On 9 october 2025, the rains continued, the temperature fell faster due to more than a few days of rain in the south of the river, and problems were encountered at many mushroom plantations, as manifested in the thinning of the fungus cover, the length of the bacterium handle, the presence of sawnocks on the edges of individual baptisms, some of which were larger, and some of the entity's original base was yellow mushroom disease, which seriously affected the production, appearance and quality of mushrooms, thus affecting the price of the fungus and the income of the mushroom farmers。
According to the chief of the zheng county integrated experimental station of the national system of technology for the food industry, dr. Conwewey of the henan department of science and technology of the henan department of agricultural research institute of possibilities, and the vice-researcher of the yuan branch of industrial science and technology of henan province, the main reasons for these problems are the continuous rainy weather, reduced air pressure and reduced air density, leading to a relative decrease in oxygen content. In addition, the relative humidity of the air increases the water molecular content in the air, reduces the rate of oxygen diffusion, further hinders the circulation of the current, leading to the lack of circulation of the air in the sheds, resulting in normal ventilation measures that are no longer able to address the problem of over-concentration of carbon dioxide in the sheds, and the abnormal development of pericarcular cells to form a scavenger lid and the strains to grow. Second is the lack of light due to continuous cloudy weather, which overstretches the bacterium, and the abnormal development of the baptism leads to thinning and unsightened. The third is that the temperature differential between the pre- and post-development stages of the fungus is greater, such as sharp cooling, and can easily form a sawn cortex。
In response, the experts proposed the following responses: first, to increase ventilation by increasing ventilation by increasing ventilation and improving ventilation on both sides of the shed as much as possible; second, to reduce the relative humidity of the air during consecutive periods of rain, to install two-way exhaust fans or large-scale wind turbines, to facilitate air circulation in the mushroom shed through mechanical ventilation, to reduce co2 concentrations and the relative humidity of the air; third, to make appropriate light with dispersed light sources or artificial light (e. G. Led light belts); fourth, to remove mushroom burning or remote burial in a timely manner after the onset of a yellow mushroom disease, to treat fungicides in and around the fungus bags, e. G., 0. 025 per cent of bleaching powder solubles, and pharmaceutical agents specializing in the treatment of yellow mushroom disease; and fifth, to use a variety of prophylactics, antigens, etc., without reference or discretion.
