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.

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,

How to prevent fish from gasping at the surface? A detailed guide to practical and effective measures
Discharge an appropriate amount of pond water and add fresh water; the suitable time for adding water is around 2-3 p.m. Use aerators reasonably, stop fertilizing, and control fish feeding. Splash quicklime water in small amounts several times to adjust the pH of the water body. Use chlorine dioxide twice in succession to disinfect the water body; before disinfection, an appropriate amount of oxygen enhancer and microecological preparations may be applied.

How to judge the severity of fish gasping at the surface
To judge the severity of fish gasping at the surface, the main criteria are the time when the fish begin to gasp, the location of the gasping, the size of the water surface area where they gasp, and the species of fish gasping. 1. Dark gasping. This generally occurs when it is already daylight but the sun has not yet risen; the fish move about on the water surface in the center of the pond and on the upwind side, and bursts of splashing water can be seen. At this time the dissolved oxygen content of the pond water is 2-3 mg/L, which is normal gasping. 2. Light gasping. This mostly occurs at dawn; the fish are on the water surface in the center of the pond and on the upwind side, while wild trash fish gasp at the pond edge.
