How to keep button mushrooms fresh? These three methods are very practical
In order to extend the storage period of mushrooms, maintain their quality, color and flavor, and improve the cultivation benefits of mushrooms, the preservation techniques for mushrooms are introduced below. Mushroom growers can choose and apply them according to their own actual conditions. 1. Low-temperature preservation method. Practice has proved that low temperature can keep mushrooms fresh and of good quality. The method is: after mushrooms are harvested, their humidity is 90-95%; at this time, storing the mushrooms at 0-3°C can achieve the purpose of preservation. It is worth noting that during the preservation period, the temperature of the mushrooms should be kept

Detailed Explanation of Key Points of Button Mushroom Preservation Techniques
To extend the storage life of button mushrooms and maintain the quality, color and flavor of the fruiting bodies, the preservation techniques are introduced here, and farmers may choose appropriately according to their conditions. 1. Controlled atmosphere preservation. At room temperature, use breathable plastic bags for packaging, keep the oxygen inside the bag at about 1%, and control carbon dioxide at 10%-15%, which can keep button mushrooms fresh in color and excellent in quality within one week. 2. Low-temperature preservation. Low temperature can maintain the freshness and excellent quality of the fruiting bodies. After harvest, 90%-95

Key Management Points for Spring Button Mushrooms and Post-Harvest Handling Methods
The button mushroom (Agaricus bisporus) is currently China's largest export earner among edible fungi, with main production areas in Fujian, Shanghai, Hunan, Guangxi and other provinces. At present, it is the spring mushroom management stage, and some key management techniques for this stage are briefly introduced below: Spring mushroom management accounts for about 30% of total yield. After mid-March, as temperatures gradually rise and stabilize above 10°C, the water content of the casing soil can be gradually adjusted to sufficient levels to meet fruiting needs. When adjusting water, first spray the clear supernatant of lime water at pH 8-9; when the temperature is below 15°C, top-dressing fertilizer can be applied together with spraying. Around April

Detailed Explanation of Button Mushroom Cultivation Techniques in Rice Fields (Part 5)
V. Integrated Pest and Disease Control. Integrated pest and disease control should adhere to the principle of prevention first, with prevention being more important than treatment, and to the principle of combining agricultural control, physical control, biological and ecological control, and chemical control. The use of highly toxic and high-residue pesticides must be eliminated, and no pesticides should be used during the mushroom harvesting period. Diseases and deformed mushrooms caused by environmental factors or improper technical management (such as red-foot mushrooms, landmine mushrooms, big-ball mushrooms, scaly mushrooms, etc.), as well as weed fungi (such as Coprinus mushrooms, etc.), should be controlled primarily through integrated measures. Main measures: First, the compost formula must be accurate, and the material

Button Mushroom Spawning Methods and Technical Key Points
(1) Spawning date. In each region, an appropriate spawning period must be chosen according to local climatic conditions. The standard for the optimal spawning period is: during the mycelium-running stage of the compost, the natural temperature should be 24-26°C as far as possible. In the Yangtze River basin area, the spawning period is in early to mid-September; in Shanghai and areas near Shanghai, the optimal spawning period is September 8-12. If spawning is too early, temperatures above 28°C are often encountered after spawning, causing the spawn not to germinate and to die; if spawning is too late, the number of days suitable for fruiting is shortened, making it difficult to obtain high yields. (2) Before spawning

Key Technical Points for Harvesting and Processing Button Mushrooms
The right time to harvest mushrooms is when the partial veil has not yet broken, the cap has not yet opened, and they have reached the size required by purchasing specifications. Harvesting too early results in small mushrooms and low yield; harvesting too late inhibits the formation and growth of the next flush, prolongs the growing cycle, and also affects mushroom quality. This is especially true when the temperature is relatively high (around 20°C) and there is a heavy flush, as the mushrooms very easily become thin mushrooms or open-cap mushrooms. For commercial mushrooms intended for canning, they generally must be harvested promptly once the cap diameter reaches 2-4 cm. Normally they are harvested once a day, but during the peak production period they must be harvested twice a day to prevent the caps from opening and

Detailed Explanation of Key Management Techniques for Spring Mushrooms of the Button Mushroom (Agaricus bisporus)
After the autumn mushroom season ends, following overwintering management, the mushrooms that fruit again in spring are known as spring mushrooms. Because they have gone through the autumn fruiting period and the low-temperature winter stage, most of the nutrients in the compost have been consumed, and the compost mycelium has also been affected by low temperatures; therefore, the vitality of the spring mushroom mycelium is relatively weak, and its fruiting capacity is noticeably lower than that of autumn mushrooms. At the same time, spring temperatures change from low to high, and the number of pests and diseases in the environment gradually increases. Therefore, spring mushroom management must, according to the climatic conditions at the time, effectively regulate the three factors of temperature, moisture and air in the mushroom house, and carry out pest and disease control, etc.

Key Management Techniques for Autumn Cropping of Agaricus bisporus (Button Mushroom)
Autumn mushroom management should be based on the environmental requirements for mycelial and fruiting body growth, correctly handle the contradiction between outside temperature and indoor temperature, and flexibly manage bed watering and mushroom house ventilation under natural temperature conditions to meet the requirements for mycelial and fruiting body growth. 1. Mycelial growth in the casing soil layer: After the moisture of the casing soil layer has been adjusted, the stage of mycelial growth management in the soil layer begins. The management principle for this stage is: under the condition of maintaining relatively constant air humidity in the mushroom house (80%-85%) and mushroom house temperature (20-22°C), carry out appropriate ventilation to ensure the mycelium grows fully and well within the soil layer.

Control Methods and Technical Key Points for Physiological Diseases of Button Mushrooms
Button mushrooms are relatively sensitive to their environment. A poor cultivation environment will hinder their normal growth and development, produce various abnormal phenomena, and lead to reduced yield and lower quality. Common physiological diseases of button mushrooms include excessive mycelial growth, hard opening of the caps, thin-skinned early opening, and the appearance of soil-level mushrooms and hollow-stemmed white-core mushrooms. They are described below: Symptoms of excessive mycelial growth: after the mushroom bed is cased and watered, the fluffy mycelium of the button mushroom will continuously grow toward the surface of the fine soil. In severe cases, it will form a fine, water-impermeable mycelial mat, thereby delaying the time of fruiting and reducing the mushroom

Detailed Explanation of Key Techniques for Preventing and Controlling Mushroom Dead Button Disease
Mushroom dead button refers to the phenomenon in which small mushrooms on the mushroom bed shrink, turn yellow, and die. The appearance of withered mushrooms in patches or batches can severely affect yield. 1. Causes of dead button: ① Temperatures too high in late autumn (exceeding 23°C), or during the spring fruiting period when temperatures rise too high and too quickly (several consecutive days at 21°C), causing small mushroom buttons to shrink and die from nutrient deficiency. ② Poor ventilation in the mushroom house, insufficient o2 and excessively high co2 concentration, and the heat generated by metabolism cannot be dissipated quickly, causing small mushroom buttons to die in batches from insufficient oxygen supply or high temperature. ③
