There is an art to watering oyster mushrooms, and mastering the six observations is key
First, observe the climate. In dry weather, water more to raise humidity; in humid weather, water less. Second, observe the water temperature. When the mushroom house temperature is above 25°C, water at night or in the early morning or evening after the air temperature has dropped. Third, observe the mushroom house's moisture-retention performance. Mushroom houses with poor moisture retention need more watering, otherwise less. Fourth, observe the dryness or moisture of the substrate at both ends of the mushroom bag. When the substrate is dry, the amount of water sprayed should be sufficient, and the frequency correspondingly reduced. Fifth, observe the strength of the mycelium. When the mycelium in the substrate is strong, more water should be used, and the water for pinning and for the flush transition should be heavy; otherwise, it should be light. Sixth, observe how many mushrooms there are. When there are many and large mushrooms on the substrate surface, the water requirement is

Spraying oyster mushrooms with cooled boiled water can significantly increase yield
Spraying cooled boiled water at different stages of oyster mushroom fruiting can increase the biological conversion rate by 33%, and oyster mushrooms sprayed with cooled boiled water flush faster, fruit evenly, and have thick, plump caps. After the oyster mushroom mycelium has fully colonized, remove the plastic film and spray the mushroom bed and the surrounding walls once with cooled boiled water so that the relative air humidity reaches 80-85%; when coral-like primordia appear in large numbers, as the fruiting bodies gradually grow, spray cooled boiled water 3-5 times a day to raise the air humidity to 95%. When spraying, use a fine mist; do not irrigate heavily, so that standing water does not cause mushroom death

What should you do if herbicide is accidentally mixed into oyster mushroom (Pleurotus ostreatus) substrate?
Herbicide should never be mixed into the substrate when growing oyster mushrooms. As for what adverse effects mixing herbicide into the substrate may have on the growth of oyster mushroom mycelium, we have not yet carried out experiments in this area. I think that mixing 50 grams of herbicide into 2000 jin of substrate is not a low concentration; even if it does not affect mycelial growth, at the very least herbicide residues will accumulate in the oyster mushroom fruiting bodies, making it very difficult to guarantee the safety and hygiene of the product. The solution is to repeatedly rinse the herbicide-containing substrate with water (5-6 times), then drain off some of the excess water, add an appropriate amount of carbendazim (reduced by about 20% from the original amount), pile it up for fermentation, and then use the original method for inoculation and cultivation.

Adding table salt to oyster mushroom substrate can increase yields
In oyster mushroom cultivation, using carbendazim to control contamination by foreign fungi is effective, but pesticide residues remain in the mushrooms, which is harmful to human health, and the cost is relatively high. According to experiments: when cultivating oyster mushrooms on raw substrate, adding 1.5 kg of table salt per 100 kg of dry substrate (dissolved in advance in a measured amount of water) and mixing thoroughly can prevent infection by foreign fungi and also bring mushrooms out 5-7 days earlier. At the same time, because table salt is rich in sodium, calcium, magnesium and other metal ions needed for oyster mushroom growth, if a 10% salt solution is sprayed in the early stage of fruiting body differentiation and after each flush is harvested, the mushrooms can be free of pesticide residues and their quality

How to Prevent Sour Rot in Oyster Mushroom Substrate? Detailed Practical Measures
Recently the weather has been hot, rainy and humid, which easily breeds spoilage bacteria, and a moment of neglect can cause losses to oyster mushroom production. To prevent and control sour rot in oyster mushroom substrate, the key is to grasp six words: fresh, sparse, increase, air, dark, lower. Fresh: the substrate used, such as rice straw, corn stalks, wheat straw, etc., should be fresh and free of mold, and should be exposed to the blazing sun for 3 days before use. Sparse: use relatively small plastic bags with a diameter of 20 cm or less to cultivate oyster mushrooms, and during the spawn-running period stack only 1 layer, without overlapping, to help dissipate heat. Increase: when mixing the substrate, use lime

How to keep oyster mushroom substrate moist? Sharing practical tips
1. Moisture retention by casing soil over a wall of mushroom logs. Inside the shed, lay a soil ridge 15-20 cm thick along the length of the mushroom bags, take the bags that are fully colonized and about to fruit out of their plastic bags, and arrange them neatly on the soil ridge. For each layer placed, cover with soil 3-4 cm thick, spray water on both sides of the soil and smooth it with mud. Then arrange the second layer of mushroom logs and cover with soil; up to 6-9 layers can be placed, and the topmost layer must still be covered with soil and smoothed. After the wall is built, spray one heavy watering so the casing soil absorbs enough water. After that, spray water every day to keep the casing soil moist, and manage fruiting as usual. This method can increase oyster mushroom yield by 50%

What to Do When Oyster Mushrooms Grow Green Mold? Detailed Treatment Measures
Lower the temperature and humidity of the mushroom house, increase ventilation, and cover the moldy spots with plant ash to prevent mold spores from spreading through the air. First fumigate the room with a 3% Lysol solution or a 3% formaldehyde solution, then wash the moldy spots with a 1% potassium permanganate solution. After sprinkling potassium permanganate granules on the moldy spots, spray water around the outer edge of the mold. Take 9 parts quicklime and 1 part carbendazim, mix with an appropriate amount of water, and scrub the moldy spots. Soak the mold with 5% limewater; after the mold disappears, drain off the limewater and add fresh substrate. Inject a 1:200 kemeiling solution

Scraping the mushroom bed surface of oyster mushrooms can increase mushroom weight
After two harvests of oyster mushrooms, the bed surface often becomes severely dry and compacted, with poor air and water permeability, and the mycelium becomes senescent and weak, which delays the fruiting time, reduces mushroom yield, and may even result in no mushrooms at all. Scraping the bed surface can effectively solve this problem and produce a very good yield increase. The method for scraping the bed surface is: for a severely compacted bed surface with an overly thick mycelial skin, scrape off a thin layer of the aged mycelial skin over the entire surface. For a slightly compacted bed surface with a relatively thick mycelial skin, use a wire to scratch many small crisscrossing grooves until the mycelium is exposed. For ridge-bed cultivation,

What are the control measures for truffle disease in oyster mushrooms?
(1) Disease symptoms The mycelium of this fungus resembles that of the oyster mushroom and cannot be distinguished with the naked eye; it can penetrate deep into the substrate, competing with the oyster mushroom mycelium for nutrients, water and space from the bottom up, inhibiting the mushroom's fruiting capacity. Its physiologically mature mycelium forms ascocarps on the fruiting surface of the substrate, especially in bed cultivation where it occurs over large areas in the zone where the mushroom columns contact the soil; the clustered or grouped ascocarps are shaped like brain-like wrinkled masses, closely resembling walnut kernels with the bitter skin removed, all wrinkled and not spread out; when they first appear, most mushroom growers mistake them for oyster mushroom pinheads, but

How to prevent and treat the death of oyster mushroom mycelium during the growth period?
Vigorous oyster mushroom mycelium is white like cotton fluff, thick and dense, advancing forward in a fan shape. In some cases, about 10 days after inoculation, the mycelium is suddenly found to turn yellow and gradually die off and disappear. Regarding this phenomenon, some mushroom growers believe that the higher the water content in the compost, the higher the yield, so they increase the water content when mixing the substrate. Some growers also do not understand the meaning of water content, mistakenly taking a compost water content of 65% to mean adding 148 kg of water per 100 kg of substrate. The correct method for calculating water content should also include the water contained in the compost itself; generally, the compost itself has a water content of
