pests must be controlled or the affected part dug out promptly to prevent it from spreading.

Control Methods for Rust Spot Disease in Oyster Mushrooms
The rust-colored or dark brown spots appearing on the caps and stipes of oyster mushrooms are called rust spot disease of oyster mushrooms. This disease is a bacterial disease that easily occurs during the fruiting body growth stage of oyster mushrooms. The pathogen causing this disease is a species of Pseudomonas bacteria that is extremely widely distributed in nature. In the early stage of the disease, the spots are only the size of a needle tip and light in color, generally not affecting commercial value. As the disease worsens, the spots rapidly enlarge and their color continuously deepens, often appearing oval or spindle-shaped, or connecting with each other to form irregular large patches, with rust-yellow discolored areas around the patches.

Detailed Explanation of Indoor Three-Dimensional Cultivation Methods for Oyster Mushrooms in Winter
Place the plastic tubes filled with oyster mushroom spawn (cylindrical in shape) indoors or in a mushroom cellar. When the room temperature is 24°C-25°C, they can only be arranged in a single row and single layer for mycelial running. When the room temperature is around 20°C, they can be arranged in two or three rows in a single layer. When the room temperature is 10°C-15°C, they can be stacked to a height of 1 m-1.5 m, and every 10-15 days, the upper and lower positions should be swapped to make the temperature uniform in all parts and the mycelial running consistent. During this period, keep the room as dry as possible. When the indoor humidity reaches above 80%, it is best to adopt the two-level cultivation method of mycelial running above ground and fruiting underground. Maintain

Detailed Explanation of Simple Insulation Methods for Oyster Mushrooms in Winter
In the process of cultivating oyster mushrooms, the author has explored a set of simple insulation methods through practice, which are introduced as follows: In late autumn, bagging and inoculation for oyster mushroom cultivation should begin, so that by the time the temperature drops and turns cold, half a bag of mycelium can already be well developed. When such mushroom bags are subjected to insulated cultivation, the bags can quickly become fully colonized with mycelium. For those who have not started bagging and inoculation in advance, they can carry out one-time heated mycelium development. After the temperature drops, densely stack the mushroom bags that have developed half a bag of mycelium, stacking them as high and as wide as possible to facilitate heat accumulation, warming, and insulation. Stacking method: every 4 rows form a section, with 7 mushroom bags per row

Cause Analysis and Diagnosis and Treatment Methods for Mycelial Regression in Oyster Mushrooms
In the autumn and winter seasons of last year, mycelial regression occurred frequently in oyster mushroom production, and there were also sporadic cases this spring and summer. The symptoms of mycelial regression are as follows: the spawn blocks germinate normally, the colonization of the substrate is slower than normal, and growth from the spawn blocks is radial. When the mycelium length reaches 4-5 cm, the mycelium gradually becomes sparser starting from the spawn block, while the mycelium at the growing tips is denser and denser white and continues to develop, with the mycelium behind it fading and thinning accordingly, until finally the surface of the entire mushroom bag appears slightly grayish-white or even devoid of mycelium. At 40 days after inoculation, the mushroom bags appear grayish-white rather than the normal pure white, and no

Indoor Cultivation Techniques for Oyster Mushrooms: Detailed Explanation of Compounding, Filling, and Spawning Methods
1. For the formula of the growing substrate, cottonseed hulls are generally the better choice, because cottonseed hulls are relatively rich in nutrients and also have good air permeability. Choose dry cottonseed hulls with no mold, and it is best to sun-dry them for 2-3 days in advance. The raw material formula is: 100 kg cottonseed hulls, add 2 kg superphosphate, 3 kg gypsum, 0.2 kg carbendazim, and add about 150-160 kg water (depending on how dry the cottonseed hulls are and how much cotton lint they contain). Mix the above raw materials thoroughly, and adjust the moisture until it feels right when squeezed tightly by hand: water droplets appear between the fingers but do not drip
